G-Waves is a buzzword recently :) At the beginning I thought G-waves as the propagation of the changes of the curvature caused by a mass when the status of the mass (e.g. value or location) changes......But moment ago, I was told that G-waves are different from the waves that transmitting the change of curvature caused by mass. More specifically, when the distance between earth and moon changes, there are TWO kinds of curvature related WAVES are emitted: 1) the change of curvature due to the gravity change as the distance changes; 2) the Gravitational Waves. Both are predicted by General Relativity. For the example of Earth and Moon, more specifically I was told that near the Moon (or Earth), the first type of waves are bigger than Gravitational Waves, but beyond certain distance from the Moon (or Earth), the first type of Waves die out quickly. Since I am not a physics professional, even though I trust very much the professional qualification of the person who told me the above info, I still would like to get it confirmed from another physics professional because no one on the internet is saying so even though many are talking about Gravitational Waves these days. Thanks in advance!
