Black holes are one of the most mysterious objects in the Universe. They consist of an immense amount of matter packed into a tiny volume, giving them enormous density and gravity. The gravitational pull is so high that not even light can escape, so they are invisible. These objects have puzzled astronomers and physicists for decades - what is a black hole and what do we know about them?
Black hole structure
The black hole structure consists of two significant parts: an event horizon, and a singularity.
A black hole is the point of no return
The event horizon of a black hole is the boundary where the gravitational pull becomes so strong that even light cannot escape.
Descent into a black hole would result in certain death to us humans due to the high gravitational force. But if we could, what would happen if we traveled into a black hole?
A black hole is Spaghettification: a cosmic stretch machine
If one were to enter a black hole, they would be stretched apart by the force of gravity.
