Wouldn't the signal travel time of energy pollution be the speed of light? Certainly faster than the speed of sound, but still geological timescales.

- ben_w 6y agoSure, but if all you want is an existence proof, it’s still possibly better because it removes the requirement that whoever made the noise needs to still be there (FSVO “still” given how simultaneity behaves in relatively). OTOH, also worse because it’s unlikely to be directional, so the output would have to be powerful even compared to the galaxy it’s part of for an intergalactic detection.
