Dark matter is something that an astronomer or scientist cannot observe through ordinary telescopes. It does not emit or absorb light, and is considered responsible for holding all the normal matter in the universe together. Normal matter is something which can be observed and recorded through available means of technology. This article lists some very interesting facts about dark matter.
Any and every fact about the universe originates from the famous Big Bang theory. This theory is based upon the idea that the universe, from the time of its conception, is expanding rapidly. The universe was formed around 13.8 billion years ago after a violent explosion, which gives the theory its name. As the universe gradually cooled down, the billions of protons, neutrons, photons, and electrons, which were formed as a result of the big bang, combined to form hydrogen and helium.
Further, hydrogen and helium combined to form giant clouds, that would form galaxies. During this period, some of the first stars were formed. As the universe grew older, planets and galaxies were formed, making the universe the way we see it today.
There are still many mysteries about dark matter that need to be unfolded, but astronomers and physicists have gathered evidence about its presence.
