There’d be no cube but yes
In the first moment of exit, it might look like this though
You can’t place a portal on a moving surface in either game, so neither.
So the cube is just smashed?
It’s a practical answer which is slightly upsetting because I wanted more discourse.
what about the portal on the moon?
This was answered decades ago
In that situation both portals (the inside and the outside window frame) have equal, but opposite velocities and therefore cancel out any momentum from the person.
When dealing with OP’s scenario, only one portal is moving.
The object going into the portal has no momentum so it would be A.
No momentum in relation to what? Momentum doesn’t exist in isolation.
To the space outside of the blue portal. Moving the orange portal doesn’t drag the whole surroundings, so assuming both places are on the same planet, the momentum of the box in relations to both places is the same
As Optozorax taught us, gravity must act through the portal.
Well, it doesn’t in the only source of knowledge we have: the game Portal. I don’t know enough about gravitational forces to have a coherent theory on it, gravitational waves moving through space-time is a bit beyound my real understanding. But in the game if you put a portal on a ceiling, it doesn’t “suck” you until you’re throuth it, so there it isolates gravity somehow.
At this point, I consider Optozorax’ research the primary source of how portals work. If the games disagree, they’re wrong.
If you stick to the premise that the portals exist in a universe with GR, then we can pay much know that space-time is locally flat in and around at least the middle parts of the portal. We know this because things don’t get fucked up when they’re going through.
Moving the orange portal kinda does ‘drag the whole surroundings’. It moves an entire universe.
The cube is stationary relative to the universe of the platform it’s on, but it has momentum relative to the universe through the portal. The question is which universe is the cube in? What is the boundary of the portal surface?

I’m giving so many people Fs on this assignment because you failed to read all the instructions.
The correct answer is B due to the graphical conservation of speed lines.
I did it deliberately.
Lemmy reads more than most but people aren’t good at reading
I choose A because that would mean I could use the portal to fuck myself in the ass easier.
Trying to conceptualize what that would be like is making my head hurt.
Momentum is conserved when passing through a portal. In the reference frame of the out portal, the object has no momentum, so it plops out.
Speedy thing did not go in
If we’re only supposed to do ragebait answers, then anyone who passed 3rd grade science would be able to tell you the answer is obviously B
If you actually played the game, and paid attention in physics class in highschool, then you would know the answer is clearly A, and everyone who says it is B really needed the simplified explanation from GLaDOS to understand how to play the game.

Not providing a link to alternative platforms is my ragebait

Neither, I’ve already gleefully incinerated that fucking cube before it got to this point.
It’s a superposition of both states until you make a measurement
A, momentum is in the portal, not the cube
Neither. The cube is not making contact with the portal at all, since the portal is on a stationary block with some speedy lines drawn on it. Speedy lines don’t nake thingy go fast - everyone witb a gel-hairstyle knows that.
