Gravitational Waves have been Observed Directly

You can read about it here.

And thanks to Aaron Clauset and YY Ahn for posting an explanation from PhD Comics for how gravitational waves work (and the approach used in LIGO to observe them directly for the first time).

Here is a link to the CNN.com's article reporting the discovery.

gravitational waves are ripples in the curvature of spacetime which propagate as waves, travelling outward from the source. Predicted in 1916 by Albert Einstein on the basis of his theory of general relativity, gravitational waves transport energy as gravitational radiation. The existence of gravitational waves is a possible consequence of the Lorentz invariance of general relativity since it brings the concept of a limiting speed of propagation of the physical interactions with it.
