Question

In a movie, while showing the explosion of a spacecraft in space, a flash of light is shown along with sound at the same time. What are the errors in this depiction?

Answer 1

Space is a near-vacuum, so there is no medium for sound to travel through; the explosion sound would not reach the listener. Light can travel through vacuum, so the flash would be seen. Also, sound travels much slower than light, so even if a medium existed, the sound would arrive later than the flash.
