31. The gravity wave represents a perturbation around a stationary state, in which there is no velocity. 32. That would require signaling somehow with gravity waves . 33. Only signals that arrive simultaneously at Hanford and Livingston will be considered as gravity wave candidates. 34. Booker and Bretherton showed that vertically propagating gravity waves were completely absorbed at a critical level. 35. The possibility that LIGO will see gravity waves from black holes brings an additional bonus, said Shapiro. 36. :: The shape of a gravity wave is too complex to have a simple name, it seems. 37. They can be caused by gravity waves or turbulence, which can be related to convection or wind. 38. Exponential decay of EM waves occurs in dielectrics, however, and gravity waves are thought not so attenuated. 39. The Louisiana observatory uses minute fluctuations in beams of laser light to detect the pulsing of gravity waves . 40. Einstein's equations admit gravity wave -like solutions.
