does sound travel in space?does whatever we speak goes into the space and remains there forever?

Sound does not travel in space. \n\nSound is created when a vibrating object (your vocal cords, a guitar string, etc.) causes the air around it to vibrate. This vibration continues to expand outwards through the air (or water if you happen to be under water) until it reaches your ear drum, which in turn vibrates. Your brain interprets these vibrations as sound.\n\nSound does not travel in space because space is a vacuum. There is nothing to vibrate. So, when the vibrations (sound) reaches the upper levels of our atmosphere, it stops.\n\nSound does travel in the space shuttle because the space shuttle is pressurized and contains air that the astronauts breath. The air provides the medium to transfer the vibrations from the source object to the astronaut's ears.

Great question!  Space goes on forever - outwards.  HOWEVER, we don't think of ourselves as being "in space" while we are on Earth, so we could argue that there is a distance around the earth that, for the purposes of colloquial conversation, is not space.  Where does earth end and space begin?  Maybe at the minimum height for an unpowered stable orbit?

No, it doesn't damage the voice box...it has a different density, thus sound travels faster in helium

No...there needs to be a medium for sound to travel through, considering the Big Bang was the beginning, there would be no 'ether' for any sound waves. Just as we cannot hear any of the large energy bursts from the sun which occur everyday.

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.

YES\n\nSince sound waves are mechanical waves they are influenced by the medium in which they travel. But electromagnetic waves such as light and radio waves remain unafftected.

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.

Sound is a compressional wave and it requires atoms to make energy travel through. think of a pool stick being your mouth. being on earth is the same as having pool balls in front of it therefor the nergy is transferred. however in space, think of your pool stick without any pool balls in front of your stick. nothing happens. becuase there is nothing to transfer the energy. the medium is the matter that carries the sound waves.\n\nLight is a very special wave. it has tiny particles called photons that are infinity small(meaning we can't measure them but we know they are there becuase they ionize special elements.) so light is really a combination of energy and matter. and since light has a medium(tiny particles) within itself it doesn't need any other matter to travel. it can change mediums however, light travels faster in less dense areas than more dense areas which explains that is has tiny particles. sound is just a compressional wave which means when the matter is more dense it travels faster becuase the time required to travel is less becuase the molecules are closer. since light has its own molecules it can't travel through dense matter becuase the dense molecules block the light's particles from traveling.

It depends on which space you are referring to. Common people refer to space as the void in which everything else is contained. This space is infinite.\n\nScientists commonly think of space as a fabric acting like a balloon which is being blown into and expanding. At a given moment, this three-dimensional space of our universe is finite (having an end), although two-dimensional travel through space fabric is thought to be curved (and therefore endless). This balloon that scientists refer to as our universe containing what they call space is defined as being one of many universes moving in a larger multiverse. This multiverse is very similar to what most people would call space and may well be endless.\n\nIn sum, lay space never ends, but scientific space does.

condensed molecules are tightly packed so the sound wave vibration goes from each one in a quick succession.\n\nBTW, sound travels farthest in water! it travels cleanest in air

To hear a noise you need to have something for the noise to propagate through. The sun and Mercury exist in the vacuum of space. There is nothing in a vacuum, hence no sound can travel. So no, we can't hear the noise the sun or mercury make. Sound won't travel through the vacuum of space.\n\nBut the sun certainly makes a noise, it is after all a massive fusion reactor. If you could stand within the atmosphere of the sun without being vaporised or crushed you would be deafened by the noise it makes.\n\nBut once you left the Sun's atmosphere the noise would stop. All of space is a vacuum and totally silent.

No.\nNot even space itself, in which "entities" exist, is stationary -- it's continually expanding, carrying along those things that are in it.\nMotion is the rule in the universe, nothing stands still.

Sound travels in waves like light or heat does, but unlike them, sound travels by making molecules vibrate. So, in order for sound to travel, there has to be something with molecules for it to travel through. On Earth, sound travels to your ears by vibrating air molecules. In deep space, the large empty areas between stars and planets, there are no molecules to vibrate. There is no sound there.

Opinion. Indications are that it's both. There are few truly continuous things, but there seem, emphasis on seem, to be some. Light, for example is continuous....but it's also discrete. It behaves and a wave and as a particle. But as a wave it can travel through a vaccumn, which means there are no supporting particles to transmit it, and thus it varies continuously with no discrete intervals. To explain further; sound for example, is a wave, but it must travel via a media ( gas((air)), liquid, solid) which is made up of particles, and thus sound waves are actually discrete, while light doesn't seem to be. Light is involved in some ways with time. Speed, which is travel/time, at speeds approaching light speed, will vary perceptions of time, or for practical purposes, the passage of time. Very complicated question, not to be answered by me for sure, and evading our best minds in physics and philosophy. Finally, does it mater? I mean, if there are intervals, is reality dependant on time for it's existence? And if so, would it, and we, cease to be during intervals in time...so that nothing could happen then, and we would never be ever to sense or measure these intervals, or be affected by them. So for us time is continuous, unlike river flow and the sound of music.

in waves, therefore, in order to be transmitted it requires some medium to transmit the waves in. That's why sound can't travel through a vacuum such as outer space, for example

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!

actually, there may be something in the nothingness of a vacuum....\n\nwell,, sound (waves) needs a medium for it to travel...\nmedium like solids and fluids...\nsound (waves) cannot travel in a vacuum..\nthere's nothing in a vacuum...\nthat's why there's no sound...\nno pressure is created by the sound waves...\nthst's why there's no sound...
