How do black holes form and what are their properties?

A black hole is like a super strong vacuum cleaner that lives in space and can swallow everything around it.

Imagine you have a giant ball of stuff, maybe like a huge jelly bean, and it gets squeezed and squeezed until it becomes really, really tiny. That’s what happens to a star when it runs out of fuel. If the star is big enough, it collapses in on itself with such force that nothing can escape from it not even light!

A black hole forms when a star explodes or collapses. Think of it like a giant balloon popping, suddenly everything gets pulled inward.

If the star was really heavy, it becomes a black hole. It’s so dense and strong that nothing can come out once it goes in.

A black hole is invisible because light cannot escape from it. But you can tell it's there by how it affects things around it, like when something gets sucked in, or when space itself bends around it.

It’s like a really strong gravity that never lets go!
