Instant gravity violates Einstein's relativity, since in any frame of reference, gravity would be faster than C. This is supported by black holes. Since light is not fast enough to escape a black hole, yet the effects of that black hole's gravity can be felt anywhere near it.
If gravity followed Einstein's Laws than black holes would have no gravitational influence on any matter near them, since if Light can not escape them, then obviously gravity traveling at C, in EVERY frame of reference, would also not be able to influence anything.
I think Eintsein is incorrect here.
Also the analogy of the bed sheet implies that gravity also acts instantaneously, since the dimple is always there. If one were to say travel faster than C and encounter the dimple, there would not have been enough time for gravity to travel to you in your spacecraft at C, but I am willing to but a pretty penny that gravity would still be felt.
The whole thing about gravity, light etc and black holes bothers me to no end.
So it is said by Einstein and many others that nothing can travel faster than the speed of light, not even gravity.
Well if the mass of the black hole is inside the event horizon and so much of it is gathered as a singularity in the center, then why do black holes have such a large gravitational influence on other objects?
Arguably the things that anchor EVERY single galaxy are black holes in the center. These prevent matter such as other stars from being ejected into space.
Well, if light can't escape a black hole, than why does gravity?
According to common theories, most of the gravity should be lost inside the black hole since gravity also travels as waves. This isn't so since we can easily see the impact that massive black holes have on the cosmos.
There is a small growing sector that believes in gravity acting instantaneously and this would be supported by black holes.
I am not a physics major, but can someone please explain this to me?

Yes, I am familiar with that analogy.
According to common thinking, the speed of gravity is equal to C, the speed of light.http://en.wikipedia.org/wiki/Speed_of_gravity
However, Isaac newton said that gravity acts instantaneously. http://www.space.com/scienceastronomy/gravity_speed_030116.html

This would confirm that it is faster than c.
