exactly the speed of light, same as always. however it is doppler shifted. even very low frequency radio waves falling toward the black hole, by the time they hit the event horizon and vanish forever have blue shifted to become gamma rays. similarly even gamma rays rising away from the area immediately above the event horizon, by the time they escape have red shifted to become very low frequency radio waves.
Yes, everything can be sucked in to a black hole, even light
The black hole nearest to our Earth is (fortunately) several thousand light years away. No human has been farther from our Earth than our Moon. Thus, we are technologically quite a ways away from being able to travel to a black hole.
you dont light gets sucked into a black hole. Light!!!! so you have no chance. Additionally being exposed to spac would make you explode
A black hole's gravitational pull is so strong, not even light can escape it. so, essentially, it's like the light is being sucked up into a black void.
There are hypotheses about so called 'virtual particles' that may travel faster than speed of light, and hence are not sucked up by Black Holes. Also, Black Holes cannot suck another bigger Black Hole, when they meet a bigger one, they get sucked up rather.
The gravity casued by the black hole is so strong that even light is sucked into it
no, it just gets sucked into it
Because they give off absolutely no light and no radiation. The only radiation is X-Rays from the stars being sucked in.
Everything that is slower than the speed of light (approximately 186,000 miles per second) gets sucked in. Since nothing is faster than the speed of light, magnetism can definitely be sucked in
It is sucked into the black hole to a point that is infinitely small.
No, because nothing can escape the black hole, not even light. So without light, we can't see anything. but, we can see stars being stretched like spaghetti and then being sucked into the black hole.
Because the nearest one is 1600 light years away. Even if someone traveled at 80% of the speed of light towards there, it would be two millenia before s/he got there.
