Not really, no. And it isn't a stupid question at all. When you go somewhere where there isn't air, there are a lot of things that behave rather differently (heating and cooling for instance, but that's a different story altogether).

It isn't so much the air as some "medium" which transmits sound. Go stand next to a really loud speaker at a concert sometime and you can feel the floor vibrating. That is a sound wave travelling through the floor. This is also why astronauts will touch their helmets together if they want to talk directly to each-other: the helmet glass transmits the sound between them.

In space, there is no medium to transmit the sound. So your exploding ship wouldn't be heard by anyone. The gas that escapes would spread out far to quickly to actually allow you to hear anything. So all those wonderfully loud explosions in Star Trek, Babylon 5 and all the movies in space wouldn't actually sound like anything at all.

I couldn't actually find an article about this on the main BA website. HEY PHIL! Think you've got time in that schedule to do a short thing about sounds in space? You could even touch on the Galileo/EOS plasma noises, pulsar blips and various spacecraft vibrations (those aren't all sounds, but can be readily converted into sound, and some are quite strange when you do that).

[note: dang... looks like I wasn't fast enough on this one... oh-well. the more explanations, the better, right?]
