      The atoms in the air you’re breathing are billions of years old, and the molecules could have been made 5 minutes or a billion years ago. Probably both in the same breath.

          Well, it’s kinda cool to look around and also realize that much of what you see likely came from multiple supernovae and/or kilonovae. (Huh. I have never needed to pluralize the word ‘kilonova’ before. Meh… It looks cool with the ‘e’, so I’ll leave it.)

          Eventually, our atoms are going to get blasted out across the universe again to maybe become part of some other planetary system, before it eventually gets destroyed or sucked into blackhole and is evaporated as radiation. This might not even be the first universe our bits have been a part of …
