Noise traveling through space?

In movies when you see a space ship flying it always has some cool sound to it. but isnt it true that in reality you wouldnt hear nothing in space.
I dont know the actual science about this but wouldn't that make it pointless to listen to sound waves from distant planets or whatever NASA tries to do.
Or is it that they travel but while in space you can't hear them but like a place like earth lets say you would be able to hear the sound you werent able to in space?
I dont know I can't sleep at night thinking about this ; )
 
NASA doesn't listen to sound from other planets. That's ridiculous. They observe light, and other types of radiation emitted from stars.
 
They emit pressure waves but without a medium to compress, no sound is made. But if you put a receiver you can interpret teh pressure waves as sound again. I think that's how it works.
 
sound needs a medium to compress.

vacuum = no sound.

Yah know, I remember this from 2'nd grade science. WTF is wrong with our school system?
 
I thought sound travels through sapce. sputnik confirmed that right? in a no matter enviroment like space you wont be able to hear it but it will be transmitted. so matter/makes sound--->transmits through space--->matter(such as air in helmet)--->ear will hear it as sound.

what is sound exactly? isn't it a disturbance of air at a certain frequency that vibrates your ear drums?

 
So if two people about 10 feet apart yelled at each other in space (without the bubble head thing) they wouldn't hear each other at all? I find that hard to believe.

I think if they took off their helmet in space their head would explode cause of the pressue 🙂
Just my guess anyways im no scientist

OK assuming that they won't explode (implode??), wouldn't they hear SOMETHING??

right

em wave needs no medium to travel (as far as current theories go anyway) but sound wave does

Not unless they are touching somehow. If there is something to transmit the vibrations (touching, through the ground...) But it won't go through the air.

regardless, the wetness of the fart would still make first contact
 
This just inspired another question:

If you had a room, a sealed off, air filled room (ie. your normal office) and you had it surrounded by another room, which is a "vacuum".. Would the room inside the vacuumed room be soundproof from any outside noise?

I'm thinking a different way, as in.. there is a room, and there is another thin 1-inch wall that is a vacuum on the inside. But it's not actually touching the middle room, its more or less just surrounding it. Get me?

That is correct.

sound cannot travel through a vacuum. Nothing to compress/decompress. sound is a longitudinal (sp?) wave.

well wouldnt sound waves have to travel considering that we can talk to the space ships out there?

Thats called a radio.

I got a question, how old are you and where are you going to school?
