Let’s say an object were to pass through the edge of the portal, with half of it going through the portal and the other half just passing it. Would it be cut in half?
I mean if someone goes through a portal but only got half of their body through it before it closes; then yeah, they'll probably be cut in half or something like that.
There was this one episode in Fringe where a guy was going to another universe through a portal but someone else closed it and he was like half cut off.
