While watching a recent science fiction movie, one klingon spaceship blows up a droid spaceship with a laser gun. the klingon crew watches out the port window and covers their ears to muffle the noise from the explosion. scientifically, this scene is inaccurate because
a)
light can not reflect off objects in the vacuum of space.
b)
they would not be able to see anything outside the window.
c)
lasers can not be transmitted through the vacuum of space.
d)
the sound of the explosion would not be transmitted back to their ship.

D)  the sound of the explosion would not be transmitted back to their ship.

Explanation:

Sound is a mechanical wave. A mechanical wave requires a medium to travel and transfer energy. It travels be compression and rarefaction of the medium. Since in space it is vacuum, the sound energy by the explosion of the spaceship would not be able to travel through the space, the Klingon crew are not required to cover their ears to muffle the noise. This scene would be inaccurate scientifically.
