at what point does the light stop moving at the speed of light and reverse? does that point have a name? is there a point like that? and woulded there be alot of energy expended when it reverses?

so that means that the gavity waves are faster than light or stronger? hmmm thanks guys your all sweetys with brains haha. have i got the girl for you!!!! oi!!!! haha

Light does not slow down, it's speed is constant through any given medium.

When light gets "sucked in" to a black hole, what is actually happening is that it is pulled into a gravity well from which it can not escape, but it is still graveling at the same speed.

That speed is just not enough for it to climb out of the hole.

gravity waves move at the speed of light. The strenght however can be the equivalent of more acceleration than light can overcome.
Don't forget, time slows down the stronger the gravity is. So if light is going 186,000 miles per second... what's a second in a black hole?
MAYBE it IS going a "normal" speed, but time is so slowed down, that the light never gets out during the existence of the black hole.

The light near a black hole never slows down or speeds up. It always travels at the speed of light. But the gravity of the black hole warps space-time in such a way that the light cannot escape the black hole even at its high speed. This cannot be understood in everyday terms, you have to do that math. And the math involved is EXTREMELY advanced. See the source.

Hi. Photons (light wave/particles) always travel at the speed of light in the medium in which it moves. Near a black hole the space is distorted so severely that light just orbits extremely close to the event horizon. It does not actually stop.

Light always moves at the speed of light. What happens is the intense gravitational field warps space-time so that the light travels back into the black hole.

That point is called the Event Horison. It's the point at which the escape velocity equals the speed of light.

The speed of light remains constant. The gravity well created by a black hole warps space-time thereby changing the direction of light. If the light passes close enough to the black hole, the direction change is into the black hole.

you will desire to understand approximately that region of a black hollow called the 'adventure horizon.' think of of it as certainly one of those boundary -- for something exterior that boundary this is nevertheless plausible to flee from the region around the black hollow. in case you had a useful adequate spaceship you would be able to desire to attitude the form horizon and via expending adequate power stay exterior it or maybe pass away. as quickly as something passes the form horizon nonetheless this is long previous continuously. Now think of of each and all of the textile being drawn in the direction of the black hollow. because of the super gravity this textile gets speeded up as much as close to the cost of light. through friction between those extreme-velocity debris, xrays are generated. as long as those xrays do not pass interior the form horizon they'd and do radiate off into area for us to locate.

gravity waves are not stronger than light and they move at the same speed as far as we can tell. light doesn't stop it just changes direction
