This video. Wow.

I mean, unless you’re a judge or a theologian, who really cares whether or not there is free will.  But the idea that every moment in time exists simultaneously,  how cool is that?  I’ve never been a fan of the time travel trope, because if the Earth is turning while orbiting around the Sun, which is orbiting around the supermassive black hole at the center of the Milky Way galaxy, which is undoubtedly doing a bit of moving around the universe as well, surely that must totally complicate popping back to “yesterday” or 1812 or whatever.  You can’t just aim for a past time, but you must also aim for a past place and you’d better be insanely good at calculating it in several different polar coordinate systems simultaneously.  I don’t know about you, but my math isn’t anywhere near being able to even ask a computer to do that for me, although I suppose there would eventually be an app  for that.

But where was I?  Oh, yes, I’ve never been a fan of the time travel trope, but if relativity is right (it’s explained very nicely in the video; you really should watch it), and all time exists simultaneously, wouldn’t it be great if you could learn how to look through it and see any time or place you wanted to, or make some connection?

You could go to a seer, but instead of having them merely look into your future, they could help you look into your past.  Then you could visit it, sort of, as if it were a place you could travel to when you were homesick for old clothing styles or people you hadn’t seen for a while because they died or just changed too much as they got older.
