Einstein said it. Now we know it!
100 years ago, Einstein wrote down his famous theory of relativity, along with one other "small" theory concerning gravitational waves. Supposedly, each body in the universe exerts a certain pull that is able to warp space and time.
Fast forward 100 years, to this week precisely, and scientists have finally found real, audible proof to his theory! They were able to listen to the fusion of 2 black holes - the smaller one being 30 times bigger than our sun - happening 1.3 billion years ago. Scientists who were ready for comment were absolutely giddy, saying that this new groundbreaking discovery will change everything they know and practice in the field of astrophysics. Nothing this big has been found for a very long time, not since radio waves and magnetic waves!
OK! So... is it time for that time travel trip or not just yet?
