presented eleven sets of evidences to show that (a) The Illusion Theory is wrong for mysteries on hundreds
of Gravity Hills and in several known Mystery Spot areas on earth surface, and (b) These mysteries are real
and are caused by existence of strong abnormal local gravity with a strong horizontal component of local
gravity at these special locations of Gravity Hills and Mystery Spot areas. Such results lead into an important
and very challenging question of "What is source of such strong abnormal local gravity?"

This challenging question is the driving force for my 23-year research on Gravity Hills and Mystery Spot areas
to find the answer. My 23-year research indicates that:

(c) The observed Shrink-and-Grow Mystery and the slow movements of scenery in Mystery Spot areas seem
to suggest that high concentration of Type B dark matter can shrink space in its vicinity. The important
implication of this discovery to dark energy is described in my Web Page (6):

Web Page (6): http://
www.shltrip.com/Space_Shrinking_Capability_of_Dark_Matter.html

(d) the mass densities of our familiar ordinary matters on or near earth surface are too low by at least three
orders of magnitude and are unable to produce those observed mysteries, and

(e) the source of the strong abnormal local gravity at each of those special locations is a fountain of Type B
high density dark matter. The mass density of the core of the fountain of dark matter is at least 1,000 times
greater than that of average ordinary matter on or near earth surface. Furthermore, each fountain of high
density dark matter is supported by two vertical narrow streams of Type B high density dark matter trapped
and oscillating in earth gravity well. These key results plus some more important information enables me to
develop the dark matter based theory of Mystery Spot areas and Gravity Hills.

There are two types of dark matter: Type A low density dark matter is in the galaxy dark matter halo
surrounding our Milky Way Galaxy or other galaxies, and Type B dark matter that can clump together into
much higher density because Type B dark matter can shed more energy through certain dissipative
processes involving yet unknown dark interaction processes (such as dark radiation, or dark light or dark
photon, etc.) in the dark sector of universe. The ability of Type B dark matter with yet unknown interaction
process to shrink space in vicinity is consistent with its ability to clump together into very high density.

This theory shows that the distribution of Type B high density dark matter in the earth is NOT uniform but is
highly concentrated at those special locations of Gravity Hills and Mystery Spot areas.

The important implications of this theory to the direction detection of dark matter on earth in 12 or more deep
underground laboratories are described in my Web Page (3):

Web Page (3): http://
www.shltrip.com/Two_Populations.html

My theory indicates that:

(f) none of these 12 or more deep underground laboratories have detected Type A low density dark matter,
and

(g) the two deep underground laboratories in Italy and in Minnesota, USA have detected Type B high density
dark matter.

The validated successful direct detection of dark matter by human being for the first time will be an important
milestone and accomplishment in science.

1. Introduction

My companion Web Page (1) at:

Web Page (1): http://
www.shltrip.com/Magnetic_Hill.html

presents eleven sets of evidences to show that (1) Illusion Theory is wrong for the Gravity Hill Mystery on
hundreds of known Gravity Hills all over the world and for the Shrink-and-Grow Mystery in several known
Mystery Spots, and (2) These two famous mysteries are real and are caused by the existence of significant
abnormal local gravity at those special locations. (The definitions for Gravity Hill Mystery, Gravity Hills, Shrink-
and-Grow Mystery and Mystery Spots are given in Section 1 in my companion Web Page (1) and will not be
repeated here.) This Web Page (2) will show that the existence of significant abnormal local gravity is an
indication of very high concentration of dark matter at these special locations.

As soon as the stonewall of Illusion Theory is broken down, an immediate and challenging question is “What
is the source of such significant abnormal local gravity at those special locations?”

This important question is a powerful driving force for my 23 year research in finding all the necessary
support information that shapes my hypothesis on “Dark Matter based Theory for Mystery Spots and Gravity
Hills.”

This hypothesis of dark matter based theory provides scientific explanation for these two famous mysteries
with signatures of strong abnormal local gravity in those known Mystery Spots and hundreds of known
Gravity Hills all over the world.

My 23 year research found that the distribution of dark matter particles in earth gravity well is not uniform, but
is highly concentrated in thousands of narrow streams of very high density dark matter oscillating in earth
gravity well. Such unique opportunity of close up investigation of high density dark matters at these Gravity
Hills and Mystery Spots is important to supplement the study of dark matter based on astronomy
observations. In astronomy observations, the galaxies, galaxy clusters and associated dark matter halos are
often many light years away such that it is difficult to discern the fine scale structure in the order of feet in the
distribution of dark matter in the earth or in space.

A serious dilemma exists for many years on why two of the deep underground experiments have detected
dark matter in their dark matter detectors with annual modulation, but such direct detections are not
replicated in ten or more other deep underground experiments at other locations in the world. My dark matter
based theory can resolve this serious dilemma because the distribution of dark matter particles in earth
gravity well is NOT uniform. The probability of detecting dark matter in deep underground laboratories should
vary greatly from one laboratory to another laboratory depending on whether the dark matter detector
intercepts the narrow stream of very high density dark matter or not. With such explanation in my Web Page
(3) listed in the Abstract, this theory is crucial to resolve this serious dilemma and to validate the direct
detection of dark matter in those two deep underground experiments in Gran Sasso National Laboratory in
Italy and in Minnesota, USA.

My hypothesis on dark matter based theory provides predictions and a proposal for the validation of the 17
year results of direct detection of dark matter in the deep underground laboratories in Italy and in Minnesota,
USA. This theory also provides a proposal on what need to be done in selecting other locations in other parts
of the world to be able to replicate the direct detection of dark matter detected in Italy and in Minnesota,
USA. Details of my predictions and proposals are described in my Web Page (3) listed in the Abstract and in
Appendix D of this Web Page (2).

The validated successful direct detection of dark matter in these two deep underground laboratories will be a
major milestone and accomplishment in science.

1.1 Two Types of Dark Matter on Earth

There are two types of dark matter on earth:

Type A low density dark matter is in the galaxy dark matter halo surrounding our Milky Way Galaxy or other
galaxies, and

Hypothesis 1: Type B dark matter can clump together into much higher density because it can shed more
energy through certain dissipative processes involving possibly yet unknown interaction processes (such as
dark radiation, or dark light or dark photon, etc.) in the dark sector of universe. Professor Lisa Randall of
Harvard University, Professor Sean Carroll at the California Institute of Technology, and several other
scientists have already explored and proposed dark radiation, dark light and dark photon in the dark sector of
the universe. More supporting information is in Section 8 of my Web Page (3).

All the dark matters associated with Gravity Hills and Mystery Spots discussed on this Web Page (2) are
Type B dark matter with extreme high density.

2. Why the source of significant abnormal local gravity for these mysteries is NOT our familiar ordinary
matter, but is dark matter?

As soon as we realize that these two mysteries at these special locations of Gravity Hills and Mystery Spots
are real and are NOT due to illusion, an immediate and challenging question is “What is the source for such
significant abnormal local gravity?”

Some friends suggested that may be there is a large deposit of heavy metal ore under the location of a
Gravity Hill or a Mystery Spot and the gravity of such heavy metal ore is creating such gravity mysteries.
Following such suggestion, I did some estimation and calculations and found that the mass density of heavy
metal ore in the earth is too low by at least three order of magnitude and is NOT able to produce those
gravity mysteries on a Gravity Hill or a Mystery Spot.

Even though such heavy metal ore cannot produce the gravity mysteries observed on a Gravity Hill or a
Mystery Spot directly, such heavy metal ore does play an important role indirectly by providing a framework
of gravity anchor to attract dark matter into very high density cluster and stream that produces the gravity
mysteries on a Gravity Hill or a Mystery Spot. More details on such gravity anchor effect are described in
Section 5.6.

My 23-year research indicates that the source is NOT our familiar ordinary matter, but is very high density
dark matter. It involves the following logical steps and the necessary information to reach such profound
conclusion:

2.1. First Estimation of Physical Size of the Source of Significant Abnormal Local Gravity

The available information indicates that such gravity mysteries in Oregon Vortex, Mystery Spot and Cosmos
Mystery Area, etc. exist only in a very small area of about 150 feet (for Mystery Spot in Santa Cruz), 165
feet (for Oregon Vortex), to 300 feet (for Mystery Spot in Michigan). The typical length of many Gravity Hills
is also only a few hundred feet.

Such information indicates that the physical size of the core of the source of such significant abnormal local
gravity must be substantially less than 150 feet (half of the 300-ft circle) so that its gravity is significant only
inside such small areas and diminishes to negligible level beyond a few hundred feet from the compact sized
source.

2.2. Second Evidence of Small Scale Structure of Significant Abnormal Local Gravity

My simple experiment in the Mystery Spot in Santa Cruz on January 11, 2016 indicates that my body weight
at the two standing positions of the Shrink-and-Grow mystery near the entrance (i.e., the edge, the  
perimeter) of Mystery Spot area are different by 2.5 % (206 lb vs. 211 lb) as described in more details in my  
web page at:

http://
www.shltrip.com/Body_Weight_Measurement.html


The 2.5% difference in the downward (vertical) component of gravity on earth surface may looks small and
unimpressive to many people. But for people who pay some attention to geophysics, especially the science of
earth gravity, will realize that the 2.5% difference in earth gravity on earth surface is extraordinary and is a
big deal. For example, the summaries of the known facts about earth gravity on earth surface in the following
two references:

Wikipedia on Earth Gravity at:

https://
en.wikipedia.org/wiki/Gravity_of_Earth

and

"How precise is Earth’s gravity?" by Glen Thorncroft at:

http://
www.calpoly.edu/~gthorncr/ME302/documents/AccuracyofGravity.pdf

indicate that the variation in earth gravity across the earth surface should vary by no more than 0.7%.

Usually, the earth gravity on earth surface is quite stable, normal, and varies by less than 0.7% across earth
surface. Furthermore, the normal earth gravity vector is pointing vertically down into the center of the earth (i.
e., has no horizontal component of gravity.) This is the basic principle used by the bubble based carpenter's
level, plumb line and by the bubble based survey instruments to obtain the basic local horizontal reference
plan and the local vertical reference line for various precision land survey measurements.

However, the extraordinary variation of 2.5% of the vertical component of gravity at such a short distance of 2
feet in the very special location of Mystery Spot area indicates that the gravity in such special area is very
abnormal, has a fine scale structure that is very atypical of the earth gravity. As a contrast, the normal earth
gravity from the huge volume of the entire earth is usually very uniform over vary large area of many miles on
earth surface.

Such measured results in Mystery Spot in Santa Cruz indicate that the physical size of the core of the source
of such significant abnormal local gravity must be very small to be able to create a gravity field that can
change so much (2.5%) in 2 feet of short distance.

Again, the strength and the vector direction of normal earth gravity do not change significantly in such short
distance of 2 or 3 feet on earth surface. It takes a very small sized but powerful source of gravity to be able
to produce such strong abnormal local gravity such that the strength and the vector direction of the abnormal
gravity can change significantly in such short distance of 2 or 3 feet.

2.3. Third Evidence of Small Scale Structure of Significant Abnormal Local Gravity

The abnormal local gravity in a Mystery Spot area is usually strongest near and inside the Mystery House
which is usually near the center of such Mystery Spot area. When we get very close to or inside the Mystery
House, we feel a very strong horizontal gravity pull on our bodies. But when we take a few steps away from
the Mystery House, the strong horizontal pull on our bodies diminishes significantly. This is another indication
that the strong abnormal local gravity varies substantially over a short distance of a few feet.

2.4. Fourth Evidence of Small Scale Structure of Significant Abnormal Local Gravity

The demonstration of free standing broom in Mystery Spot area works only in a limited area inside the
Mystery House as described in more detail on my web page at:

http://
www.shltrip.com/Free_Standing_Broom.html

Such demonstration will not work outside of the Mystery House at other arbitrary locations in the Mystery
Spot area. This is an indication that the core of the source of significant abnormal gravity is very small in size
in a limited area near or inside the Mystery House.


2.5. Fifth Evidence of Small Scale Structure of Significant Abnormal Local Gravity

Several researchers have done clock speed measurements inside and outside of several Mystery Spot
areas. Their measurement results indicate that clock speed inside the Mystery Spot area is different from
those outside. Furthermore, the measured clock speed inside the Mystery Spot area is NOT uniform, but
varies with location inside the Mystery Spot area. This is another indication that the significant abnormal local
gravity is NOT uniform, but varies with location inside or near the Mystery Spot area.

2.6. Important Finding on Physical Size

The five evidences listed above indicate that the physical size of the core of the source of the abnormal local
gravity in such Mystery Spots must be very small in size in the order of feet or less to be able to produce
such small scale structure in the gravity vector originated from such compact sized source.

Important Finding 1: Estimated physical size of the core of the source of significant abnormal local gravity is in
the order of feet or less.

2.7. Estimation of Mass Density in Compact Source of Significant Abnormal Local Gravity

As explained in Sections 3.1 and 3.2 in my companion Web Page (1), the strength of the significant abnormal
local gravity along the slope of a Gravity Hill must be a few percent or more of normal earth gravity on earth
surface to be able to pull vehicles, in neutral gear and brake released, to roll uphill with an inclination angle of
a few degrees on most Gravity Hills. This means the very small and compact source of the significant
abnormal local gravity must have extremely high mass density in order to have enough total mass in that small
and compact volume to produce such strong abnormal local gravity that is at least a few percent of the
normal earth gravity on earth surface.

Such information enables me to do back-of-envelope-calculations to estimate that the small and compact core
of the source of the significant abnormal local gravity must have extreme high mass density at least 1,000
times greater than that of average ordinary matter on earth surface in order to have enough strength of
abnormal local gravity to produce the Gravity Hill mystery.

However our familiar ordinary matter on earth surface cannot provide such extreme high mass density.
Therefore, the compact source of such significant abnormal local gravity in all these special locations is NOT
our familiar ordinary matter, but is some unknown, unfamiliar and very strange matter(s) to have such
extreme mass density.

Another way to illustrate this point is the following. We all have experience of driving a car on an uphill road
toward a huge mountain. But on most situations (except on a Gravity Hill), our car cannot roll uphill on its own
no matter how big the mountain is and no matter what kind of ordinary matter is in the mountain. The gravity
from the huge mountain is never strong enough to pull a car to roll uphill on its own. We always have to press
on the gasoline pedal for the engine to push the car to go uphill. The mass density of ordinary matter in the
mountain is never dense enough to create the Gravity Hill Mystery. It requires the extremely high mass
density of unknown, unfamiliar and very strange matter in a compact small cluster to be able to create the
Gravity Hill Mystery.

2.7.1. Important Finding on Extreme High Mass Density of the Source of Significant Abnormal Local Gravity

Important Finding 2: Estimated mass density of compact cluster of the core of the strange source of
significant abnormal local gravity is at least 1,000 times greater than that of average ordinary matter on or
near earth surface.

This is an initial estimation of the lower bound of the mass density of the compact core of the source of
significant abnormal local gravity.  The actual mass density may be much higher than this estimated lower
bound of 1,000 times greater than that of average ordinary matter on earth surface. More research is needed
to improve this estimation if we can know the physical size of the compact core more accurately in the future.

2.8. Is the Source Underground, On the Ground or Above Ground?

On hundreds of Gravity Hills all over the world, the source of such significant abnormal local gravity must be
on or above the earth surface to be able to pull the vehicles (in neutral gear and brake released) to roll uphill.

In other words, if the source were buried deep underground, its abnormal local gravity would pull the vehicles
down and would increase the weight of the vehicle, but would NOT pull the vehicle to roll uphill.

When visitors are near the Mystery House in a Mystery Spot area, all visitors feel a very strong horizontal pull
on their bodies. Such strong horizontal pull also indicates that the source of such strong pull is on or above
ground, not deep underground to increase their body weight.


2.9. Nobody has ever seen them or touched them

John Lister, a Scottish physicist, geologist and mining engineer, spent about 30 years from early 1930s to
1959 performing thousands of experiments and measurements to investigate the strange gravity phenomena
at Oregon Vortex in southern Oregon, USA. This strange compact source of abnormal local gravity should be
inside the 165-ft circle of Oregon Vortex and should be on the ground or above the ground. If the strange
source of such significant abnormal local gravity with such extreme high mass density at Oregon Vortex were
our familiar ordinary matter, John Lister would have detected and found it in his 30 years of intensive
investigations in Oregon Vortex.

After John Lister passed away in 1959, some other researchers have also done many years of
measurements and tests in Oregon Vortex. Furthermore, Oregon Vortex is in the historical gold rush area
with many gold miners working in that area. Those gold miners felt the gravity mysteries of Oregon Vortex,
but nobody had seen, or detected or touched such strange matter with such extreme high mass density.

Furthermore, thousands of visitors have been visiting Mystery Spots every year for many years since 1930.
The owner and many tour guides have also been working in these Mystery Spots for many years. But nobody
have seen or touched such strange matter in Oregon Vortex or in any other Mystery Spots.

Similarly, so far and for so many years, nobody has seen or detected or touched such strange matter with
such extreme high mass density at hundreds of known Gravity Hills all over the world.

3. Summary of Characteristics of Strange Source of Significant Abnormal Local Gravity at Gravity Hills and
Mystery Spots

3.A.        We cannot see it,
3.B.        We cannot touch it,
3.C.        But we can feel and observe the effects of its significant gravity,
3.D.        Its mass density in the compact core at a Gravity Hill (or a Mystery Spot) is at least 1,000 times
greater than that of average ordinary matter on earth surface.

This set of characteristics is a strong hint of very high density Type B dark matters on earth.

Aside from Type B dark matter, I cannot think of any other matter on earth that can fit such set of
characteristics 3.A, 3.B, 3.C, and 3.D listed above.

Such set of characteristics naturally and logically lead into:

3.2. Hypothesis 2 on Compact Core of Dark Matter with Extreme High Mass Density

Hypothesis 2 is that such strange source of significant abnormal local gravity in these special locations of
Gravity Hills and Mystery Spots is some kind of very small and compact core of Type B Dark Matter with
extreme high mass density.

However, Hypothesis 2 immediately provokes two challenging questions:

Question 3.2.1: Where does this compact core of Type B dark matter with extreme high mass density come
from?, and

Question 3.2.2: By definition, dark matter rarely interacts with our familiar ordinary matter directly by any
force except by gravity. Then, what is supporting and holding the compact core of high density Type B dark
matter at a special location of a Gravity Hill (or a Mystery Spot) steadily? (We know that our familiar ordinary
matter cannot do that directly.)

The answers from my 23 year research to these two challenging questions are in Sections 5

4. Dark Matter

A good summary of currently available information on dark matter is at the following Wikipedia website:

http://
en.wikipedia.org/wiki/Dark_matter  

However, our collective knowledge on dark matter is still very limited.  We know that we cannot see it, cannot
touch it, but we can feel and observe the effects of the gravity from dark matter.

5. Hypothesis 3 on Type B Dark Matter Trapped and Oscillating in Earth Gravity Well

The observed behavior of strange gravity phenomena from Gravity Hills and Mystery Spots, both fortunately
and unfortunately, leads me into the new frontier of modern science involving the mysterious dark matters.

It is fortunate in that these Mystery Spots and Gravity Hills lead me into doing research on the very exciting
new frontier of modern science.

But it is unfortunate in that in spite of the great effort of many scientists all over the world working on dark
matter for many years, we collectively still knows very little about the mysterious dark matter. I am venturing
into unchartered territories with many very challenging unknowns. Doing research on such forefront science is
extremely difficult and challenging, especially dealing with Type B high density dark matter, in addition to more
familiar low density Type A dark matter.

Many scientists have been investigating dark matter using astronomy observations with distance scale of
many light years. I have been investigating dark matter on earth for 23 years with distance scale in the order
of feet based on Gravity Hills and Mystery Spots.

With more in-depth thinking on these available observed behavior of strange gravity mysteries on Gravity Hills
and in Mystery Spots for many years, I began to realize in June 2014 that there is a way for Type B high
density dark matters in our earth to be the steady source for the significant abnormal local gravity on those
Gravity Hills and in those known Mystery Spots. This hypothesis on dark matter based Theory is described in
more details in the following sections.

5.1. Dark Matter Oscillating inside the Gravity Well of Earth and through the Center of Earth

The known characteristics of dark matter are that dark matters permeate the space around us, flying through
our familiar ordinary matters. Dark matter does not absorb, emit or reflect light or any other electromagnetic
radiation. Dark matter interacts with ordinary matter through gravity, but only rarely interacts with ordinary
matter directly through any other forces.

Such characteristics mean that our familiar ordinary matters on earth cannot support and hold the cluster of
high density Type B dark matter directly for the cluster to stay at the special positions of a Gravity Hills (or a  
Mystery Spot area) steadily. The cluster of dark matter will be sucked into the center of earth by earth
gravity, and it will over-shoot to keep going to the opposite side of earth surface while being slowed down in
its speed by earth gravity. I shall call that location on the opposite side of earth surface as the conjugate point
of the original location of a Gravity Hill (or a Mystery Spot).

After the dark matter cluster reaches the conjugate point on the opposite side of earth surface and stops
there, the earth gravity will pull cluster back toward the center of earth again. Then the cluster will over-shoot
to keep going back to the original location of the Gravity Hill (or the Mystery Spot area) on earth surface.

In other words, in my Hypothesis 3, the Type B high density dark matter particles are trapped in the gravity
well of the earth and are oscillating through earth center between those two opposite (conjugate) positions on
earth surface.

5.2. It is not a Solid and Rigid Cluster

However, to be the steady source of Gravity Hill Mystery at a known location of a Gravity Hill (or Shrink-and-
Grow Mystery in a Mystery Spot area), the oscillating dark matter particles cannot be all lumped together in
a rigid and solid compact cluster because when the solid compact cluster is traveling into the center of earth,
the gravity of the compact cluster will become negligible at the original location of a Gravity Hill (or a Mystery
Spot area) on earth surface.

Therefore, the compact cluster of high density Type B dark matters must be supported by two narrow vertical
streams of very high density dark matter. A downward stream is being sucked from the compact cluster into
the center of earth and the second upward stream is returning from opposite side (conjugate point) of earth
through center of earth back to the original location of the Gravity Hill (or the Mystery Spot area). This means
the composition of the compact cluster of Type B dark matter with very high mass density is constantly
changing, a downward stream of dark matter is just leaving being sucked downward to the center of earth
while the other upcoming stream is returning from the center of the earth back into the compact cluster of
dark matter with very high mass density.

In this way, there appears to have a compact cluster of Type B dark matter with very high mass density at
the location of a Gravity Hill (or a Mystery Spot area) steadily and supported by two vertical streams of Type
B very high density dark matter as part of the earth.

5.2.1. Fountain of Dark Matter

The cluster of Type B dark matter supported by an upward narrow stream of Type B high density dark matter
in a Mystery Spot area (or a Gravity Hill) is almost like a water fountain bubbling, thrashing and splashing in
the Mystery Spot area except that (a) we cannot see and cannot touch that fountain of high density dark
matter and (b) the mass density of dark matter of the narrow stream shooting upward at the central column
of the fountain is at least 1,000 times greater than that of our familiar ordinary water.

Since we cannot see dark matter, I use Picture 1 in the following of the upper part of a picture of a water
fountain to help us visualize the fountain of Type B dark matter in a Mystery Spot area (or a Gravity Hill). In
the center of the fountain is a narrow stream of Type B high density dark matter shooting up from the center
of the earth. As this narrow stream is shooting up, the earth gravity slow down its upward speed until it stop
at the top. Then the dark matter particles at the top spread out and splash down like a water fountain in
Picture 1.

The core of the fountain of dark matter is the narrow stream of Type B high density dark matter at the central
column shooting up from the center of earth towards the top of the fountain. On the ground surface, the
location of this central column (or stream) of Type B high density dark matter is the center of the Mystery
Spot area. The cross section width of the narrow stream of Type B high density dark matter is estimated in
Section 2.6 to be in the order of feet. Usually the Mystery House is near this center of Mystery Spot area.

The intersection of the fountain of dark matter with the ground surface is a circular area. This circle is known
as the circle of demarcation or line of demarcation. The diameter of this circular area may be in the order of
100 feet. With many years of experience as a tour guide in Mystery Spot areas, Mr. Nick Nelson told me that
if he takes just one step across this line of demarcation into the Mystery Spot area, his height shrinks by
couple inches immediately. Similarly, if he takes just one step across this line of demarcation to outside of
Mystery Spot area, his height grows by couple inches immediately. The two standing positions of a
demonstration platform of the Shrink-and-Grow Mystery are often on the opposite sides of this line of
demarcation.
5.2.2. Another Fountain of Dark Matter at the Conjugate Point of Opposite Side of Earth

After the dark matter particles in the fountain falls below the ground surface, the earth gravity will suck them
downward toward the center of earth. But Type B dark matter has special characteristics to shrink the space
nearby and to clump together into very high density as described in Web Pages (3) and (6). Therefore, as
the Type B dark matter particles are falling down toward the center of earth, they will clump together into a
narrow stream of very high density Type B dark matter.

When this narrow stream of dark matter reaches the center of earth, the narrow stream of dark matter with
over shoot and keep going to the conjugate point on the opposite side of the earth. At the conjugate point,
the earth gravity will slow down the narrow stream of dark matter to stop and to form another fountain of
dark matter at the conjugate point.

In this way, the Type B dark matter particles are trapped in earth gravity well in the form of two narrow and
long streams going in opposite directions to oscillate back and forth in earth gravity well. At each end of the
long narrow stream is a fountain of dark matter described above.


5.3. Where do these Type B dark matter particles oscillating in earth gravity well come from?

Since we, the whole world, still do not know what dark matter is and still know very little about the
characteristics of dark matter, we, the whole world, are learning by observing the results of all the on-going
dark matter experiments and observing the effects of dark matter on ordinary matters. In this sense, our
answer to this question 5.3. is preliminary and speculative at this early stage.

As Section 1.1. indicates that there are two types of dark matter. The Type B dark matter can clump
together into much higher density. With such understanding, there are at least two possible ways for Type B
dark matter particles to be trapped and oscillating in earth gravity well:

5.3.1. Got In at the Formation Stage of Earth

According to Hypothesis 1 in Section 1.1, Type B dark matter can clump together into high density compact
nuggets, some of such nuggets of Type B high density dark matter might have formed in the space many
billions years ago. When the ordinary matters are clumping together to form the earth about 4 and half billion
years ago, some of such high density nuggets of Type B dark matter might be also involved in such process
and be parts of the earth right from the beginning of the earth. It might be possible that such high density
compact nugget of type B dark matter might have served as the seed to pull other ordinary matters to clump
together to form the earth.

5.3.2. Got in at Later Stage of Earth History

The available dark matter information indicates that the probability of a collision between a dark matter
particle and a piece of our familiar ordinary matter is very low, but not zero. When a dark matter particle in
galaxy dark matter halo collides with our familiar ordinary matter on the earth, the dark matter particle loses
substantial amount of energy and momentum in such collision. After losing such energy and momentum, the
dark matter particle with lower energy may be captured by earth gravity, trapped and oscillating in earth
gravity well.

Even though such collision probability is very low, the accumulated number of dark matter particles trapped
and oscillating in earth gravity well may be substantial for two important reasons: (1) the huge number of
molecules of ordinary matter in the huge volume of the entire earth are involved in such collision with and  
capturing of dark matter particles and (2) this process has been going on for more than 4 billion years to
accumulate the captured dark matter particles in the earth gravity well.

By losing some kinetic energy in the collisions with ordinary matter in the earth, the average "temperature" of
the dark matter particles trapped and oscillating in earth gravity well is lower than that of dark matter
particles moving randomly in galaxy dark matter halo.

5.4. Clumping of Type B Dark Matter Particles Trapped in Earth Gravity Well

According to Hypothesis 1, Type B dark matter can clump together into much higher density because it can
shed more energy and cool down further through a dissipative process involving yet unknown interaction
processes in the dark sector of universe (such as dark radiation or dark light or dark photon, etc.). Professor
Lisa Randall of Harvard University, Professor Sean Carroll at the California Institute of Technology, and
several other scientists have already explored and proposed dark radiation, dark light and dark photon in the
dark sector of the universe.

Furthermore, recent experimental results from Hungary and from Large Hadron Collider (LHC) at the
European Organisation for Nuclear Research (CERN), on the French-Swiss border provide preliminary hints
on the existence of such previously unknown force carrier boson that may interact with dark matter. A little bit
more details on such experimental results are on Section 7 on my Web Page (3) at:

Web Page (3): http://
www.shltrip.com/Two_Populations.html

The observed Shrink-and-Grow Mystery on several Mystery Spots is also pointing to the existence of high
concentration of Type B dark matter that requires such dark interaction process for Type B dark matter to
clump together into very high density nugget.

Such yet unknown dark interaction processes and clumping of Type B dark matter into very high density are
all part of the great mysteries of dark matter and dark sector of universe that requires more research in the
future.

5.5. Hypothesis 4 - Gravity Anchor for Dark Matter Particles Trapped in Earth Gravity Well

Even with the gravity well of the earth trapping the dark matter particles, the dark matter particles still have
lots of freedom to oscillate randomly in the earth gravity well. Knowing that the earth is rotating on its axis
and also orbiting the sun, a key question is

“How the fountain of Type B dark matter and its associated long narrow streams of Type B dark matter are
anchored to the location of a Gravity Hill (or a Mystery Spot) on the earth surface steadily?”

My preliminary thinking on this important issue is the following:

The distribution of earth ordinary matter in the earth crust is not uniform and not homogeneous. There are
large deposits of heavy metal ores such as iron ore, copper ore, gold vein, etc. at various places. These
large deposits of heavy metal ores have stronger gravity relative to those of the average earth crust material
(such as rocks) and will attract the freely oscillating dark matters that are trapped in earth gravity well.

Furthermore, Type B dark matter particles can clump into higher density nuggets. Therefore, many Type B
dark matter nuggets, trapped and oscillating in earth gravity well, will clump together and oscillate through
the area of a large deposit of heavy metal ore.

Therefore, a large deposit of heavy metal ore in the earth crust becomes a gravity anchor to anchor the long
and dense streams of oscillating dark matters to the location of the large deposit of heavy metal ore. The
two ends of such anchored and oscillating long streams of very high density dark matters reaching the earth
surface are the fountain of Type B high density dark matter that show the effects of their significant abnormal
local gravity as the Gravity Hill Mystery that we observe at hundreds of known Gravity Hills or the Shrink-and-
Grow Mystery in several known Mystery Spots on earth surface.

Since the large deposit of heavy metal ore in earth crust is the ordinary matters of earth, is part of the earth,
and is rotating with the earth along earth axis and moving with earth to orbit the sun, the large deposit of
heavy metal ore is serving as the gravity anchor and is dragging the long streams of oscillating Type B dark
matter particles and the fountains of Type B dark matter at both ends to rotate in sync with earth rotation
and to move with earth to orbit the sun. Therefore, the location of the fountain of Type B high density dark
matters can be reasonably stable at the location of a Gravity Hill (or a Mystery Spot) on earth surface for
many years because of the gravity anchor provided by the large deposit of heavy metal ore.

5.6. Some Supporting Information on Gravity Anchor for Dark Matters Oscillating in Earth Gravity Well

Oregon Vortex is in the historical gold rush area and its address is at Gold Hill in southern Oregon. The
House of Mystery in Oregon Vortex was originally a gold assay office built by the Old Grey Eagle Mining
Company in the late 1890s. Assay offices are institutions set up to assay (test the purity of) precious metals.

The Mystery Spot in North Carolina is known as Mystery Hill, and there are
300 gold mines and gold
prospect locations in North Carolina. North Carolina has the First Documented Discovery of Gold in the
United States.

The Mystery Spot in South Dakota is known as Cosmos Mystery Area, and the Big Thunder Gold Mine is
within couple miles from Cosmos Mystery Area.

Some measurements of magnetic field in some Mystery Spots in south and north California, USA (including
Mystery Spot near Santa Cruz) indicate that the strength of magnetic field inside the Mystery Spots is higher
by several percents relative to that of normal earth magnetic field outside of the Mystery Spots. These are
good indication of existence of higher concentration of iron in the grounds under these Mystery Spots in
California to serve as the gravity anchor for dark matters.

However, the strength of the abnormal magnetic field in these Mystery Spots is higher than the normal value
by only a few percent. Such abnormal magnetic field is not strong enough to pull the vehicles in neutral gear
to roll up the Gravity Hills. It is still the significant abnormal local gravity of the compact nugget of dark matter
with extreme high mass density that is causing two observed strange gravity mysteries.

5.7. Highly Non-Uniform Distribution of Dark Matter Particles Trapped in Earth Gravity Well

The dark matter particles trapped in earth gravity well are not oscillating totally freely and randomly in earth
gravity well. The Type B dark matter particles can clump together into much higher density because it can
shed more energy and cool down further through dark radiation, dark light and dark photon or other yet
unknown processes in the dark sector of universe. The existence of hundreds of known Gravity Hills all over
the world and several known Mystery Spots indicates that there are hundreds of such narrow streams of
very high density Type B dark matter oscillating in earth gravity well. Additional considerations in Section 5.9
indicate that there may be thousands of such narrow streams of high density dark matter oscillating in earth
gravity well.

In other words, the distribution of Type B dark matter particles trapped in earth gravity well is not uniform,
but is highly concentrated in those thousands of narrow streams of high density dark matter oscillating in
earth gravity well. This is important to the ongoing global effort by many teams of scientists to try to detect
dark matter directly in many deep underground laboratories at various locations in the world. With such highly
non-uniform distribution of Type B dark matter particle trapped in earth gravity well, one cannot expect all
these deep underground laboratories to have the same probability of detecting Type B high density dark
matter. It all depends on whether the dark matter detector intercepts one of such narrow streams of very
high density Type B dark matter or not.

5.8. One More Twist in this Theory Based on Observed Dynamic Behavior of Gravity Mysteries

The fountain of dark matter supported by the two streams described in Sections 5.1 to 5.6 is shaky and
fragile such that the abnormal local gravity originating from such shaky source is not absolutely stable, but
has some dynamic time variations.

Several kinds of observed dynamic time variations of gravity mysteries at Oregon Vortex reported on Internet
are collected in my Web Page (5) at:

Web Page (5): http://
www.shltrip.com/Dynamics_of_Gravity-Mysteries.html

5.8.1. Slowly Moving Location of the Fountain of Type B Dark Matter

The observed strange dynamic behavior in Section 2 on Web Page (5) above implies that the location of the
fountain of Type B dark matter with very high mass density is not absolutely fixed but is moving slowly on a
tract on earth surface about several feet in length. The fountain of Type B dark matter with very high mass
density on earth surface appears to be oscillating slowly with an oscillation amplitude (distance) in the order
of several feet with the slow oscillation period of about several times per day.

A possible reason for such slowly moving or oscillating location of the fountain of dark matter on earth
surface is that the gravity anchor for the location of the stream of oscillating dark matters and the location of
fountain of dark matter is not a rigid anchor, but is an elastic gravity anchor. The influence of the gravities
from the moon and the sun can stretch the elastic gravity anchor so that the location of the oscillating stream
of dark matters and the location of fountain of dark matter can deviate slowly from their equilibrium positions.
In other words, the effects of gravities from the moon and the sun can cause slow diurnal and seasonal
movements of the location of the long stream of dark matters and of the fountain of dark matters on earth
surface.

However, the observed oscillation frequency of several times per day of the location of fountain of dark
matter indicates that there may be some other effects in addition to the effects from moon and sun. The
length of the long stream of dark matters in the earth is about 7,918 miles (i.e., the diameter of the earth).
May be the natural resonance frequency of such a long stream of dark matters vibrating away from its  
equilibrium position in the elastic gravity anchor is several times per day. This is a subject for further
investigation in the future.

Such slow time variation and slow oscillation of the location of fountain of high density Type B dark matters
will be important to understand the seasonal modulation in the detected dark matter signal in the deep
underground laboratories in Italy and in Minnesota as described in Appendix D.

Some more slow time variations of gravity mysteries in Mystery Spots are described in Appendix C.

5.9. Thousands of Narrow Streams of Type B High Density Dark Matter Oscillating in Earth Gravity Well

The hundreds of known locations of Gravity Hills are all on the existing paved roads where vehicles (with
transmission in neutral gear and brake released) roll uphill on the strange slopes on their own and startled the
drivers. But very large areas of the earth surface are still wilderness, heavy forests, farm fields, oceans,
bays, lakes, rivers, wetlands, deserts or golf courses where there are no paved roads. If there are Gravity
Hill effects with abnormal local gravity in such areas, we probably still do not know about them because there
are no paved roads for the vehicles to roll uphill in such areas.

Furthermore, if the directions of the paved roadway and their slopes are not aligned with the direction of the  
abnormal horizontal local gravity force, such abnormal horizontal local gravity force is not strong enough to
pull vehicles to move sideway across the road surface. Then nobody will notice the possible existence of
abnormal horizontal local gravity force in such locations.

Even if the direction of the paved road and its slope are aligned with the direction of the abnormal horizontal
local gravity force, if such abnormal local gravity is in the direction of pulling vehicle to roll downhill on such
road, then we will not recognize it as a Gravity Hill with abnormal local gravity because the vehicle is rolling
downhill as expected.

Some of my friends are experienced golf players. These friends told me that sometime golf players cannot
rely on their visual perception of the slope of a golf course to predict accurately which way the golf ball will
roll. Sometime the golf balls just roll in a very strange and unexpected way. It may be possible that the
Gravity Hill effect may exist on some parts of some golf courses, but people do not recognize it as Gravity
Hill effect because there is no paved road there for vehicles in neutral gear and brake released to roll uphill.

In many developing countries, as more new roads are constructed and paved, more Gravity Hills are being
discovered on such paved new roads. Therefore, the total number of locations on the earth surface with such
Gravity Hill Mystery and Shrink-and-Grow Mystery may be much more than those known hundreds of
locations.

Therefore, there may be thousands of narrow streams of high density dark matter oscillating in earth gravity
well,  but so far we have experienced and know only a fraction of them in the form of hundreds of known
Gravity Hills and several known Mystery Spots.


6. Space Shrinking by Dark Matter as the Source of Dark Energy revealed from Shrink-and-Grow Mystery

By visiting several Mystery Spot areas, visiting two Mystery Spot areas multiple times and doing extensive
research on the Shrink-and-Grow Mystery in these Mystery Spot areas for more than 23 years, I discover
that dark matter can shrink space in its vicinity. This ground breaking discovery is important because:

1. It provides a scientific explanation for the Shrink-and-Grow Mystery.
2. Spacetime shrinking by dark matter is the second method for dark matter to interact with ordinary matter,
in addition to the well known first method of gravity, and
3. It leads into the next ground breaking discovery that dark energy comes from the highly shrunk or highly
compressed spacetime by the huge amount of dark matter in extreme high density state during the early
stage of universe.

This section 6 has been expanded and becomes my new Web Page (6) at:

Web Page (6): http://
www.shltrip.com/Space_Shrinking_Capability_of_Dark_Matter.html


7. Application of This Theory to Dark Matter Detection in Deep Underground Laboratories

Twelve or more deep underground laboratories have been set up in various locations of the world and
running for many years in a race to try to detect dark matter. However, ten or more deep underground
laboratories keep on coming up empty handed. But the deep underground laboratory in Gran Sasso mountain
in Italy claims that they have detected dark matter with a signature of annual modulation (seasonal variation)
in the detected signal. Another deep underground laboratory in Soudan, Minnesota, USA has also detected
similar signal with a similar signature of annual modulation.

It has been a serious dilemma in science community for many years because the claimed detections of dark
matter in Italy and in Minnesota, USA are NOT repeatable in ten or more deep underground laboratories in
other parts of the world. Many scientists question the validity of the claim that dark matters have been
detected in Italy and Minnesota. Many scientists think what the laboratories in Italy and Minnesota, USA have
detected are false signals due to problems in detection systems.

On the other hand, my 23-year research on gravity mysteries on Gravity Hills and Mystery Spots on earth
enables me to bring in an out-of-box thinking to resolve this serious dilemma. My different background and
experience enable me to show that:

(1) My theory provides strong support for the successful direct detection of Type B high density dark matter
in the deep underground laboratory in Gran Sasso mountain in Italy and in deep underground laboratory in
Soudan, Minnesota, USA, and

(2) None of the twelve or more deep underground laboratories have detected Type A low density dark
matter because Type A dark matter particles may be super-heavy dark matter particles which may be much
heavier than the popular assumption of WIMP by many orders of magnitude.

More detailed explanations and supporting evidences are on my Web Page (3) at:

Web Page (3): http://
www.shltrip.com/Two_Populations.html


8. Concluding Remark

In my 23-year research, I have been collecting available information on Gravity Hill Mystery on hundreds of
known Gravity Hills all over the world and on Shrink-and-Grow Mystery in several known Mystery Spots and
applying my analysis skill to guide my formulation and development of a logical and scientific theory for these
mysteries on Gravity Hill and in Mystery Spot areas on earth. The collected information on these observed
mysteries on earth provide hints and tips on characteristics of dark matter and lead into the theory of very
high concentration of Type B dark matter at these special locations as the source responsible for the
observed mysteries on earth.

Through e-mail correspondence, Mr. Nick Nelson has been very helpful in providing valuable inputs on various
mysteries in Mystery Spot areas based on his many years of experience as a tour guide and a researcher on
Mystery Spot areas.

The observed Shrink-and-Grow Mystery and the slow movements of scenery in Mystery Spot area provide
important hint that the high concentration of Type B dark matter shrinks space in its vicinity. The important
implications of this discovery of space shrinking characteristics of dark matter to dark energy are described
in my Web Page (6) at:

Web Page (6): http://
www.shltrip.com/Space_Shrinking_Capability_of_Dark_Matter.html

The preliminary theory guided by these hints and tips from the observed mysteries on earth requires
formulation of five (5) hypotheses which are reflection of how little our collective knowledge knows about
dark matter. These five hypotheses are all parts of the great mysteries of dark matter that require more
research in the future.

An application of this theory to the direct detection of dark matter in deep underground laboratories is
described in my Web Page (3) at:

Web Page (3): http://
www.shltrip.com/Two_Populations.html

This theory also indicates that these special locations of Gravity Hills and Mystery Spot areas on earth
provide golden opportunities for close-up hand-on experiments to investigate dark matter, especially very
high concentration of Type B dark matter and its associated dark interaction processes in dark sector of
universe.

***********************************************************

Appendix A: A Signature of Mystery Spot Area

The available information on Internet on Mystery Spot areas indicates that if one blows smoke into the air or
throws a handful of confetti (many small pieces of colorful paper) up into the air in the area of a Mystery
Spot, those confetti do not just fall straight down. Instead, those confetti or smoke will spiral in the air and
converge into a "vortex". It is said that this is how Oregon Vortex got “Vortex” in its name. Some supporting
information on rotating vortex are in Section 3.2. on my web page at:

http://
www.shltrip.com/Effect_of_Mystery_Spot_on_Human_Being.html

But I have not seen demonstration of this special mystery personally. I do not know how close to the “Vortex”
must be for this behavior of smoke and confetti to take place. I hope that some researchers can try it to see
if it can be verified.

If this special behavior can be verified, it may be useful to find more precise location of the core of high
density dark matter or of the narrow stream of high density dark matter in a large area (of several hundred
feet) of significant abnormal local gravity. In other words, this special behavior may be useful to find the
optimal location for the dark matter detector to intercept the narrow stream of Type B high density dark
matter in a deep underground laboratory designed for direct detection of dark matter.

Appendix C - Non-Uniform Streams of Dark Matter

The booklet of John Lister indicates that the size of the area of Oregon Vortex that exhibits gravity mysteries
is not constant, but is expanding and contracting slightly in an oscillation with an oscillation frequency of
several times per day. This seems to imply that the two long streams of dark matter running between the
two conjugate points on earth are not uniform in the density of dark matter or the cross section width is not
constant along the long streams. The density of dark matter or the cross section width in some sections of
the streams may be larger than those at other sections of the streams. So, when a denser section or a
larger section of the stream arrives at the Oregon Vortex, the size of Oregon Vortex appears to be slightly
larger. Similarly, when the less dense section or the smaller section of the stream arrives to replace the
denser section or the larger section of the stream, the size of the Oregon Vortex appears to contract to a
smaller size.

The time variations of the fountain of dark matters described in Section 5.8 are important contributors to
many slow time variations of observed mysteries at Oregon Vortex.

For example, one of such observed multiple mysteries in Oregon Vortex in that a person's height may change
slowly even if the person is standing still at a given location in the Mystery Spot area without moving to other
location.


*************************************
Appendix D: My Proposal to Validate Dark Matter Detection in Deep Underground Experiments

D.1. A Serious Dilemma in Direct Detection of Dark Matters

For more than 17 years now, many scientists equipped with highly advanced experiment systems and
substantial research funding have been trying to detect dark matter directly. Twelve or more deep
underground experiments with dark matter detectors have been running for many years at several different
locations all over the world to try to detect the illusive dark matter directly.

News articles on such deep underground experiments for direct detection of dark matter can be seen at the
following sample websites:

Website DA - “Race is on to detect dark matter” at:
http://
usatoday30.usatoday.com/tech/science/2007-08-12-1941231126_x.htm

Website DB - The Wikipedia website on Dark Matter at:
http://
en.wikipedia.org/wiki/Dark_matter#Direct_detection_experiments

Website DC - “Dark matter and muons are ruled out as DAMA signal source” at:
<http://
physicsworld.com/cws/article/news/2015/apr/09/dark-matter-and-muons-are-ruled-out-as-dama-
signal-source>

Website DD – “The mystery of dark matter “ at:
http://
www.interactions.org/cms/?pid=1034004

According to Website DC, starting in 1998, the dark matter detection experiment – nestled deep
underground at the Gran Sasso National Laboratory in Italy – has reported an annual oscillation in the
detected signal from its dark-matter detector.

Some physicists believe that this annual modulation is a signature of the first direct detection of dark matter
and is believed to be a result of the Earth moving throughout the galaxy's halo of dark matter. They believe
that as the Earth orbits the Sun, the velocity of the detector relative to the dark matter halo will vary by a
small amount depending on the time of year. Further data collected by the collaboration over the past 17
years has given the measurement a statistical significance at 9.3σ – well beyond the 5σ that usually signifies
a discovery in particle physics.

According to the two news articles entitled “CoGeNT gives further backing to annual dark-matter variation” at
the following website:

Website DE - <
http://physicsworld.com/cws/article/news/2014/jan/20/cogent-gives-further-backing-to-annual-
dark-matter-variation>

and “Search for An Annual Modulation in Three Years of CoGeNT Dark Matter Detector Data” at:

Website DF - http://
arxiv.org/pdf/1401.3295v1.pdf

the results from the dark-matter detection experiment in Minnesota, USA also show the similar annual
modulation in the detected signal.

But many scientists remain skeptical, because no other deep underground dark-matter experiments across
the globe have detected a similar effect, calling the claim of the first direct detection of dark matter into
question. Other experiment sites keep on coming up empty handed. Some people even consider the
detected signal in Gran Sasso National Laboratory in Italy may be false signal due to problems in the
experiment system.

D.2. My Proposal to Validate Dark Matter Detection

D.2.1. Hypothesis D1 for the Dilemma in Detected Dark Matter Signal

My Hypothesis D1 for the two reasons that the underground experiments in Italy and in Minnesota, USA have
detected dark matter with its annual oscillation but other ten or more experiment sites have not detected the
similar signal are that

Reason (1): the experiment sites in Italy and in Minnesota, USA are lucky to be in the special locations that
intercept one of thousands of long and narrow streams of very high density Type B dark matter oscillating in
the earth gravity well as described in Section 5, and

Reason (2):  the popular assumption of WIMP as the candidate for dark matter may be wrong. The Type A
dark matter particle may be super-heavy particle which is heavier than WIMP by several orders of
magnitude. This means the density of Type A dark matter in galaxy dark matter halo is much lower than that
of assumed WIMP model by many orders of magnitude. Therefore, none of the twelve or more deep
underground laboratories have detected Type A dark matter with only a few years of experiments. It may
take thousands of years or longer of experiment in order to detect Type A super-heavy and very low density
dark matter particles.

The density of Type B dark matter in the long andnarrow streams described in Section 5 is much higher than
that of Type A low density dark matter in the dark matter halo around our Milky Way galaxy such that the
probability of dark matter detection is much higher if the dark matter detector is lucky to be in the special
location intercepting one of thousands of narrow streams of very high density Type B dark matters oscillating
in the earth gravity well.

In other words, what have been detected in Italy and in Minnesota, USA are Type B dark matter in the
oscillating long and narrow stream of very high density dark matter trapped in the earth gravity well and are
not the low density Type A dark matters freely floating in the dark matter halo of our Milky Way galaxy.

For example, the deep underground laboratory in Minnesota, USA is in the Soudan Mine which is an idled
iron mine and is known as Minnesota's oldest, deepest, and richest iron mine. It may be possible that the iron
ore under the ground here has been serving as the gravity anchor to anchor the narrow stream of very high
density Type B dark matter at this location.

D.2.2. My Model for Annual Modulation in Detected Dark Matter Signal

The experiments in Italy and in Minnesota, USA can see the annual modulation in the detected dark matter
signal because of the gravity from the sun. The earth’s orbit around the sun is not circular, but is elliptical.
The distance between the earth and the sun varies with the season. The gravity anchor to anchor the long
and narrow stream of oscillating dark matters in earth is elastic as described in Section 5.5. With such elastic
gravity anchor, the gravity from the sun can move the position of the narrow stream of the oscillating very
high density dark matter slightly depending on the season.

The cross section size of these long streams of oscillating high density dark matter in earth gravity well is
very small in the order of feet as described in Important Finding 1 in Section 2.6.

Therefore, the solar induced movement in the position of such narrow steam of very high density dark matter
can show up as the annual modulation in the detected dark matter signal.

Many researchers in this field assume that the distribution of Type A dark matter in the galaxy dark matter
halo around our Milky Way galaxy is uniform on the scale of earth. Therefore, they expect that if the dark
matter is detected with annual modulation in the deep underground laboratories in Italy and in Minnesota,
USA, then the same signal should also be detected in the other ten or more deep underground laboratories in
other parts of the world.

But my dark matter based theory in section 5 indicates that the distribution of Type B dark matter in the earth
is highly non-uniform. Those Type B dark matter particles trapped in earth gravity well are highly
concentrated in thousands of narrow streams of very high density dark matters oscillating in earth gravity
well. The width of such narrow stream of oscillating high density dark matter is only in the order of feet. With
such highly non-uniform distribution of dark matter in the earth, we cannot expect all deep underground
laboratories to detect the same dark matter signal. It all depends on whether the dark matter detector is
intercepting one of such narrow streams of very high density dark matter or not.

D.2.3. Why Ten or More Deep Underground Laboratories Have Not Detected Dark Matter?

Even though many scientists all over the world have been working on the research on dark matter for many
years, we collectively still do not know what dark matter is. Several potential candidates for dark matter have
been proposed and have been under investigation. A popular proposed candidate for dark matter particle is
known as Weakly Interacting Massive Particle (WIMP) which is thought to be about 100 times the mass of a
proton. With such assumption, many scientists were able to estimate the density of WIMPs in the dark
matter halo of our Milky Way Galaxy so that the dark matter halo provides the necessary additional gravity to
prevent the Milky Way Galaxy from flying apart at its observed rotational angular speed. Such estimation
indicates that all these deep underground laboratories should be able to detect reasonable number of
collisions per year of WIMPs with the dark matter detectors in these deep underground laboratories.

But the fact that ten or more deep underground laboratories have not detected any expected WIMP particles
in spite of several years of operation is giving us an important hint that the assumption of WIMP as a
candidate for dark matter may be wrong.

D.2.3.1. WIMP vs. Super-heavy Particle for Dark Matter

A possible way to understand and to resolve this great puzzle is that the actual dark matter particle may be
much heavier than the assumed WIMP candidate. For example, Dr. McCullen Sandora and his colleagues
recently (2016) proposed  super-heavy particle as a new candidate for dark matter particle. This proposed
super-heavy particle is heavier than WIMP candidate by many orders of magnitude. Such assumption of
super-heavy particle as a candidate for dark matter is consistent with my Important Finding 2 on extreme
high mass density of the core of the fountain of dark matter in Section 2.7. based on my research on
Mystery Spots and Gravity Hills.

Since super-heavy particle is much heavier than WIMP by many orders of magnitude, the required density of
such super-heavy particles in the dark matter halo to keep our Milky Way Galaxy from flying apart will be
lower than that of WIMP model by many orders of magnitude. Therefore, the probability of detecting such
super-heavy particles in these deep underground laboratories will be lower than that of WIMP model by
many orders of magnitude. In other words, it may take thousand years or even longer to detect a collision of
such super-heavy particle in galaxy dark matter halo with the dark matter detectors in these twelve or more
deep underground laboratories.

On the other hand, the deep underground laboratories in Italy and in Minnesota are able to detect reasonable
number of collisions per year with Type B dark matter because of extreme high density of Type B dark
matter in the narrow stream of Type B dark matter particles trapped and oscillating in earth gravity well.

Therefore, the probabilities of direct detection of dark matter among all those deep underground laboratories
can be greatly different by several orders of magnitude depending on whether the dark matter detector
intercepts one of those thousands of narrow streams of very high density dark matter or not.

D.2.4. My Prediction for Experiment Sites in Italy and Minnesota, USA

Based on my Hypothesis D1, the dark matter detectors in deep underground laboratories in Italy and in
Minnesota, USA are lucky to be intercepting one of the thousands of narrow streams of Type B very high
density dark matters oscillating in the earth gravity well. A signature of the narrow stream of very high
density dark matter is the existence of significant abnormal local gravity near such narrow stream of very
high density dark matter.  Therefore:

My Prediction 1 is that significant abnormal local gravity exists at the dark matter detector sites in Italy and in
Minnesota, USA.

It is, therefore, important to test my Prediction 1 at those two deep underground laboratories in Italy and in
Minnesota, USA.

Five methods to test for the existence of significant abnormal local gravity are described in Sections 2.3 to
2.8 in my companion Web Page (1) entitled “Eleven Sets of Evidences against Illusion Theory for Gravity
Hills and Mystery Spots” at:

This set of methods include (1) asymmetric pendulum, (2) strange behavior of land survey instrument, (3)
measured strength of local gravity differing substantially from that of normal earth gravity on earth surface,
(4) significant gravitational time dilation measured in such special location as compared to those in normal
locations, and (5) measurement of body weight at several locations in the area of interest.

Another simple method, Detector #6, is described on my web page at:

D.2.5. My Hypothesis D2 for the other ten or more Deep Underground Laboratories

My Hypothesis D2: The other ten or more deep underground experiment sites have not detected such dark
matter signal because they are not lucky and are not in those special locations that intercept one of
thousands of long and narrow stream of Type B very high density dark matter oscillating in the earth gravity
well.

My Prediction 2 is that there is no significant abnormal local gravity at those dark matter detector sites in the
other ten or more deep underground laboratories.

However, it is possible that some of these experiment sites may have significant abnormal local gravity but
still have not detected dark matter because the area of significant abnormal local gravity is in the order of
several hundred feet whereas the cross section size of the narrow stream of Type B very high density dark
matter is very small in the order of feet.

It is, therefore, important to test to see if Prediction 2 is correct or not for the other ten or more deep
underground laboratories.

D.2.6. How to Replicate the Detected Dark Matter Signal in Other Experiment Sites

My Prediction 3 is that to replicate the dark matter signal detected in Italy and in Minnesota, USA, one must
search for one of thousands of special locations that have significant abnormal local gravity and to locate the
dark matter detector carefully so that the dark matter detector intercepts the narrow stream of Type B very
high density dark matter oscillating in the earth gravity well.

It is noted that the abnormal gravity of the stream of very high density dark matter may cover an area of
several hundred feet as observed on several known Mystery Spot areas and on many Gravity Hills which are
typically several hundred feet in length. But the cross section size of the stream of oscillating very high
density dark matter are very small in the order of feet. Therefore, the hunting for and the measurements of
the significant local abnormal gravity must have great details to find the very small target area of the
maximum abnormal local gravity for placement of the dark matter detector for the experiment.

A possible method to find the precise location of the narrow stream of very high density dark matter is to sue
the free standing broom as a probe as described in my web page at:

http://
www.shltrip.com/Free_Standing_Broom.html

Appendix A provides another possible method to find the precise target location (Vortex) of the core of
fountain of very high density dark matter or narrow stream of very high density dark matter.

If significant abnormal local gravity is detected in one of such experiment site, but no dark matter has been
detected, it means the location of the narrow stream of very high density dark matter is not very far away,
may be only a few hundred feet or less. Special method(s) may be needed to find the correct direction to dig
a new tunnel from the current deep underground laboratory to reach the location of the narrow stream of
very high density dark matter. Then relocate the dark matter detector to this new location to intercept the
narrow stream of very high density dark matter.

If the detector is located carefully to intercept one of the long streams of very high density dark matter
oscillating in earth gravity well, it is anticipated that these additional experiment sites should be able to
replicate the dark matter signal detected in Italy and in Minnesota, USA.

There are hundreds of known special locations of Gravity Hills all over the world and several known Mystery
Spot areas plus many more yet undiscovered locations that are potential candidate sites for such deep
underground dark matter detection experiments.

However, not all Gravity Hills are equal. Some are stronger than others in the strength of abnormal local
gravity. It is better to pick a location with known strong effect of Gravity Hill Mystery or of Shrink-and-Grow
Mystery.

Furthermore, the location of the foujntain of dark matter or of the long stream of oscillating dark matter may
not be absolutely fixed, but may move slowly (oscillates slowly) over a range of a few feet as described in
Section 5.8. Such diurnal and seasonal movement of the location of the long stream of oscillating dark matter
must be taken into consideration in the selection of the optimal location for the dark matter detector.

Furthermore, the large deposit of heavy metal ore as the anchor for the long stream of oscillating dark
matter may not be always near the location of a known Gravity Hill or Mystery Spot area. Some of the
anchors may be near the conjugate point on the opposite side of the earth.

D.2.7. Measured Data from Italy and Minnesota Support Streaming Dark Matter

In the following News article entitled "
CoGeNT gives further backing to annual dark-matter variation" on the
results of dark matter detection in Minnesota, Professor Juan Collar compared his measured data from
Minnesota to those from Italy. In such comparison, Professor Juan Collar found that:

1. If the detected dark matter particles are assumed to be moving randomly in galaxy dark matter halo, then
the data from Minnesota and from Italy have conflict in WIMP masses and interaction strengths.

2. But if detected dark matter particles are assumed to be streaming in certain direction, then results from
Minnesota and from Italy overlap quite neatly.

This seems to imply that the detected dark matter particles in Minnesota and in Italy are streaming dark
matter supporting the prediction of streaming dark matter in my dark matter based theory derived from
Mystery Spot areas and Gravity Hills as described in Section 5.

D.2.8. Detection of Dark Matter Particles in Multiple Detectors in Deep Underground Laboratory

In the deep underground laboratory in Soudan mine in Minnesota, USA, the data analysis show that dark
matters have been found in multiple detectors. Some researchers take such data as evidence that what has
been detected here is not dark matter but is background noise because they believe that Type A dark matter
particle interacts so weakly with ordinary matter that it never interacts in two detectors.

But I believe that what have been detected in the deep underground laboratory in Minnesota are Type B dark
matter particles in the narrow stream of very high density dark matters trapped and oscillating in earth
gravity well.  With such understanding, the fact that dark matter have been found in multiple detectors in
these deep underground laboratories provides an important hint that the detected dark matter particles are in
a very high density stream, and the density of dark matter particles is so high that dark matter particles have
been found in multiple detectors. This finding from deep underground laboratory in Minnesota is, therefore,
consistent with Important Finding 2 in Section 2.7 that the mass density of the high density dark matter
particles must be at least 1,000 times greater than that of ordinary matter on earth surface as estimated
from Gravity Hill Mystery and Shrink-and-Grow Mystery.

With such narrow stream of extreme high density dark matter particles, it is possible and reasonable for two
or more dark matter particles being detected, each interacts with a detector such that dark matter particles
are detected in multiple detectors.

The detection of dark matter particles in multiple detectors in deep underground laboratories provide
important hint to stimulate some scientists to investigate certain special characteristics of dark matter to
answer the following important questions:

D.2.8 A: How high the density of dark matter particles must be in such narrow stream  in earth gravity well
such that dark matter particles can be detected in multiple detectors?

D.2.8 B: Is such estimated extreme high density of dark matter particles high enough so that the mass
density in such narrow stream is at least 1,000 times greater than that of average ordinary matter on earth
surface as indicated in Important Finding 2 in Section 2.7?

D.2.8 C: Is such estimated extreme high density of dark matter particles high enough so that the narrow
stream of such extreme high density dark matter particles can produce significant abnormal local gravity to
produce Gravity Hill Mystery and Shrink-and-Grow Mystery on earth surface as described in Section 1 in my
companion Web Page (1)?

D.2.8 D: How high is the estimated density of Type B dark matter particles in such narrow streams in earth
gravity well relative to that of Type A low density dark matter particles in the neighborhood of earth in the
dark matter halo of Milky Way galaxy?  Such great contrast in the density of dark matter particles may
provide good estimate on how many years it will take for other deep underground laboratories to detect
adequate number of collision events if their dark matter detectors are not intercepting such narrow stream of
extreme high density dark matter particles trapped and oscillating in earth gravity well.

D.3. Validate Successful Direction Detection of Dark Matter by Seven Sets of Evidences and Proposals

D.3.1. The signals from dark matter detectors in deep underground laboratories in Italy and in Minnesota,
USA indicate direct detection of dark matters. The 17 years of data has given the measurement in Italy a
statistical significance at 9.3σ – well beyond the 5σ that usually signifies a discovery in particle physics.

D.3.2. The detected dark matter signals in these two deep underground laboratories have annual modulation
because earth's orbit around the sun is not circular, but is elliptical as explained in Section D.2.2.

D.3.3. The measured data from Minnesota, USA agree well with those from Italy if the detected dark matter
particles are assumed to be streaming in certain direction. Such streaming of dark matter particles inferred
from data measured from deep underground laboratories is consistent with streaming of dark matter
particles predicted by my dark matter based theory which is derived from Gravity Hill Mystery and Shrink-
and-Grow Mystery.

D.3.4. The data from deep underground laboratory indicate detection of dark matter particles in multiple
detectors. This important experimental finding provides an important hint that the density of the dark matter
particles in the stream of dark matter particles is extremely high. On the other hand, my dark matter based
theory derived from Gravity Hill Mystery and Shrink-and-Grow Mystery predicts that the mass density of the
core of the fountain of dark matter on earth must be at least 1,000 times greater than that of ordinary matter
on earth surface. Therefore, both experimental data from deep underground laboratory and my dark matter
based theory derived from Gravity Hill Mystery and Shrink-and-Grow Mystery consistently indicate that the
densities of dark matter particles in the streams of dark matter particles in the earth are extremely high.

D.3.5. The dark matter detector sites in the deep underground laboratories in Italy and in Minnesota, USA
have significant abnormal local gravity which is a signature of the narrow stream of very high density dark
matter particles. (This is my prediction yet to be verified by measurements of significant abnormal local
gravity in those two deep underground laboratories.)

D.3.6. The dark matter detector sites in ten or more other deep underground laboratories have no significant
abnormal local gravity and have not detected dark matter signals because those dark matter detectors are
not intercepting any of the narrow streams of Type B high density dark matter particles trapped and
oscillating in earth gravity well. (This is also my prediction yet to be verified by measurements of significant
abnormal local gravity in those deep underground laboratories.)

D.3.7. Based on this theory, I also propose how to find suitable other locations for other deep underground
laboratories so that the direct detection of dark matter can be replicated in these additional deep
underground laboratories.

These even sets of evidences and proposals together provide a consistent and strong support to validate the
successful direct detection of dark matter in the deep underground laboratories in Italy and in Minnesota,
USA.

The validated successful direct detection of dark matter by human being for the first time will be an important
accomplishment and milestone in science.

It is also an important and necessary step to lead into the next phase of more advanced and close-up
experiments to investigate various characteristics of very high density dark matter at those special known
locations of Gravity Hills and Mystery Spot areas.

Appendix E: More Tests for the Dark Matter Based Theory for Gravity Hills and Mystery Spot Areas

Some important tests for validity of Hypothesis 2 on dark matter based theory have been described in
Appendix D as related to the deep underground laboratories for direct detection of dark matter on earth.

Some additional ways to test Hypothesis 2 on dark matter based theory are to

(a) examine the existing known locations of hundreds of Gravity Hills and several known Mystery Spot areas
to see if some of them are paired conjugate points on earth surface, and
(b) look for the significant abnormal local gravity at opposite (conjugate point) location on earth surface of
each of the know location of Gravity Hills and Mystery Spot areas.

There are five possible methods to detect the existence of abnormal local gravity at the opposite (conjugate)
location on earth surface. Four examples of such methods (detectors) are described in Sections D.2.3.
Several more methods to detect abnormal local gravity are described in my web pages at:

http://
www.shltrip.com/Detector_5.html

http://www.shltrip.com/Need_For_Precision_Measurements.html

However, searching for abnormal local gravity of the conjugate point on earth surface of a known Gravity Hill
(or a Mystery Spot) may not be trivial and may face some challenges. For example, if there is no paved road
with suitable uphill slope at that opposite location (conjugate point) of a known Gravity Hill, then existence of
abnormal local gravity at that conjugate point may not be so obvious.

Furthermore, if the conjugate point is in an ocean or a dense jungle with no easy access road, then existence
of abnormal local gravity at such conjugate point may not be easy to find. It is also possible that the
abnormal local gravity of a conjugate point may be buried under a huge and tall mountain. The area of the
abnormal local gravity of the core of fountain of dark matter is only a few hundred feet in size. If it is buried
under a huge and tall mountain of thousands of feet in height, then it is impossible to detect the buried small
area of abnormal local gravity.
