Aliens with Control over Gravitons in the KHz Range

Click For Summary

Discussion Overview

The discussion explores the hypothetical scenario of aliens capable of emitting or interacting with gravitons in the frequency range of human hearing (20Hz-20KHz). Participants speculate on the potential applications and effects of such abilities, particularly in relation to gravitational forces and sound perception.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant suggests that if aliens could emit gravitons in the audible frequency range, they could potentially use this ability for communication, although it would be inaudible to others.
  • Another participant proposes that fluctuating gravitational forces with AC signals could cause mass to vibrate, leading to destructive effects by hitting resonant modes of objects.
  • There is a repeated mention of the wavelength associated with a frequency of 300 Hz, indicating a significant scale for the effects of such gravitons.
  • Some participants discuss the implications of gravity acting similarly to acceleration, suggesting that individuals within the gravitational field might experience effects akin to being on a giant speaker.
  • Concerns are raised about the perception of sound, with one participant questioning whether direct signals would be heard and discussing the potential for Doppler shifts and interference in large structures like amphitheaters.

Areas of Agreement / Disagreement

Participants express various speculative ideas about the implications of aliens controlling gravitons, but there is no consensus on the feasibility or specific outcomes of such abilities. Multiple competing views and uncertainties remain regarding the effects and perceptions of sound in this context.

Contextual Notes

Limitations include assumptions about the nature of gravitons, the scale of effects, and the conditions under which sound perception might occur. The discussion does not resolve the mathematical or physical implications of these ideas.

See my previous post! https://www.physicsforums.com/threads/do-gravitons-have-frequency-like-photons.957146/

Let's say we had some aliens that had the ability to emit/interact with gravitons with frequency roughly in the range corresponding to human hearing (20Hz-20KHz), and that they had an energy source that could generate them with sufficient magnitude. What could they do with that ability?

300 Hz it around 1,000,000 meters wavelength.

I suppose you could sing anthems with that skill. No one else would hear it but they would.
 
I assume gravitons are meant to transmit the "gravitational force", so if you can fluctuate the gravitational force with AC signals, wouldn't mass then vibrate along with it?

With enough power this could be extremely destructive, going around hitting resonant modes of things.

Strong enough, and we should be able to hear.
 
Since gravity has the same effect as acceleration, it'll ~ feel and do like everybody in the beam sitting on the membrane of a giant speaker

I believe the eardrum is co-moving. You would not hear the direct signal. You can hear a Doppler shift in a passing car. There is no change in someone's voice when you talk to them inside the car.

I am not sure if you could get interference in echos. If you were in an amphitheater the sound quality might change. The amphitheater may need to be 1000 kilometers scale building.
