Why can't light escape from black hole?

Answer 1

no because black holes are so amazingly dense that nothing can escape. also that when something enters a black hole the denseness automattically crushes it after it sucks something in like a vacuum.

No. That is how a black hole is defined.

Real Answer: Once light crosses what is called the event horizon (Point of no return even if your traveling at the speed of light ) 3.2 x 10^8 m/s , that 3.2 with the decimal moved to the right 8 times meters per second.meaning it gets close enough so that the inward force of gravity that the black hole produces (unfathomable) creates a verticle velocity of the speed of light and bends the light inward into the black hole where it never escapes. Or you could say that it creates an enormous inward horizontal gravity force that will bend that light because as E=mc^2 explains , Energy is the square of the mass of an abject times the speed of light squared. or we could say that the mass of an object is the speed of light squared divided by its energy ( Kenetic plus potential).

To simplify things: A black hole is defined as 'a region of space from which nothing can escape'. This may need a little explanation.

The first thing you need is a singularity. A singularity is an object which is both very small and very heavy, so it has a very large gravitational field strength. Around the singularity is something called the event horizon. This is not a separate entity but is the name we give for the 'edge' of the black hole. The gravitational effects of the singularity can be felt outside of the event horizon. The event horizon merely marks the 'boundary' between ordinary space and space which nothing can escape from (also know as a black hole). The reason nothing can escape from a black hole is that the gravitational force exerted by the singularity pulls things towards it so strongly that the only way to escape is to travel faster than light. Nothing can travel faster than light so nothing can escape. The field strength is so great that even light 'falls' towards the singularity.

I hope that makes more sense (I don't know what the above are talking about vacuums and energy-mass conversions for, it just seems to complicate it)

Answer 2

Gravity takes the form of a field around an object with mass. The mass 'curves' space time around it, causing nearby objects to be attracted towards it. Therefore gravity does not need to 'escape' from a black hole, the strong gravitational field around it is the reason other things cannot escape from it.

Answer 3

This is due to the huge gravity by the black hole. What actually happens is that this gravity distorts space and time in such a way that anything, whether it moves at the speed of light or less, can only move closer to the black hole's center, not away from it.

Answer 4

It is impossible for light to escape a black hole because the gravitational pull is too strong.

Answer 5

It's technically possible through a process called Hawking radiation. However, normally, no, it is not possible for light to escape from inside a black hole's event horizon.

Answer 6

No. Light cannot escape the black hole, that's why they are black - NOTHING escapes them - they are God's ultimate vacuums.

Answer 7

This is because the gravitational pull of the black hole is so strong that the escape velocity reaches the speed of light.

Answer 8

no
