What is Dark Matter
The universe is very vast and has so much to offer. Despite that, we don’t know very much about it which is a shame. But what we already know is not only unnerving but absolutely mind-blowing too. So much so that scientists all over the world are confused by it as well.
Almost 95% of the mass of the universe is made up of a dark matter. Now, some science fanatics may know what is it while others may have only heard of it in sci-fi movies. Dark matter does not emit light or energy. So how do we know it’s even, well, there?
Hypothesis’ since the 1920s have suggested that there is more matter than what can be observed and ever since then, this hypothesis has been solidifying into a real theory. Pieter van Dokkum who is a researcher at Yale University said that the motions of the stars dictate how much matter there is. It doesn’t matter what type of matter it is. He also happened to lead a team that identified a galaxy called dragonfly 44 which is made up of almost entirely dark matter.
