Insultingly Stupid Movie Phyiscs: Outerspace Explosions

“Star Trek originally got it right. In early episodes, when something exploded in outerspace, it made no sound. That’s because there is no air in outerspace to transmit sound…. Yes, an explosion probably would create an expanding cloud of gases which would eventually impact a spaceship in its path. However, in the vacuum of space this expanding cloud of gas would have a very low density. When it hit a ship some distance from the explosion it would probably sound like a gust of wind blowing against the spacecraft.” —Insultingly Stupid Movie Phyiscs: Outerspace Explosions (Intuitor)
