I mean even just walking up to something as simple as my house. I'm in awe of how any atoms are making up all the shit around me right now. Once you get to thinking on the level of the very tiny--it explodes your head when you pull back out and really think about it.
Here's a common mindfuck for me in that vein:
There's probably 10x as many atoms making up all the shit in my house as there are galaxies in the universe, carry that comparison out to stars/planets and the number gets a bit tinier.
Now zoom the fuck out to the macro scale----and then zip right past it onto the scale of the solar system, then the galaxy, then our galactic neighborhood, then the universe. When you go from tiny to big like that in your head you realize that the absolutely unfathomable numbers which describe the universe at its largest--are, in reality, described by numbers where are thousands of orders of magnitude larger than that if we discuss what stuff is really "made of" at its tiniest. For example, think of how many atoms across the universe is. Holy fucking shit balls I could hold my zero button for 10 days and not hit the right amount.
This can of pop I'm drinking has probably about 10^16th or 17th more atoms making it up (just the aluminum) than I will take breaths in my entire life.
Ugh. There's some shit that you immediately want to un-know once you know it--but you can't. Especially with it being so goddamn motherfucking interesting, and all (at least from my perspective).
