It's only super awesome! They measured the signal from two black holes that were orbiting around each other until they merged. The NYT has a pretty good video that explains what's going on (the NYT data visualization people do amazing work in general) http://www.nytimes.com/2016/

"Gravity waves" were something that was predicted a hundred years ago, and we've been looking for them ever since! The story of their prediction is kind of funny. Einstein came up with general relativity, but it was someone else who used it to predict that general relativity allowed "gravity waves" to exist. Einstein made some calculations and was all like "no you're wrong, waves are not possible" but he had made a mistake - and when he tried to publish this, the journal was like "bro u messed up" and he was like "no u" and got super pissed off and boycotted them for the rest of his life.
It turns out that the frequencies are actually in the normal range of human hearing, so we can make a sound out of them! https://soundcloud.com/emily-
