I could write a lot on this, but this info-graphic will do for now. The implications are mind bending. It just got real. Inflation theory got a big boost. Einstein is just the man. Multiverse? This has got everything you could ever want. This doesn’t answer everything but it’s as if we are hitting a T intersection and now knowing which way to turn.
This is insane when you realize that as abundant and obvious gravity is, gravitational waves and such have just been theory. It has been unobservable until now. It’s not directly visible, but when these scientists had good enough gear, they were almost able to map a small section of the universe’s thumbprint.
