Who would have guessed. But yeah. In the PORTAL UNIVERSE physics do not represent physics as currently theorized in real life. They're a bad aproximation for a video game.

i still don't agree with him. if you use the orange portal as the observation point, it looks like the cube is coming at the portal with a huge speed.

while it would be affected by gravity when exiting the blue one, it would still conserve it's momentum and do a parabolic arc before falling, no?

am i mixing momentum and speed? and most importantly why nobody has done this in-engine?

that's literally how speed works, if you were observing from the portal, then it would look like the cube is coming at you, so it would shoot out from the other one, if they are both in the same reference system

You know, I'm really getting a perspective on why you dropped out of highschool. Your physics class was just too much for you.

>and most importantly why nobody has done this in-engine?
It has been done using the player instead of a cube. The answer is A because of course it's A. The portal is moving, the object is stationary excluding gravity's effect. The object doesn't travel, it simultaniously dematerialises and materialises, there is no movement therefore there can be no momentum.

Do you not have a job? Have you never used e-mail? Gaben forwarded it to someone who is actually relevant to the problem. Since Gaben didnt design the physics for the Portal games.

So he's just one of these talentless developers contaminating Valve.

MODS STICKY

what if everything else moves while the portal is fixed? that would make it shoot from the other one

and the result would be the same, since the 2 scenarios are indistinguibile

That's where you're wrong, bucko. Leave the real world's rules out of it for a moment and think about the video game as if it were a video game. The cube doesn't travel, the game engine just says 'this much of the cube is over here now. Now THIS much of the cube is here and that much is there.' It probably just updates the materialisation status of the object each game tick, no movement happens (outside of gravity).

This has been asked for 15 years.

That answer was retarded, but yes, it was always A. As the cube itself is not moving, there is no fucking momentum to "preserve."

Didn't another developer place his bet on B in a mail?

Based.

A hula hoop isn't a portal dumbass. The space on each end of the portal are unified. If you were watching from the output side you couldn't tell if the block was moving towards you, or the portal was moving towards the block. If the block was being propelled then you agree then it would go flying, but from the outsider's perspective the two possibilities are identical. You have to at least admit B as an equal contender.

why was this deleted?

That's literally irrelevant, the guy is clearly giving his opinion on what would happen in the portal game universe, and not the real world, the point of this retarded image is to guess what would happen in the real world, the portal references are there just to help you conect the dots on what's going on.

Also more importantly i believe the reason he chose a is because the box on b does not look like it's falling down as a result of gravity, and while that is technically an issue (not really, the cube could just be going really fast), it's not the point of the thought experiment, it's about the momentum of the box when going trough the portal, and lastly if you actually care about his opinion for some reason he clearly said the object's momentum is conserved, so b is the corect option both in-game and irl

Your issue is that you're basing your conclusion on your retarded assumptions.

Ok look at it this way. The wall hole is a portal that leads to a road. At the end of the road is a target. The wall is roaring towards you at 200mph. Before you jump you can see the target moving TOWARDS you at 200 mph. You somehow make the jump. Why would your velocity relative to the target suddenly change? You WOULD get flung out of the portal!

Wrong. Momentum is preserved. Therefore 20 m/s in, 20 m/s out. The "speed of the portal" is irrelevant. It only affects the rate at which the object enters the portal. Go be gay somewhere else

I'm not debating that, but the other half you're omitting makes it sound like that statement has little to do with what everyone is arguing over in these threads.

>Man goes through the wall without moving
>The only reason anyone on that show does move is because they are propelling themselves or the wall pushes them back
WHERE IS YOUR GOD NOW ATHEIST? s

The obvious answer is C.

Yes because it’s not the same kind of portal. Momentum is conserved because it just spits out anything it deconstructed at the same speed it went in regardless of if it was it or the gate moving.

>Something that is literally shown in an image is a retarded assumption
How is the cube on top of the portal if it didn't move through? Did it just instantly teleport?

No, faggot. I'm basing my conclusions on basic fucking logic. Divide the box into 10 equal segments from top to bottom. Section one will pass through the portal moving at the speed of the orange portal. Section 2 passes through at the same speed and simultaneously counteracts any drag experienced by section 1 by pushing it at an equal amount to the drag (basically, if section 1 was slowed it would be forced back to the portal speed by the following section.) This all results in the final section leaving the portal at the speed of the orange portal as well, meaning the entire cube is now moving out of the blue portal at the original speed of the orange portal, and will therefore have momentum relative to its speed and weight. The reason this problem makes no physical sense is just that; portals defy the laws of physics in the first place.

No he only gets flung when the orange portal stops. The change in momentum of the orange portal is transferred to the man.

Some people are retarded

if you drop a hula hoop over a cube, the cube's not going to suddenly accelerate out the top end. a portal's just a hula hoop where the top end goes to a different location. the force of gravity changes, but that's it, which is why the cube plops.
relative to the hula hoop itself, the cube does appear to be accelerating at approximately 9.8m/s/s (slight variance due to friction and possibly relativity), because that's the speed the hula hoop is accelerating toward the ground. but the force vectors in b are all wrong and don't match what the hula hoop would be seeing.

Use the blue portal as a frame of reference. The train enters at 10 m/s, so it leaves at 10 m/s. If the train left at 20 m/s, that means it would exist in two places at once.
Once the front part of the train exits the orange portal, it will gain speed due to the torque of the wheels, eventually bringing the front part to 20 m/s and the back part to 30 m/s.
Assuming, of course, the train's motion comes from its wheels and it's not moving on a frictionless surface.

If enough of it is through the portal it will probably get pulled down due to gravity because the heavier side is now hanging in the air.

No one ever asked about what would happen in the portal universe, people tested it we knew all along that A was right for the Game. The whole discussion was what would happen in our world and that's "more likely B, but can't be proven".

>redditor uses reddit image to defend reddit argument

The answer is: there would be a train wreck.
Assuming the source of force of the train is to the front, when the train exits the portal, the front will try to continue its velocity by pulling on the track at 20ms-1, which will either have enough strength to pull the rest of the train and acellerate, or be pulled back and deccellerate. Either way, after exiting the portal, the train will have alot of strain between the area where it crosses the portal. So itll either not break thus equalizing the relative velocity of the 2 train parts to the portals, or completely break off due to the sudden strain applied to one small part of the train.

It will exit at 20, but the back end will seeming be forced to speed up to 30 to compensate according to the way we know it works in game

>Not even reading my post
Actually use your brain and read that again user

See

>what happens if the orange portal platform stops halfway down the cube?
a portal is just a hole
since it is just a hole, the only difference between one side and the other is the force of gravity
the cube would be pulled by gravity in two directions. let's arbitrarily say they're directions 9 and 5 on a clock. if you pull an object in those directions with the same amount of force as gravity, it's going to move a bit until something balances out. nothing super interesting will happen.

The cube doesn't go through the portal at all in game since it wasn't coded to be able to do so. The in game answer is that the cube gets crushed, which is just as reasonable as A or B.

>If the wall was moving faster they would definitely propelled through!
REAL LIFE PROVING YOU NIGGAS WRONG

A. The cube is stationary, meaning it will have no momentum the moment the portal connects with it, causing it to gently plop out the other portal.

You have to be really bad at physics to not understand this.

How the fuck would it pass through slower user? Implode on itself? There's physically no space for the next section to occupy if it exits slower than the speed of the orange portal.

Attached: 1554197700402.png (261x330, 33K)

Say a portal is moving at like 2000 mph on a platform moving horizontally, like a deadly fly swatter coming at you. You jump up from a standing position, being "swatted" by this giant fly swatter with a portal attached.

Somewhere else the other portal is on a wall, stationary.

Say the moment you're swatted you have ZERO momentum. You're at the climax of your jump.

By conservation of momentum, you exit the second portal with no momentum, right?

Right. You had no momentum going in, you have none coming out.

What the fuck made you exit the other portal though? You're not moving, so as the first few inches of your body goes into the fly swatter portal, it's "motionless" in the new portal because you're not continuing to leave the second portal with any movement.

So the fly swatter, as it moves, is smushing your body into the one from the other side.

Basically- as you enter the fly swatter, WHAT on earth is pulling you further into the "room" coming from the 2nd portal?

I know it's bait, but yes, Newton's model is incomplete. It wouldn't be able to deal with Portals which is where GR comes in to solve the issue.

the cube has momentum relative to the orange portal

Programmers aren't physicists. Programmers and engineers don't know anything about physics besides freshman year crap. Even implementing physics in a game doesn't mean you know that much about physics.

There are no absolute reference frames. The cube is moving relative to the piston. Thus the cube has momentum. If momentum is conserved through portals then B is the only possible outcome or else that momentum would be lost instantaneously which makes absolutely no sense.

Shut the fuck up about physics Yea Forums. You don't know anything. Taking calc-based physics 101 for your le epic cs/engineering degree and thinking you know anything is laughable.

people assume the portal's movement has volatility transfered to the cube, but clearly a moving hole has no mass. hah! I see now. I am a B fag no more.

well, speaking in in-game terms, nothing happens actually, there is a test map that proves it

>it wouldn't be able to deal with Portals
Ah yes, that is why objects that go through portals conserve momentum. Can you imagine you're so retarded that you don't understand how baby's first platformer works? This is your brain on Yea Forums!

Attached: laughing gundams.jpg (630x472, 59K)

It doesnt work that way, because the portals dont fucking teleport stuff, you massive idiot. It creates a pathway between the two places. Thats why you can have objects that connect inbetween the portal at once. Your cube doesnt magically gets cut off in half when you put half in and pull out.

>Taking calc-based physics 101 for your le epic cs/engineering degree
You're giving Yea Forums way too much credit.

What, on the other hand, is reducing your velocity relative to the stuff opposite the wall? You are seeing it come towards you at 2000 mph, and suddenly it stops? Neither is more correct, because portals can't exist.

if the back of the room was an empty space as it is in the portal explanation I would remain unmoved as I was never moving in the first place just the room

It's not stationary, retard. It has momentum relative to the piston. That's all that matters.

Except one half the hula hoop is a different inertial frame, which makes no sense

unless if the portal edges interacted with the cube would the cube budge. but absolutely spot on.

So now that A-utists are claiming that the game's physics is the only decider on the issue, can we also start claiming that all bugs and glitches that occur in Portal must also happen in real life?

You repeated this stupid shit few times already.
Universe doesn't enter the portal, brainlet.

And how can you tell the difference between being stationary and having a constant velocity in empty space? If there was air then it would feel (and be) the same if you or everything else was moving. This is literally the basics of relativity. Read a book.

no matter how hard you drop a hole around an object, the object is not going to accelerate out the other end. if the hole keeps moving, the object will continue to "accelerate" relative to the hole just as it was before, if the hole suddenly decelerates (e.g. stops), the cube will suddenly decelerate as well.
while it might be interesting to ask what would happen if the orange end of the portal in the op pic was allowed to keep accelerating after it enclosed the cube, it doesn't, it comes to an abrupt stop, and the other end was stopped all along. the cube will "decelerate" relative to the portal as both ends are stopped upon exit.

>if the hole suddenly decelerates (e.g. stops), the cube will suddenly decelerate as well.

BUT THE BLUE PORTAL ISN'T DECELERATING

i think i remember the argument now. or at least part of it.
basically what said.

>from the perspective of the blue portal, the cube is coming out at a certain velocity.
>you can say that in truth it is the orange portal that is moving, but from the viewpoint of the blue portal, the cube itself is clearly moving while it's coming out.
>you can say that the portal is just a hole, but that's is just a random assumption.
>because you can also say that the portal is disintegrating the cube and creating it on the other side. and in that case the cube would have a real momentum when leaving the blue portal.
that's why i said, the answer depends on how the portal actually works, and portals aren't real. of course in-game the answer is A.

Hole in the wall has the same speed on both sides: it acts as a standard hole.
The problem is what happens if there was a hole in the wall but one wall is moving and one is stopped and the hole is a portal, you retarded monkey.

OH NO NO NO

just start arguing in your first language dude

So what happens.

No, the problem is that one side of the hole is at a different frame than the other, which is impossible with a real hole
Please learn how to read

that's also why i brought up the space example.
it kinda shows how absurd it is for the cube to come out at X-speed but stop moving once it fully came out.

relative to the cube, the blue end of the portal was never moving. relative to each other, the blue end of the portal and the cube are both at rest. the orange end is the only end that could maybe have something interesting going on (and that's a stretch), but it comes to a rest as it hits the cube.
as all forces at the time of entry are at rest with respect to each other other than gravity, gravity is the only force at work, and gravity is a pretty weak force. the cube originally is accelerating at the speed of gravity downward (and is repulsed by the force of the platform it rests on, zeroing out), and at time of entry, the force of gravity changes its vector to another position, which the cube follows and "plops"

>Perspective of the blue portal
So why does OUR perspective no longer exist?

but he is propelled forward if you use the wall as the reference frame

it's basic physics, not even GR
en.wikipedia.org/wiki/Frame_of_reference

Now that I look at the explanation, I think the dev might have misunderstood the pic and assumed that the platform below the cube is moving, not the one with the orange portal.
He says that the object's momentum is conserved across transition, not that it gains momentum from the transition.

>All B-fags have a PhD in Physics and have taken actual advanced Physics courses and thought the only answer that made sense was B

What does this tell us?
I'm sure there's an explanation for all of this...

About fucking time

Let me put all of you in a better perspective.
Let's instead put Orange portal as the point of reference, which means that the cube and blue portal are now moving and orange portal is stationary. This means, that when the sube passes through, it would be moving relative to the orange portal, but will be moving at the same speed/velocity as the blue portal. This means, that the cube will not be moving away or any different than the blue portal, therefor it has to be A.

Or the point of reference can be blue portal, and after orange portal has passed through, the cube would be not moving relative to the blue portal, thus will not fly away.

Both are still moving relative to the orange portal, but not to each other.

a door is not meaningfully different from a portal for this example, that's the whole point retard.

How the fuck could you pick B
For all intents and purposes the orange portal is literally just a hole, the fact that platform it is on is moving is absolutely irrelevant.

post more my fellow spic.

the more retarded shit you say, the more people will point it out and the more you will learn

Afags believe that you can have a hole of constant thickness where one side is moving at a different speed than the other

The stationary object doesn't give a shit if one side of the hole is moving or not. If that hole int he wall suddenly sped up when you were halfway through you would not propel out the other end because no forces acted on you.
>B-but the portal thinks he's moving therefore he will be flying forward from our perspective too
I feel my IQ lowering just talking to you later homos.

I see not many people understand physics to have the need to ask that question.

Relative to the blue end of the portal, the cube that is emerging from it is not still. It is moving, hence it is emerging from the portal.

You havn't heard of the special relativity defense? Its a legal loophole that works every time. That's why they never got Einstein for a single parking ticket.

What about portal 2 ending?

if you drop a hula hoop around a weight, the weight is accelerating toward the hula hoop at approximately the speed of gravity
if the hula hoop is allowed to continue downward after it passes the weight, the weight will accelerate away from (upwards) the hula hoop at the speed of gravity
if the hula hoop is obstructed after it reaches the weight (the weight is on the ground), the weight will suddenly stop accelerating relative to the hoop (because the hoop itself decelerates relative to the ground)

I have a PhD in image board culture and I can tell that the Bfags claiming to be astrophysicists are in a 78% likelihood full of shit.

his half will move with the portal while the other is stationary, it's not that hard

It is different, and I've already explained why. Unless you have a counterargument please stop.

assuming both portals are in the same room and the only thing that's moving originally is the piston, the blue end of the portal and the cube are at the same relative velocity (0)
the orange one is moving, but it stops when it smacks into the platform the cube is on

Portals act like doorways, nothing more.

How do you not get this? The portal ceases to be a simple hole in the wall as soon as one end has a different inertial frame. Using the hole in the wall argument is not a defense.

If anything he will fall forward, it's like having one foot in a car and one on the ground

I wonder why they decided to go for the simpler, "makes sense" physics model instead of the harder to grasp, real world model.

interesting question. That would mean that if the portal does not have any space inbetween them, it would mean that either you will be squished into literally nothingness, or your cells' elasticity will push each other out of the portal, and you'll probably be hurting like hell when you exit.

Yes the point is that portals break special relativity. That's all little ol' Bfag me is trying to get at. The Afags who act like their solution is bulletproof physics-wise are wrong.

user pls
i haven't so much as held a calculator since my high school graduation but even i undestrand it doesn't work that way

Because as the cube enters the new room, the red portal is forcing more of the cube to exit out into the blue room.
Think about it- an inch enters the blue room with zero momentum. It is "staying put" in the blue room. But more of the cube is fed through, and it pushes the previous inch further out.
What determines with how much force that first inch is pushed out?

This all has to do with the relative velocities of each portal. This isn't simple, and has more to do with the exact mechanics of forces acting on objects existing between portals.
Like such:

>m-m-muh huler hoop!

Is there a greater sign of autism?

Wrong. The end of the cube that emerges from the blue portal has a positive velocity relative to the blue portal while it is emerging from the blue portal. Otherwise it would not be able to emerge. The question is, why would this velocity (which again HAS TO BE GREATER THAN 0) suddenly change to 0 when the cube is all the way through?

I didn't play it, but seen mentions about it, just asking.

>If that hole int he wall suddenly sped up when you were halfway through you would not propel out the other end because no forces acted on you.
if you place a camera on the wall, and speed up the wall, it will look like the guy is speeding up halfway through

Does Gaben actually read mail from plebs? Damn

Can we all agree that the intuitive result is different depending on your reference frame, and that therefore there is no physically correct result?

user, the most intelligent scientist doesn't use calculator. They operate in the abstract. You not using a calculator is not a good indicator of you being retard.

if his foot isnt touching the ground or affected by any resistance/friction from the air, his blue half will literally be stretched out, and he wont be affected at all.
If he is affected, he'll either trip forwards throught the blue portal, or be pushed back by the air rushing through.

I think we're just getting started.

It is just a fucking hole. No the universe doesn't move with it. If it does, the other side of the hole would also be affected. For all intents and purposes, any object on the other side of the hole will follow the logic of that side until they are on the other side.

autism is not letting go when you are presented with a satisfactory conclusion

This is the correct answer- or rather theory of mind.
We're to look into the behaviour of the "fine line" between 2 relative spaces acting at different velocities.
As in such:

S T I C K Y
T
I
C
K
Y

when?

All those perspectives are equally valid, and have to produce the same result, is the thing. If you look at it as a stationary cube and moving portal, the portal is transferring its momentum and kinetic energy to the cube. If you look at it from the portal's perspective, the cube is moving in (and also exiting) at a given speed. The platform is the same as the cube, except it never goes through the portal so it doesn't really tell you anything. The world's perspective? The planet is seeing the same thing as the room, which is a portal (with a whole universe inside it) rocketing toward a box. If you mean the universe's perspective, there isn't one. There are no absolute reference frames, which means portals don't make any sense in the first place.

please continue humiliating yourself

It's not a hole. A hole cannot have two speeds simultaneously. Please think before posting.

>the cube would be not moving relative to the blue portal

But why would it not? It's been moving through the entire process of emerging from the blue portal, so why would it stop moving before going through its full trajectory?

/int/ doesnt apply anymore. That place is now 50% a shit pol and the other 50 are flatfags and/or trolls

I always said it was A because of the hula hoop argument. Glad we can finally put this to rest and B fags can rest easy knowing they were forever wrong.

i don't know, maybe report it so the mods take notice

Both A and B outcomes are possible.
The real frame of reference is the exit portal and your speed relative to it decides whether you get launched out of it or just "plop" to the ground.

Cope

A fags think that if there are more reference frames in their favor that they are right like it's some kind of vote.

The portal is not a teleporting device that ejects objects out of itself. Its a doorway that connects 2 places in space, therefore it is literally moving through the portal like through a door way, and not ejected when it travels through.
I hate to use the door example, but its the best one.
Imagine you running through a door. Youre now moving relative to the door, and go through using your momentum
Now imagine the door faling on you. The door is now moving relative to you, so you get through the door without momentum on your part. Or you could look it as the door is stationary and you+the ground is moving towards the door. When it passes through, the ground and you will still be moving relative to the door, but both will still be moving at the same speed/velocity to each other, so you don't suddenly fly away from the ground.

there is no real frame of reference, but is right. looks like everyone forgets that the cube and the blue portal are both not moving, so even if you consider the orange portal as the reference frame, then not only the cube will have momentum, but also the blue portal, making it A in any case

You haven't explained shit, because you're still thinking like a caveman that portals or teleportation functions as "really really quick movement" instead of actual teleportation.

That'd be weird. The guy would technically stay in the same position as the platform is moving, but he'd be feeling the wind blowing in from his left side, not to mention a lot of friction with his left foot. I imagine he'd eventually tumble out of the orange side dizzy. It'd be hard to stay stationary in that situation.

In that case both portals are moving. In the question at hand, only one portal is moving (or, the displacement between the portals (ends of the door) is not time-constant). That makes all the difference.

The other stationary platform dingus

why did it take so long?

Both A and B are wrong the cube would not fly or plop. It would gently slide down the slope.

In this case it's actually like talking to god and asking him how it works, considering the guy made the physics in that game and that the world only exists and functions because of his rules.
