How does space behave around a black hole's edge?

Imagine you're standing at the edge of a swimming pool, looking at the water's surface. As you get closer to the edge, the surface appears to dip and curve around you, almost as if you're looking at a warped piece of fabric.

A black hole's gravity is so strong that it bends space around it, much like the water's surface curves around you at the pool's edge. This bending creates a boundary called the Schwarzschild radius.

Example

If you were 1 meter away from the Schwarzschild radius, the space would curve around you as if you were 1 meter away from the edge of a pool.

Remember this

The Schwarzschild radius marks the point where space itself starts to curve so much that not even light can escape, making it the black hole's boundary.
