What is on the other side of a black hole?
No one Really Knows
Inside a black hole there is something called the event horizon, this is a part of the hole which has just enough gravity to pull light into the hole and stop it from escaping, because of this, if you were unlikely still alive. Because you are travelling at the speed of light, you would most likely see the back of your head. Once you get past this point of the black hole, everything would turn dark as if your were in a deprivation tank. you wouldn't know which was is up or how to get out and even be able to feel yourself.
