A.

Definitely A. why the fuck would it be B? If you threw an open doorframe at an object, would that object suddenly start accelerating?

this is also stupid. it doesnt matter which one is moving. it would just plop out both ways

Someone emailed valve and the dude that was behind the physics said A is the correct answer.

relative to the door, yes

Actually both A and B are plausible depending on speed cube enters portal (or weight of cube too). If slow enough its A if fast enough B.

In your doorframe analogy its not A either. Because object is not leaving doorframe. It would be like platform suddenly stopped without entire cube crossing it

>Implying the cube can move relative to itself

There is no correct answer, portals don't exist

It's been done and it just doesn't work because the portals weren't designed to move.

what about that one scene in portal 2 with the nerve gas tube and the laser?

But they are always moving

But portals in the real world are spherical.

Portals disappear when a platform moves

WHY WOULD THE CUBE GAIN MOMENTUM?
If a wall fell on you, but you stood where the open window was you wouldn't shoot foward. Portals are jusr two connecting points like both sides of a window.

>A faggots still think moving portals don't cause weird shit

Because as the cube goes through the portal, every part leaving it is stationary, cause it to be pushed by the next part leaving it.

The cube pushes itself, it's that simple.

This.

Wrong. The bottom one moving means the two machines collide which causes the cube to go flying through.

you're not just wrong, you're stupid.

The steel beam is destroyed how is that relevant ?

The force doesn't have the strength to break that either.

drop a piano on your head retard

prince of space here. A is the answer

see

Theory of Relativity, bitch
B

Both A and B are correct. It is the movement of the cube that matters, not the movement of the portal.

Mage of Rage here, you’re full of shit and momentum does not work that way.
If it did cars wouldn’t work

Valve half-assed the implementation of moving portals for that puzzle to work. Anyone who thinks you can use the game itself to prove this is a dumbass.

See

because from the perspective of the wall, you ARE shooting up into its window. didn't you study forces in high scool? saying that a car rolls at a certain speed is the same as saying that the road just scrolls under its wheels at that same speed. it all depends on your point of reference.

If this doesn't convince you to be B, then I don't know what will

The portal "surface" stretches over the cube and the cube doesn't pass through.

Let's LARP as even bigger retards than we actually are: the thread

Force of platform do not matter, speed matter, fast enough ti would break steel beam, slow enough beam would be bend by gravity outside of blue

I'm seeing some compelling evidence for B, but there's one thing I still don't get: Why isn't the trapdoor analogy applicable?

My understanding of the source engine physics makes me say A. Hypothetically, B could work, but it's still breaking the laws of physics by existing.

>speed
The beam isn't moving

Consider the system in the middle of the cube's transit through the portal

The Cube is halfway through

If I observe the blue portal I see the cube moving out

The object is in motion

Objects in motion remain in motion unless acted upon by an outside force or object

The cube will remain in motion

B

/thread

What if the beam is too strong to bend?

The beam is strong, the wall is strong, the speed at which the orange portal moves does not create a strong enough force for the beam to break the wall. Logically there must be something that stops the portals as a form of resistance. I am saddened the image apparently needs explaining, I figured it was obvious what it was conveying.

Easy the motor moving the beam explodes.

Because portals aren't trapdoors, or hula hoops, or doorframes. The concept of a doorway where the entrance is mobile but the exit is not is a physical impossibility that would cause weird ass shit to happen.

This entire problem is a case of people going for the option that looks like it makes the most sense because they haven't thought about the implications of what's actually happening. It's basically the portal equivalent of the Monty Hall Problem. Thing is MHP can be proven so only the most stubborn imageboard user would try to argue otherwise. Since portals do not exist we do not have that benefit.

Portals are suppose to be non issues, you enter with the same velocity you exit.

I don't get the MHP either

Which is actually precisely why some force would be created. Because by leaving a stationary doorway while also being stationary yourself, normally a physical impossibility, you would logically be getting pushed by every part of your that's also leaving it.
As long as you don't actually try to argue that a proven mathematical concept is actually wrong you're good.

how can someone go so far to shitpost, it amazes me
