Because I am a nerd at heart, I love looking into things that have to do with the construction of our Universe. I yearn to find clues of how we exist and why. Anytime I see something of interest in science regarding our existence and new findings, I am drawn to research about it. This week I came upon a news article stating that European Scientists may have found a signal in space referencing the existence of dark matter. Of course at first I had no idea what Dark Matter was, but as I looked more into the topic, it became absolutely fascinating.
Dark Matter makes up about 85% of our Universe and it is everything we cannot see. So the question is, how do we know it is there if we cannot see it. Scientists judge the mass of dark matter by the gravitational affect it has on matter that we can see in space. Before 1930 the only matter we assumed was part of our Universe was the physical matter that we could detect. Basically, everything from our bodies to the stars. Then scientists named, Jan Oort and Fritz Zwicky came up with new information regarding the orbiting velocities and the amount of missing mass, to prove that Dark Matter exists.
The reason it is called Dark Matter is because we cannot detect it and therefore it is invisible. We know it is there because of the science behind the gravitational effects on visible matter. Scientists know that objects need to have a certain amount of mass to orbit at a certain speed. Yet, all objects in the Universe contain this “Dark Matter” because the amount of mass these galaxies have is significantly less than what they should if they were to rotate at their calculated speed. Therefore, scientists have been able to prove that there is something extra within these galaxies that is holding them in place, but it is invisible.
If scientists are able to uncover the truth behind Dark Matter and what it is made of, they will get closer to the secrets of how our Universe was formed and how it exists.
