There is no evidence remaining that the sound exists. It would be like trying to detect an energy below the noise floor of vacuum energy; there is no proof that you can construct that it exists. Once it's part of the background noise floor, it effectively seizes to exist.
- TekMol 8y agoWell, you just repeated the argument that when we cannot measure it anymore it does not exist anymore. But my question is: Is that true? Why? We also cannot measure stuff outside of the observable universe. Yet we do not say nothing exists beyond the observable universe.
- zaarn 8y agoBecause there is no reasonable way to possibly prove the sound still exists. To find out if something beyond the observable universe exists, you simply wait for the light to reach you. Every minute your observable universe grows larger and you see more stuff, the obvious conclusion is that there is more stuff. But the random movements of air molecules allow for no analysis that there is a quantum of a sound traveling through it. It cannot be reasonably proven that the sound still exists. You can't wait to see if you notice more random sounds or anything, it's gone, part of the background noise. The information in the sound has been destroyed for any way to measure it via the movements of air molecules.
- TekMol 8y agoYou cannot wait for light from beyond the observable universe. That is the definition of the observable universe. The universe is expanding. The further away something is from us, the faster it is moving away from us. The part outside of the observable universe is so far away, that it is moving away from us at a speed faster then light. So we will never know anything about it.
