>>5516 A because the cube is not in motion.

I vaguely remember a physicist talking about this. This is solved because the game says portals do not affect momentum. Velocity is relative. Whether the object is moving or stationary to our frame of reference is irrelevant. Physically, there is no difference between an object moving into a portal at 10m/s or the portal enveloping the object at 10m/s. Relatively speaking, they're the same. Physics is not intuitive.

*shits on your thread*

C: the cube comes out crushed

D: I give the portal the D.

Neither, no right answer because portals are a paradox.

>>5517 But motion is relative, and the universe beyond the portal is in motion towards the cube.

>>5704 You could fuck yourself in the ass using portals between walls that squeeze your front and back so your dick starts in your ass. You couldn't thrust but you could wiggle.
