Episode 3 Brain Freeze

.

BELL RINGS

-30 seconds to air, everybody!

-Wow!

It takes 26,000 years for light to reach us

from the centre of the Milky Way.

Yes, but what about Professor McCork?

Is he ever going to reach us?

He'll make it, Colin. He always makes it.

WHIRRING Whoa...!

Ow!

Oh, crumpets! The boss is going to be very angry.

Argh!

Oh, lads, you're not going to believe what I just saw.

Positions, everyone, we're going live!

This is Brain Freeze.

With Dr Knowles...

..Professor McCork...

and Colin, the...floor manager.

Stand by!

Hello, everyone, and welcome to Brain Freeze.

And let's reveal...

Today we're asking, do aliens exist?

And, luckily, I've got the answer right here on my ph...

Hush, Professor, we're live!

Now, the universe is a really, really, really big place.

There are eight planets in our solar system,

-which orbit our nearest star, the sun.

-Sure, we all know that.

The sun itself is one of 300 billion stars in our galaxy, the Milky Way.

Whoa, that IS a lot of stars.

And there are hundreds of billions of galaxies in the visible universe.

Hundreds of...billions...wha...? HE SIGHS

Actually, Professor, if you tried counting up every grain of sand

on every beach in the entire world,

it still wouldn't add up to the amount of stars in the universe.

Professor? Professor!

Ahem. Before we talk aliens, I think we need to take a break.

-BELL RINGS

-And we're clear!

-Are you all right, McCork?

-Aye, I'm grand, it's just a bump.

Hey, do you want to see a video I took of an alien?

Alien?!

You've seen an alien?

Here, take a look at this.

# La la la, da ba ba

# Ba ba ba, diddley-oh, hey! #

Oh, no, no, that's not the one. Hang on.

HE WHISTLES

Agh, that's not the one either.

Hang on, Colin, I'll get it. BELL RINGS

Oh, hurry up, McCork! We could get in big trouble.

-HEADSET WHINES

-Oh! Yes, boss.

Absolutely, yeah. Right away. And we're back!

I must have been dreaming it all up.

There's no such thing as aliens.

Kelly just got in touch to ask, "But are we really alone?"

Course we're not alone.

Colin's over there, look.

Huh? Ohh...

Let's look at how alien life could exist.

Humans survive on Earth because of a few basic ingredients. These are...

liquid water,

some key elements like hydrogen, oxygen and carbon,

a source of energy, the moon's pull on the ocean tides,

and an environment which keeps us warm and shields us from danger.

So, what you're saying is, we're just really lucky?

Well, possibly, but remember the scale of the universe?

You mean the grains of sand on the beach bit?

-Yes.

-Urgh...

-Everything all right, there, Professor?

I'm fine! I'm OK. Carry on.

Well, there's a good chance other worlds like ours exist,

we just have no proof they actually support life... Yet.

Yeah, but what are we going to do about it?

Well, Professor, we've got huge telescopes like Hubble scanning

the stars and sending us back detailed images of the universe.

Meanwhile, the twin Voyager spacecrafts

explore the outer reaches of our solar system and beyond.

So, although no evidence of extraterrestrial life exists...

-The search is definitely on.

-See you next time, folks.

And...we're...clear!

-Great show, everybody.

-Right, so. No rest for the wicked.

I'm off out to buy a telescope.

Good luck, lads. See you later.

But, McCork...you forgot your phone!

'Wahey!'

Come on, faster, faster!

This is way better than my car at home. Can't do anything like this.

-'Faster, faster!'

-Dr Knowles...

I think there's something you should see.

'Can I drive?'
