Questions and Answers

What is the primary reason for the misconception that there is no sound in space?

Sound waves in space are quickly absorbed by black holes.

Most of space consists of a vacuum, which does not allow sound waves to propagate. (correct)

The sound waves are too low in frequency for human ears to detect.

Galaxies and galaxy clusters do not produce any sound waves.

How were the sound waves from the Perseus galaxy cluster made audible in this new sonification?

The sound waves were converted into light waves and then back into sound waves in a different frequency range.

The sound waves were combined with other sound waves from different galaxy clusters to create a harmonious melody.

The sound waves were amplified using advanced audio technology.

The sound waves were translated into a higher frequency range by scaling them upward by several octaves. (correct)

What characteristic of galaxy clusters allows for the propagation of sound waves?

The strong gravitational forces acting within the clusters.

The presence of black holes at their centers.

The copious amounts of gas that envelop the galaxies within the clusters. (correct)

The high density of stars within the clusters.
