Fine, let’s say it’s held on with elf cum. I’d love to see you explain how that matters.
The box moves in relation to the portal opening. The reference frame is the portal opening. If, from start to finish, the box takes 1 second to enter the portal, it has to take one second to exit the portal.
Whoop, you made an incorrect assumption there. You are only using a frame of reference that includes the box and the portal, any conservation of momentum is only valid for that frame of reference.
