Question

Obi Wan hears the destruction of a planet and all of its people through 'the force'. These sounds are only in his head and are not carried through space, since space has no _____ through which sound could transmit.


electromagnetic wave

electrons

magnetic field

medium

Answer 1

The correct answer is **medium**. Sound requires a medium (such as air, water, or solid materials) to transmit through, and since space is mostly a vacuum with no medium, sound cannot travel through it.
