WebOct 16, 2008 · In the dispersal of gravity waves would be along the time dimension. Take as example the case of two neutron stars orbiting close to one another: As one neutron star passes through a particular point in space, it causes an increase in the gravitational curvature of that area, which equates to a "peak" in the gravity wave pattern. WebJan 27, 2024 · This is free fall, this is gravity, this is a large scale motion interpreted as a consequence of local curvature. Example: Original separation between \(\mathrm{A}\) and \(\mathrm{B}\)-and every other pair: 20 meters. Time of observation: 8 seconds. Shortening of separation in that time: 1 millimeter. Fractional shortening: 1 millimeter/20 meters

[Google Scholar] [Green Version] WebSo usually, people don’t say that velocity causes space-time curvature because it is a relative quantity. It is still an important point that moving objects do result in space-time curvature and therefore gravity – it is not possible for an observer to be at rest relative to all moving objects. This is true even without using General Relativity.
