Sound is just our perception of the waves travelling through air. Sound energy compresses air molecules together as it is transmitted. When the moving molecules hit our ear drums they make them vibrate and we detect this as noise. There's no air in space, so the gap between the moon to the earth (about a quarter million miles) is not able to transmit noise.
However, the atmosphere of earth does have air, so if the explosion was BIG enough, and there was enough energy left by the time the shockwave reached earth, that energy would be converted to sound in our atmosphere.

Atmospheric sound waves are propagated by compressions of air molecules. In the vacuum of space, there is no matter which can allow sound waves to spread out from an origin. However, the massive force generate by the blast, and also the debris, as someone here mentioned, will cause the molecules in our atmosphere to vibrate and therefore produce sound. So it is highly likely that we would hear something like that, even if there is a momentary delay.

If the moon blew up huge pieces of it would fly towards the earth causing a huge noise as they entered the atmosphere and hit the earth. Most of the life on the earth would probably be killed.
We would not hear the initial explosion since it is in a vacuum but we would soon hear and feel the effects.

Because the moon is in space, which has little gravity. Space is also like a vaccum, and sound cannot travel in a vaccum. If the moon blew up, we'd probably see something or be hit with parts of its rock, but we wouldn't be able to hear it because sound doesn't travel in space.

The moon is (as all the moons), daughter of the basic planet, assembled by low gravitation from the rests of explosions during childhood of mother-planet. Has no own rotation, and no internal life. If it started(for some strange reason)rotating,it should blow up immediately in the silense without any explosion or even noise.

Because space (which includes the area between the moon and the earth) is a vacuum, and no sounds can escape a vacuum.

There is no air between there and here,so sound cannot travel through space.

in order for their to be sound, something needs to be vibrating, when you hit the table, the wood is vibrating, when you speak the air is vibrating, in space however, there is nothing, it is a vacuum. this means that if something blows up in space, their is nothing to vibrate for us to hear on earth

sound needs to travel through a medium eg. air. since theres no air in space the sound cant reach us

Space is a vacuum in which sound does not exist
