The common belief is that there is no sound in space, but this isn’t entirely accurate. While space is largely a vacuum, which prevents sound as we know it from traveling, it’s not devoid of all sound-related phenomena.
In space, instead of sound waves, there are electromagnetic vibrations. These vibrations can’t be heard by human ears in their original form. However, they can be transformed into audible sound waves through special instruments.
For example, spacecraft can carry equipment that converts the radio waves emitted by planets and other celestial objects into sounds we can hear. This process allows us to “listen” to these celestial signals.
NASA has developed sophisticated instruments capable of capturing these electromagnetic vibrations and converting them into sounds audible to humans. The sounds you might hear from such recordings are the actual sounds of space, unaltered and unique.
They’re often described as both beautiful and haunting, evoking a sense of awe similar to the reactions one might have to the music of renowned composer Hans Zimmer. This shows that while traditional sound does not exist in space, we can still experience the energy present there through advanced technology.
So, while the common saying that “in space, no one can hear you scream” is essentially true in the context of sound waves traveling through a medium, space is not completely silent in the broader sense of wave phenomena.
