Dark Matter



It seems the search to prove the existence of the elusive Dark Matter might soon come to a close. A Minnesota mine, half a mile under ground, seems to have detected the existence of Dark Matter. For those of you who don't what Dark Matter is, I'll give a brief explanation. The ordinary matter that we can visibly see makes up an estimated 15.5% of the universe. Planets, Stars and pretty much everything else in space is made up of ordinary matter. However 84.5% of the universe's matter is estimated to be Dark Matter. Dark Matter differs from regular matter in the way it interacts or lack of it. Dark matter doesn't emit light or radiation or create a electrostatic or strong nuclear force. So how do we know it exits? Well it because dark matter still has gravitational effects on visible matter. My understanding is that galaxies form spirals because of gravitational effects between the matter in the Galaxy. However our calculations show there isn't enough mass in many of these galaxies to hold them together, therefore we believe that dark matter exists and holds galaxies together. Because dark matter doesn't interact much with regular matter, proving its existence is very difficult. Any ways using a super conductor cooled to 50 millikelvin physicists think they have detected dark matter.

Woah.... Ruits I know you have kind of tried to explain this to me in lunch, but this is sooooo interesting and my brain feels a little weird. I'm am very interested in learning more about "Dark Matter"
