[Death by Mirrors]

@mdom
The alien appears reasonably excited to finally have found intelligent life on earth. You only understand a small part of the following conversation - or rather monologue - about high tech equipment, quantum physics, and ribbon theory (which apparently takes string theory to a whole other level by tying those strings into a bowknot). Finally the alien waves goodbye and returns to the spaceship without harming you. Your head is still spinning from this encounter, but nevertheless you realize you're standing in a dead end. So you walk back to the last crossroads.

Go left, or go right?
