A science fiction film shows an explosion in space that is claimed to be heard by the travelers on board a spaceship. EXPLAIN why the travelers COULD NOT POSSIBLY hear the explosion space. Use your knowledge of waves to provide EVIDENCE for your argument.
sound waves are caused by compression and rarefaction of the air.
No air in space.
Possibly, if you were close enough, the gases produced by the explosion would be thick enough for sound to propagate for some distance, but in that case, the sound would be the least of your worries.
