Verb Adjective Adverb Expression

In science-fiction films, huge explosions in space are usually accompanied by a deafening roar. In reality, though, this could never happen, because space is completely silent. Sound simply cannot travel through the emptiness between the stars.

The reason lies in how sound works. Sound moves as a vibration that passes from one particle to another, which is why it needs a medium such as air or water. Since space is a near-vacuum with almost no particles, there is nothing for the vibrations to move through. So if a star exploded far away, no matter how violent the blast, it would reach us in perfect silence.
