Ground Control to Mission One, do you read me? Come in, please.

0:00:030:00:07

Mission One to Ground Control. Receiving you, loud and clear.

0:00:070:00:11

Prepare to engage transmission.

0:00:110:00:13

Oh, and, by the way, Dr Knowles, where on earth is McCork?

0:00:150:00:19

That's the thing, Colin, I'm not on earth at all.

0:00:190:00:22

I'm in space!

0:00:220:00:24

Wow!

0:00:250:00:27

And we're live from space in ten, nine, eight, seven...

0:00:270:00:31

This is Brain Freeze,

0:00:310:00:34

with...

0:00:340:00:35

Stand by!

0:00:440:00:47

Three, two, one. It's time for...

0:00:490:00:53

Welcome to Brain Freeze, in space!

0:00:560:00:59

Today, we're asking...

0:00:590:01:00

To understand black holes, we first need to talk about gravity.

0:01:020:01:06

Every object exerts a gravitational pull on every other

0:01:060:01:09

and the larger the mass of the object, the stronger the pull.

0:01:090:01:13

We're all familiar with gravity on Earth -

0:01:130:01:16

it's what keeps us from floating away.

0:01:160:01:18

What goes up must come down!

0:01:180:01:21

In space, these gravitational forces keep the moon orbiting the earth

0:01:220:01:27

and the planets orbiting the sun.

0:01:270:01:29

So, what would it be like without gravity, Dr Knowles?

0:01:300:01:33

Let's find out!

0:01:330:01:34

Ah! Ha-ha! This is brilliant!

0:01:380:01:41

To find out what all this has to do with black holes,

0:01:410:01:43

join us after this break.

0:01:430:01:45

Show's going well, Dr Knowles. What's it like up there?

0:01:470:01:52

Oh, Colin, it's so beautiful!

0:01:520:01:55

Looking back at planet Earth is truly amazing.

0:01:550:01:59

Such a fragile world, so still, so silent, so perfect... Huh?

0:01:590:02:07

Hey, Doctor, look at the way my snot behaves in zero gravity! Ha!

0:02:070:02:12

Professor!

0:02:120:02:13

Ow! Stupid gravity.

0:02:140:02:17

Stand by in space - we're coming back to you live!

0:02:170:02:20

So, tell us, Dr Knowles, what is a black hole?

0:02:250:02:28

Black holes are not really holes at all.

0:02:280:02:30

In fact, they're the opposite of empty.

0:02:300:02:33

They're full and a black hole.

0:02:330:02:35

A black hole is an area of such immense gravity that nothing,

0:02:350:02:39

not even light, can escape from it.

0:02:390:02:42

Black holes form when a star collapses in on itself,

0:02:420:02:45

producing a massive explosion.

0:02:450:02:47

Boom!

0:02:470:02:49

All the material left over is thought to have

0:02:490:02:51

a mass of more than ten suns,

0:02:510:02:53

which gets squashed into a sphere roughly the size of New York City.

0:02:530:02:57

It's so small now and yet so big. I don't understand.

0:02:570:03:02

Imagine if the entire mass of the earth

0:03:020:03:04

was squashed down to the size of a fingernail.

0:03:040:03:07

That would be a lot of gravity.

0:03:070:03:10

It is! And that's why other, smaller objects

0:03:100:03:12

are pulled towards it and trapped inside.

0:03:120:03:15

Oh, I hope there are no black holes around here!

0:03:150:03:18

Not to worry, Professor -

0:03:180:03:19

the nearest one is hundreds of light years away.

0:03:190:03:22

I think we're pretty safe.

0:03:220:03:23

See you next time!

0:03:230:03:25

Brain Freeze from space - we are clear! Oh!

0:03:260:03:29

Ms...Ms Hucklebuck?

0:03:290:03:32

Ms Hucklebuck?!

0:03:320:03:34

MS HUCKLEBUCK SCREAMS

0:03:340:03:38

Erm... Dr Knowles?

0:03:390:03:42

What's that tiny dot, there?

0:03:420:03:44

You mean...the one heading straight for us?

0:03:440:03:47

-BOTH:

-Whoa!

0:03:590:04:00

Oh, hello there. Any chance of a lift home?

0:04:000:04:04

-This is nuts!

-Ha! She's bonkers, that one.
