Faster than light?

[*puffy* japanisthebest]

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?!?

thx alot

Even if gravity is lesser speed than light, gravity can still "come in contact" with light at angles.

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....."
