- How does gravity communicate from inside a black hole
How does mass determine the bending of space from inside a black hole?REPLY

A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape from it. This is due to the extreme curvature of space-time caused by a massive object.
Black holes are formed when a massive star dies and its core collapses in on itself. This collapse causes the star's mass to be concentrated in a very small area, creating a strong gravitational pull that forms a black hole.
The strong gravitational pull of a black hole can affect the surrounding space in a few ways. It can distort the paths of nearby objects, causing them to orbit around the black hole. It can also pull in surrounding matter, creating an accretion disk and emitting powerful radiation.
Once an object crosses the event horizon of a black hole, it is impossible for it to escape. This is because the escape velocity, which is the speed needed to overcome the gravitational pull, is greater than the speed of light. However, some particles can escape through Hawking radiation, but this is a very slow process.
Black holes are a consequence of the theory of general relativity, which describes gravity as the curvature of space-time caused by massive objects. Black holes are a manifestation of the extreme effects of gravity on space and time, and studying them can help us better understand the nature of gravity.
