Black hole is a celestial body whose other cosmic speed is greater than the speed of light so that not even the light can run from it. Space in which large mass is compacted in small space, due to which after it crosses black hole boundary (so called, event horizon), nothing, not even light can escape the gravitational force of that mass. Laws of physics tell us that the more mass a body has, its gravitation is greater.

Black holes are considered the densest and with it most massed objects in space, so, their gravity is greatest. One of fascinating theories tells us that in the future we will travel through time via black holes. It is theoretically possible but the problem is that we cannot control holes so we don’t know where it will throw us. Theory that would enable us to do that tells us that each black hole ends with a, so called, white hole that expels everything that enters the black hole. Second problem is that there is no transportation vehicle that could withstand the pressure of the hole and we would most likely burn up within black holes.
