Gravitational waves that are 'sounds of the universe'
Einstein wrote about them, and we're still looking for them -- gravitational waves, which are small ripples in the fabric of space-time, that many consider to be the sounds of our universe.

Gravitational wave
In physics, a gravitational wave is a fluctuation in the curvature of spacetime which propagates as a wave, traveling outward from the source. Predicted by Einstein's theory of general relativity, the waves transport energy known as gravitational radiation. Sources of gravitational waves include binary star systems composed of white dwarfs, neutron stars, or black holes.
Although gravitational radiation has not yet been directly detected, it has been indirectly shown to exist. This was the basis for the 1993 Nobel Prize in Physics, awarded for measurements of the Hulse-Taylor binary system. Various gravitational wave detectors exist.
