Hmm, similar to how heavier than air flight was thought to be impossible for humans? Interesting how the will of a few can shape humanity. I love it.

- threevox 5y agoProbably a pretty good analogy! Even now, it's not known whether time has directionality in any way that is meaningful in physics. FTL travel would resolve the "Arrow of Time" question (https://en.wikipedia.org/wiki/Arrow_of_time https://en.wikipedia.org/wiki/Arrow_of_time) but this wouldn't invalidate much/any of physics because the arrow is essentially non-observable at the micro level
