- A representation of how space is distorted by a small black hole in orbit around a large black hole. This is the type of event that the space-based gravitational wave detector, LISA (for Laser Interferometer Space Antenna), hopes to detect.

The Hunt for Gravity Waves
In his 1916 theory of general relativity, Einstein predicted the existence of gravitational waves, but only now are scientists close to actually seeing them.
Sound cannot exist in a vacuum. It requires a medium, such as air or water, through which to deliver its message. Similarly, gravity cannot exist in nothingness. It, too, needs a medium through which to deliver its message. Einstein theorized that that medium is space and time, or the "spacetime fabric."
