*Yes, the physicality of time is something I've noticed as well.
   *It's also not a "straight line" either or a block but connects
   in a myriad of ways, all hidden in the ways we talk about time,
   I believe. "gap" or "bump" is about the best way I can think of
   it. *Like if you're a 1D line, the 2nd dimension would intersect
   and appear strange... a gap, a bump, something... "not quite
   regular". *Even if it's just pencil marks on a page drawn in a
   direction you can't perceive because you're 1D you might ask,
   "Why is this different?"
