Sound needs a media to propagate.
Sound can not propagate in a vacuum.
Sound waves, unlike light, are essentially compression waves and the
sound in order to move from one place to other needs molecules to
compress and decompress against, hence the wave is transmitted. In a
vacuum, there are no molecules. Hence no sound.

Sound needs a medium to travel, but light do not needs one. So Sound cannot travel in vaccum or space, but light can. So Light can travel in spave but not sound. So if supposing some explosion is there in the outer space, we can see that, but cannot hear the sound.

In a vacuum (in outer space). Sound needs air or some other relatively dense physical material in which to travel, light does not.

Sound needs something to travel through, wether it be dirt,air,water,or anything with particles,so the nearly empty vacuum of space is the only place where this happens.
