What do you think?

But in this case the portal has no mass, therefore no momentum is transferred. And the edges of the flat surface that the portal aren't even touching the box so their not even part of the system(if you were considering that)
Try hitting a ball with a tennis racket, but cut a big hole in the racket, and don't let the ball touch the edges. Tell me if the ball flies in the same direction as the racket when you tried to hit the ball

if it's A, And the Cube is not moving, then it would exit the 2nd Portal as a 2 dimensional square. all instances of 3rd dimension would exit the blue portal and just stay right there.
Andrew Roberts
your tennis racket argument proves B, thank you
Christopher Flores
This case is A. If the platform the box is on was the one moving, it would be B.
Take a piece of cardboard and cut a hole in the middle of it. Place a tennis ball on the ground. Drop the cardboard over the ball so the hole falls over the ball. When the cardboard drops past the ball, the ball doesn't magically shoot up. That is what is happening here.

A what is the problem here? cube got no motion here

Blue portal isn't moving though
Adapting your example, bottom of the cardboard is moving, but top is stationary
Colton Torres
B, and I encourage people saying A to put their face right in front of the blue portal during the test. I'm sure the box closing rapidly on you will lose all momentum just because.
