In sci-fi movies, space battles often depict massive explosions accompanied by loud booming sounds in outer space. Why is this representation scientifically incorrect?
Space is too cold for sound energy to exist
Outer space is a vacuum, so sound waves cannot travel
Sound waves move too fast in space for human ears to detect
Gravitational force in space pulls sound waves downward
Solution
Outer space is largely a vacuum containing virtually no air particles, making the propagation of sound impossible.
