APOD 3.8

Today's APOD is from march 18th and is very cool as it is on the topic of a paradigm altering fact about the origin of the universe.

The photo above is a picture of the BICEP2, a satellite in the South Pole, and the readings it took of some gravitational winds. The big bang theory is not only a popular tv show, but also the theory about the origin of the universe that it all began as a hot dense object the size of a marble and it one day exploded. The theory states that the universe is still expanding but there has never been legitimate proof until now. These gravitational winds are proof of the expansion part of the BBT! And it all began 13.8 BILLION years ago, and now, on march 17th 2014, we have conclusive evidence of the process. I chose this because it is an important hallmark in the history of science and I find it amazing.
