Since gravity moves at light speed, does Earth orbit where sun was 8 min. ago?

- overu589 2y agoI’ve wondered the same. I actually think they’re all liars (science fraud in the double billions) and gravity is a standing, not propagating wave. I believe the Earth will not continue its elliptical orbit, it will vector onward immediately.

Here is another explanation from theoretical physicist: https://math.ucr.edu/home/baez/physics/Relativity/GR/grav_speed.html https://math.ucr.edu/home/baez/physics/Relativity/GR/grav_sp... >one finds that the "force" in GR is not quite central—it does not point directly towards the source of the gravitational field—and that it depends on velocity as well as position. The net result is that the effect of propagation delay is almost exactly cancelled, and general relativity very nearly reproduces the newtonian result.
