If the Moon exploded, would we hear it?

Basically no. You need some kind of medium to propagate sound and there's too much vacuum between the moon and us.


The moon itself has a 'atmosphere' of density roughly #10^(-14)# times the density of Earth's atmosphere at sea level (Wikipedia "Atmosphere of the Moon").

The space between the moon and the Earth's atmosphere has even fewer particles.

What we might hear is the exploding of fragments of the moon as they collide with our atmosphere.
