Moving a portal effectively moves the entire universe. It doesn't feel like being accelerated because everything moves along. But it is what happens.
A more interesting problem is what if the piston suddenly stops lowering the portal over the cube when it's only part of the way through. The momentum of the top half of the cube would actually act against the gravity working on the bottom half and possibly lazily "suck" the cube through, depending on how fast the portal was moving. This is all assuming forces like gravity can't traverse the portal, since that would make everything even more of a bitch than it is already.
In the end, all this portal stuff is incredibly unintuitive & aggainst universe’s laws, but A’s premise of the the cube being inert on the other side shouldn’t pass under any circumstance. The cube is not moving before going through the portal but it has parts very much so moving while through the other side. The parts that have gone through are being acted on by momentum from the exit’s point of reference.
The cube is in motion after going through the portal and shouldn’t suddenly stop for no reason. So B is the correct answer at least if the speed that one portal goes at is high. The specifics of how the object will behave are wacked out depending on gravity’s relative angles (and strength!) from both reference points.
>>11598228>>11599036Are the retards that keep reposting the hulahoop analogy baiting? Or are there really such stupid people on this board? Do they not realise that with a hula hoop, both ends (the entry hole and exit hole) are connected and must move/translate together, but with two portals they're disconnected and can translate independent of eachother?
