- TimSchumann 5y agoThanks for the writeup! Glad to see you around.
- audiometry 5y agoWouldn't pressure waves travelling in opposite directions interfere with each other?
- potatochup 5y agoOnly if you're exactly on the opposite side of the world I think?
- tehbeard 5y agoIf you were exactly opposite the source in terms of distance traveled by the waves, yes?
- yetihehe 5y agoIf they were opposite waves (One negative wave, one positive wave, emitted from two points opposite on the globe) then yes. But if they are both positive, they just add in place where they meet and then travel away as they did before.
- acidburnNSA 5y agoCorrect, and I saw somewhere on twitter that someone near the antipode did see a huge pressure wave from constructive interference.
- DrBazza 5y agoLooks like a 2mb initial fluctuation - any idea what Krakatoa was, that circled the world (at least) 7 times?
