Answer 2

Answer

These sounds are only in his head and are not carried through space, since space has no medium through which sound could transmit.

Explanation

Sound travels by causing materials to vibrate and in the process of that vibration carry sound waves along. Unlike electromagnetic waves, sound waves do not travel in a vacuum.  The information of the destruction can not be carried through space as there is no medium whose vibrations can carry it. The correct answer is medium.
