does sound have to travel through something to make noise, like air or water? can it travel in space?

PLEASE TELL ME

YES - Sound needs a medium to travel through.
Hence the tagline for Alien (the movie) "in space no one can hear you scream"

Light does not need a medium.

Sound needs a medium to make noise. Because space is essentially a vacuum, sound can't travel through it.

Yes, sound does need a media like air or water to propagate, in space there is the vacuum, so if an astronaut speaks to another astronaut without a radio they won´t listen each other.

Yes, so know that every space movie you've ever seen had the fundamental flaw of a ship loudly exploding.

The sound is made by the particles colliding to one another.

Since there is no air in the space, the sound can not be made, because there is no air particles to "make" the sound.

There are no sounds in space...But sound waves are created. So that means that if there was no sound in space and something really big exploded close to us, we would not be aware until the waves of sound hit our atmosphere.

No, it can't but you can always do lip reading. light can travel through space.

Is there really sound in space?

Actually...yes!!

What is sound? It is a pressure wave. So long as you have some kind of gaseous medium, you will have the possibility of forming pressure waves in it by 'shocking' it in some way.

In space, the interplanetary medium is a very dilute gas at a density of about 10 atoms per cubic centimeter, and the speed of sound in this medium is about 300 kilometers/sec. Typical disturbances due to solar storms and 'magneto-sonic turbulence' at the earth's magnetopause have scales of hundreds of kilometers, so the acoustic wavelengths are enormous. Human ears would never hear them, but we can technologically detect these pressure changes and play them back for our ears to hear by electronically compressing them.
