Yea, it's quite obvious you don't.

No, it's not like a large cylinder retard. Because both parts of the cylinder would move at the same speed in your scenario. When in OP's scenario, one part (attached to orange) is moving and the other part (attached to the blue) is not. And you are cunningly trying to weasel out of this fact by calling it a "magic multidimensional wormhole" or some shit. Yeah, nice try.

Listen now. Portals act on their surfaces. Orange scans, blue prints. Since yellow is scanning faster than blue is printing there is accumulation of matter on blue portal's surface causing pressure. This pressure causes force that propels it forward. Therefore it's B.

Your cylinder logic is just shit.

B is the correct and pic related is why.
Portal act on their surfaces. Blue copies, yellow prints. Since blue is moving it copies faster than yellow prints so compression is created and that propels the box outward. Think what happens if the piston is moving near the speed of light - All atoms are copied and printed onto the yellow portal's surface near instantly and the box is compressed to a near 2D shape. The internal pressure will cause the box to bounce to an incredible speed.

>you can't compress atoms like this because atoms will push other atoms.
Bravo anon that's called a 'force' and it causes motion!

>but where does the kinetic energy of the box come from?
It comes from you pushing the piston retard. The piston isn't going to slide effortlessly, you have to apply pressure otherwise the piston will jam and stop copying the box (portals will refuse to copy). If you don't believe me consider if yellow portal was facing a metal wall. By this argument I can drop the piston onto the box effortlessly and the yellow portal will readily print the whole box inside the crammed space. This will of course create an immense pressure which will in turn create heat at the wall which I can use to boil water, turn the turbines and power a city. i.e perpetual motion.

But really it boggles my mind people would even think it's A only by considering newton's first law. You can clearly see the box moving while the blue portal is copying it and the yellow is printing it. The box should keep moving. What, do portals act as "pliers" until they completely copy an object?
