What Is a Black Hole — And Why Does It Suck Everything In?

A black hole is like a cosmic vacuum cleaner. Imagine you drop a ball into a really deep well, the deeper it goes, the stronger gravity pulls it in. A black hole works like that but super strong: it’s so dense and heavy that even light can’t escape once it gets too close. The point where nothing comes back is called the event horizon. Scientists think there might be something called a singularity at its center, a place where everything becomes infinitely small and hot.
