1. Other candidates are gravity waves from the interior that dissipate in the atmosphere. 2. Unlike surface gravity waves, internal gravity waves do not require a sharp interface. 3. Because other things also travel at the speed of light like gravity waves . 4. :Maybe gravity waves can escape from a black hole but light waves cannot? 5. Unlike surface gravity waves , internal gravity waves do not require a sharp interface. 6. And gravity waves are to gravity, what em waves are to em radiation. 7. The pattern is of atmospheric gravity waves above the surface of the ocean. 8. Any such signal would be readily distinguishable from effects of gravity waves , he said. 9. LIGO should detect when a gravity wave makes space shrink by a little bit. 10. He also actively supported the Glasgow Project, which sought to detect cosmic gravity waves .
