Everyone else is wrong. (Ragebait.)
Speed of approach = speed of separation.
If the box left the blue portal at a slower speed than it entered the yellow one, the top of the box would be moving slower than the bottom of the box, which would compact the box dramatically during the transition, but we can see that its size is unchanged and it is still square.
The top of the box is pushed rapidly out of the blue portal by the bottom of the box being thrust into the yellow portal. (The bottom of the box is pulled rapidly up into the air by the top of the box which is already moving quickly.)
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
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?
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.
Stop stealing all my upvotes
There’d be no cube but yes
In the first moment of exit, it might look like this though
Speedy thing did not go in
Was going to post the correct Answers (A) but then looked at the post and though na. But if you want to know more about portals and how they would work in real life check this out. Great guy.
and his answer: https://optozorax.github.io/portal/?scene=speed_model
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.

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
The top of that masher is clearly protecting the cube from the rain, so I’m not sure how the rain is expected to shoot the cube out as in option B.
A.
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.
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.
It’s a superposition of both states until you make a measurement
More importantly, what if I straddle the blue one?
Img pls?
A, but it would have the average of the two states.
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.
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.
