Does gravity travel instantaneously?

Does gravity travels instantaneously? Or it travels equal to the speed of light.

Answer:

No clear answer now. If we believe in the Theory of relativity, Gravity (Gravitational Waves travel with the same speed as that of light in vacuum. If gravitons are like photons, then it makes sense too.

However I invite you to think more and post your thoughts as comments here. Let the discussion begin.
