A black hole is like a giant drain in space. Everything that gets too close gets swallowed — even light. The black circle in the center is the "point of no return": if light crosses it, it never comes back.
Imagine space is a bedsheet. Einstein said heavy objects curve it (like placing a bowling ball). But what if they also twisted it, like wringing out a towel? That's torsion: space doesn't just bend, it also twists. Move the slider to see what happens.
