Research on Dark Matter Introduction For years, scientists have been searching for substances lost in space; it remains an unsolved mystery. Using various methods, scientists tried to determine the quality of the universe, but surprisingly found the difference. This indicates that there is no place to find a place where the mass of the universe is 90%. Then the word "dark matter" indicates this unknown thing in the universe. It is called darkness because it does not produce light or substance. It is called dark because we have to have some mass to explain the effect they produce.
This means that not only can the gravitational wave detector investigate the properties of the dark matter by examining these black holes, but also the gravitational wave detector has studied dark matter. Astronomers can observe the data through the correct (conceptual) lens. Of course, this idea also has problems. First of all, we know that not all dark matter can be composed of primitive black holes. Some of these original black holes will be within the mass range of star collapse and can therefore be detected by a gravitational lens that typically shows a black hole. The finished lenses demonstrated that at least some of the differences observed in the mass behavior must be due to the gravitational effect of some form of mass that normally does not interact with light.
In recent years, this problem is controversial. In 2016 - 2017, the idea that heavy dark matter or dark matter is a black hole (including the original black hole) appears again after gravity wave detection results. Although these were excluded again in December 2017, research and theory based on these continue until 2018, and it is not solved including the method of cooling dark matter. Dark matter can be divided into cold, hot and hot. These categories represent the speed rather than the actual temperature and indicate how much the corresponding object has moved by the random motion of the initial universe before the corresponding object decelerates due to the expansion of the universe.
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. Hot dark matter seems not to support the formation of galaxies and clusters of galaxies, and as most particle candidates slow down in advance, this is the focus of dark matter study. 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."
