Detailed Solution

The above statement is false.
A sound wave is a longitudinal wave. The sound can be transmitted only through a medium, so we cannot hear a supernova in space. We cannot hear any sounds in the near-empty regions of space. Sound travels only through the vibration of atoms and molecules in a medium such as air medium or water medium. Light does not require a medium to travel through, whereas sound does and thus cannot be transmitted through space. That is why we can see supernova explosions but not hear them.
The correct statement would be we cannot hear the sound of a supernova explosion taking place in outer space
