If portals were wormholes then B could work, sadly they aren't so A is the closest thing to what you will get.
>>
It would be A and B at the same time depending on which perspective you're watching it from. It's A because from the cubes perspective it's staying completely stationary and the orange portal being slammed down on top of it is the equivalent of somebody dropping a hula-hoop over it. The cube wouldn't magically fly up into the air because you dropped something with a hole in it over it. But it's also B because if you were standing in front of the blue portal you would see a cube moving towards your face at high speed. Once the orange portal impacts the platform there's no reason the cube would suddenly lose all its inertia. It would fly out and hit you in the face. The people arguing over this shit are retards. It's an imaginary impossible scenario and therefor doesn't have a real world answer. It's like arguing about what would happen if 2 plus 2 equaled 5.
>>
>>585080003
You don't understand vectors? If the portal eats half the box in 0.01 seconds, then the tip of the box as it comes out the other end has traveled half width has traveled half it's width in 0.1 seconds, those particles will have very high velocity and momentum pointing directly out from the portal
You're thinking of portals as simply acting like a window, which is how they act when they're stationary, but the math changes when the portals are moving

Why? What changes?
>>585080890
Argument a: from an outside observer, your speed remains the same. An observer looking through the portals would see an instantaneous speed change.
Argument b: from an observer looking looking through the portal, your speed remains the same. An outside observer will see an instantaneous speed change when a portal is moving.

So in that video, B happens because chell maintains the same speed when observed by someone looking through the portal. But someone observing outside would see her instantly gain the Velocity that the moon was moving at (2000mph)

the fact that there is a force acting upon the object that's going through the portal?

In OP's image there is the electrostatic force acting on the box, constantly accelerating it upward.
>>
The problem is that Afags are actually stupid. Like, not as an insult, but as an objective fact, they just haven't learned physics. Either they have little intuitive understanding of it, or they never took some classes on it, or some combination of these. There is nothing wrong with initially thinking A, but when you ignore the entry portal, and solely imagine observing the cube through the exit portal, you can see how that contradicts A and it falls apart. They refuse to acknowledge these contradictions, and just resort to dumb shit like the portal is moving the cube or whatever.
>>
>>585081603
There's a force that makes chell keep up with the moon's orbit instead of following earth's like she was on the other side of the portal?

Correct. If it has speed it keeps the same speed. If it has no speed going in then it still has no speed going out.

Bfags continue their lost cause. Refuse to listen to the in game explanations, either deflecting or insulting over their constant loss.

Without preasure or friction on the cube itself it goes nowhere. No momentum is being imparted to the cube this it does not go anywhere. An object at rest tends to stay at rest. Basic physics yet b will never undstand due to their willful ignorance and baseless vitrol.

The cube isnt moving so it would be A. if the cube was being tossed into the portal it would be B
>>
As demonstrated time and time again, such as here: >>585082398, Afags literally don't understand the argument that Bfags are making. Bfags completely understand what Afags are saying, like "it's a doorway" or "the cube isn't moving", and clearly lay out how their arguments are wrong.

Afags remain willfully ignorant, and never actually address the arguments that Bfags make.
>>
>>585082806
...which is?
>>
>>585081507
Problem with that picture is it's using a reference point when portals like this means there's two valid reference points that contradict each other. Your graphic is true and is what people standing in front of the blue portal would see. But what if you were standing right next to the force meter 3000 looking into the orange portal? You would see pole not moving at all while the cube gets closer to it until it touches it. Once the cube touches it, it still has some forward momentum and still want to travel towards you but since it's being blocked by the pole it would stay stationary on the tip of the pole. Once the portal stopped moving the move wouldn't start moving in the opposite direction because from the poles perspective all that happened was somebody pushed a cube up against it and then it stopped moving. This is why debating this shit is meaningless. Portals contradict the laws of physics by having two different valid reference points for motion that contradict each other.
>>
>>585082398
Then how does it exit the portal in A? What forces act upon it?

Now is when you go portals aren't supposed to make sense like the bAit-fag you are.

>>585082889
it doesn't 'exit'
the portal isn't a wall that you pop out the other side when you jump through it. it's a window. The yellow portal comes in contact with the floor of the pedestal. The surface area of the blue portal effectively becomes the floor of the pedestal. The cube then falls from gravity
>>
>>585080003
the momentum is transferred from the moving portal to the cube, it just tugs things

I'd say it "appears" on the other side at the rate that the portal is moving. the cube never moves.

we can calculate this simply as the extremely light atmosphere of the moon is well-known.
>>
>>585083197
The rod just breaks.
>>
>>585083236
So if you freeze frame when the portal is halfway over it and then go frame by frame forward is the cube not changing position?
>>
>>585082875
>"it's a doorway"
It's not a doorway, because both the exit and entrance to the door are moving together. In the original picture, imagine the platform was falling down without a piston, and the blue portal was on the opposite side of the orange portal. It would just pass over it normally.
>"it's not moving"
It is moving out of the exit portal. If the orange portal is moving down slowly, the cube will exit slowly, if it is moving quickly, the cube will exit quickly. In order to emerge out of the blue portal, the cube must be moving some distance. Since cube is moving some distance over some period of time, which is literally how velocity is defined.
>>
>>585082967
For A, it accelerates downwards eventually reaching a very high terminal velocity since there's a lot less resistance on it with no ends. For B and C, it would probably destroy the rod when you move the portal.
>>
>>585083325
if you froze time you would just see half of the cube will be on one side of the portal, and the other half will be on the other side of the portal. did you play the games?
>>
>>585080329
The ending proves A you moron. If B was true then the relative difference in movement direction and speed between two celestial bodies would rip anything going through the portal to shreds.

yes, well, luckily your frame of reference literally does not matter at all. The only frames of reference that matter are the two portals.

yeah that's the thing. potential energy is entirely dependent on the viewer. Much like velocity, it doesn't really "exist". You measuring potential energy only gives you information. It does not describe some innate property of the cube.

It's not the same thing at all wtf. The momentum of the platform going upwards gets transfered to the box when it comes to an abrupt end, which is what sends the box sailing. There's no momentum acting on the box from a portal falling down.

Both of these cases change the scenario to make it look like you're not a retard. You're substituting the continual displacement of matter as the portal moves down the length of the pole for any actual force that the portal imparts on the cube or pole in question. Where does the sudden accelration come from if B is true? What force does the portal transmit upon objects that pass through it?

Relativity, dumb faggot. Here let me answer your question with a question: Is the portal exiting the blue portal as it enters the orange one? If you made a video of the scenario would you be able to see the cube coming out of the orange portal inch by inch as the blue portal is dropped over it?

The answer is yes, which means there is motion. Whether you can understand that or not is irrelevant.
>>

holy shit you understand nothing.
the whole point of the image is position and therefore velocity can not be determined without a point of reference. all the tools you mentioned create a point of reference.

>>585080003
Our model of physics doesn't allow for objects to move relative to themselves so the question doesn't actually make any sense to begin with and thus cannot actually be answered.

There's always going to be an unresolvable conundrum left with whatever answer you go through.

>B
Where does the momentum come from?
>A
Where does the velocity go?
>>
>>585080003
as it exits the portal, it is in motion relative to the space around it, therefore it has momentum and remains in motion
>>
>>585087441
OK, and how does a hole (which is what a portal is, by the way. A hole in space) moving impart a force on the objects that move through said hole?
>>
>>585087316
but velocity is always relative. the whole point of the image. velocity is not an innate property, but a descriptor assigned by an observer.
>>
>>585087854
>Where does the velocity go?
Gets smashed against the stationary platform. Do that Japanese "sou desu ne" shit they do where they smack a closed fist onto an open palm, where the fuck did your velocity go?
>>
>>585087926
Because it continuously connects different points in space with another fixed point. Two atoms can't occupy the same space, pushing each other away.
>>
>>585087339
Kinetic energy is a relative quantity. The amount an object has depends on whose frame of reference we're looking at it in - you can't just hit "pause" on the universe and measure some absolute, objective amount of kinetic energy it has.

Kinetic energy is only conserved within a particular frame of reference. The portal allows an object to move discontinuously in a third party's frame of reference, which means that, from their perspective, kinetic energy is not conserved. The object moves through the portal interface continuously, and so it does conserve kinetic energy relative to that - it exits the interface with the same momentum relative to it that it entered with. The portal is not "conferring" energy, it's shifting the box into a frame of reference in which it *already* had that energy.
>>
>>585087926
it's not imparting any force. the cube begins moving as soon as the portal begins moving, because the portal is moving space around the cube
>>
>>585087854
>where does the momentum come from
It is easily demonstrateable in-game that portals pull momentum out of their ass. Because momentum is a vector, whenever you leave a portal in a different direction than you entered, momentum has been transformed. Whereas speed (NOT velocity) is absolutely preserved.
>>
>>585087615
The portal exerts neither a magnetic force nor a gravitational force on anything as far as we know. So explain the mechanics responsible for the transfer of energy.
>>
>>585080003
It has to be B. The cube needs to exit the blue portal as fast as it enters the orange portal or it will collide into itself.

I feel so bad for B fags who dont understand how wormholes work.
>>
>>585088078
Speed is preserved between portals that have the same speed, just as momentum is conserved between portals that have the same direction.
>>
>>585088119
The cube must necessarily exit the portal at the same rate of speed that it enters the portal.
If the moving portal is going at 1m/s the cube must exit at that rate of speed. If the moving portal is going at 100m/s the cube must exit at that rate of speed too.
>>
>>585088153
thats not how it works, the force is being pushed down on the solid blocks until it fully envelopes the object. why are a fags so deceptive

>>585088280
That's why I said portals of different direction. If one portal is at a 90 degree angle to the other, your velocity (and therefor momentum, but NOT speed) has been completely transformed.
>>
>>585088339
>the force is being pushed down on the solid blocks until it fully envelopes the object
Why though? Hell, how does it know it's fully enveloped the object, or partially enveloped it?
>>
>>585082398
>An object at rest tends to stay at rest
how does the cube exit the portal if it has no movement in relation to the exit portal?
>>
>>585088339
But what if it isn't being pushed down on the solid block until it fully envelopes?
Does the block just fly upwards anyway?
>>
Afags, try a thought experiment with me, tell me if I’m wrong. You’re watching the blue portal side with a view through the portal at the box. The plate comes down at, say 100MPH to theoretically launch the box. Imagine the first moments of the box passing through the blue portal. From its passing the threshold to lying parallel against the angled surface, it’s traveling on blue side upwards towards the launching angle at one hundred miles an hour. That’s not debatable, that’s just how it works. So then, after those initial moments, if A were true, where the hell does that launching momentum go? Portals can’t add momentum but they can’t remove it either, and the box is, relative to blue portal, still approaching at launching speed.
>>
>>585088339
How does the block know if it is being fully or partially enveloped and why would it react differently depending on which
>>
>>585088153
The part that goes through the portal pulls the rest of the cube through, causing the entire object to inherit the momentum from the portal.
>>
>>585088539
What force is acting on it to make it fly upwards? It has touched nothing and thus cannot have gained any energy.
>>
>>585088492
Me watching the gif in >>585082398 from a birds eye view isn't going to make the man launch up into the sky.

for the millionth time, the cube has no momentum, only the moving platform does. Portals are not teleportation devices, they're wormholes that physically connect 2 different spaces of 3 dimensional spacetime, the same way that drawing a two dots on a piece of paper and then folding the paper so that they're next to one another doesnt mean that traveling from one dot to the other across the plane of the paper is any different than moving to the left or right of the dot on the unfolded paper. theres no special momentum required to move the cube to the space on the other side of the blue portal any more than is required to move the platform without any portals being there.

Imagine holding your hand outstretched and moving it slightly to the right. Moving your hand through a portal is no different than doing that and having your hand be in the living room next door because those two points of space are physically connected the same way space next to your hand normally is.

The only momentum acting here is the momentum of the platform the orange portal is on moving downwards, which is absorbed by its physical contact with the other platform.
>>
>>585083340
It's not moving out of the exit portal, at least not in terms of physics affecting it as we'd expect. You have to consider what forces are affecting the cube as the portal passes over it. Wind? Very little, if any. Gravity? Until it hits the halfway point, it's a constant downward pull (and at the halfway point it sort of becomes diagonal due to how the exit portal is oriented, until fully passing through). There's no force acting upon the cube at any point other than gravity. It may not make -sense- that it wouldn't fly out because it suddenly appears on the other side, but there's no logical explanation for it to somehow get the momentum generated by the platform coming down on it--unless some spooky portal force exists to justify it
>>
>>585088662
>it has touched nothing
Wrong.
The cube has been touching the platform it is sitting on the entire time, before the portal even started moving.
>>
>>585088767
>>585088306
>>
>>585089007
But velocity (and therefor momentum) is relative. Put the viewpoint on the platform bearing the orange portal and now the cube has momentum.
>>
>>585089007
>Portals are not teleportation devices, they're wormholes that physically connect 2 different spaces of 3 dimensional spacetime
They're literally not wormholes. It's canon that portals use quantum tunneling.
>>
>>585080329
The entry portal is stationary relative to each observer, so this doesn't prove anything
Chell is thrown into space by the air currents, not the portal or the surface it's on.>>585089007
>for the millionth time, the cube has no momentum, only the moving platform does
In general relativity, there is no difference between the cube moving or the platform moving. So long as two things are heading toward each other, they both feel like the other one is the one moving and they are the stationary one

>>585088726
>>585088756
Watching that gif from a top view isn’t comparable because in that scene the “blue portal” house in this instance is still the factor that’s retreating from your stationary position. You also didn’t answer my question. If the box is already moving upwards at the launching angle at 100 miles an hour indisputably until the very moment the box would either do A or B, where does the velocity go for A to be true?
>>
>>585088930
Yes, but at what point does the cube have a force acting upon it other than gravity pulling down?
>>585088306
But where does this sudden burst of speed come from? The cube never has a force acting upon it other than gravity, always pulling down. You say it 'must', but the only physics-fuckery going on is the portal allowing instant traversal from one location to another
>>
>>585089159
Welcome to relativity kiddo. There is no such thing as absolute momentum or velocity.

That's impossible. She enters through both portals, once at the beginning and once at the end.

>>
>>585089230
>The cube never has a force acting upon it other than gravity
The portal guns use miniature black holes to generate the energy to create the portals. Since the portals have been created using a gravitational force how can you say there is no force acting on it?

Nah. Me watching a bullet going into ballistics gel at a high speed camera doesn't mean the bullet travelled at a slow pace. Likewise me observing a box coming to it at a rapid pace doesn't mean that the platform that the box is on is the thing that's moving.

It's neither, portal 2 doesn't make sense since if two ends of a wormhole have different momentums relative to each other, the g forces at the event horizon would mathematically sum up to infinity, destroying anything attempting to travel through it.

The direction changes the moment you pass through the portal (or more accurately, it changes on the parts of you that pass the event horizon). There still has to be momentum of -some- form to enable movement, and in the cube there is none

The whole B ethos is that input speed equals output speed. Anything else (direction, relative velocities between the portals) is nullified by the portal's properties. Chell gets succed in at 10 mph on earth so she leaves on the moon at 10 mph, nothing more nothing less.

>>585089976
Momentum is preserved, but not direction as the other guy said above. The portals effectively treat anything passing through it like it's passing through a window. Even though it might be moving one direction going in, the moment it passes through it's moving in the same direction it would be moving if it had passed through just the exit portal

Please at least read the wikipedia article on concepts you clearly don't understand. Direction is part of momentum. A change of direction is a change of momentum.
>>
>>585090105
But as it's been said 1000 times ITT, speed is relative. It doesn't matter if the portal is heading towards the cube or the cube is heading towards the portal. From a physics standpoint they are absolutely identical.

Its not like you go faster through a portal than your normal walking speed, its never implied that anything other than normal gravity or force affects you while going through a portal. you could put something half in/half out of a portal and it wouldn't get pushed out either way by the portals energy or whatever.

This makes me think that both A and B are impossible. It is impossible for an object with mass to travel at the speed of light, however if you imagine a similar scenario where the spaceship is travelling half the speed of light, and the rock is thrown slightly faster than the speed of light, intuitively it would seem that the rock exits the portal at a speed faster than light. This, of course, is impossible. Therefore, I think that it is impossible for two portals to travel at different velocities relative to each other. Afags are retarded and conveniently ignore any attempt to refute their arguments, so I'm just gonna say if you're an Afag and disagree with what I just typed you can choke on my semen.

Judging by the amount of absolute A-tards in this thread who are so smugly assured that 2+2=5 based on pure social inertia and hubris, humanity doesn't have much of a chance. The people are so borderline retarded, I honestly wouldn't be surprised if they were skubfags too.

Good point. What would actually prevent you from doing that irl?

>It's a videogame moon.
It's a skybox with a moon painted on it. Nothing's ever moving in video games anyway, it's just light emitted from the same location all the time.

How can anyone use pics/vids/ingame physics as proof, when the maker of those things decided how things gonna work(so they actually made the results)?
Game physics have nothing to do with real life even if they use equations from actual physics.

This question cannot be answered since portals break physics completely, you cannot showcase anything because thats gonna be your interpretation how things would work.(some anons elaborated on this, how objects cannot move towards themselves, multiple ref points, etc)

Lets say you have 2 planets in an otherwise empty universe and one of them is moving and the other is stationary compared to a random reference point in space. You can be on any of these planets only, and you have to decide which one is moving. If you stand on any of them, the other planet will seem to move. you have speed/movement relative to other things. This frame breaks with portals

Nothing, an outside observer would however not measure you going faster than light. See https://en.wikipedia.org/wiki/Velocity-addition_formula

>frostbite on the other
You wouldn't freeze that quickly as your body can only lose heat in space via radiation

>Therefore, I think that it is impossible for two portals to travel at different velocities relative to each other.
Literally happens in Portal 2 in the level where you use moving portals to cut the pipes on the neurotoxin machine.

Watch some videos on relativity/inertial reference frames. Unironically, it's interesting stuff. Many use that exact scenario to explain stuff.

HAHAHAHAHAHAHAHAHAHABAHA

Nothing asymmetric.

What's that got to do with anything?

Did you think the arguments in these threads have been about real portals all along? Holy shit.

But the issue is that "exiting" the portal at speed x literally means that the atoms of the cube are going to appear in the new location at that rate, once nothing can appear anymore because the portal stopped moving the cube will just be affected by gravity because it was at rest
>>
>>585095436
There is no such thing as absolute momentum. From the perspective of the exit portal, the cube was moving at the speed of the entrance portal.

Kinetic energy and potential energy always interact with each other and their sum is always the same. If an object is free falling all its potential energy is transformed into kinetic
>>
>>585095776
>their sum is always the same
Not with portals involved.
>>
>>585093191
>This makes me think that both A and B are impossible
It's not impossible, it's that our current understanding of physics can't properly explain it
>>
>>585095436
But the cube is not going to be one singular godlike entity, it's comprised of trillions of separate atoms. Imagine the scenario in OP's image, and think about the moment when 1/10 of the cube is through the portal. Those atoms that are already through the portal are on the other side, there isn't anything more the portal is imposing on those atoms. So in between that point in time and a moment later with 1/2 of the cube is through, the atoms that were already through the portal have change position, despite not going through the portal. Specifically they were displaced the distance of the new 4/10ths of the cube that went through the portal in that time. How do they move from these two points without having a velocity and without going through the portal?
