Detailed Solution

The reason why we can not hear the sound of a supernova explosion in space is that there is no medium to travel.
Sound is produced by the vibrations of the particles of matter. When an object vibrates, its particles transfer the energy to the neighbour particles without moving from its position. Since there is no atmosphere in space, sound propagation is impossible.
