Back in the early 1900's, one of the many cool things Einstein found through his theory of General Relativity, was the theoretical existence of these things called Gravitational Waves.

As their name suggests they are predicted to be ripples, or fluctuations in the curvature of Space-Time, that propagate the way waves would, emanating from a source such as a black hole, neutron star, binary star, or any other ridiculously super massive object.

Apparently, Space-Time itself is curved, and becomes more or less curved depending upon the objects held in it. The more massive the object held in space-time is, the more curvature develops there.

When a highly massive object moves or gets accelerated, it affects that Space-Time significantly enough to cause these ripples or waves. The energy the waves carry and transport is called Gravitational Radiation, which travels at the speed of light and loses strength as it propagates, but never stops or even slows down.

Although there has yet to be direct observation of these waves, there is plenty of data to support their existence in the form of indirect observation. Like the observations of orbits of binary pulsars, that seem to be losing orbital energy at the exact rate that General Relativity predicted they w . . . More
