the blue portal is also in motion with respect to the orange portal, therefore A, dumb brainlet

Reminder that the concept of an “external frame of reference” doesn’t mean shit in Portal physics, the only frame of reference that matters is the one of the object entering the portal.

>Let’s say I put two portals 1000 feet apart, and walked through them. To an outside observer, in an external frame of reference, I have moved 1000 feet in the span of the fraction of a second that it took me to pass through the portals. Therefore, I must be said to have a velocity of several thousand feet per second, and should logically begin flying forward like a bullet as soon as I exit the portal. At least from that outside observer’s frame of reference.

The cube isn't moving, you fucking dumb ass.

Don't get me wrong, my dude. I'm not saying that my pic is an analogy for the original problem. Not at all. It's even better than the original problem, because there's no """paradox""" — it can be 100% irrefutably solved (as pictured) just by using incredibly basic concepts, and yet people STILL cry about it.

Fuck, I really actually do have to go to the store. I've got shit to do. This thread will probably be deleted when I get back, so bye friends.

>Afags are chads not doubting themselves
>Bfags need to be considerate and emphasize that they are just going by what we know about science and logic, not trusting that an answer can speak for itself

The whole situation makes no sense from the POV of physics from the outset. The whole problem arises from a fundamental misunderstanding of the concept of a frame of reference. To make the problem apparent, you should consider a situation in which your observer can simultaneously observe the cube on the platform (A), and the cube through the portal (B). The way the videogame does things is by creating a 'copy' inside the portal, and it's properties are defined by the cube 'not through the portal' AFAIK, so it avoids the problems that will unavoidable arise. But if this wasn't the case, our observer has to believe that these two cubes are the same, one item, with the same properties that are /defined by the frame of reference/, like amount of speed, potential energy, etc.

This is all very believable while things are motionless because the same theories that apply to objects in mirrors apply. The second the platform moves it all breaks down. Suddenly cube B appears to move towards the portal, meaning it has a nonzero amount of speed while cube A is motionless according to our frame of reference. If cube B were to successfully cross the portal before we even consider the cases in the picture we must acknowledge that the amount of potential energy of cube B possesses has changed (since it's at a different height from it's starting position),this can be explained by whatever work was done to move it towards the observer. But cube A had no work done on it and therefore should have the same amount of potential energy as it had at the beggining of our thought experiment. So despite the fact that we're to believe that they are the same object, in the same frame of reference, we have two contradictory accounts by one same observer.

REMINDER: Conservation of energy/momentum in the normal sense only applies in continuous, flat euclidean space. The portals introduce a discontinuity, so arguing for A in terms of conservation laws is nonsense.

Shut the fuck up and let me take refuge from the star wars and waifu threads.

>my minions
Of course Bfags are all sheep

The problem only gets worse, but simpler to understand if you have two observers in different rooms, and the portals actually connects both rooms. In one, the observer watches cube A sit motionless on the platform with the other platform coming down on it. In the other one, the observer sees the cube rising towards him. One of the observers will conclude that, since cube A had a constant zero speed throughout the whole process, that it will probably have speed of zero upon emerging from the portal (the 'hula hoop' interpretation). But the other one, who can measure a net speed for the cube throughout the whole process can clude that the cube will have a net speed immediately upon emerging from the portal (the 'launcher' interpretation). Neither of them has any way to measure the events on the other room and both have empirical observations supporting both of these interpretations, there's nothing you could tell them, from the point of view of physics, to prove them wrong.

Yes I am reposting this because the other thread died

How come Afags can't understand basic relativity?

And Afags are virgins

This is already true in the actual game, with static portals. I don’t know why people act like it’s a revelation.

Put two portals in a room, one near a box and one far, and stand between them. Now, move toward the portal away from the box, and MARVEL IN AMAZEMENT as the box visible “through” the portal moves toward you while the actual box also moves away from you.

It’s a “paradox” but never counterintuitive in the game space. Nobody thinks its weird, because it’s understood that a Portal represents a path between noncontiguous space.

The cube itself it not moving into the portal, its being projected through the portal in an unnatural manner while having no movement what so ever, as the orange portal moves towards it. If the image was flipped 180 degrees, you would have a point. As it stands, it's A. The cube is motionless, the things around it are moving. The cube doesn't start moving ujtil going through the portal,and either flopping to the ground or getting jettisoned.

>OUR perspective

You're a dissappointment is what you are. I'll need you to hand in your passport, your gun, your other gun, and your hamburgers by 6 PM eastern, at which time you will be put on a flight to europeistan. God bless Trump.

By creating a portal you have reduced the distance. According to your logic though I'm currently moving at absurd speeds just because the distance from my chair to the moon and back is huge and I'm currently sitting, so traveling from my chair to my chair.

>Portal doesn't touch the box
>The box gain's the portal's speed
??!?!?!?!?!

is this the most complex dilemma that Yea Forums will ever face?

>That fucking wall of text
>"It makes no sense from the POV of physics"

You underestimate the power of modern physics. Just model it as a piecewise euclidean space with one piece, A, being most of the room, and the other piece, B, being the immediate space around the portals. Define reference frames so the room is still in reference frame A, and the joint "Inside portal" space B is still in the reference frame B. Momentum conservation holds in A and B, but has no reason to hold in transformations between A and B. Now we see that when the orange portal moves in A, the cube moves when we transform its coordinates to B. The collision between the orange portal and the platform in A corresponds to the PLATFORM, and only the platform, suddenly decelerating in B. No forces act on the cube to keep it stuck to the platform, so by momentum conservation inside B, it keeps moving. Then we transform the cube's coordinates back to A, where we see that the cube is moving away from the blue portal. Boom, solved, it's B.

All inertial frames of reference are not equally valid when dealing with a portal through noncontiguous space. The game makes this abundantly clear and you’d have to be retarded not to understand it intuitively.

But if I cut out the left half of the image and Looked only at the right, what would I see the cube doing? It is moving. It is moving out of the portal and perpendicular to it, and should continue doing so unless acted upon by an outside object or force. Basic newtonian shit right there.

B and it's not even close

Does the game itself ever make jokes about Portals breaking all Laws of physics and being impossible?

What the fuck are you talking about? Let and right are different directions you fa—

Okay sorry, you're saying that from the cube's perspective it just continued in a straight line through warped space. I get that. I'm not really sure how valid that argument is, but it's how things "look" when going through portals, so, fair enough.

>Claim without evidence is dismissed without evidence
it doesn't, because in his example both portals are stationary with respect to each other, while the cube is moving, so the momentum conservation applies.

in the op, the blue portal is stationary with respect to the cube, so if you change the reference frame then not only the cube but also the blue portal are moving upward with the same velocity, which makes it A

There are no forces acting upon the box, why the fuck would the box gain 10 m/s???!?!?!

kek

I haven’t reduced the distance from the frame of reference of an outside observer. To them, I am very clearly traveling thousands of feet per second.

Either my frame of reference as the person passing through the portal is “privileged” and correct, or the game is fundamentally wrong and any amount of portal travel should impart an exit velocity.

>All inertial frames of reference are not equally valid when dealing with a portal through noncontiguous space.

You're in charge of Portal 3. What does your reference to these arguments look like?

There never has been an unmoving frame of reference, what we call 'stillness' is merely the fact that some objects don't move relative to us (the ground, for instance).

>I haven’t reduced the distance from the frame of reference of an outside observer.
The portals are in the same frame of reference.

This entire thread is fucking stupid.
> one side of the portal is moving, the other is not
This scenario isn't ever created within a Portal game, outside of the singular time we used it to move lasers around, wherein both portals were kept far from the player or any physics objects.
Some part of me wants to say A, because the box itself doesn't have any of its own momentum, but then I thought a little harder.

A situation where everything, including your point of view, is moving relative a stationary object is indistinguishable from a situation where that object is moving through the universe as we normally think of it.
In a scenario where the fabric of space itself (E.G. a portal) is moving, a stationary object would gain all the properties of a moving object, including momentum for the purpose of being conserved.
Check and mate.

How would the box come out of the blue portal without moving up out of it? You can't come out of a hole without, you know, coming out of the hole.

Nigger please stop being dumb, this is a no dumb area. General relativity doesn't give momentum to objects at rest. General relativity merely tells us that from the perspective of an object in motion an object at standstill appears to be moving. Hence the term RELATIVITY

Momentum exists whether an object is moving through the universe or the universe is moving around a stationary object. This scenario is the second case.

The box isn't moving only the space around it.

But you've made an error, the important bit is that whatever unified interpretation of the events needs to hold at all times, you can't change your frame of reference to B, draw a conclusion and say it must be true in A, I would suggest that you would do the opposite, observe that the conclussion is also opposite. Whatever analysis must be consistent at all times, that is to say you must be able to switch back and forth between A and B at will and draw the same conclusions.

What a retard. He's wrong.

No. All frames of reference are equally valid. The one occupied by your ass is not special.

>ignorant gravity
>ignoring conservation of momentum
>ignoring newtown's third law
>All because you're a communist hippie who thinks that the portal thinks the cube is moving therefore the cube shoots off into space

Doesn’t matter. In any real-life physics situation, an object cannot travel 1000 feet in a fraction of a second and in the next fraction of a second be stationary, unless an external force acts upon it to stop its momentum. But this is indeed how every single portal in the game works. You travel large distances in a short span of time without being accelerated to great speeds. Therefore it stands to reason that a portal represents a connection between noncontiguous points of space that can be traversed WITHOUT MOVING. It is as it appears from the perspective of the traveler; the space is connected, no meaningful distance is traveled.

This invalidates the frame of reference of the outside observer, but we do not care, because that is how it works. A portal allows displacement of an object without movement, without velocity.

It should stand to reason that the same rule applies to a moving portal; as the portal moves over you, it translates you through space WITHOUT MOVING YOU, because movement through a portal has nothing to do with velocity, momentum or speed.

Moving objects are not the same as moving space. More like "take the fabric of space and drop it over yourself and experience the force of being thrown 1g upwards as it drops".
If the cube doesn't move, then it can't come through the doorway without BOTH ENDS OF THE DOORWAY moving. Only one end of the doorway is moving.

Oh wow very genius I guess it does make sense if you ignore the entire experiment and only consider the possible results, bravo!

As long as the transformation from A to B is defined consistently, i.e. all points in A map to PRECISELY one point in B, and backwards, as well as all velocities at points in A and B being one-to-one in the same way, then yes, you CAN solve problems that way. In fact, that is HOW you solve this type of problem in physics.

You still haven't explained how the box could emerge from the blue portal without moving with respect to the blue portal.

I’ll keep repeating it: if you place 2 portals 100 meters apart, and then step through the first one, do you exit the other one at 100m/s (or more)? No? Why not? After all, to any observer in an external frame of reference, you’ve just traveled 100 meters in the span of (less than) a second.

But this isn’t how the game works. So then any frame of reference external to the person traveling through a portal can be discarded when it comes to their movement through a portal.

Have you not seen clips of those kind of games with a camera fixed to the moving wall? Does the camera see the person standing still or moving towards it?

Alright let's rephrase this for retarded Afags (oh wait that's redundant)

Let's take the instant one nanosecond before the cube is all of the way out of the blue portal. Only one layer of atoms from the cube remain to move through.

To make way for this last layer of atoms, what does the rest of the cube have to do? MOVE AWAY FROM THE PORTAL!

Now, practically the entire cube is moving one nanosecond before the entire cube is through. One nanosecond later, there is no outside force or object that will prevent it from moving, so according to newton's first law IT MUST CONTINUE MOVING (until gravity brings it to a halt). END OF.

Seriously, how do Afags not get this? Is it retardation or what?

but it's literally a....

Movement through the portal is undefined in A, precisely because you can't consistently model a portal using a single reference frame. Even Valve figured that out, THEIR portal physics relies on a solution like this.

>Resorting to ad hominem
Dude, I'm just trying to give you an example of something you easily relate to.

"Real" wormholes are spherical and behave as B. The cube viewed through the wormhole is moving, it does have momentum.
Also, Newton says B too, because of conservation of momentum plus locality.

>this is your brain on B
There is literally no reason for the water to fall in, retard.

I think this image is flawed because 1 m/s water flow pretty much would "plop" unless there's no gravity. Make it faster to get the point across. Realistically, with such a low flow speed, both "A" and "B" treatments of the problem would just end up with varying degrees of "plop".

It's literally a pump man. You're pushing water through a hole with a measured force. Of course it should shoot out.

Explain how it can't be moving, yet hit something that is also not moving.

AFags are literally seething and crying every single thread. It's fucking hilarious and I love it.

If both portal are underwater there wold be no pressure difference and no acceleration.

You can’t create a “shortcut” through contiguous space in real physics. In real physics, in real space, all space is defined to be contiguous. This is why time dilation happens.

Portals break this down. Portals create a situation where a distance can be traveled in a given time WITHOUT the necessary velocity to move that distance in that time. We are presented with a (relativistic) paradox; a situation where a distance can be traveled at a speed without moving at a velocity that would allow it.

This completely destroys the concept of an “inertial frame of reference” across portals.

But your argument relies on transforming to B after somehow completing the entire move through the portal in A. which is the ONE movement in the entire system that isn't allowed.

Now post the gif

It’s not moving, it is being phased through fold in space and time. The cube is a stationary object with no kinetic energy.

I still think your argument still fails one moving through your B (space immediately around the portals), moving through the portal in this frame of reference produces a discontinuity in terms of potential energy, not to mention the quantifiable work while in B does not equal the diference of energy one measures before and after in A.

What's your point?

The “hula hoop” argument is a poor articulation of the same concept, but it IS the same concept: a portal displaces an object, it translates it through space, without MOVING it.

An object that passes through a portal cannot be said to be moving, in the traditional sense. It is ceasing to exist at one point and beginning to exist at another, instantaneously. This is why portals allow you to travel hundreds of meters in a second without imparting a velocity of hundreds of meters per second.

Thus, moving a portal over you IS, in a sense, like dropping a door frame around you. You are not actually MOVING into the space at the other end of the portal; you are being placed there. You are stationary relative to ALL the objects in that space before the portal reaches you; as it passes over you, it’s like the laser in a scanner and the write head on a printer, displacing more and more of your body from one space to the next. It isn’t MOVING you, though it may appear this way, because passing through a portal is not the same as moving through space. It is, as mentioned, simply ceasing to exist in one place as you begin existing in another. No movement occurs, no velocity exists. The game demonstrates this repeatedly.

A cube that is stationary relative to its environment will remain that way, regardless of the speed of the teleporter flying across it.

>So you admit that the blue portal moves with respect to the box, i.e., the box moves with respect to the blue portal which is stationary in the frame of reference in which the diagram is drawn, i.e., the box moves in that frame of reference as it emerges from the blue portal.
Right, but neither are moving, so in the end they're still not moving.

A wins.

I've got to say, my dude, the concept of space itself "moving" around us implies a privileged frame of reference, i.e., that of space itself, which goes against modern understanding of physics, namely relativity.

I don't know if you're wrong about what you're trying to say, but I think you worded it badly.

Yeah, it does produce a discontinuity in potential energy. That's allowed for portals in the game itself, and in exotic metrics like this one in physics. Energy conservation only holds in t-symmetric spacetimes.

The distance is the same. 2 portals 100 meters apart are 100 meters apart. Passing through a portal relocates you across that distance without moving you through space.

You were BTFO by . You can stop posting now.

if B happened wouldn't the cube tear itself apart since it is both stationary and moving while being on both sides of the portal?

Then what is a portal if not moving space?

Look, maybe you'll say this is still the same on some level, but the usual "hula hoop" argument is much dumber than what you posted. It basically takes the portal, whose entrance and exit are moving with respect to each other (which is the entire point of the problem), and replaces it with a hula hoop, whose entrance and exit are, by definition, not moving with respect to each other (thereby defeating the entire point of the problem). Put more simply, the typical use of the "hula hoop" concept in Portal threads is for an entirely false analogy. Sometimes it's out of stupidity and sometimes it's a deliberate attempt to bait people by "simplifying" the problem until it's actually a fundamentally different problem with a different answer.

funny i was playing portal 2 a few moments ago.

I'd say that the distance between 2 portals is already 0.

>this tired bait
why are hoopfags so dumb, bros?

Exactly. That is what makes physical sense, part of the cube is carrying the other part of it, pulling on it.

I mean, one way to define the discontinuity in space caused by the portal would be that points on the "surface" of the portal have a degenerate measure of distance, ds = 0 and ds!= 0 at the same time

Yeah, it doesn't make any sense.

I don't know man, it's just relentless stupidity

So the box is not moving, and then it is moving, and then it's not moving again. Hmm. The transition from "not moving" to "moving" is mysterious, sure, but the subsequent transition from "moving" to "not moving" occurs after the box has fully emerged from the portal, so there should be no more portal fuckery, so there's no excuse for disregarding the concept of inertia.

According to this logic, if I move a piece of paper through a portal quickly and stop half way through the paper should rip in half. Chell would have died multiple times in the game if that was the case.

Only if it didn't have enough tensile strength.

A if the amount through is such that the momentum of the part that's already gone through is less than the gravitational force of the part remaining, otherwise B.

See above

You'd be hurt pretty badly trying to "quickly stop" fast enough in normal space too, though. Jet pilots have died from the g-forces involved in stopping too fast.

>this kills the plan b accidents

Portals work like windows through space, not by moving spaces around. Hoopfags are literally correct.

No you imbecile, because in the in-game situations portals aren't moving, they aren't creating momentum ever.

No, it never moves. It's only moving relative to the blue portal, and vice versa, which also never moves.

Works both ways. Wouldn't the cube be crushed as it enters the portal, since it can't be moving and moving at the same time?

That's not have physics work, you mongler retardo. Fuck sake.

>you can move one side of a window without moving the other
Hoopfags are literally this stupid

The hula hoop argument is an attempt to articulate the intuitive sense of what I’m stating; that a portal being dropped on you is the same as the room it’s connected to being dropped on you. That’s what is happening; the portal moving down is, for all intents and purposes, the same as the space it’s linked to bearing down on you like a train, and slamming to a halt as you pass through. You don’t gain momentum from this.

The intuition that makes people think B is right is that from the perspective of an observer watching the exit portal, the cube appears to be flying toward them, and thus have momentum, so they assume that it must.

My argument, essentially, is that the appearance of momentum, of velocity, across a portal, is a misconception, a failure of intuition which we derive from assuming that a change in position over time = velocity. This is what B believers assume must be true, that a portal must follow the basic rule that delta-position over time is velocity, but of course if it WERE, then crossing any portal would accelerate you to ludicrous speeds.

The game teaches us that crossing a portal is not the same as moving a distance in real physics. It stands to reason that a moving portal obeys the same rules; translation over time without momentum.

>It's only moving relative to the blue portal

So it should keep moving until it is acted upon by an outside force or object.

it depends on whether the space inside the moving portal is moving with it. If it is then from the perspective of the other side of the portal the box is moving instead and inertia would send it flying.

newton
einstein was a hack that stole his theories

No, because it's not moving.

So you're saying the distance inside the portal itself is non zero? I don't get what you're trying to say.

how does anyone look at this and say "B"? jesus christ. have you never interacted with anything in real life

But you just said it was moving relative to the blue portal. Which means it's moving.

This breaks the laws of physics so it's not even worth arguing about.

People don't actually think it's b right? It's just shitposters right?

The part that has emerged from the portal pulls the other part out of it, bleeding momentum to do so, provided that the box is strong enough not to break. If the stop occurs at exactly half the length then the box flies out at half the initial speed.

The distance inside the portal is zero, in the same way that the distance between the two sides on a window with no glass is zero.

What makes it stop moving relative to the blue portal?

So it's moving but not moving at the same time?

Attached: tfw too smart to believe jews.png (645x719, 52K)

That might be relevant if the object was moving, but it isn’t.

But since you brought up g-forces, here’s another thing.
If you were sitting and and a portal moved over you at 10m/s, you would not instantly accelerate to 10m/s, you’d just switch locales and potentially be impacted by sudden change in the direction of the gravitational pull.

Further, the light entering a moving portal does not suddenly magically travel faster than light once it exits the portal.

Portals are literally just folded space. A fucking hole.

You seem to be under the impression that the body can't withstand being pulled in two different directions with a acceleration differential of at most 2g
You can create much stronger forces than that just by grabbing your finger and pulling it.

It never went in the first place. Again, neither box nor blue portal ever move.

One portal moves relative to the other
This would be like one side of the window falling on you while the other side floats above your head
That's not possible because windows, hoops, and door cannot physically do this

I think I understand why some people are misunderstanding so much. Both portals are the same portal. It isn't different portals connecting with each other.

Of course. The tiny box is moving relative to the big box, and vice versa, just like the blue portal.

The true red pill is that the portals never more, space moves around its fold.

Attached: 1559852185820.gif (250x250, 222K)

The problem is that both ends of the vagina are attached to each other which is not what this scenario is.

Okay, let's consider the middle of the problem, taking t0 as the moment the box starts going into the portal, t2 as the moment it's all the way through, and t1 as the point between.

at t1, the edge of the box that was facing upward is in a position. At t2 it is in a different position. Therefore, it had to move. And as an object that is in motion, there is little reason that it should cease to be in motion considering that there is no outside force or object to act upon it.

Would that tiny box stop after the big box stopped?

what if the portal was accelerating at 90% the speed of light towards a flashlight shining into it?

Except they do, you clearly don't know what momentum is.

This doesn't happen though. 'Though' is only relative to the box and the blue portal, which again neither are moving.

Here's another thought experiment to better explain this, and why people who believe it's B because of "inertial frames of reference" are wrong.

Presume you are standing under a grate or hole that will halt the Orange Portal surface, but can look through it to see a cube on the other side. From your perspective, that cube through the portal "has momentum", and is accelerating toward you.

When the Orange Portal surface slams into the stoppers, from your frame of reference, the cube on the other side should continue to move toward you, and thus should be bounced or bumped up off the floor of the other room, toward the Blue Portal on the ceiling, with the same force that the Orange Portal surface had when it slammed to a stop.

Do Bfags believe that this is what would or should happen in the Portal universe?

I highly doubt it. Thus we can conclude that the observation of "momentum" across a moving portal is merely a failure of perception.

Its not just semantics, relative momentum is the main topic of discussion here.
If you're looking into the blue portal, the cube is clearly moving, while if you look directly at the cube, its still.

>'Though'*
*through

But there's a reason we aren't flying awat dumbass. Gravity cancels out any momentum we have. Thus make us have a net of zero momentum. Unless you want to include the speed of the planet, solar system, galaxy all in terms of our place in space. As I said, draw the fucking diagram already.

It's not going through the portal so no, it's not moving and carries no momentum.
Congratulations, you failed to completely understand the point of the experiment.

>Semantics

this is without a doubt, the dumbest thing I've read on Yea Forums.

the tensile strength of your body is such that you would feel your dick tugging away from you but it wouldn't come off, doesn't invalidate B.

>which again neither are moving.

Even though you said earlier that the box was moving relative to the blue portal?

Let's suppose we stop the process halfway and record its position on the blue side of things, then start it up again and record it again. Most likely it will have changed. That is movement.

>Spacetime moving.
Two questions then:
Why does the tiny cube only start moving after the other cube pushes it if spacetime moving is somehow giving it momentum and not the big cube?
Now replace the tiny cube, with the big cube being already 90% through. Why would the 90% not gain momentum from bottom 10% pushing it?

You should be able to answer this.

I'd like a Portal game, not a Portal 3, that is basically like the 50s part of Portal 2, but live. The rooms are clean, the bottom is water instead of acid, and this is early on, so Cave Johnson is actually doing live commentary, instead of it being a recording. Make it about 30 levels in length, and include early versions of everything in Portals 1 and 2, as well as some other old stuff. Also, while you're too far for Cave to hear you, add a hand gesture system which Cave will react to, like asking how a certain part was, and getting angry when you give him a thumbs-down.

the rules for stopping halfway have been covered herehow

>agaisn't
nice, just noticed that

>Even though you said earlier that the box was moving relative to the blue portal?
Right, because when you're moving spacetime, relative positions in spacetimes are irrelevant. That's the whole point, which I'd hoped you'd figure out.

It doesn't have to be going through it, IF we are going to argue that relativistically speaking, there are no privileged frames of reference. From the perspective of the observer on the orange side, EVERYTHING on the blue side of the portal has momentum and is coming toward him. That momentum should be conserved until a force acts upon it to stop.

The only way we can conclude that this is not true is if we reason that the movement of a portal represents the displacement of space over time WITHOUT velocity; that the portal moving toward us is bring the space on the other side closer to us WITHOUT MOVING IT.

Once we acknowledge that this is true (and it must be), then we have to acknowledge that the same rule would apply to an object passing THROUGH the moving portal; it is being displaced over time without being MOVED, without altering its velocity.

>how
Because vacuum

So what if the portals "tear your head out" if they're moving? Is that the argument against B?
Because then that means that one argument tries to make physical sense of the situation, while the other tries to make narrative sense.
If the laws of physics should dictate that your head is teared off should a moving portal approach you, then that's what going to happen, even if you don't want it to be that way because it sounds gruesome or doesn't sound intuitive.

still not a hoop

>Why does the tiny cube only start moving after the other cube pushes it if spacetime moving is somehow giving it momentum and not the big cube?
Because the big cube is now occupying the space where the tiny cube is, and something's gotta give as it were.
>Why would the 90% not gain momentum from bottom 10% pushing it?
Because the bottom 10% isn't pushing it. The cube, in it's entirety, is never moving.

Thought experiment time: pick a spot on the cube, and follow it as it goes through the portal. At one point, its at ground level, and moments later, its above that height, meaning that point on the cube is moving whilst NOT moving, since it has no momentum. Its both moving, and stationary. How can this be?

Because portals translate you through space without moving you.

You mean almost exactly what happened, when accounting for the fact that only a finite amount of air can pass through a hole at a time?

the cube is never in motion you autist

>two ends of an infinitely short tunnel with no measurable length
>not a hoop

Because warping space is different from moving.

Sure it is. If we look at the point when it starts going through and the point when it stops, and we're looking at the blue portal, we will see the cube moving out of it. It is in motion, this is a fact.

Then if it's not moving, it should never come out the blue portal correct?

Then, operating as a translation insteadof movement, if we had a plank of wood covering the blue portal, would it be launched by the force of the crusher, or merely pushed out of the way?

The 90% are occupying the space where the bottom 10% are, so it's basically the same as the tiny box scenario.

Look a , imagine that fold in space being unfolded and folded repeatedly, now focus on the A and B points. A and B will get closer and further as space folds, even though their points in space never change (ie, they don't move).

Oh, and at the end, you could just leave, but he would tempt you to try one last puzzle, with the rules of it having already been mentioned in your contract. It would be super hard, and at the end you would fall into a chamber that would freeze you, so the character could appear in a potential Portal 3.

It wasn't moving but the space around if did.

Proof by contradiction doesn't work on Afags. They will cling to laws that never applied to portals in the first place, even in the face of mathematical impossibility.

Merely pushed out of the way.
This is an interesting argument. I guess if the orange portal was moving fast enough, it should flatten the cube into a tiny paper-thin disc, since it would be displacing more and more of the cube into the same space.

Of course, here we can lean on the "dual forces of gravity" argument and say that for the speeds we're talking about, the structural integrity and natural elasticity of the cube would be enough to have it sort of pop into shape on the other side as more of it was brought from one location to the next.

I would argue that, as the orange portal moved faster, we would also expect to see a blue-shift through it, and from the other side, a red-shift through the blue portal, since the Doppler Effect would be affecting the photons passing through.

The portal is a wormhole, so in essence it removes time and space.
In this instance the cube is not dropped into the portal, but a hole in time and space goes over the cube, meaning it is stationary being transported to another place in spacetime.

It would only fly out if it was dropped into spacetime.

Then prove yourself by showcasing the transfer of energy from the portal to the box. I must make sense and not lol magic.

No, that 10% isn't going to occupy the space where the 90% is, spacetime is moving uniformly, so that 90% is going to be in a different position (relative to the blue portal for instance) when that 10% is then in that position.

B

No, you utter imbecile, the bending of space results in a “hoop”, the “hoop” has no magic powers that make space bend around it.

It not I

Are you dense? What part of portals moving necessitates proving that portals fuck with energy? That's been known since the first trailer dropped in 2007

Alright let's consider the point when it first touches the orange portal as t0, the endpoint when it's all through as t2, and the midpoint as t1.

Now, let's look at the position of any point on the top side of the cube at t1, which has gone through the blue portal, and observe what it does as it moves to its position at t2. That's right - IT FUCKING MOVES. It has to for the rest of the cube to move.

And as the whole cube moves in this way, newton's first law etc. etc. it's fucking b you misbegotten fools

You're telling me that a plank of wood, impacted by a cube emerging from a portal at, lets say 40 MPH, would be gently pushed by the cube?

by this logic the entire world would tear apart once a portal was placed on a moving object. If you consider the space inside the portal to be actually moving then it would have a reaction that would completely fuck up anything in the portals (aka the entire universe)

The cube is not emerging at 40MPH. It's emerging at 0MPH. It APPEARS to be emerging at 40MPH because the portal that is displacing it is moving at that speed, but it is not actually moving at that speed, any more than a train coming at you on TV is actually about to slam through the screen and into your living room.

The portal translates objects through space, it doesn't move them. A moving portal gives the appearance of "speed" because the translation through space is changing over time, but that is, essentially, an optical illusion. The cube is never actually moving.

Does the portal itself transfer force or does it work the same as air when passing through the cube?

What the fuck are you on about? You were the one that said having a stationary box enter a moving portal somehow will allow that box to shoot out by receiving the velocity of the portal. I'm just telling you to prove it by showing the movement of energy from the portal's kinetic energy to the cube's kinetic energy. It should make sense even without going all quantam mechanics.

125 actually

your post literally doesn't prove anything

There is nothing “in the portals”, it’s just a fold in space. The portals are merely the result of the field, they do not control or cause anything.

momentum is relative

Read

>spacetime is moving uniformly
Then spacetime is still acting on the 90% then it should act on the tiny cube before the big cube reaches it. But okay, let's change the scenario to two cubes standing on top of each other, the the second cube will push the first one after portal already displaced the first one, yes? So the first cube gains momentum and goes flying. What if we connect both cubes with a short rope? Then the momentum from the first should pull the the second one, correct?

How can an object pass through a stationary exit without having speed relative to it ?
Oh yeah, it can't.

I think I used the wrong word. It isn't moving. It's warping. It's like moving but you don't move at all.

The cube is actively traveling at 40MPH relative to the plank, though. The topmost point of the cube, relative the surface of the ramp, has gone from point A to point B at a speed of 40mph

oh so it's something you just made up that has no real world implications

The box doesnt move

>Going all quantum mechanics
>In a spacetime that's being fucked by portals
No, quantum mechanics in fucked up metrics is a great way to fall into string theory, which is a rabbit hole you don't want to go into.

The reason why B can happen is purely classical, and comes from the fact that conservation of energy doesn't apply to abnormal spacetimes like, say, one where there is a hole that connect otherwise separate points in space.

You do know warping space is a thing write?

only the part of the object in "contact" with the portal is warping though, the rest has to be moving

The cube wouldnt start flying out even if the portal transferrd kinetic energy.

>thinking force vectors randomly switch directions becaise of shitposting

>portal placed on moving platform
>real world implications

push a hula hoop through a pool and see if water shoots out then retard

No, it hasn't. It's being placed into existence in that space, it isn't being MOVED into it.

Fuck. I meant right.

>Then spacetime is still acting on the 90% then it should act on the tiny cube before the big cube reaches it.
It isn't acting on the cube it's moving 'around' the cube.
>the the second cube will push the first one after portal already displaced the first one, yes?
No, not if neither are moving relative to each other.

This entire fucking shit. It's physics from a video game. There is no correct answer you primates.

Don’t listen to this afag trying to trick you, the hula hoop will break unless you have an inflatable pool, and then your mom will get angry either way.

fug it was supposed to be 200 mph, whatever

don't worry it's just warping, it has no speed

>20 meters per hour
LMAO

>The man is fine because no force is being applied to the sword
That's what I would say, if I were an A-utist.

Alright then oh wise failed Plan B, where do portals come from and how do they work?

It's still close enough to your head that it's gonna be jabbed with a (stationary) sword, one that is obviously mounted pretty sturdily since it's able to stand upright. It doesn't have to be moving 200MPH for that to end badly for you, I promise.

Then show the movement of energy. Explain why it happens that way and make sure it still follow the rule of the universe without breaking any of it. Must be easy because you are advocating for B and thus understand how it happens. Going it just works isn't a reason as real world don't work like that.

can't be jabbed by something with no speed :)

You were trying to be smart but failed like all bfags.
A mass of molecules of metal being brought into existence in the midst of the mass of your brain will kill you just the same.

>it moves relative to something which is stationary
>therefore it never moves
You are so scientifically illiterate that it hurts.

>Show the movement of energy
Total energy is undefined in any system with portals in it, BECAUSE of the portals, regardless of whether they are moving or not. You can make perpetual motion devices in the game without even trying.

portal gun obviously

Black holes aren't portals

I wonder who could be behind this post.

Bfags might be retarded because everyone is arguing about something that is as far away as FTL travel

but Afags are retarded and dead

If you imagine the portal takes 5 whole seconds to pass over the cube, after one second the cube is 1/5th poking out of the second portal, after another second 2/5ths. In that scenario the cube is moving out of the second portal slowly so it has momentum relative to everything else, nothing acts on the cube aside from drag from the air so if it were coming out faster it would shoot out a bit.

What do you think happens when you teleport a dense mass into the space a less dense mass currently occupies?

>it's moving 'around' the cube
If it is just moving around the big cube it wouldn't be able to somehow add momentum to the tiny cube.
>No, not if neither are moving relative to each other.
Well the second cube is moving towards the first one through the portal, as the first cube isn't moving. Just like the big cube was moving towards the little cube through the portal. Are you saying there would be a difference if the moving portal stopped for a second halfway through and then started moving again?

and tell me, what's warping the mass of molecules into my brain? The portal, which is no long in contact with those molecules?

it gently pushes it out of the way? :^)

lmao

>this is the actual state of bfags arguments

1. Relative momentum.
2. momentum can have a negative value.
im not posting a wall of text, with these two facts, you should be able to reach the conclussion that is B.

by b fag logic the bbc should not only just appear, but also shoot towards the right at 60mph. afags and bfags agree that the man will die, but bfags think that the "bbc" will become a fucking rocket

Portals are the effect, not the cause. A portal doesn’t move anything.

Depends on the mass and density of both objects.

But then you are arguing for something that could happen and thus you need to explain your reasoning. Because if not the only reason I got from you is that it happens because the portal can create energy out of nothing.

Why doesn't NASA just use hula hoops to launch rockets?

>A fags think it will come out the other side at 60 mph and then come to a sudden stop, despite no force acting on it to make it stop

>bfags think that the "bbc" will become a fucking rocket
Nah, it stops as soon as the truck slams to a halt, of course.

It will stop, assuming it's attached to the block on the left. or it might possibly break and shoot off.

the long black pipe is still going to go through the portal you dumb bfaggot retard

I wouldn’t call a box falling down an infinite distance a device.

Ok, here you go:

>If it is just moving around the big cube it wouldn't be able to somehow add momentum to the tiny cube.
Yes it would, the cubes are moving relative to each other, even though neither are moving.
>Well the second cube is moving towards the first one through the portal, as the first cube isn't moving.
No, neither are moving relative towards each other, and both are moving relative to the portal.

It's really not that complicated. Just look at and think about it in that fashion.

The truck crashed and thus stop the pole from moving.

The actual correct answer is how the physics engine of the game handles it, and the answer to that is A, because portals are literal teleporters and all they do is translate the object and rotate its defined velocity vector based on the delta rotation between the two portals. Since the Source Engine (like all engines) defines velocity on a per-object basis in world-space and doesn't employ relativity, this is how it works.
