I'm surprised bentware hasn't best me to the punch here, but there have been rumors(and only rumors) that we've detected the first gravitational wave at ligo.
As it stands today we have 2 facilities, one in Washington and another in Louisiana. A third is being built where upon completion if a wavebis detected, they will be able to triangulate the waves origin. With the 2 facilities as is, they can only narrow the origin down to a single plane.
They're pretty cool facilities and I had the opportunity to hear a few of the lead guys at the Washington site talk about their work and, at the time, the upgrades they were performing. It sounded like they were close and if this rumor is true they were. Its just a matter of noise reduction.
I'd like to get more in detail but mobile sucks. Its cool stuff though, understanding gravity waves can help us understand the fabric of spacetime.
