Calc Speed: Warping Space with Mass & Infinity

[Jake Minneman]

Is it possible to calculate the speed at which a massive object warps the fabric of space? Does the mass of said object directly effect the rate at which the fabric is warped? What would happen if the said object was infinitely massive?

gravitational waves travel at the speed of light

If you are using General Relativity as the theory then all changes to the metric of spacetime propagate at c.

1. If the mass is constant and moves inertially, then there is no change to the "warping" relative to the mass's position
2. If the mass accelerates, any change in the "warping" moves at the speed of light, as others have said
3. There is no such thing as an infinite mass so the last question has no answer
