Question

What is a black hole? What is at its other end?

Answer 1

A black hole is a region of spacetime where gravity is so strong that nothing that enters the region, not even light, can escape

Theories point to the idea that the inside of a black hole, is mathematically speaking, an area of infinite imploded mass. Specifically, gravity becomes so dense in it's vacuum, that everything is both torn apart, and compacted at the same time, yielding a negative mass until the point which it's simply broken into dark matter, and re compressed, and so on.

In short...nothing besides matter, space, and energy is on the "other side".

hope you get it right!!
