Dark matter is a hypothesized type of matter that is thought to make up about 85% of the universe's matter.Dark matter is so-called the dark matter because it doesn't seem to interact with the electromagnetic field, which means it doesn't absorb, reflect, or produce electromagnetic radiation like light, making it hard to detect.Any material that primarily interacts with visible matter through gravity is referred to be dark matter. Although dark matter has not yet been directly seen, it must rarely interact with other regular matter and radiation other than gravity. We have only barely explored space and are not even sure about many theories that we have created regarding space,time and matter. Dark matter is a part of the cosmos that can only be detected by its gravitational pull, not by its brightness. Fritz Zwicky of the California Institute of Technology first used the phrase "Dark Matter" in 1933 to refer to the invisible substance that must exist in one aspect of the cosmos. Since it is dark, we cannot see whether it is in the forms of Stars or Planets. Dark matter is not made of baryonic clouds because then we could have seen the matters absorbing the radiation which passes by it.One popular theory holds that dark matter is made up of strange particles that have no interaction with ordinary matter or light but yet have gravitational force.Even between the Earth and the moon, dark matter comprises to almost 24 trillion tons.Galaxies were formed in large part as a result of dark matter.
Dark matter, which makes up the majority of galaxies' and galaxy clusters' mass, also gives galaxies their large-scale structure. Meanwhile, we refer to the mysterious force behind the universe's fast expansion as dark energy.Your physical body would crumble if all of the atoms in it were converted to dark matter atoms. Without ordinary matter, your atoms wouldn't be held together any more, which is why dark matter is very dangerous . Galaxies would lose a significant portion of the gas that creates new stars just after the first significant star-forming event they experienced if dark matter didn't exist. According to recent research, one kind of dark matter may act like small, high-speed projectiles that may penetrate human tissue like bullets. In reality, the heat from the dark matter hit would tunnel through biological tissue as a plasma plume, dissolving flesh. There is dark matter even inside you but not too much. Dark matter particles may even be able to go straight through our globe without losing any energy because they can pierce all other types of stuff. On the other side, they could be significantly hampered and lose energy if they collide with the common substance that makes up Earth. Nothing bad will happen.
