-I'm Vivaan.

I'm 10 years old, and I live in India.

I'm a kid expert on black holes.

♪♪ So, basically, a star formed from a cloud of -- a cloud of hydrogen, and the hydrogen -- basically, it keeps fusing together to make energy.

And when it runs out of hydrogen to fuse, then it collapses in on itself.

And when it collapses in on itself, it creates an explosion.

And then it's turned into this -- into this thing which has so much gravity that not even light can escape from its pull.

That's why it's called a black hole.

To escape it, you'd have to be traveling faster than light.

[ Zip! ]

Basically, the gravity is so strong that it'll pull you into strings of spaghetti.

[ Creak! ]

[ Blink! ]

Inedible spaghetti.

It's actually called spagettification.

You won't survive.

Some can be bigger than the entire solar system.

Meaning, like, their diameter can be many times the distance between the sun and Pluto.

Stars which become black holes are enormous.

Slightly smaller than that, and they might make neutron stars.

And smaller than that, they make something called a white dwarf.

Black holes are really cool because they can help us learn about the mysteries of the universe, and they can tear apart a sun, and they can slow down time.

Isn't it just great to know about something which is this powerful and this potentially dangerous?
