Photons are not charged particles, so they should not be affected by magnetic fields. But according to General Relativity, they are affected by gravitational fields. Like Black hole eats light.

But dont they have a constant speed according to special relativity?

How can black holes "eat" light if the photons have one exact speed?

But dont they have a constant speed according to special relativity? yes they have constant speed. special relativity proves it. How can black holes "eat" light if the photons have one exact speed? the answer is our spacetime is curved. According to Newton's first law of motion "every body is at rest until no force acts on it and remain in motion until no force acts on it to stop it" but since our spacetime is curved therefor light vanishes if it nears to black hole.. And this make black hole to have most most even much gravity generator. Therefore light can't escape from black hole.

If i were to move close to a black hole, would it slow time?

I think i read about that.

no. it make time even faster as you never assume. let suppose you are coming from a sky towards Earth(free fall) then what will you feel. you will feel time is compressed for you since you will reach to Earth in some minutes because force of gravity will be acting on you. But black hole has millions times of gravity than Earth's gravity. Reality is you can't approach to black holes.

Yeah, but just theoretically, if you stayed in a black holes gravitational field for an amount of time, would it slow down my perspective of time? I pretty sure i read that in The Elegant Universe.

So that when you come out of the field you will have "traveled in time", since the black hole warps the fabric of both time and space.
