From my internet research I gather that they are very hard to detect but is that because the energy carried by the waves is so tiny or because it is hard to get that type of energy to interact with an instrument in a measurable way? Do gravity waves, as a form of energy, have their own gravitational field? That is to say, if a gravity wave passed close to a stationary object would it be deflected and would it alter the velocity of the object, like light waves are and do? Is the speed of a gravity wave c in all reference frames? What about gravity waves that are high in frequency but low in amplitude such as those that would be generated by an atom as it moves about due to its thermal energy? I would assume that the energy carried by a gravity wave would depend on both amplitude and frequency. Is there any research being done in this area?
