The guy who made this pic managed to completely miss the point of the paradox.

What do you believe changes between the scenarios?

The cube is moving, both portals are stationary. In the original picture the cube is still and the orange portal moves onto it.

"Stationary" doesn't exist in physics.

It will leave the exit portal at 1m/s (and then fall back in and plop on the ground)

psychics aren't real...

Portals are not real so any proposed solution to this problem is inherently nonsensical. Please stop.

what's a cube

Real physicists will give you the same answer. Theres simply nothing in physics to allow for the cube to lose all of its momentum after becoming fully engulfed by the orange portal. It must keep moving relative to the frame of reference, ie, the blue portal, until other forces can counteract that momentum.
Its easier for brainlets to imagine riding on top of the cube, looking up at the orange portal. The world on the blue side is rushing towards you. You enter the orange portal, the world keeps rush forward, even after you're fully through you'll keep moving forward. Why would you stop dead as soon as the cube has been fully engulfed? You still had all the speed and momentum even after you were fully through the portal but the cube wasnt yet. That energy needs to go somewhere, so you either get flattened as the portal absorbes all that energy, which clearly doesnt happen to objects moving through a portal, or you keep moving forward, ie, shoot out of the portal.

Nothing in the rules of geometrical transformation. It is a fine teleportation in both cases.
The orange to blue portal transformation is (aside from redefining the orientation) exactly opposed to the velocity of the orange portal relative to the cube. In short the initial velocity of the cube relative to the END portal that defines (to a rotation) the velocity out relative to the end portal.
For instance, if the blue portal also move with the same velocity as the orange one, you are in the window configuration, so the cube moves away from the blue portal at the initial velocity. That is, it is static in the laboratory frame, as expected from the simple window experiment.

B fags cannot refute this. Taking the cube-orange portal relative velocity and neglecting the orange-to-blue transformation (or equivalently, cube to blue) is misleading and cannot even account for the simple window configuration.

Bfags are so annoying, dont think of a portal like two different things, think of it like a hula hoop, when a thing goes in one side it goes out instantly on the other side. Pass a stationary thing through a hula hoop and it stays stationary going out, now add some energy to something by throwing it through the hula hoop and it goes out with the same energy. Now i know that both the entrance end exit of the hula hoop are stationary relative to each other but in a wormhole scenario the speed of an object on which a portal is placed does not affect the wormhole, so they're still just an entrance and exit with no energy of their own. The speed of the surface on which a portal is placed only affects how fast does the object appear on the other side, it does not add any energy to the object because it never has any contact with the object. Only an object that has energy entering through the portal, by the law of conversation of energy, keeps that energy on the other side, speedy thing comes in, speedy thing comes out.

If someone drops a hula hoop over you and it hits the ground below you, you don't suddenly get thrown into the air at the same speed the hula hoop hit the ground around you

This is impossible.

Oh my god, the orange portal and the cube are both traveling to the left with the cube going just a hair faster. The theory being from A that the cube would exit from the blue portal at the difference in speed between it and the orange portal but then go its actual speed relative to the blue portal which is not moving.

It's getting confusing because I replied to someone mixing the lettering and offering another scenario.
The cube slowly plopping out in the original meme picture is the correct choice, and the rapid projection fags are wrong.

no see a real Afag would say that it's exiting the portal at 0m/s somehow

And you exit the hula hoop at the speed it was going around you, then IT gets stopped by the ground.

Physics have been geometricized since Galileo and that has only gone further and further in that direction.

Exactly, you exit a hula hoop at the same speed you entered it, only the exit is placed somewhere else. Glad we agree.

This would be exatly the same in A, but go ahead with the strawmans, it only proves you can't actually refute it.

But you didn't enter it. It went around you.

If someone drops a huge cardboard box over you, you didn't jump into it. It moved over you.

Read

>You can't put portals on moving objects in the games
The moon doesn't move relative to the observer?

the rebuttal is and always will be the same, it's just been repeated so many times that people don't even bother with it
a hula hoop's entrance and exit move at the same velocity
the portal's entrance and exit in this scenario move at different velocities
therefore the box itself must change velocity to make up the difference

I never understood how there could be so much debate on the subject of all the portal hypotheticals. It's the same as an object passing through a hula hoop. The only difference is one side is somewhere else. The speed of the hoop has no bearing on the speed of an object moving through it. The only nuance is in stuff like OP where both are moving, but then it's just an abstract physics question. Also, the OP's gif is disingenuous as without knowing what speed the cube is traveling, you can't determine how much of an effect gravity would have on the cube once the pull of gravity changes.

Can someone post the A vs B original image again? I keep forgetting which one is which

>This would be exatly the same in A
What? It'd phase into your head?

Threadly reminder that this shit has nothing to do with physics and everything to do with personal psychology.
There is no "correct" answer because the universes in each portal fall it of phase as soon as one portal moves relative to the other.

gravity literally doesn't fucking matter, why do afags keep bringing it up

the game's engine is actually rendering this as a stationary portal and a moving map

what mod? looks rad

you can't put portals on moving surfaces

The cube emerges from the blue portal at a relative velocity 1 m/s upwards. The force of gravity would cause it to decelerate until it goes back through the portal. Since the cube emerged at 1 m/s upwards it would probably leave at about 1 m/s downwards, having accelerated 2 m/s in the opposite direction. This would result in the cube having slowed down to 998 m/s on the other side, 2 m/s slower. This means the cube is now slower than the platform with the orange portal which will then gain some distance, specifically 1 meter every second.

Not really. I've created a map myself where I put portals on 2 surfaces that simultaneously move in different directions. All it takes is a single console command:
sv_allow_mobile_portals 1

You do know what we're talking about right? The whole premise of the discussion is that the portal's entrance and exit are moving relative to each other.

>if I cheat, it works like this!
Great, and I made a mod that proves the opposite, what now?

Yeah, us smart Bfags think the box changes velocity to make up the difference, while those crazy Afags think the box...changes velocity...to make up the difference...

Just make a Hammer map

Portals aren't teleporters that transport an object across something
They're holes in the universe that are connected
The speed of one portal's edge does not matter when the other portal's edge is stationary

Not functionally though.
At least you agree you're making up new rules to explain your opinion.

So do you agree that is it the velocity relative to the exit portal that is relevant?

The hoop is one possible portal configuration, and failing to account for it disqualifies an explanation.

Portal entrances are functionally a doorway opened between two points. It doesn't matter if the doorway moves, because the portals never move relative to eachother, hence the whole "hula hoop" comparison that Bfags have so much fucking trouble understanding. It doesn't cause something passing through the doorway to suddenly gain momentum.
See pic related. The only thing that changes for the cube is which direction gravity is pulling.

Have you never actually played the second game? In the neurotoxin generator sequence, there are 2 sets of pipes that you have to cut with lasers. That means you have to put moving portals on 2 different sets of platforms. They move in different directions. You can place portals on both of them simultaneously. The game itself proves it's possible.

>The hoop is one possible portal configuration
if the the entrance and exit were moving at the same velocity, for example if you dropped a sheet of metal yourself that had a portal on either side, then yeah, it would act like a hula hoop
but the in scenario in question, the entrance and exit are moving at different velocities, meaning it's not acting like a hula hoop

Portals as a concept violate the definition of velocity your fucking mongoloid
These threads are stupid because portals inherently break physics as a concept, A vs B is literally just a question of HOW it breaks physics

>It doesn't matter if the doorway moves, because the portals never move relative to eachother, hence the whole "hula hoop" comparison
the whole hula hoop thing is the most retarded argument in existance. Even if the cube isn't moving, with only the entry portal moving into it, the exit portal doesn't retract to reveal the cube. The cube MOVES out of the exit portal. Therefore in the moments when it's moving out of the exit it has a certain speed. A fags think that speed suddenly disappears the moment the cube is wholly out.

>You can't put portals on moving objects in the games, based brainlet.
you can in multiple occasions

Wouldn't the table it's sitting on exert a normal force

>literally every puzzle in the games

isn't this the B scenario in the original pic though?

Oh. Don't remember that part. Nice SFX.

portals can't exist on moving objects though. you never do that in any of the games

People give solution based on how they interpret portals to work in general. Some of those tentative explanations fail in the particular configuration of the hoop, so they are discarded. This is the case of the relative-velocity to-entry-portal explanation. It is perfectly fine to invoke this scenario against this interpretation.

moved the goal post, now both cube and door are moving. original question just had 1 moving

Did you even play the games?

The cube does not move. It has no kinetic energy. The only forces applied to the cube are gravity, friction, and air resistance.

velocity is change in displacement over change in time
the cube is displaced out of the portal the same rate as the moving platform is displacing it
the change in time is the same
thus, the cube has the velocity of the moving portal, thus B is the only rational outcome
A violates this

>Some of those tentative explanations fail in the particular configuration of the hoop, so they are discarded
like what?

No, they don't. You can see in that .gif that both portals are, for all intents and purposes, always "moving" at the same velocity. This is because a portal is functionally a doorway linking two points in space. You can't move two halves of the same doorway away from eachother and have it be the same doorway, and this is what Bfags don't understand. Portalsare ALWAYS moving equal to eachother.
The cube isn't moving. The space around it is moving.

this gif proves OP is right though, what are you on about?

The developer said that were it up to him, he'd make B the correct option, because it's the option that makes the most sense from both frames of reference (both the blue and the orange portal).

In the case of A, the cube behaves differently between the portals (moves fast relative to orange, stands still relative to blue), so energy is lost somewhere between the portals.
In the case of B, the cube behaves identically between the portals (moves fast relative to both orange and blue portals), so the energy is conserved between the portals. This energy, obviously, comes from the pillar upon which the orange portal resides, but of course, the mechanics of energy transfer with portals are wonky at the best of times.

once you get to high school, you'll learn kinetic energy is totally dependent on reference frame and isn't some actual value

Except for on the right.

Portals are PORTALS, not TELEPORTERS

Speedything goes in speedything comes out is true
therefore
not speedything goes in not speedything comes out is also true

It could literally be A or B depending on how the portal works. B would be the default, but A could be achieved, since the two portals need to know where they are in relation to each other in order to be connected, so they could act as a frame of reference for each other.

In other words, stationary blue portal knows that orange portal is moving in relation to it, as their relative positions are changing and therefore could potentially compensate for this.

But B would be the default behavior without the portals being specifically designed to behave like A.

You're just digging deeper.

>it's A, because A makes more sense under Portal's toon logic
Just because it makes "more sense" doesn't mean it's the correct answer. You seem to be neglecting something else that could happen. There's an option that takes into account the fact that the cube isn't moving, the portals can't change an object's momentum, and is actually what happens when you attempt this very scenario in the game's engine.

the orange portal moves instead of the box

because OP is right, in OPs pic the cube Has momentum since it is chasing a moving portal

Reality moved around the cube. You've essentially dropped a new location contained in hammerspace around the cube. The cube has no reason to move because it has gained no momentum from this action, saved for the shift in gravity causing it to slide down the slope.

These threads are fun because everyone who isn't a total moron knows its B, but then there is pseudointellectuals trying to explain it to blatant trolls and the occasional actual retard who earnestly cannot grasp it isn't A. I like to read pro-A posts and try to guess which of the two they are.

Not an A-fag, but the fuck do you actually mean? I mean, yeah, the gravity itself as a phenomenon is not a force, but its manifestation is a force in every sense of the word.

And how does that relate to the cube? It clearly exits the exit portal, despite it not moving. Therefore it has speed.

>The portal goes around the cube
That would have only made sense in the exit portal retracted as the entry moves into the cube. It remains stationary though. No matter how you look at it, the cube moves through the portal relative to the rest of the world around it, and it does so with a certain speed.

the blue portal isn't moving though, how could it go around?

is this what it feels like to be in an american public school?

You don't use momentum with moving portals in the game so those cases aren't accounted for in the engine.

then your gif and OP gif are two completely different scenarios
one has energy and one doesn't

What kinetic energy do I have when I am the reference? Are you retarded?

Per portal 1 we know energy is conserved moving between portals, ergo the space on either side of the portals can be seen as contiguous. The orientation of the portals is confusing you, it is simpler to think of it as if the portals were back to back and movement between them a single unbroken line.

A stationary object forced through a fast-moving portal would not gain the moving portal's speed. That doesn't make any sense. All the speed of the moving portal would do is cause the stationary object to appear on the other side of the portal more quickly. It's potential energy would be unchanged.

hahahaha you can't violate a definition what the fuck

See the gif in
The portals are only moving relative to how we percieve them. In actuality, portals are never moving relative to eachother.

by that logic, the cube would be ripped apart once it entered the blue portal

your logic is flawed and you cant be a theoretical physicist

I don't quite understand, but I'm picturing it as being like slamming your head at 200 miles per hour against a solid object

exactly, you can't violate a definition, so A is incorrect

Energy is always considered to be in reference to something else. Obviously nothing has 0 absolute kinetic energy but a stationary object will have 0 kinetic energy relative to another object. In this scenario, you're not saying that the inherent absolute energy common to both objects doesn't exist, just that it doesn't matter for the consideration at hand.

ok, then define a portal

Not in the slightest. In the original Afags argue that only the speed of the cube matters, so in this scenario this would translate to the gif in the OP. Bchads though understand that it's the relative speed of the cube to the portal that matters, meaning in this scenario, the cube should exit the portal at 1m/s

Yes

>An object isn't moving and has no momentum
>suddley has flyings at 1000m/s because lol why not

Why are people saying B? How is the momentum of the portal adding to the kinetic force of A?

is*

This problem is unanswerable unless we drill down exactly what is conserved between the portal entrance and exit. Is it 1) Kinetic Energy relative to a fixed observer or 2) relative momentum between object and entry portal.

The hulahoop argument suggests energy is conserved, shoot an arrow through the hoop and it exits with the same energy it enters with. It's also got the same momentum. But, two static portals on the ground suggest that Energy conserved but Momentum is not, since the direction of motion changes instantly upon entering/exiting the hoop. The space we're dealing with now is non-euclidean though, so it might be better to say that the apparent momentum between the arrow/box and the portal is conserved. If that's the case, energy need not necessarily be conserved though it would happen to be the case when the portals are static and on the ground.

This could allow us to explain what's happening when you make the infinite gravity loop: one portal on floor, one on ceiling, both static. When the box accelerates due to gravity it's taking gravitational potential energy, it conserves its momentum apparent to the floor portal, but suddenly there is new potential against gravity. In order for the box not to steal all of the planet's gravitational energy and eventually destroy the universe, the portal itself must donate this energy to do the work necessary to have the box exit the ceiling portal. So, energy is by no need conserved if we just take the apparent momentum between the object and the entrance portal to be conserved. The portals themselves source or sink whatever energy is needed to balance the equation. so to speak.

>Zig Forums pretends to be smarter than a Theoritical Physicist

portals are teleporters: A
portals are something other than teleporters: B

The game was not coded to compensate for the velocity of the portal itself, so in the current version of Portal 2 (the only game that can even have moving portals), A is correct. However, the developer states that if he were to design situations or puzzles where moving portals are to be used for actual gameplay beyond cutting pipes with a laser (which does not have physics, and is a simple killbeam), they'd implement functionality for the B scenario.

a hole in space, it's never defined as anything else

>the gif in the OP.
it's a fucking mess and doesn't understand the concept of inertia at all
the cube is not accelerating or experiencing any force, let alone how gravity is functioning in such an absurd scenario

A portal is just a different way point through space and time. And should not add or take away energy.

in one instance of time, the guy is exiting the blue portal via his own velocity however within that same instance he is being consumed by the orange portal's velocity
therefore he exits the blue portal in that instance with the combined
think about it, a slice of him is entering in an instance and then another slice is consumed so 2 slices exit with that same instance, meaning his velocity has to have doubled in order for those 2 slices to exit in one instance

the portal lense is moving only

you cant really be this dumb, you just contredicted yourself

who cares about gravity?

adding? enter at 10 kph, exit at 10 kph

only one layer is teleported at a time, all the previous layers need to be pushed out, giving them speed

But he enters at 5 km/h and leaves, through B, at 10 km/h

that makes a lot of sense, you might have just converted me to B faggotry

So, with this in mind it becomes clear that OPs gif is 99% correct, except at the very end where the cube rockets away at 1000m/s. This would assume kinetic energy is conserved if the portal is treated as a black box, but you can see the inconsistency - why would the top layer of atoms exiting the blue portal only be moving at 1 m/s if their energy is conserved? If their kinetic energy was conserved, that layer of atoms should still be moving at 1km/s. But if they were, and the box was rigid and indestructible, then these atoms would *pull* the next layer of atoms through the portal at 1km/s, not 1m/s, meaning that the second layer passed through the portal at effectively 1001 m/s instead of 1 m/s, thereby violating the conservation of energy that we deemed necessary in the first place.

Therefore, by reductio ad absurdum, energy is not conserved through the portals, momentum (in a strange and unfamiliar non-euclidean way) is conserved. In the OP gif, the box should exit the blue portal at 1 m/s, the difference in kinetic energy is stored in the portal itself. A is correct.

Pay attention in class, you're probably learning the concept of point of reference right now but you're too busy shitposting on a video games imageboard.

that's because the same objects in different reference frames have different amounts of energy but it's still conserved within the frame
please pay attention in physics class tomorrow

>But he enters at 5 km/h
5+5 is 10

*a slice of him is entering in an instance and another slice is consumed within that same instance so 2 slices exit the blue portal within that same instance, meaning his velocity has to have doubled in order for those 2 slices to exit in one instance
made it a bit clearer

I don't think you do.

Both are possible.

user...

here's why it's a:
the cube doesn't move
the cube moves to b
the cube still hasn't moved

lmao are you a fucking retard? Do you think cards on the other side of the road are going twice your speed too?

> exiting a portal doubles your speed
please fuck off from this life my friend
no such thing would occur

Nice bait. It's like what... a few hours?

This assumes that the energy is absorbed by the portal. Which is just fucking retarded and you should kill yourself for thinking that.

>You can't put portals on moving objects in the games, based brainlet.
The earth is already fucking moving you absolute shit sauce

As the stationary portal is the reference point, the cube enters at 10. If the moving portal is the reference point, the cube enters at 5 but the exit portal is moving backwards at 5 so the sum is 10,if the cube is the reference point, it enters at 5 while the portal moves towards at 5 so the sum is 10.

what could stop portals from absorbing energy, they're clearly fucky energy things anyway

user.......

consider A here is gibberish, B is correct
thanks for playing

How does the portal give another object the energy and force to propel upwards at 10km/h?

Who are you quoting?

Guess you think you're always "on the move" since the planet is moving too right? lmao you people are fucking retarded

Yes. See as well. The portals sourcing and sinking energy is an absolute requirement for even the base game portals to make any sense. You're the retard who apparently can't even read.

>the orange portal's velocity
in what universe does this matter, at all? portals don't give anything velocity, or change it, all that matters is an object's inertia relative to the portal

>stop portal one layer in
Now what?

Bfags have no answer for a point mass, and base all their spontaneous energy creation on misunderstandings about the behavior of rigid objects.
Do the problem with an electron instead of a cube.

A isn't gibberish, you're just not very smart.

did you read my explanation?
2 layers need to exit within a single instance (2 l/i let's say) but the guy is only moving at one l/i
enters at 1 l/i, exits at 2 l/i
his speed has doubled

Well said. Arguments over. Basically the way portal works is they're all the same room. Let's say a wall is moving towards you and there is a hole in the wall. If you jump through the wall you come out the other side at the same speed jumping in despite general relativity. So you see? They're just holes in a wall that leads to another place. relativity doesn't mean anything

you can't have a reference frame that both is and isn't moving, this is the basic paradox that founded the idea of reference frames in the first place

Portals are consistent "before" and "after: A
Portals are consistent at all times: B

>the graphic is what A suggests would happen
>take two whole posts to explain why it wouldn't happen that way
>conclude A is correct anyway
You mean B. You just explained why B is correct.

That's because you're an idiot.
>so they could act as a frame of reference for each other.
There is no "so". Anything can be a frame of reference for anything. You're literally just comparing two things. I can be a frame of reference for a train whizzing by. The train can be a frame of reference for me. A bird up ahead could be used for either of us. Or the ground. There's no prerequisite for being a frame of reference and it doesn't imply any form of similarity. It is literally just a matter of which perspective you choose to observe a system from.

You patently do not know what frame of reference means.

ITT: liberals try to convince everyone that the sky is green and not blue
cognitive dissonance as a weapon?

general relativity and relativity are two separate things you blithering moron

In what frame of reference is it conserved?

rotate the square clockwise 90degrees in the second frame.

A is the right answer and B is the wrong.

im not saying he's wrong, im saying he proved that he is dumb in regard to his previous statement, or i just misunderstood it

bad b8

>ITT: liberals try to convince everyone that the sky is green and not blue
>cognitive dissonance as a weapon?
what did he mean by this?

I can't imagine being so monumentally retarded. I'd ask you to try and explain it but I wouldn't want to take up your single brain cell for so long.

reminder that portals straight up change objects' velocity ingame
if you disagree then you don't know what velocity is and need to remove yourself from the discussion

>Portals can't be attached to anything non-stationary
>Except the moon because that doesn't count for some reason
A fags, everyone

How do they give potential energy? I don't know. Science? Praying real hard to Mr. Dawkins? A generator attached to Newton's coffin?

The robot is lying to you, user. It's all a test.

what does that have to do with A fags, the portal is moving in both A and B
if anything that's a C fag scenario

Both scenarios change the cube's velocity!
ffs, you retards keep saying the same thing and not listening.

see
it matters because of the effect it has the the guy's rate of exit

It's a. Just because something goes through a doorway doesn't mean it magically gains momentum because "cake game physics" or some shit. Bfags are absolute fucking idiots.

>Earth doesn't move

Hitting a stationary car at 40 MPH has half the force of two cars going 40 MPH crashing into each other (head on)

but if the planet stopped moving abruptly you'd be flinged into space(or the ground depending where you are), which means you're constantly on the move even if you're not moving relative to the planet.

If the energy is absorbed by the portals, they should exert that energy back when you make new portals, causing everything around it to absorb the energy. If they don't, you assume energy gets destroyed. Which you know, energy can't be destroyed.

So you are retarded and a minimum wage worker.

Depends on how you think of the portal.
If you're an AChad, you consider it sort of a hole in the universe, like a hula hoop.
If you're a BFag, you consider it a transitionary barrier, so if you imagine the bits on one side of the portal are pushing the molecules that entered before them.

So this means a Bfag would believe that in the scenario I have edited in paint, the portal platform travelling downwards slamming down on the platform would "suck" the green box through, while AChads believe it is simply a gap in the universe that will not interact with the box which will continue to rest in the snug little hole.
This also means Bfags must believe that the durability of entitites travelling through a moving portal must increase with the speed of the portal, as the method of acceleration would literally attempt to rip the entity apart. So the box must be assumed indestructable if it is to get Bfag "sucked", while the durability is irrelevant to AChads.

The earth one could be argued as "Not moving relative to one another" so I jumped to the example with less arguments possible

stopped moving relative to what?

Yeah you're right. Take that out of the sentence and just say relative speed

As a bfag, I agree with this, there are no contradictions and it is simply a logical extension. Don't see an argument against it though.

You're not understanding. The reference frame is not moving. The reference frame is some point of folded/distorted space in between the two portals. Both portals can have their own reference frames, but unless the portals are specifically designed to work like B, those reference frames are irrelevant. In A, the one that matters is the one in between the two portals. That's the one that determines the momentum of the object that comes out of the portal.

You are literally describing reference frame exactly how I'm using it, and then claiming I don't understand it.

Let's pretend for a moment that, just as you suggested, there is a train whizzing by, and you are the reference frame for it. Let's assume the train goes through a portal. The question is how is that portal designed? Does it just send the information of the object's momentum directly from one portal to the other? In that case, it would be B. But it's not necessarily designed that way. You, the reference frame in this example, could be holding some kind of beacon or transmitter (like, say, a Portal Gun) which detects all objects entering the portal, and their location relative to yourself and that portal, and then sends the correct information to the exit portal with additional knowledge of what's moving relative to what. Insisting only B is possible just means you're making assumptions about how the portals work that aren't necessarily true.

relative to the sun, for instance.

RELATIVE MOVEMENT = portals moving relative to each other

There is no other meaningful statement worth making, stop fucking talking about earth's rotation or whatever dumb shit floats through your empty skull.

Seems like a lot of mental gymnastics to try and get B to make sense then.

You can just google the word velocity to prove what you said to be fucking wrong, embarrassing.

Any Afag that actually says the word 'hulahoop' is just a Bfag falseflagging, or is a retard equivalent to for Bfags

Portals change the position of an object and conserve its momentum. There is the speed which an object moves through the portal, but that can't particularly count this as speed or velocity applied onto the object because the object moves from point X to Y in a matter of time that is effectively 0, and considering its happening theoretically we can't say its not possible in a divide by 0 situation, and thus must conclude its happening with infinite velocity.
But this infinite speed isnt applied to the object, because it conserves its initial velocity and momentum after it fully exits the portal; the infinite velocity is merely a byproduct of it taking a 'shortcut' from X to Y.
Therefore, A is correct, because the velocity of the portals is irrelevant to the actual velocity of the object, because the object is sent through the portal at infinite velocity regardless of its own velocity.

>stop thinking about the whole scenario of the problem, PLEAAAASE.

>applying real world physic laws to a video game

That's the most fucking retarded assertion that B fags for some reason take as gospel.

>don't worry bro the gun and portals just contain an infinite energy supply
Shut the fuck up you midwit pajeet. If you can't see why this rebuttal is stupid you don't even deserve another second of my time.

After reading these threads for years, I've come to the conclusion that Bfags are literal children and pseudointellectuals that read about relativity once and think they understand it. Read about the twin paradox Bfags, you can't just simply say that you hitting a car at 60 mph and a car hitting you at 60 mph are the exact fucking same. Portals also provide an objective frame of reference in a sense. A is right.

can you tell me where dx/dt is incorrect here retard?

Surely someone has already made a map of this to see what happens.

1 is functionally a hoop and it works for B since the entrance and exit are always relative to each other
don't use it or hoops or holes or whatever to argue for A because the outcome is literally the same for B
one portal having different momentum is the whole point of this thing

Attached: 12.png (331x435, 841)

Retard.

the twin paradox is speed relative to earth vs speed of the rocket you retard

Achads: "ah yes, occams razor"
Bfags: "no0o0o0o0o0 I haffta use da video gamm to show girls whye I browse r/iamverysmart"

the box is fucking moving relative to the blue portal (which isn't moving) at a rate equal to rate it's being consumed by the orange portal (aka the velocity of the orange portal)

>the absolute state of the jannies

If you walk through an emancipation grill while holding the portal gun, both portals disappear. This proves that the portals are not isolated systems. The portal gun acts as a third point that can be used as a reference frame in determining an object's velocity relative to the portal.

And A was correct, but bfags cant accept they are wrong and argue that the game wasn't set up for that experiment

lmao how the fuck was this not Zig Forums

Then what's the fucking point? We're talking about how it would work, why does the result of the game not matter?

I don't get this. Are you assuming that portals have matter and therefore can store energy? Because if you do, you are retarded.

Photons don't have mass, but they have energy and momentum.

>unable to apply mechanics of one situation to another
>NOOOO YOU'RE WROOOOOONG

B makes literally no sense. Suck my dick and choke on it, as my dick enters your portal of a mouth I'm sure it'll shoot off to light speed, faggot.

tranny janny

>Bfags literally had to move the thread to Zig Forums as a last ditch effort

kek

According to the way the game's portals work, it should be A.

absolutely braindead. see , for starters.

But A fags argue that portals are interconnected wormholes that dont move relative to itself, and only the surface on which a portal is placed is moving. B fags on the other hand assume the portal itself is moving relative to the other portal. Its a diverging path and the outcome of the speculation is different if you base your assumptions on Afags theory or Bfags theory, neither are wrong and neither are right but the will continue to preach about their infinite wisdom anyways, unaware that they are both dumb and dont understand theoretical science.

Exactly, A-fags can’t accept that the moon demonstrates B in game (Chell must inherit the moon portal’s velocity or be violently shredded). They also can’t accept developers being on record saying they’d code it as B. The best they have is hacking the game to show some non-functional code “proving” A.

Because Bfags cant accept it

>The duality of man

Fucking kek

>(Chell must inherit the moon portal’s velocity or be violently shredded)
What are you talking about? Why would that need to be the case for A? You're literally presupposing B and then saying that your own presupposition proves itself.

Photons don't store energy though. It always carries energy. The problem here is that Bfags assumes the portal magically takes or adds energy.

brainlet, saying Chell 'inherits the moon portal's velocity' is a conservation of momentum argument, which is A not B.

>these idiots believe light can take away energy
HAHAHAHAHAHAHAHAHHAAHAAAAAAA

If I stick my hand into the middle of an orange portal, while the blue portal is moving at a rate of 1 mph, does the orange portal magically move? My hand isn't fucking moving, the orange portal isn't fucking moving, why would you get ripped apart?

Photons can have different amounts of energy, you absolute retards.

If Bfags are to be believed, any object entering a portal would be obliterated beyond atomisation.
They may claim that the molecules that go through first are being pushed by the molecules that come after but why does a portal respect "molecules"?
What if a moving portal subsumed HALF of an atomic nucleus? By the logic of Bfags, this would mean that one HALF of an atomic nucleus is literally pushing against the other HALF of it. This would of course destroy the integrity of the nucleus.
And, as there are no "frames" to reality, we can assume this happens to every atomic and subatomic particle that travels through the portal, at some minute point in time, half of the atom is being pushed into by another half of the atom, literally ripping at the structure of said atom.
So while Bfags CLAIM a box will come flying out, they are simply wrong. By their own logic, anything that travels through a moving portal would be annihalated on a subatomic level, and there would be no box output, only radiation.
I would put black people through as a test.

I’m working under the assumption that A’s position is “portals can’t impart velocity to objects, other than changes in direction”. State your definition of A, then.
