Was anyone else ever concerned that you might get cut on the edge of portals? I mean, hypothetically, then portal edges would be like, 1 molecule thin. So you could easily get something clipped off if you hit one at a bad angle...
There would be a wall on either side.
It's like if there was a door, but the door frame, and the walls around it were all one molecule thin, so all the edges of the door frame would be really sharp
