Gravity does not travel at the speed of light. Some speculate that instant (ie: faster than light) communication could be possible by manipulating gravity.

- krapp 5y agoGravity does travel at the speed of light. This is required by general relativity and was confirmed by observation multiple times[0,1].

- Diggsey 5y agoNot sure where you got that idea. The effect of gravity does travel at the speed of light (this is why gravitational waves exist). https://en.wikipedia.org/wiki/Speed_of_gravity https://en.wikipedia.org/wiki/Speed_of_gravity
