I also once thought of that, but maybe there are other ways in which large vibrations have left fingerprints on materials. I don't mean gravitational waves, but really acoustic phenomena. Like a comet impact or a vulcano outburst. What's a delicate material which would be able to record sound but that doesn't get destroyed by time? Clay that dries up is a logical one.
- eganist 8y agoOld glass or porcelain might be the most viable candidates for a first look as they would be cooling off from a heated, more malleable state, potentially capturing sound from the immediate vicinity as they cooled off. I have no science to back this up. It's just a hunch.
- ianai 8y agoThat may be complicated from old glass never fully hardening. But it sounds plausible enough. Possibly mortar in walls could record the workers taking. All sorts of pottery start out malleable, so they might be candidates. Cave paintings might be an option - wonder whether being finger painted would leave biological fingerprints behind - heart rate, for instance. Pretty wild idea. Here’s hoping it has some legs. Maybe someday we’ll learn about places like Stonehenge this way.
- ghusbands 8y agoOld glass doesn't flow and is solid. Google it to see plenty of debunking.
- lostmsu 8y agoInterestingly, gravitational waves might end up a good idea. We now have a couple of patterns to look for, and many giant concrete slabs might have them accidentally recorded.
