Can you here in outer space?

Answer 1

No. Sound is distributed by the collision of molecules/atoms transferring energy to each other. Space or vacuum, by definition is completely empty, with no molecules to facilitate this transfer, and hence sound cannot propogate through space. The movie 'Alien' famously had the line 'In space, no one can hear you scream' or something along those lines

This answer is perfectly correct, but to those who do not (the very few) understand this text, this answer is, literally: In space or vaccum, sound does not travel because sound is transferred through cells, molecules/atoms, as you say, and there is nothing there, no cells or atoms or molecules, therefore the sound cannot be passed on. -.- that was absolutely pointless, but I'm currently, very, very bored.
Sound does not travel through a vacuum.
Sound requires a medium to travel thru. Since there is nothing in a vacuum, there are no particles to transmit the sound.

Answer 2

Sound waves travel through space only if the is some medium in that space. Space on Earth is filled with stuff (like air, water, rock, etc.) Sound cannot exist in empty space. Outer space is pretty empty.

Sound travels in waves by making molecules (or atoms) vibrate within the environment they are emitted (water/air). There must be some medium for the vibrations to travel through to stimulate the structures within your ears. Since there are no molecules to vibrate in outer space, sounds have no way to be transfered from the source of the sound. Even if "sound" could exist in space, we would not be able to "hear" it.

Sound is mechanical energy.Mechanical energy, generated by whatever means (a vibrating string, a hammer blow, a rock falling into water), travels in a medium. The actual energy is transferred into the medium in order to move away from the source. The medium actually carries the mechanical energy of the sound after it is "put into" that medium. If there is no medium into which to transfer the energy, the sound cannot exist. A string could vibrate in the vacuum of outer space, and the "source energy" would be there, but the energy would not "go anywhere" because of the lack of a medium.

Answer 3

No. Sound waves are transmitted by the physical vibrations of matter, and there is no matter to speak of beyond our atmosphere.

Oh yeah? What about dark matter? No-one knows whether sound would travel through outer space because it is impossible to test. Certainly, sound doesn't travel in a vacuum, but space is not a vacuum.

Answer 4

Yes, sound can travel if a normal atmosphere is present.

In a vacuum, however, such as in space, sound cannot travel, since there is no matter to be set into vibration.

Yes, it can--if that empty space is not a vacuum. It then has a rather high speed. But if that empty space IS a vacuum, then it blocks sound; so no in that case.
hi
It just depends on what you mean by empty space... if you mean a vacuum, as 'in space' then no. You hear things because an action, or an event which makes a noise causes a vibration which is passed through gases (air), water or solids. If someone was to shout across a room you would feel the vibration in the air as it hit your eardrum, this in turn vibrates your eardrum... these vibrations are interpreted as sound. Think about a whale calling to another whale... their song can be heard from miles away by other whales through the water. Sound travels better in water than in air, and better through a solid than water. This is because the molecules in water are denser than they are in air, and more dense in solids than either air or water... therefore there are more molecules to pass the vibrations on... it is conductedbetter. So in short, if there is nothing to conduct the vibrations then no sound is produced.
No. Sound wave are mechanical waves and therefore need a medium to travel through. Sound waves vibrate a medium and what we here are the vibrations. "Empty Space" is a vacuum with no medium for the sound waves to vibrate across and therefore there is nothing to hear in empty space because there is no vibrating medium.
Sound waves need some sort of median to travel through. Sound cannot travel in the complete vacuum of empty space.

Answer 5

Presumably not, since sound waves require a medium through which to travel. Of course, someone in a space vessel could conceivably hear an echo WITHIN THE SHIP, which would itself be "in space."

Answer 6

-- Two astronauts together in the same vessel or capsule that has air in it

can communicate by means of mouths and ears, in the usual way.

-- In any other situation or configuration ... two people without an air path

between them, or communication between anyone outside the atmosphere

and anyone in it ... radio is the only way to go.

Answer 7

we can't hear sound in outer space because space is a vacuum and it does not support sound radiation

Answer 8

NO!!!!

Sound waves need a medium to transmit.

The medium, can be gas, liquid, or solid. In space it is a vacuum, there is no matter, so no sound waves transmit.

Answer 9

Nothing. Sound is the vibration of our atmoshere's molecules - there is no atmoshere in space.

Answer 10

Sound is the transfer of energy through particles; there are no particles in a vacuum (space) so sound will not travel.
