How Does Best of: Neil deGrasse Tyson Explains Black Holes Work?

A black hole is like a super strong vacuum cleaner in space that can’t be turned off, and it’s really good at sucking things in.

Imagine you have a big, heavy beach ball and you throw it into a pool. The water doesn’t just ripple, it gets pulled toward the center, right? That’s kind of how a black hole works, but way more intense. Black holes are made when huge stars collapse under their own weight, creating an incredibly dense point called a singularity.

What makes a black hole so strong?

Think about a trampoline. If you jump on it, it stretches out, that’s like gravity. Now imagine a black hole is like a person jumping really hard on the trampoline and not stopping. The more massive something is, the stronger its gravity. A black hole has gravity so strong that even light can’t escape once it gets too close.

What happens if you fall into a black hole?

If you fell into one, you’d get stretched out like spaghetti, that’s called spaghettification. But don’t worry, your feet would feel the pull first, and then your head. It’s not magic, just really strong gravity doing its job.
