Contrary to some comments, space IS NOT a vacuum. Forgetting about quantum issues, such as fields, etc., space has a density of approximately 5 hydrogen atoms per cubic centimetre. At this density, any energy put into an atom would not be sufficient to be transferred to another - the atoms are too far apart to transfer the energy of sound. The denser the medium that sound energy is added to, the quicker the sound will travel.

Sound is the transfer of vibrations at a given frequency from one object to another. Sound waves travel through matter (air, water, etc) to reach the eardrum, where the vibrations are interpreted as audible sound to our brain if they are in the right frequency (20 Hz to 20kHz for most humans) and at audible decibels.
In space, there is no matter to transfer the sound waves, thus sound cannot travel through space.
Hope this helps!

Because sound needs air to push the wave along on its frequency. When in space it is like being in a vacumn. So the sound has no resistance against which to travel its logical path on it soundwave.

Sound requires a medium (like air) to bounce off the waves. Space is a vacuum, and therefore there is nothing to bounce the sound waves off of.

Sound is just a vibration of molecules. In a vacuum there are no molecules to vibrate. Space being a vacuum.

sound is a percusive wave, it requires a medium to travel in.
here on earth it travels in air or in water or rock.
but in space there is no air for the sound to travel in. thus no sound.
