What is a Black Hole?

A black hole is a place in space where gravity is super strong. Gravity is the force that pulls things toward each other, like how the Earth pulls us so we don't float away.

In a black hole, the gravity is so strong that nothing, not even light, can escape from it. That’s why it’s called a 'black' hole — because no light comes out, so it looks completely dark.

How Do Black Holes Form?

Black holes usually form when a big star runs out of fuel and can't shine anymore. The star then falls in on itself because of gravity, becoming smaller and smaller until all its matter is squeezed into a very tiny spot called a singularity.

Around this tiny spot is a boundary called the event horizon. Once something crosses this boundary, it can’t get out.

Why Are Black Holes Important?

Black holes teach scientists a lot about space, gravity, and how stars live and die. Even though black holes seem mysterious and scary, they help us understand the universe better.

Fun Fact!

Black holes can be big or small. Some are tiny, and others can be millions or billions of times heavier than our Sun!
