If there was a huge explosion on the moon would we hear it?

Why would there be an explosion on the moon in the first place? And to answer your question...we would see it before we heard it.

Of course not.

No, but not because there's no sound. Sound waves travel through the interplanetary medium, which is not "space" but just an area even less dense than air. Even a brick of lead is mostly empty "space." The important thing is how often molecules bounce off each other.

Only at night.

If you are asleep, you would be able to tell there was a huge explosion by all the cheese on your front yard.

We would neither see it or hear it.

We would only know about it when cheese drippings hit our vehicles.

You would if your solar powered helicopter was flying close enough

not entirely, it it occurred on the other side of the moon, you know the other half that never faces the earth, then we most likely would not see it, unless there's cosmic dust and debris propelling outward from the site and even then we'd likely never see it from that side. We may never hear anything either unless there was stuff falling into our atmosphere. likely all sounds will be sucked in the vacuum of space and never reach us. So we may see it (assuming you're looking at the moon on a clear night and assuming it occurs on the side of the moon that faces us, and assuming it's a full moon to get the entire view and not a partial moon where the earth is casting a shadow on the part that the explosion occurs on), but will likely not hear a thing, unless the explosion actually blew up the moon. then probably.

No.

or would it be the case that no sound waves can travel through no air

Yes but only if you were looking at it from directly on the earths equator.

The moon is made of feces.

I weep for the level of ignorance in this country. There *are* two to four occasions annually during which Earth is "casting a shadow" on the Moon. Those are called lunar eclipses.

But the great majority of "partial moons" occur during the regular monthly lunar cycle, during which the Moon revolves around Earth and the Sun illuminates the side that faces away from Earth ("new moon"), then gradually and progressively illuminates the side that faces us ("full moon").

[And if an explosion "actually blew up the moon," we *still* wouldn't hear it on Earth, because there still wouldn't be a medium between the Moon and Earth that could conduct sound waves. If random chunks of the Moon entered Earth's atmosphere, *then* we'd be able to hear them as they broke/exploded apart, struck Earth's surface (most likely water), etc.]

All of this is stuff I learned well before high school...

Suppose the explosion resulted from the rupture of an enormous reservoir of compressed air, so large that it filled the void between the moon and earth and iwas pushed along by the explosion.

You beat me to it
