Can music really be transmitted faster than light?

Click For Summary

Discussion Overview

The discussion centers around the claim that music has been transmitted faster than light, exploring the implications of such a phenomenon and the underlying physics. Participants examine the nature of music transmission, the speed of sound versus light, and the potential for optical or electromagnetic transmission methods.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants assert that music travels at the speed of sound, arguing against the possibility of faster-than-light transmission based on this fact.
  • Others propose that if music were transmitted, it would not be in sound form but possibly as an optical signal, referencing past claims related to quantum tunneling.
  • A participant mentions the concept of group velocity exceeding the speed of light, suggesting that this does not violate relativity.
  • There are references to tachyons and Cherenkov radiation, with some participants discussing the theoretical implications of superluminal particles.
  • One participant recalls a specific experiment involving the transmission of a radio signal through a medium, which was claimed to have traveled faster than light, but acknowledges that this remains disputed.
  • Another participant emphasizes the need for clarity and sourcing in discussions about such claims, highlighting the importance of accurate information in physics discussions.
  • Some participants express skepticism about the validity of the claims, suggesting they may be based on misunderstandings or technicalities.

Areas of Agreement / Disagreement

Participants generally disagree on the validity of the claim that music can be transmitted faster than light. Multiple competing views remain regarding the nature of the transmission and the implications of such a phenomenon.

Contextual Notes

There are unresolved assumptions regarding the definitions of music transmission and the conditions under which faster-than-light claims might be considered. The discussion also touches on the complexities of wave propagation in different media and the implications of relativity.

I've seen a few, but remember that I'm new here. Anyhow, I got to get to work now. Catch you later.

My $.02. The experiment is not very convicing. It may look good on the surface, but not when you dig deeper.

The situation is somewhat like this. Suppose I claim that I have a psychic that can receive "information" faster than light. And I have an experimental result that supports this. The experiment runs as follows:

We have a mechanism that generates the following numbers - it's not random, it's a pre-recorded message. It goes something like this:

1,2,3,4,5,6,7,8,9,10,11,12

We send the first 12 numbers in the sequence, and we ask the psychic to predict the next number in the sequence before it arrives. The psychic, based on the information that was received, correctly predicts that the next number in the sequence is 13.

Have we convicingly experimentally demonstrated the transmission of "information" faster than light by psychic means? I would say that we have not.

How does this analogy relate to the experiment? - Mozart is music, which is a strictly band-limited signal. The propagation delays being measured are on the orders of fractions of nanoseconds (less, actually). On this scale, Mozart looks essentially flat, because the highest frequency in music is 20 khz. 20 khz * 1 ns is 20 / 1,000,000 of a cycle. Over an interval of such a short duration, sines and cosines look essentially flat.

To be convicing, a much wider bandwidth signal would need to be sent, or a much larger timespan than a few nanoseconds would need to be used if one insists on using Mozart.
