You can't just decide that one portal is more important than the other. The blue portal is still standing still. Also, I can't imagine a doorway that you can pass if both it and you are standing still.

they are two sides to the same portal not 2 portals. Fundamentally they work like a door or window, you go in one side and come out the other, but a portal can separate the two ends, and moving one of the ends is moving the entire portal.

>>377313560
which one is that?
stationary thing go in, speedy thing come out is the frame of reference argument.
frame of reference imparting energy implies that everything that has gone through the portal has memory of it's previous """universal""" position and is thus affected by any movement their entry portal makes. going through the entry portal again would double this effect.
>>
>>377313904
>they are two sides to the same portal not 2 portals.
One side of which is moving and one of which isn't.

I am actually imagining it like a door or window, and any way I envision it, it ends up looking like B.
>>
>>377313963
I'm still not sure which one you're trying to argue against. A is the one that requires the cube to have a memory of its "universal" position but B is the one that works with frames of reference. The whole concept of several frames of reference seems to me mutually exclusive with a universal frame of reference.

You can not argue for A without assuming the existence of a universal frame of reference. If you want to argue for that, you'll have to prove Einstein wrong first. B is the only plausible answer, and even that's debatable since portals don't really adhere to physics.

Realistically, the only answer that matters is this one >>377313678

>>
>>377314229
Go stand next to it. You'll see it stays right where it is.

Look, this is pointless. You can't just arbitrarily decide that one side of the portal takes on the qualities of the other one and not the other way around. The reality is that portals create two frames of reference that are both true at the same time. The portal is moving AND not moving. It is moving relative to the Earth, to the cube, to itself, even. However, it is also standing still relative to all those things.

You look up and see a window on the ceiling, through this window you can see a room. Suddenly the ceiling begins collapsing towards you, the room through the window is getting closer. The windo eventually falls around you. Do you think you are going to go flying into the room? or is the room going to "crash" around you?

You look down, there is a window at your feet, through this window you see a room. Suddenly the floor of this room is getting closer, like its ceiling is collapsing. You are going down towards the floor so nothing will fly up out of the window.

this is the key, the orange portal is falling around the cube, its like this scene from buster keaton https://youtu.be/FN2SKWSOdGM?t=37 except on the other side of the house facade is a different system entirely because portals entrance and exits dont have to be adjacent.

Okay, imagine a cube next to a portal. You're looking at the cube through the portal. The portal on your end beings to move. Now you will also see the cube move, but it is also standing still.

Now, imagine the cube is halfway through the portal. The portal is moving. You will see the cube move. Half of it is standing still. Half of it is moving on your end, though it appears to stand still on the other end.

Finally, imagine the cube is entirely through and keeping pace with the moving portal. It is moving in its entirety, but on the other end of the portal, someone would see it remaining still.

When you're dealing with portals, moving and standing still are relative concepts.
>>
>>377314701
Right, then you simply misunderstand because you were actually arguing against A.
>>
>>377314385
How the hell does it favor B? They don't go anywhere when the portal hits them, which is what happens in A.

>>
>>377314673
You really don't need so many words to say "it's like a hula hoop" three times when you should already know I fundamentally disagree with that concept.

The crucial thing here is indeed that on the other side is an entirely different system where everything is different, including the speed of the cube.

Portals do actually transfer energy, though. Stick something halfway through a portal. Move the portal. Does the object move with it? Congratulations, the portal has transferred energy.

If the object doesn't move then it snaps in half which also requires energy.

Im saying it 3 times because clearly you dont know what it means, if you did you would not disagree. All a portal does is bend space so that 2 surfaces behave like the same surface. It does not break conservation of momentum laws. You learn how to work with multiple systems and reference changes in first year physics courses.
>>
>>377316495
B actually works if you consider both points of reference. A tries to argue there's one, objective point of reference.

If we ignore gravity and wind resistance and have the cube floating in space as the portal engulfs it and moves on, you would see that the cube subjectively maintains its position as long as the portal keeps moving.

Completely backwards. A requires the cube to remember that it's supposed to be standing still after it conveniently forgot long enough to exit the portal. B only argues that the cube maintains its speed relative to the portal, which it already had from the portal's point of view.

I disagree precisely because I understand the full implications.

The bottom example of your pic. It shows one "reality" being dropped on the other. However, this is functionally identical to the bottom reality being shoved into the one on top. The real point is that the cube moves from the bottom reality to the top one, and therefore has to obey the rules of the top one. There, the portal is stationary and the cube is moving. Doesn't matter what it was before because the cube has left that reality behind.

Thinking about this, I would imagine the cube would start moving even before it was completely through the moving portal. There would be an emergent "force" experienced due to the reference frame shifting.
>>
>>377315671
From the moving portal's frame of reference, the cube moves through it at whatever speed the portal is moving. Once the moving portal becomes motionless, so does the cube, from its perspective.
>>
>>377318842
youre not making any sense.
the cube never moves because the cube never moves except in magical B rules where you magically make the cube move because FRAME OF REFERENCE MAKES THING FAST like how youre going the speed of light right now relative to the light emanating from your computer screen.

the absolute reference frame in this case is the platform the cube is standing on.

Basically, what this guy says. >>377318105
>>
>>377318546
Yes it does, because it means that a moving portal functions more or less like the door to a vehicle, just a vehicle with its own internal laws of physics. Nothing on the outside affects it, but nothing inside it affects the outside. If you want to know what happens to something that comes out of the portal, look at what's happening from the perspective of the portal it comes out of, not whatever the "actual" situation is according to its internal rules of physics.

This is all a simplification of course because there is no "internal" and "external" and in reality it's all the same space but it functions identically.

You don't understand physics enough to argue this. An absolute frame of reference is a reference frame that would appear at rest to every observer in the universe. The only way that the cube could be seen as motionless form the portal's point of view is if you assumed this absolute reference frame existed, and that the cube was motionless on it.
>>
>>377318282
Depending on the speed it wil continue its movement upwards.
>>
>>377318994
That's what I thought for a long time as well, but I've since come around to the perspective that as the cube exchanges one frame of reference for the other, its previous stationariness takes on the aspect of movement and it will behave as if it was already in motion. It will only experience acceleration if the portal speeds up before the cube is entirely true.

The portal doesn't apply any force or pressure to the cube.
Thus with no momentum all it does is slide off the slope due to gravity.

Portals do not add or remove any acceleration.

Two interesting (and relevant) features were found about CMBR (The cosmic microwave background):
it comes from every direction (consequently it is universal, i.e. can be seen from anywhere), and it is very consistent in intensity from every direction (termed isotropic). This means that anyone, anywhere, can measure their speed relative to the local knowledge of the universe. Furthermore, this effective reference frame can be used to measure velocity irrespective of the expansion of the universe, if one considers certain interpretations about comoving reference frames. Although this is very different to a universal reference frame of an aether, it is certainly, in one sense, a universal reference frame. Tick one to Lorentz

The cube is stationary and not being pressed towards anything. It's relative floor just changes orientation due to the slant of the slope.

There is no pressure caused by the moving portal because the other side is stationary.

>>377320217
As I said. Relative to the portal. Which it necessarily must have or it would not be able to pass the portal.

Now, because the portal is stationary, and because there must be relative movement between portal and cube, the only way the cube is going to pass through is if it is moving.

Which is really no surprise because any thought experiment that involves chucking something through a moving portal shows that the portal's movement does in fact transfer to the object in question.

>>377320509
The floor of the cube becomes solid pressed against the slope. That's how it's pushed out.

But it does not add pressure because there is no acceleration or force added to the cube. It's literally just a hole. Make an O with your fingers and drop a object through. If it's not touching it will just fall straight down. The hole doesn't add anything

Actually, if the orange portal were to continue moving downwards and the cube was able to ignore gravity and wind resistance, then, looking into the orange portal, for the cube to remain "still" it would have to be shooting out the other side.

OK so lets simplify it, remove the angle factor.

The rules in both systems are the same.
Now replace the portal with just a hole.

If we use the reference point of the hole, the ball has velocity, but does not go flying when the platform stops, the same applies with the portals, because they are holes. The ball will be affected by the new gravity and behave accordingly but will not gain momentum.

Using the blue portal room as the system you have to treat the orange portal room as one solid object as it is not moving in the universal reference.
>>
>>377321021
If it's straight like that then the cube wouldn't go anywhere as the portals would sit on top of each other and the cube is still on the ground. Right?
>>
>>377320512
>As I said. Relative to the portal. Which it necessarily must have or it would not be able to pass the portal
Yes but b implies that the cube ends up flying away and no matter how much energy the portal could tranfer its imposdible for the cube to to do that

>there is literally no force acting on the cube
>but it somehow receives the energy of the falling portal
>>
>>377321296
you can clearly see the cube having an upwards movement outside of the top portal, and we havent established that the cube is somehow glued to the ground.

Air pressure isn't added or taken away since portals dont add anything.

>>377312813
neither is possible because moving portals that do not move relative to each other cause a paradox of movement that at the very least current physics can't comprehend at the worst is completely impossible to exist.

A is right because what we percieve as momentum is actually the cube to expanding outwards
>>
Momentum relative to the blue portal doesn't mean anything because it's a separate system from the orange portal. If you actually played the game you'd know portal speed has no affect on anything, it's chell's input velocity relative to the surroundings that determines her output properties.

>>377322506
It doesnt disappate any air. It's not adding or taking anything away. It's literally like a open window.

The air pressure is equal on both sides even if one portal is moving.

so would you say that a stationary window has just as much air passing through it as a moving one? because that's what you're arguing

>>377324223
Yes. The area surrounding the window would have pressure, but the hole itself would also have none.

The pressure isn't added into the hole because it is a fucking hole.

what you fags are failing to understand is conservation of momentum

the box isnt moving, and the crusher plate doesnt add any moment to it since there is no resistance going through a portal

the box would never do anything more than slide down the ramp after the crusher descends on it, even if you COULD put portals on moving surfaces

>>377329190
The system is both portals though since they are connected, the platform the cube rests on, the piston, the slanted surface with the portal, its all one connected object. Only the cube is separate, theres no way for it to fly through the air as it never moves, nothing is ever acting on it other than the change in gravitational direction.

It is the second room that is moving, because it is the piston that is moving.

>>377330471
Al movement is relative, it doesn't matter if the cube moves or the room moves. It doesn't matter if the portal is slammed on the cube or the cube is slammed on the portal.

I go hard on this. The cube is experiencing G-forces relative to the speed of the portal as it goes through.

What happens here is actually correct. The air around the portal moves freely, not with the solid surface. Think if a car zoomed by, there would only be a slight force of air.

No force is exerted on the cube whatsoever in the original "plop vs launch" argument. The blue portal is simply placed over the cube, enveloping it just enough enough to pop out the other side. The speed is irrelevant since the a pillar never touches the cube. If the cube and blue portal switched spots so that the full force of the pillar would physically propel the cube through the portal, the answer is B. But since that isn't the case, it's A.

How the cube enters the portal is irrelevant, how the cube gets from one portal to another is irrelevant.

The only thing that matters is that the cube imparts energy on itself, that part of the cube coming through the exit portal has to push the part of the cube already though out of the way.

This would result in the cube moving away from the exit portal at the same speed as it went into the entry portal, regardless of whether the cube or the portal was moving.

I have posted this before, wish I had saved it for easy posting, but;

I posit that if moving portals created momentum, then it becomes impossible to move portals through space occupied by matter.

As soon as a layer of cube reaches the exit node of the portal, it has momentum and speed. It should attempt to pull the rest of the cube out. Simultaneously, the rest of the cube has resting inertia, and which would resist the pull. Should the momentum of the exit node portion of the cube exceed this resistance, it will begin pulling the rest of the cube through the portal, increasing its speed, but if that were to happen, then the moving entrance node would push the cube down as it moves down. Thus the only option being a net remaining in place at the original location.

Then realize that what is creating this impossible distortion of momentum is the portal itself, and that the cube must be resisting passing through the portal entirely.

Q.E.D.

Also, to address the "Ship enters stationary entrance portal with a backwards moving exit node":

Ship (with some momentum) begins to enter portal. Portion of ship on exit node of portal is suddenly slower than the rest of the ship. This loss of speed ripples towards the side on the entrance node, reducing the speed of entry, which in turn reduces the speed of exit in a negative feed back loop that only ends when the ship isn't moving fast enough to enter the portal (i.e. complete standstill, or, if the entrance is moving instead of the exit, moving at the exact speed of the entrance)
>>
>>377340683
I could simply swap B for A and almost all of these points still apply. The most important one is:

>another Afag completely self defining the mechanics of a portal so that his mental gymnastics make sense

My argument is based around things that are outside of the portal where portal physics don't apply. Afags make assumptions and define special mechanics to prevent basic physics from taking place in the space away from the portal with no way to back anything up. Sometimes the best answer when you don't know how things work is the most obvious. An object in motion will stay in motion.
>>
>>377349813

Anyone who has played the game knows that momentum that an object already had is maintained between the two nodes of a portal. What is portrayed in the video is normally impossible in the game.

Not him but both break laws of physics, and we are left with "which breaks the least" but I see where A comes from, as they, like you said, try to explain it without giving the portal any special functions beyond the obvious connection of 2 surfaces. This is the easiest to understand explanation of the A side in this thread.

>>377352229
>try to explain it without giving the portal any special functions beyond the obvious connection of 2 surfaces.

Like you say, a portal only connects two surface. It does not do anything to the space outside of the portal. Therefor any object that is not in the portal will obey classical mechanics. A cube is a continuum and not a point mass. You can look at only the leading section of the cube, block out the rest and pretend there isn't even a portal in the problem as far as that section is concerned. I do not need to explain how it started moving to be able to say that it will continue to move since it is out of the portal and basic physics apply.

I will agree with you that the cube may simply not be able to go through the portal and would end up infinitely thin when it tries to come out into itself. However, my argument for B is based on the problem description, which shows the cube on the other side. To argue otherwise, you will need give the portal special functions such as warping the space and time outside of the portal.

The exit is the only thing that matters with these kinds of portals. You can say they aren't a wormhole all you want but they function exactly like a wormhole does.

Despite what the game says, how something enters a portal has absolutely no effect on that object or the portal, as you can see through demonstration in the game. All physics that could be applied to a hole in a wall are applied here in every single way.

If you shoot a ball into a hole on a moving platform, will the object change directions once it moves through that hole unimpeded? No.
From the objects point of view when going through a portal it is maintaining the same exact direction, momentum, and speed. Portals do not have any effect on the object which enters them whatsoever except changing where they exit when they enter.

Portals break the link between conservation of momentum and conservation of energy. CoE is broken by portals which is why they can never exist.
>>
>>377354276
I think it would be 2 since the parts of the ball on either side would affect the exit angle in different ways which would unlikely result in a straight exit but it all depends on the numbers and values. The certain thing that would happen is that even if the ball wasn't spinning before would start spinning as it enters.
