I am pretty sure that that is impossible since gravity doesn't move at all. Things move because of gravity, but gravity itself doesn't move.

If the affects of gravity did travel faster than the speed of light, it would violate relativity. The affects of gravity propagate throughout space much like waves do. If the sun were to disappear or become a black hole instantly, it would take at least 8 minutes before it affected us.
Nothing can travel faster than the speed of light. This is one of the fundamental consequences of relativity.

There's a lot of speculation when it comes to gravity. The real answer to your question is: No one knows.
It is the topic of a lot of studies, whether the effects of gravity are felt spontaneously after an distant object dissapears, or whether the gravitational effects propagate at the speed of light, or maybe slower. It is not known at this point in time, the technology to make such measurements do not exist.
Just imagine: F(gravity)=(m1.m2.G)/R^2
where R is a huge number!!!! no way to measure that from earth.
There are many theories posted by several scientists on this topic, but remember, they are only THEORIES, none of these have been PROVEN into LAWS.

The carrier of the gravity force is postulated to be the 'graviton'. The graviton carries the force of gravity at the speed of light, although the effect of gravity will never be as fast as it's carrier.
The only argument against this are Black Holes, where not even light can escape.......it's an interesting debate - but I would say photons and gravitons travel at the speed of light.

Gravity is a force, not a moving entity, so doesn't have a speed. There is no sensible comparison beween it and light. According to theory there are probably gravity WAVES which travel at the speed of light.

fine let's see....
in gravity , acceleration a=9.8 m/s2 on earth.for a body falling for 5 seconds,,,,
v=u + at. since u=0,,
v=9.8*5 = 49 m/s.
but speed of light is 3 * 10^8 m/s so ofcourse light is faster for a time span of 5 sec.
one more point u r trying to compare two things of different dimensions which is not possible. g is acc due to gravity whereas speed of ligght is speed

No, it isn't. As far as we can tell, the effects of gravity travel at the speed of light.

No, sun light is faster than gravity. If you want to confirm ask any since professor.

Yes it is. The earth would spiral into the sun quite quickly if it wasn't. The structure of the galaxies is also evidence of quick acting gravity. Read this article http://metaresearch.org/cosmology/speed_of_gravity.asp.

It can't be measured the same way. Gravity is pull. It does not pull any objects nearly as fast as light travels, if that answers your question.
