One afternoon in a bar in Berkeley I started talking to a homeless-looking guy about time travel. We talked for about an hour about the practicality of time, nature of reality, quarks, etc etc. I’m always up for slinging BS with the random crazy dude. After he left the bartender asked if I knew who the guy was. It turned out he was the preeminent quantum-mechanics physicist at UC Berkeley. Ha. I wish I’d taken notes. I had no idea.
I would love that.
