A black hole is formed when a massive star dies and collapses down into a very compact object.

It’s called a Black Hole because it’s invisible in space; it gives off no rays of light.

Its force of gravity is so great that nothing can ever escape: neither matter nor light.

But how does a black hole trap light?

When you throw a ball into the air, it always ends up falling back down because of gravity which attracts it to the center of our planet.

To escape Earth’s gravity, you would have to throw the ball at a speed of over 40,000 km an hour.

The more massive a star is, the more speed you need to escape its gravity.

A black hole is so massive that to escape from it, you’d have to go faster than the speed of light.
