Black hole with jets

The gravitational attraction of a black hole is so strong that not even light can escape it. As a result, black holes are one-way doors in the Universe. No-one knows what goes on inside, except that matter is compressed to incredibly high density.

A jump into a black hole is a one-way trip. Black holes are regions of space where gravity is so strong that nothing can escape them, not even light. Even before you reach the event horizon — the point of no return — you would be “spaghettified” by the black hole’s tidal forces. Astronomers do not actually know what goes on inside black holes. Current theories predict that there is a dimensionless point with infinite density at the very centre of every black hole. But current theories may be wrong.
