A passing line of dialogue in TENET led me to read up on
@ProfFeynman& #39;s theory that positrons are actually electrons moving backward in time and now my brain is buzzing. I feel like I understand both the universe (and TENET) a little more tonight.

The first turnstile sequence in TENET actually illustrates this concept dramatically: two individuals appear to emerge from the doors, but it& #39;s actually the same person entering and exiting at the moment their entropy is reversed. Our linear POV creates the illusion of two men.

Aaaaaand now I& #39;ve hit upon the part where there might only be one electron in the whole universe (which explains in the bizarre fact that _all_ electrons have _identical_ properties) and I& #39;m low-key freaking out. #SCIENCE
