i think that gravity can be faster than light... i think this because in a black hole situation that light cant escape gravity... so that means the gravity is faster than light... or i would think this because of the theoretical particle... the graviton... if gravity can overcome light... so would that mean that a graviton...or just gravity can be faster than light?!? :huh:

The "speed of gravity" equals the speed of light. From Wiki:

 

"In the context of classical theories of gravitation, the speed of gravity is the speed at which changes in a gravitational field propagate. This is the speed at which a change in the distribution of energy and momentum of matter results in subsequent alteration, at a distance, of the gravitational field which it produces. In a more physically correct sense, the "speed of gravity" refers to the speed of a gravitational wave.

 

"The speed of gravitational waves in the general theory of relativity is equal to the speed of light in vacuum, c.[1] Within the theory of special relativity, the constant c is not exclusively about light; instead it is the highest possible speed for any physical interaction in nature. Formally, c is a conversion factor for changing the unit of time to the unit of space.[2] This makes it the only speed which does not depend either on the motion of an observer or a source of light and/or gravity. Thus, the speed of "light" is also the speed of gravitational waves and any massless particle....."
