what happens when light goes into a black hole & why do people ask?

Answer 1

People ask because that kind of gravity would pull a person apart (cause disintegration) in milliseconds. Gravity in black holes is so strong it would crush anything we as humans know of to be the strongest solid material, even diamonds.

The gravity of black holes are so strong that light can't escape them. Light gets sucked into black holes because of the intense gravity. It's similar to the extreme pressure forces near the bottom of the ocean, but in a non-h20 environment way and it's much more extreme than anyone can imagine

Answer 2

I think people ask these sorts of questions because they lie so far outside our everyday experience and so make us wonder about the universe we live in.

What happens to light depends on what you mean by going into a black hole. You could mean crossing the event horizon or entering the singularity at its heart.

For the former, not a lot special. It would carry on moving in a trajectory determined by gravity towards the centre (this may not be a straight line - it may indeed spiral inwards). For a very large black hole, the event horizon is not even a very curved region of space. For instance, the black hole at the centre of our galaxy has an event horizon whose curvature is about 6 times that here on Earth.

For the latter - well, we do not really know precisely.

Answer 3

The theory of what happens to light in a black hole is that, since the gravity of the black hole is so strong, it sucks the light into it so that it can never come back out. I would assume that it is brought up so much because it takes a tremendous amount of gravity to suck up light and also because black holes are open to a lot of discussion.

Hope this helps!

Answer 4

It would continue to travel at the speed of light, but it would be in just one place and time would cease to exist so it really wouldn't be moving at all. Not that anyone could detect it though. Why? Because they are curious.
