I sometimes wonder what I’d do if I ever got a time machine….
I guess I’d probably go back in time and stop myself from wasting time by wondering about something that’ll ‘never happen’, thus inadvertently preventing the existence of the time machine.
But then, if I prevented the existence of the time machine, how did future me come back in time to warn present me?
I guess the lesson here is that time is not linear, but a tangled web of intertwining events.
Oh, and you shouldn’t do acid.
