Rotating black hole

Okay kiddo, do you know what a black hole is? It's a place in space where gravity is super, super strong. It's so strong that even light can't escape from it.

Now, imagine a black hole that is spinning like a top. Just like how spinning toys have certain things about them that change when they spin, a rotating black hole has some special features too.

One of the things you might notice is that the space around a rotating black hole gets twisted up in a spiral shape, kind of like how you twist a curly straw. This is because when the black hole spins, it kind of drags the space around it with it.

Another thing that happens is that time near a rotating black hole also gets twisted up. This means that time seems to move slower the closer you get to the black hole. So if you were watching someone getting closer and closer to the black hole, it would look like they were moving in slow-motion.

So, a rotating black hole is a super strong gravity space object that twists and warps space and time around it because of its spinning motion.
