Because waves, such as sound, need to travel through a medium, whether it be water, air, etc. Since in empty space, there is no air, therefore there is no medium to travel in, so sound cannot travel.
Sound waves require a medium (solid, liquid or gas) to travel through. They do this by alternately compressing and rarifying the distanced between the atoms or molecules of the medium.
Sound, which is mechanical energy, can travel through solids, liquids and gases. It can also travel through plasma if it has the chance to. It must have a medium; it cannot travel through a vacuum. Pretty much everything else is fair game, and the effectiveness of the medium at conducting sound varies widely, but, in general, sound travels fastest through solids, not as fast through liquids, and more slowly (relatively) through gases.

sound can travel through sound waves in the air which cannot be seen to communicate with each other
Sound waves require a medium (solid, liquid or gas) to travel through. They do this by alternately compressing and rarifying the distanced between the atoms or molecules of the medium.
Light waves travel at approx 300,000 kilometres per second, sound at approx 0.343 kilometres/second.Light waves can travel in vacuum or through some media (there is no such word as mediums!). Sound waves cannot travel through vacuum: they needs a physical medium.
Sound waves cannot travel through space.
