Can You Hear Sound in Space?
About | Information | History | Online | Facts | Discovery
If space is a vacuum, is it possible to hear sound in it? Trace is here to discuss why sound travels differently in space. Read More: What is a vacuum?

Okay, so you proved you can not hear sound waves while in space, but that doesn't mean sound waves are not traveling through space until they come in contact with a mass that can turn the waves into sound correct? If the sound waves do not have interference then it should travel freely.. Just like the example given about being on another planet. If the planet is more dense then the volume seems deeper. I am sure this means the waves are not going to travel as far as well. So if you were able to yell in space, I believe the sound waves will travel until they reach a mass dense enough to create sound.

Why would your voice deepen on Venus. The speed of sound is very fast so the resonance in your vocal cavity should support a higher timbre not lower. Also, I'm pretty sure the main reason for the higher speed of sound on Venus is the higher temperature more so than any "soupiness"

if witnesses report that ufo has no sound while flying above them, maybe ufo engines do make sound, but ufo has some sort of vacuum field around it and sound cant pass...

haha cody proved you wrong. check out cody's lab.

THE SIMPLE ANSWER IS RADIO FREQUENCY

In order to create a vacuum there has to be an applied negative pressure within a chamber! Well that,s how it is on Earth as I understand it! At first it seems therefor that in theory our universe must be within a chamber of some sort under negative pressure! But when you think about it here on Earth we live in a positive atmosphere in comparison with a constant pressure ! So it would seem that within the vacuum of space that there must be some application at work applying pressure to the planet against the vacuum of space like pumping up a football for instance but of course the earth has no outer membrane also therefor if you pumped air in it should just drift off into space! We know that gravity takes care of that issue and that,s not so hard to get your head around! It still leaves the mystery of the space vacuum and how it works! So I,m now asking myself if we have positive pressure here on Earth and negative pressure in space then, What is neutral pressure ? How is it possible to quantify neutral pressure where there are no benchmarks? Thought of the day ! Before the big bang was space pressurized and has someone just pulled out the cork to decompress the universe and create the big bang? Answers on a postcard!

Light and radiation

I am posting this guys question and my reply up here at the top in hope that some people will read both and comment.
from Din telalovic:
"maybe a silly question..But, if you'd be close enough to a exploding
super nova and wouldn't die. Would you hear it explode? Because with the
explosion a large amount of energy en matter is super rapidly expanded
outward thus compressing atoms together making way for sound to jump
from atom to atom."
from me:
What a great question! If you have not seen it already, direct imaging
was done of atoms and published in Nature. They basically looked just
like the spinning tops modeled by orbital physics. If the atoms and
particles (neutrinos, radiation) are actually striking your ship, then
contact and vibration are occurring. Some "particles" and radiation may
just slip through, of course. The point is the lack of atomic substance
in "space" itself.
Who is to say, though, that something isn't perturbable at the vacuum
flux level (if you know what that is...)? There are very well known
models which suggest that the medium of space itself functions as an
unknown fluid (space-time fluid).
That would require some sort of extreme amplification for us to hear
though.
Do you know the bowling ball and feather test? Even on Earth, in an
artificial vacuum tower,
a bowling ball and feather land from a drop at the same time, regardless of what we call "weight"...
The same "silence" occurs in a vacuum on Earth.
Radio waves DO transfer through the vacuum and DO excite "sound" across
it.
What's a radio wave then? Is the medium waving like sound, but
differently? -
You can hear in space if you are in a small spaceship that has oxygen which would make sound travel and vibrate into your object(spaceship). You cant hear in space if you are just outside. So like you said, you can hear if you are inside a suite or something that has air in space.
-
"waves can't move thru space" what about light waves or gravitational waves?? or do light waves travel as a particle in space?
-
Sound can't travel in a vacuum but a rocket can? Lmao at everyone who believes in this
-
mybe a silly question..But, if you'd be close enough to a exploding super nova and wouldn't die. Would you hear it explode? Because with the explosion a large amount of energy en matter is super rapidly expanded outward thus compressing atoms together making way for sound to jump from atom to atom.

Mcree HAVE the play of the game !!

electromagnetic waves.
-
Idiot there's sound in space it's just so quiet you can't hear it and there is air in space but it is a gas so it spreads out so by now all the molecules would be separated so far apart
-
Hitting your head against the ceramic tiling of the Space Shuttle Thermal Protection System I think guys inside should be able to hear you since the vibrations that you produce still would vibrate the atoms inside for them to year, though extremely minuscule...

I'm here because of Infinite warfare...

Use laser as a medium!
-
Everyone knows that Star Wars was a long long time ago when the universe had not expanded and space was still dense enough to hear explosions in space. Quit whining :-)

My nearly 9 year old son has a question, maybe that has an answer to your question too! We know sound needs matter to travel.Thought light doesn't. Light is an electromagnetic wave. Can sound use light as a medium to travel? It that a possibility ever? Can sound be converted to EM waves or superimposed on EM waves and be made to travel that way?
