Abstract

In the galaxy, there is only the "objective conditions of the center of mass is located near the center of the galaxy O--" ("cosmic spin" angular velocity ω, the spatial position Φ) "constant dark matter" relating to K0 and the "constant position" K1, and If the distance from the galaxy center O is set to r particle (celestial bodies) the velocity magnitude of v, G is the gravitational constant, there is "dark matter mass": M=K0vr2=（K1/G）vr2. This conclusion, and the current "astronomical" is consistent.

1."Dark matter mass formula"

In the galaxy, there is only the "objective conditions of the center of mass is located near the center of the galaxy O--" ("cosmic spin" angular velocity ω, the spatial position Φ) "constant dark matter" relating to K0 and the "constant position" K1, and If the distance from the galaxy center O is set to r particle (celestial bodies) the velocity magnitude of v, G is the gravitational constant, there is "dark matter mass": M=K0vr2=（K1/G）vr2. That is "dark matter mass formula": [1]

Figure 1

2."consistent with astronomical observations."

2.1."dark matter constant"

As the "dark matter constant" K0=K1/G =（2ωsinΦ）/G, and the "constant position" K1 related in "a different space 'latitude' Φ" where there is "a different constant dark matter", but compared in the "cosmic scale", we detect the "spatial scales" is still relatively small, so small differences in K0. It is possible that "small differences", resulting in the cosmic microwave background radiation (CMB) temperature anisotropy, affecting the polarization power spectrum.

2.2."dependent ordinary matter exists"

By M=K0vr2=（K1/G）vr2 can know, "dark matter mass" M proportional to the cube of the particle velocity is determined by the velocity of the particle formation is the "particle velocity produced a 'dark matter effect'." Therefore, we can say, "There is substance" and "substance relative motion" place only "dark matter", so the "dark matter" always "dependent ordinary matter exists," and the greater the speed, the more obvious manifestations.

Dark matter is not omnipresent, they gather only in some places into lumps, but was dismissive of the other places. Secondly, with overlapping images of galaxies, we see galaxies and dark matter are consistent position. Where there is dark matter, there are stars and galaxies, dark matter is no place, no nothing. ［2］

Figure 2

The figure shows that the so-called "rotation curve tracer," which is often used as the Milky Way galactic disk images. This tracer in blue and red, which is mainly by the relative motion of the sun relative to their decision. Spherically symmetric blue halo shows scientists suspect the existence of dark matter. ［3］

2.3. "Uniformly distributed spherical "

Outside of the "center of mass", The quality of the force generated by the center smaller and smaller, can think that the motion of a particle (celestial) affected only by "Coriolis force". At this time, approximately, to meet the v=K1r, v and r are "linear relationship". And there is：M=K0vr2= K0K1r3,can be considered "dark matter mass" M is was "uniformly distributed spherical "- the" dark matter halo ", [4] [5] and farther away from the center of the galaxy, the more the more evident in the performance of the periphery of the galaxy. For example, the "dark matter" in the periphery of the "bullet cluster" - the "large-scale" on "performance was" (blue): similar example is found only in a small number of huge clusters of galaxies - only occurs when there is a huge clusters of galaxies - that is when the monster hit each other. [6]

Figure 4

Measurement data shows two dark matter in dwarf galaxies evenly distributed across a larger area of a few hundred light-years. [4] [5]

Measurement of gas and stellar rotation rate allows astronomers can effectively "weigh" the host galaxy and determine its overall quality. These measurements show that the visible matter only explain a small part of the whole matter - the dominant material is dark matter. This technology will be applied to the Milky Way is possible, the peripheral part of the existence of dark matter galaxy is known. ［3］

Prior to this, scientists have always thought that this technology will be applied to the innermost region of the galaxy is very difficult, which is about 100,000 light-years wide. Now scientists have discovered Technical University of Munich innermost galaxy - including Earth location and our own "cosmic neighborhood" - direct observational evidence for the existence of dark matter inside. ［3］

Figure 5

They first created the most complete compilation of the measurement results of the galactic gas and stars of sport has been published. Then they compared the measured rotation rate and assuming the rate of rotation of the brightest galaxies in existence only when the substance. The results clearly show the contrast could not explain the measured rate of rotation, unless all around us, the presence of the central galaxy between us and a lot of dark matter. "We need to know that dark matter galaxy of stars and gas in order to ensure that we have observed in the rate of rotation." Conduct this analysis led by University of Munich • Pat Miguel (Miguel Pato) Dr. says. ［3］

2.4. "galactic rotation velocity curve."

If the quality of "center of mass" of m, the radius of the center of mass of celestial Q for r, Q size velocity v, then the factors affecting v There are two: one is "ordinary quality material" m, and the other is above "dark matter mass" M. That is: v2=G（m+M）/r=Gm/r +GM/r.

When the v is not big, In the vicinity of "center of mass", because the "dark matter quality" M=K0v3=（1/GK1）v3 small(compared to m), celestial body movement, mainly affected by "ordinary matter quality" m.

"Ordinary quality material" m, can produce "surround speed" v=√Gm/r, so that the outer galaxy "rotation curves down" (red line).

Figure 6

In the "medium scale", "dark matter mass" M satisfies v=K1r, v and r is the combined effect of "linear", and "ordinary quality material" m so that the outer galaxy - "galaxies" or "superclusters" other "medium scale", and for example, in the middle or the edge portion of the Milky Way," flat rotation curve "(blue line).

In the "larger scale", The quality of the force generated by the center smaller and smaller, because the v2=G（m+M）/r=Gm/r+GM/r,Gm/r≈0, then v2=G（m+M）/r=Gm/r +GM/r≈GM/r, and M=K0vr2=（K1/G）vr2, so v2≈GK0vr=G（K1/G）vr, that is v≈GK0r=K1r. "v" and "r" is proportional to. Therefore, the movement speed of celestial bodies, in "would be more large scale" is "up".

2.5. galaxy in "a hemisphere" clockwise, and in the "other hemisphere" anticlockwise

If the entire universe is rotating, then located in the two hemispheres of the galaxies of the universe there must be a different direction.

Researchers from the University of Michigan's Michael Longo and his colleagues used the summit in New Mexico Apache 2.5 m telescope, namely the Sloan Digital Sky Survey (SDSS), studied more than 15,000 galaxies in the universe after, in his report to the recounts: according to extensive research on the direction of rotation of the galaxy, either clockwise or counterclockwise rotation of the spiral galaxy, its direction of rotation is not random, but may be caused by the galaxy where the universe hemisphere of the decision.
