Help: Sound created over/in subspace? (SciFi)

Click For Summary
SUMMARY

The discussion centers on the concept of sound transmission in subspace, a fictional construct in science fiction narratives. Participants clarify that sound cannot travel through the vacuum of space due to the absence of a medium, and subspace, as depicted in various sci-fi works, does not exist in reality. The consensus is that while radar and other technologies can detect electromagnetic waves, they cannot transmit audible sound across empty space. The conversation emphasizes the distinction between scientific principles and fictional elements in storytelling.

PREREQUISITES
  • Understanding of basic physics principles, particularly wave propagation.
  • Familiarity with the concept of sound as a mechanical wave requiring a medium.
  • Knowledge of electromagnetic waves and their detection methods.
  • Awareness of science fiction tropes, particularly regarding faster-than-light (FTL) travel and communication.
NEXT STEPS
  • Research the principles of wave propagation in different media.
  • Explore the physics of sound and its limitations in a vacuum.
  • Study radar technology and its applications in detecting non-audible frequencies.
  • Investigate the role of fictional constructs like subspace in science fiction literature and media.
USEFUL FOR

Science fiction enthusiasts, physics students, and anyone interested in the intersection of scientific principles and fictional storytelling.

Help: Sound created over/in subspace? (SciFi)

I know nothing, called basic high school physics and chemistry. However, do not hold back in your answers I do find ways to comprehend what people tell me.

This might be a silly question but since audible "sounds" can't travel over empty 3dimensional space and there is no such thing as sub-space would it be possible to "hear" frequencies and disturbances somehow use a "radar" other than radio telescopes over extreme distances?

I know I am only thinking in waves and not other energy forms but this is the basics of my (lack of) knowledge. This is SciFi but I am pretty serious as to where this answer takes me. Science Fiction always amazes me because it's only fiction for a small amount of time. Compared to civilization and even the universes timeline.

Thanks and I hope I am not wasting your relative time!

There is no such thing as Sub-Space. It is pure fiction, invented to allow FTL travel and communication and etc. Nor do we know of any other dimensions other than the standard 3 for space and 1 for time.
 


Thanks!
