Science Fact #3 The Vast Nothingness

This is Dark Matter

Space, we see space as a medium, and in outer space there is no difference. although some people think that the space consist of nothing, they are far off, new things are being found everyday in outer space, not only that scientist have found a matter outside our reach and vision, a mater that interacts with the whole universe, but we human can not comprehend. This matter is called Dark Matter, this matter is like i said unidentified, but this unidentified matter makes up 27 % of the mass and the total energy output of our whole universe, and that is huge yet we are not able to detect nor interact with it. How does scientist know this matter exist, well they don't this is just merely a theory that many scientist come up with, since our universe keeps on expanding and it goes faster everyday so there must be a matter that helps with this process, that is where the theoretical matter "Dark Matter" comes in to play.
