It's prolly lame but how a lot of things are relative has always been a wow thing to me. Like a sunset for me is simultaneously a sunrise for someone else. Well it's all things at once, it's always rising and always setting and always noon and always the middle of the night and all that, just depending on where you are. Just how things can change completely even though nothing other than yourself actually does.

Also all the timelines that become available or not just depending on the tiniest things. Like if you think of those stories bout people who first meet literally bumping into eachother in a store or something, eventually end up married and all that jazz. If one would've been just a tiny bit slower or a tiny bit faster at any point in their life then they never would've been in the right place and right time for that event to happen exactly the way it did and their lives would turn out completely different. That but with every single thing. It's really obvious but it still blows me away, and then on top of that just the huge number of things interacting and playing a part in it, which is i guess every thing in existence, just makes it even crazier to me
