It never hurts to wonder. If we assume the Tic Tac is a man made craft, it doesn't seem a far stretch to also assume it may employ antigravitics. Perhaps it can be traced back to Die Glocke [1]. Your linked HN posts also mention Hutchison, an interesting character who appears repeatedly down the rabbit hole, where you'll also discover Schauberger and Leedskalnin. There's a lot of smoke and mirrors in these topics, which often delve into conspiracy and pseudoscience, making it hard to discuss them without sounding like a crazy person. In any case, it's fascinating to ponder, even if it's all just science fiction.
