Dark Matter

For astrophysics and cosmology, there may be no important problems besides "dark matter". As the name suggests, the focus of controversy lies in the notion that large quantities of substances may be in the universe that can not be detected from the light it emits. The evidence of dark matter comes from the movement of celestial bodies, especially stars, galaxies, and galaxies / super galaxies. The basic argument is that if you measure the speed of an area, there must be enough mass to prevent all objects from scattering.

Cold dark matter provides the simplest explanation for most cosmological observations. It is a dark substance composed of ingredients and its FSL is much smaller than that of the original heparin. It seems that hot dark matter does not support the formation of galaxies and clusters of galaxies, and most particle candidates slow down in advance, so this is the focus of dark matter research. Studies of the Big Bang atomic synthesis and gravitational lens made most cosmologists believe that MACHOO does not constitute a small part of dark matter. According to A. Peter, "... ... the truly reasonable dark matter candidate is a new particle."

Familiar substances of the universe called baryon substances are composed of protons, neutrons, and electrons. Dark matter may be composed of baryon or nonbalance. In order to summarize the elements of the universe, dark matter must account for about 80% of the substance. Missing substances are more difficult to detect and may consist of traditional baryon materials. Potential candidates include light brown dwarfs, white dwarfs and neutrinos. Ultra large mass black holes may also be part of the difference. However, these hard to find objects must play a more important role than scientists observe to compensate for the missing mass.
