sound wave in space ??!?

What happens to the energy being carried by sound wave in space.does it die out ? if yes , so the energy is not constant in space????!!

    space is not a perfect vacuum, thusly sound can move, but not like it does on earth

    it has about 20 thousand atoms of hydrogen and helium every cubic inch

    if one gets hit with a vibration, it bounces and eventually will hit another and so on.

    (newtons 3rd law For every action there is an equal and opposite reaction. _especially in space_)

    sounds become VERY muffled in space and because the atoms are so spread apart, the speed of sound drops dramatically as well.

    not only does the speed drop, but the freq at which it is transmitted drops too, giving you much lower tones.

    most sounds in space are still there, but their freq is below that of which human ears are designed to hear.

    I think scientists found a b flat coming from a black hole?

    "Collectively, the cosmos produce, scientists believe, a cacophonic symphony of inaudible tunes."

    "Chandra observations revealed a note that is more than a million billion times deeper than what you can hear."

    "No human will actually hear the note, because it is 57 octaves below the keys in the middle of a piano."

    the b flat was picked up in space, by a satellite, the Chandra X-ray Observatory

    Light isn't strictly a wave, although it behaves like one in certain circumstances. But light is really a stream of particles called photons. Photons (and all particles) can travel through space very easily since there are so few things they can collide with. But sound is truly a wave. It is caused by the compression and rarifaction (squeezing together and pulling apart) of matter. So sound travels fastest and most clearly through solids because the molecules are very close to each other. The energy of the wave is transmitted more completely and accurately. The atoms always have another nearby atom to transfer the kinetic energy (motion) to. Sound waves travel through water pretty well, but not as well as in solids because the atoms are farther apart. Some of the sound wave's energy is lost when atoms don't run into other atoms as quickly or often. Sound waves travel through air poorly compared to liquids and solids. The atoms in air are spaced apart much more than in liquids, so more energy is lost more quickly, severely limiting the distance a sound can travel. Sound doesn't travel in space because there are almost no atoms to collide, so no waves can be created.

    Waves are disturbances in a medium. These disturbances will cause a force to move ,the particular motion of a force is a wave.Hence there must exist in space a medium of a particular substance that would be responsible for the wave phenomenon.

    In Space the gravitation Power is not homogeneous.

    It Conforms to different gravitational Power levels.

    Therefore in Space there must exist Gravity waves of various frequencies.

    However because of the range of frequencies that our ears can respond is not within the range of a Gravity wave; thus we cannot hear it.

    On Earth disturbances in a gas liquid or solid will cause different motion of sound at different velocities and frequencies.Our ears only responds to only a certain range of frequencies. Animals have different range of frequency of audible range.

    In order for a wave to exist and propagate a medium needs to exist.The Density of the medium determines the velocity of its propagation.Thus Gravity waves velocities are a function of the space power level densities.

    First is that sound waves are pressure waves (and not transverse )u can hear sound because of the changes in the air pressure u have created ............

    Now the thing is sound wave cannot be generated in the space suppose that u have generated the sound say by u r mouth only u can hear it bcoz u r medium ..........

    or either u send a sound wave (not a radio wave) it returns back to earth i mean it will be oscillating in the atmosphere of the earth but cannot cross the border of our atmosphere ...... like u hit a ball on the wall it returns back to u.......

    k........ now for the last if u some how create a pressure say by u r mouth and say a has to travel in space the pressure that u have generated by he gas u hav released converts in their kinetic energy of those molecules..

    hope u got it...........

    Sound does just not propagate in space. If you have a noise rocket engine turbine, the energy is not transmitted into space, but instead keeps on being reflected through the spacecraft structure in form of vibrations.

    There is no atmosphere to vibrate in space. Sound must have atmosphere to propagate.

    does not travells if it travells means there is a lot of sound pollution and we can discover many things.
