Over my head too, haha. Relying on stuff I've learned almost ten years ago and have looked more into more so out of curiosity without any sort of rigor, so I'm just trying to figure out what the initial post was supposed to mean (I got that moments make up time, and that seems like something many would get right, so I guess if it's "some science many get wrong" I'm not understanding how Pennynail is explaining it).
