Question

Does its gravity field compress when an object travels at almost the speed of light?

Answer 1

Does its gravity field compress when an object travels at almost the speed of light?

❱ To begin with, the speed of gravity has not been measured directly in the laboratory—the gravitational interaction is too weak.

Answer 2

Gravity field is very weak so the object will not compress if it travel with the spees of light. Gravitation are massless, and travel at speed c, SR rules apply to them the same way as to photons.

So gravitons will seem (or the gravitation effects) to propagate at speed c from all inertial reference frames.
