of all the cool sounds I've heard
while traveling in outer space.
Like the raging storm of Jupiter's Red Spot!

Of course there are. - Yeah!

- No, that's just what you Earthies call a "joke."
Just like you saying there's no sound in space!

Real space isn't like a comic or a science fiction movie.
It's silent. - [laughs]

We may have solved one sound mystery,

We need to find out for sure if there are sounds in space.

Come on, let's go see Dr. Mom!

- I am so glad you kids came by,
'cause the "are there sounds in space" question
is one of my all-time favorites.
- Mine too. Especially since I already know the answer.
- So do I!
- And before we get to the answer,
let's start with the basics.
Did you know that sounds are a type of wave?
- You mean like an ocean wave?
- They're similar, but sound waves
are waves that we cannot see.
- Well, if we can't see them,
then how do we know they're really there?
- Ah! Because we can hear them.
But in order to hear sound waves,
they need something to travel through,
like air or something solid, or even water.
[dolphins clicking]
Okay, wow.
[chuckles] Thanks for the help, Sunspot.
You sure are well-trained.
- Actually, he's just super smart,
as are all Bortronian pets.
- Bortronian pets?
- Yeah, you know, from Bortron !
- Jet's, um, just pretending, Dr. R.
- Oh. [chuckles] - Yeah, that's right.
There's nothing unusual about him at all.
Sunspot's just a regular Earth...
- [chirping] - Uh...animal!
- Mm-hmm, except that he's unusually talented.
- So! How about a little sound demonstration, Mom?
- [chuckles] Great idea, Sean.
Uh...oh! You can start with this kitchen timer.
[timer ticking]
Can you hear it? - Yes!
Because sound waves are traveling through the air.
- That's right, Sydney!
Now take the timer to the other side of that door.
[timer ticking]
- Oh, I can hear it!
Because the sound waves are traveling
through something solid: the door.
- Correct, Jet! Now let's see
if we can hear the timer ticking
under the water.
[splashes]
[timer ticking] - Yup, loud and clear.
- And I can see it too! The water's moving.
Wow, sounds waves can travel through all sorts of things.
- So that must be true in outer space too!
- Actually, Jet, there is no sound in outer space.
- Yes! - Aww.
- [chuckles] Because it's very, very empty,
so there's nothing for the sound waves
to travel through.
We call this a vacuum.
- Um...you mean like the vacuum my dad uses to clean the rug?
- Or--or the one my mom uses to clean the front lawn?
- [chuckles] No, this kind of vacuum means
a place where there is no air.
- So if you're an astronaut
floating in front of some big expl*si*n
like two asteroids colliding,
you wouldn't hear a thing?
- That's right.
both: No way!
- [chuckles] I know it's hard to believe,
but it's true.
I hope that answers your question.
- It sure does! Thanks, Dr. Mom.

but I still think I heard space sounds.

are just pretend, I know she has actual science in them.

go to outer space and test our hypothesis.
- Did someone say "go to outer space"?
- That's right! I did.
[both gasp] - Wait a sec.
You actually want to go to space, Sean?
- Going to space is the only way to prove
