If you shout in the direction of space will your voice get picked up by a space traveller in the future?

Sound needs a medium to travel such as air or water. Since there are no air molecules in space, sound can not travel. This is demonstrated when you sound a tune fork inside a closed bottle and then suck the air out of the bottle. The tune fork will vibrate to eternity since the air molecules are not there to create friction, but you will not hear any sound coming from it.\n\nIt would have been nice if it was like that. You can shout your name and it echoes in the heavens for eternity. But, alas, that is not so.

Compared to Krakatoa, the space shuttle would appear to be a point source of sound energy.  The "inverse square law" does not work for a wall of sound or a wall of light or even for a wall of radiation compared to point sources.  Gravity exhibits compliance with the inverse square law only if you consider mass to be concentrated at a point for calculations.  For example the earliest land surveys of northern India contained original significant errors because the attraction of Mt. Everest for the surveyor's plumb bob was neglected.  The loudest observed sound that I have read of was the blast from a Saturn rocket in which the sound was so intense that the condensations were separated by rarefactions that approached a pure vacuum.  You needed distance and ear protection but it was not even heard in upper New York state!

The sound will reach the car in front of you.  Although it may seem as though it would not, considering that you are already traveling at the speed of sound, therefore you may think the sound waves go as the same speed as your car therefore not traveling any faster than you are and not getting to the car in front of you.  However, this is not the case.  This can be explained using Einstein's theory of relativity.  Einstein describes "frames of reference" and in your frame of reference, you are not moving; everything else is moving.  Everything in your car is stationary relative to everything else, this is why you don't feel like you're moving, and if you throw a book sideways, it doesn't fly backwards with the speed your vehicle is moving, this is because the car, yourself, and the book are all moving with the same speed your car is moving. They are all stationary relative to each other. When the sound waves are created, they move in all directions at the speed of sound (331 m/s), so in your frame of reference, they would be moving at 331 m/s away from the car in all directions.  This means from the frame of reference of a person standing outside of your car, the sound waves would actually appear to be moving at twice the speed of sound.  This is just like if you threw a ball forward out from the car at 15 m/s, it would appear to an outsider to be moving at that speed plus the speed of sound(well in a vacuum anyway, or before air resistance took over) To use a better example of these frames of reference, you know that the earth is rotating.  It is rotating at 1070 mi/hr at the equator, yet it seems not to be moving at all, it is our frame of reference when we are standing 'still.' the speed of sound is no different traveling in different directions on the earth because of this rotation.\n\nand yes, he would probably give you the finger. I mean, he is going at the speed of sound, how impatient are you?

It won't make you run any faster, but will make your voice sound funny.

If they were close enough to hear it.Yes...if not...no sound is made....sound consists of a transmitter (tree) and a receiver (ears) if one is missing then its not sound.\n\nGood Luck

Is the person next to you moving at the same speed as you?  If so you'll hear him fine.  If he's not moving at all then you'll never hear him, as the sound can't catch up to you.\n\nImagine another scenario to understand what I mean.  You're on an airplane which is stationary (say it's parked at the loading gate) and you're running down the corridor of the plane.  You can reach a maximum speed of 30 km/h.  Now, if the plane is moving at 300 km/h and you're running up the corridor, you're moving effectively at 330 km/h.  It's the same with the sound coming from your mouth.  If you're moving at a speed of X, when the sound comes out of your mouth, it's moving at a speed of X + roughly 350 m/s (the speed of sound).

They can do it, but it usually depends on the function of the vocalization in particular.\nAs others have stated, vocalizations that help group communication (as in flocks flying together) or prey location (as in owls) are emited during flight. \nSome epigamic (reproductive) displays also involve singing while flying, but many songs of male birds are emited from a perch. These may be addressed at other males (territorial) or at females (advertising calls).

Sound needs a physical medium (like air or water) to travel through, so if you're talking about sound traveling through space, that's a no-go.  Electromagnetic waves, yes - light, x-rays, gamma rays, and so on.  Sound waves, no.  As far as here on Earth, I don't think that would work either.  The intensity of the sound wave would diminish very rapidly - eventually the vibration would be smaller than an atom, and be lost in the craziness of the molecular world.\n\nHowever, some of the stars that we see are in fact millions of light years away.  So that light has been traveling for millions of years.

The previous poster is right.  It's particles in the air "vibrating" (caused by pressure differences) that enables you to hear.  That is why in space, which is a vaccuum, you cannot hear anything.  There is nothing to transmit those pressure differences to your ear.

only in space where there is no air\n\nof  course there no clouds either but electrical spark can still be produced artificially\n\nedit: "a mile away for every second counted: -- make this about 4-5 seconds; the sound speed is about 300m/s

The voice is the instrument of communication.

It would probably sound something like this:\n\n"AAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHH"\n\nsince we'd all just fly off the surface of the Earth and shoot into space.

Not neccessarily.  But it is not because the sound waves are being affected by gravity.  It is because the medium that the sound travels through is affected by gravity.  The air is thicker at the 1st floor and thinner at the 10th floor.  To make an extreme example it would be like passing sound through water at the 1st floor and air at the 10th.  So yes it will be different sounds but because of the effect of gravity on the medium not the waves.

Of course, but two things. You will definitely get hit with some heavy duty roaming charges but the good news is since the round trip for a signal to get here and return is about 4.4 billion years you can probably duck out on the charge since you'll be dead.
