Wow, that's certainly enough trippy for the day. This fun Twitter thread from @Foone shines light on some bizarre things that our eyes are (or aren't) doing. It is troubling to think about a hostile alien race showing up one day that exploits our eyes' saccades, and manages to wipe us out because we can never see them, and all along our eyes have just been taking their best guess at what's around us. Maybe they're already here. Maybe that's why we can't see them. What an eye-opening thread.
