>Doesn't show the box going through it
Nice try, faggot.
An imperfect simulation of a thought experiment provides imperfect results in situations not planner for by the simulation devs
Portals cannot be set on a movie surface. This used console command cheats to work.
It's invalid
People defending A are basically defending that the portals are hulahoops so I doubt anybody thinking it's A think hulahoopers are retarded.
Last nights thread had hooptards ridiculed by both A, B and "lol portals don't exist" fags
You know I'd say portals can't move but then they are on earth which is constantly moving around in circles And around the sun.
STOP MAKING THIS FUCKING THREAD
>when people say stupid shit regarding real facts
When you go anywhere do you factor in the thousands of miles per hour you're always naturally going?
All I'm saying is if portals are on earth then they are technically always moving. There wasn't any deeper conclusion than that. Though I suppose it would make trips through portals that are really far apart pretty dangerous. Like really far though.
If A people were shitting on hulatards then they are more retarded than we ever imagined.
I literally don't get how people don't realize it's A. The box itself has no acceleration, only the one of the portals.
Imagine an open door coming at you at a rapid speed and stopping just as it passes you. Do you magically shoot out the other? No, you'll just keep standing there
according to lore it can be on a moving surface
it happens in the game
> hoopfags again
>just ignore the whole space bending wormhole thing guys it’s just a hoop
Retards don't realize that the Box itself has no speed to launch through the Portal. If you jump through a portal located beneath you then of course you'd get launched out the other one because you yourself are in motion while falling. If you don't move and a portal comes from above, you wouldn't get launched out the other one. Where would you get the speed for that from?
The magical doorway that's thrusting the entire universe at you.
You already have it in the frame of reference of the "other room" on the other side
Think about it the other way around, imagine stepping through a portal into one that's in a speeding car. Would you suddenly fly through the back window because you're "stationary"?
It's just like going through a door. If the door moves but you don't and the door stops moving after it's behind you you don't magically get forward motion and get thrown against the other wall of the room. You just stand there. You'd have to jump through the door into the other room to get said forward motion.
>H-h-h-hoopfaaaaAAAaaag
Honestly this.
If you mounted a speed sensor on the doorframe as it moved past you, the sensor would register you having a nonzero speed as you moved past it. Because from the door's frame of reference, you are the one moving and it is the object staying still. This is the most basic of all concepts of relative motion. They teach it in primary school. In the case of the portal, the portal preserves the momentum of the object entering as it exits. In essence, were we to mount speed sensors on the entry/exit halves of the portal, the sensor readings as you come in and out would match. When the portal is standing still this means that if you run into it, you come out of it moving fast. However if the portal itself moves, the entry speed sensor would register you having a nonzero speed as you enter it, even if you were standing still. Again, relative motion. Primary school. And the exit portal would dutifully replicate this momentum as you come out of it.
The answer is B. A child could tell you this.
The difference is that as soon as you pass the threshold of that "universe", all the momentum is gone. meanwhile, if an object is travelling through a portal it maintains that momentum and goes farther.
The answer is A.
Everything you said only supported A.
You don't magically get forward motion, you don't feel any change, but you're deposited into a universe that's rapidly moving past you. Imagine teleporting onto a plane, you wouldn't suddenly feel a push, but you would be moving at the speed of the plane.
how long will these threads continue?
They have been going for years, and will continue for many more.
>Yea Forums tards think an object that is at rest will move despite there being no outside forces applied to it
Until Portal 3 releases with moving Portals. So never
What is even being discussed? The theoretical scenario as it would happen in game, or the theoretical scenario as it would happen in real life?
Maybe if you're a retarded brainlet.
>MUH MOVING DOORFRAME YOU WOULDN'T COME FLYING OUT
>except the doorframe would indeed "see" you as moving
>BUT THAT DOESN'T COUNT YOU WOULDN'T COME FLYING OUT OF THE PORTAL

retard
Hoopfags, doorfags, and anyone else who thinks it's A clearly never passed high school physics.
When I kill the one true omnipotent god of our multiverse and usurp its throne, this never ending debate is the first thing I'm eliminating from existence
Thank you.
30m/s, assuming the orange portal is stationary.
Both
This is literally freshman high school physics
>what is the relative speed between the blue portal and the train?
>that is the train's speed when exiting the orange portal
10m/s
it's the train tracks that are moving at 10m/s
Redpilled.
Bruh calm down lmao
B
unless you are a retard and dont understand relative momentum and that objects can attain negative momentum, ir relation to stationary environments.
you know its not a question just because you put question marks
I know it's not a question just because I put question marks but did you know that I already knew that?
doesn't seem like a likely story
To answer your implicit question, both halves will probably remain stationary relative to their portals.
It's a joke picture mocking this topic.
>Yea Forums doesn't know basic physics and tries to apply impossible scenarios with cake meme portals
Still better than retarded smash thread.
but that's a flawed question, portals can't and couldn't move
you can move through space time, but you can't move it
B tards belong in the garbage.
y'all are some unmedicated autismobutts
The fact that the train is moving is irrelevant because both portals and the gun all share the train's frame of reference. They're all stationary with respect to each other. The only relevant factor is the 100 kmh firing speed of the projectile. The answer is B.
B, the fact the train is moving doesn't matter because its being shot from an objected stationed within the train itself. In fact this example only supports A on the original one.
Wait, so why don't you come out flying when a hoop is thrown over you? From the perspective of the hoop, you are moving and thus have momentum, where does it all go?
I'd say it's neither, because the train is moving, aka both portals are moving, meaning the cube would indeed go through the yellow portal, get through the blue portal, but then instantly go back through the blue portal due to them moving (and the cube keeping its neutral acceleration)
Where would it go? The hoop observes you having X momentum coming into the hoop, and X momentum coming out of the hoop. No forces acted on you to change your apparent momentum.
thank you for providing my evening with entertainment
That's not how relative motion works.
mythbusters did this
youtube.com
but that's the thing, the cube is literally not moving, it shot at the same speed as the train; aka his acceleration is 0m/s
and it wouldn't gain any acceleration simply due to the portal he goes through having some
>The orange portal doenst cover the edges and corners of the table where the cube rest
>The slam between the press and the table produce enough PSi to launch the cube with speed
The answer is B
If you think the answer is A, you have to explain why the train in gets crushed because it's only coming out of the exit at 20m/s.
>it shot at the same speed as the train; aka his acceleration is 0m/s
This is true for an observer standing outside the train. The portals are not outside the train. They move with the train. From the perspective of the portals, which are moving with the train, the cube has a speed of 100 kmh, moving left.
Thanks for fixing up this guys smooth brain user.
In layman's terms, speedy thing go in, speedy thing come out. The box has no velocity. it would just drop out the front.
speedything tards are always tougher nuts. The explanation to why it's actually speedy thing requires 3 braincells
IF a portal flew at you a person, and you hopped as you passed through it, would you stumble when your feet hit the ground or would you land as if you weren't moving at all? Big brains will know you don't move since you had no real motion and world moved around you instead. Meaning A is the only choices
But then, noone really thinks B is the right answer and this trolling will go on forever
we've been literally been discussing this on this board for more than a decade
Initially 30 m/s
Drops back to 20 m/s once the blue portal is no longer in contact with the train
to be honest nothing says that portals don't behave like a cylinder would and in some way it makes sense that one portal would be affected by the same energy that moves the other so that kind of makes both A and B answer potentially correct
also B is obviously the right answer you newfags
Neither. It just sits there
>Drops back to 20 m/s once the blue portal is no longer in contact with the train
Instantly?
If a portal flew at me I wouldn't be in this version of reality and I can't make any meaningful prediction on what would happen in such a universe.
>If you mounted a speed sensor on the doorframe as it moved past you, the sensor would register you having a nonzero speed as you moved past it
That's wrong. It would detect speed. Do you people even know how a speed-o-meter works? lmao
well how can you be sure the portals exist if you can't prove reality is real?
> this example only supports A on the original one
But then
The box is not moving as the orange portal swallows it.
Then the box is moving as it exits the blue portal, and it moves at an even greater speed than any of the portals.
How does an Afag explain the momentum gain? I thought they believed in conservation of momentum.
The fact that there is a train moving around the experiment doesn't matter. It's just a bunch of steel or woor or whatever moving along.
>jump on to a moving treadmill
>slam face first into the ground
>wtf I had no real motion the treadmill moved underneath me instead
this is equivalent to this
I'm sorry you're retarded user, thinking the ground will be moving under your feet if a portal passed around you
Literally the only thing you need to understand why b is right
lol that's some top tier bait
Whoever made this webm should add a ball or some other obviously non-stable object on top of the box for greater hilarity.
it's not possible for B to be right because then it would mean the cube would get disintegrated by the fact that its atoms would suddenly start accelerating but not at the same time
the same way you wouldn't just be swallowed by a black hole, but your extremities (whichever points towards the blackhole) would be swallowed much faster and sooner than the rest of your body
how so?
that's what would happen
basically what i posted
why is the box glued to the platform?
SPEEDY THING GOES IN
SPEEDY THING COMES OUT
The box is NOT the speedy thing, that is the portal. How hard is this to grasp?
Imagine you've got a portal on your wall, looking into another room. Now move the entry portal to a different wall, you have the exact same view into the other room, even though your entry portal has moved. It's as if the other room has jumped places. Now imagine moving the entry portal gradually towards you. The other room would also appear to be moving towards you.
box exerts force onto platform, platform pushes back thus equilibrium
A-fags believe they would be able to stand on that platform after going through blue and should be banned
idk, why did you glue it?
but yeah I guess the box would leave the platform, but because of the platform and not because of the portal
if the box (somehow) was suspended in the void then this is exactly what would happen
from the frame or reference of the purple portal the cube is speedy
Would you volunteer to stand on the platform as it shakes?
because i can't into animating shit that well, but i found this somewhere
Yes and it would stop the second a piece of you went into the portal. It would be as if your reality blinked out and you appeared in an alternate universe. Like a mage's blink, the only force that acts on you is gravity in your new teleported position.
because when the pedestal leaves the portal you can completely erase portals out of equation, at t his point it could have just as well been a normal extending arm
Somebody answer me this:
It seems clear that if the platform underneath the cube were moving upwards, towards a portal, the cube would fly out the other end. After all, it's being pushed upwards, and that energy must go somewhere.
What, from the portal's point of view, is the difference between this scenario and the one in OP? The portal shouldn't be able to "tell" the difference, right? It is flying into the portal with the same amount of speed.
you can't explain that to atards because you need to have even the basic understanding of relativity which they lack
>it's not possible for B to be right because then it would mean the cube would get disintegrated by the fact that its atoms would suddenly start accelerating but not at the same time
Whoa dude you've pointed out one of the reasons why portals wouldn't work irl, good job. By the way the exact same phenomena (instant disintegration) would happen in-game whenever you put the blue portal on the floor and the orange portal on a wall, and jumped in, due to the instant change in direction (vertical to horizontal) of your motion and thus the literally infinite acceleration produced. Don't worry about it.
It has acceleration in portal's frame of refrence.

>INSERT PREVIOUS ARGUMENT IN A WHINY MANNER
Why the fuck do you people argue like this.
The entire argument is based around what point of view you're looking from. If you're looking from the box's point of view, then it has no momentum and thus shouldn't move even if a portal slammed into it. From the portal point of view, it's like you said. Personally, the game (or Glados) says that portals CONSERVE momentum instead of modifying momentum. If portals did have an effect on your momentum, than wouldn't a portal on a still surface slow you down as you moved through it?
Okay, let's imagine that portals connect not two places in same universe, but connect two identical universes that 69'ing each other through portals. What now?
YES
so I'm right
neither those things would happen
Based on the way portals are stated to work in-game it is B. If that breaks irl physics, so be it. It's B.
I seriously don't understand how relativity works.
Let's say I fire a bullet into a wall.On top of the bullet there is a microbe.
From the microbe's perspective, everything around it is moving at the speed of bullet, just in the opposite direction, right? So when the bullet hits the wall, what exactly justifies everything around the bullet not budging an inch? Where does all the momentum of everything aroun the bullet go?
Please don't make fun of me I never took Physics.
Somebody post the "I am the author" comic
You’d fly through the back window because the car is moving and you aren’t,
>Personally, the game (or Glados) says that portals CONSERVE momentum instead of modifying momentum. If portals did have an effect on your momentum, than wouldn't a portal on a still surface slow you down as you moved through it?
No. If the portal is still and you are moving, the portal registers your momentum and transfers it to the exit portal. Speedy thing comes in, speedy thing comes out. If the portal is moving and you are stationary, the portal registers your apparent momentum and transfers it to the exit portal. Speedy thing comes in, speedy thing comes out. The portal can't telepathically know your momentum from the point of view of an external stationary observer. It can only measure things from it's own point of view.
why is there never any option C? The cube wouldn't just slide out and it wouldn't shoot out like a rocket. It would make a small arc due to the space between the wall and the portal closing and causing friction
>wojak gets in the hoop at X km/h (portal is the frame of reference)
>wojak gets out the hoop at X km/h (portal is the frame of reference)
>it does spontaneously accelerate too (if the camera guy is the frame of reference)
Pretty much it
Your frame of reference must not be an accelerating one for basic relativity to work
>when you move fast in car and look outside the window the trees move fast as well
>when you stop, nothing moved
>how come :?
Personally, I think it's pretty clear the cube would stand up and do a little bow.
Draw it...,?
>I seriously don't understand how relativity works.
Simple example:
You are in the backseat of a car on the freeway, that is moving at 100 kmh. You are holding a ball. Both yourself and your ball are strapped into the car, you are all moving at the same speed. You toss the ball into the air. The ball is still moving horizontally at 100 kmh, same as you are. However, do you witness it spontaneously go flying into the windshield? No. Because RELATIVE TO YOU, the ball is stationary with respect to horizontal motion.
Another example:
You are again in the car, moving 100 kmh. A car ahead of you in the same lane is also moving at 100 kmh. Do you witness the car flying away into the horizon? No. The car looks stationary as you keep pace with it. Because RELATIVE TO YOU, the car is stationary. Next, a car on the other side of the freeway moves past you going 100 kmh. However, the car looks like it's going as quick as an airplane; it shoots right past. Because RELATIVE TO YOU, the car is going 200 kmh in the opposite direction as you.
Object dosen't move. Entire universe moves instead.
So you stick your head through, you're now totally still in the exit room, but your body is moving with the moving entry portal?
The portal is approaching the cube at 20mph, or the cube is approaching the portal at 20mph. If the portal DIDN'T suddenly stop after engulfing the cube, the cube would continue moving through the portal at 20mph like in answer B. But since the portal DOES stop moving after engulfing the cube, the cube will not continue moving at 20mph after the portal stops behind it.
Basically, the cube will move through the portal at 20mph until the portal stops behind it, in which it will immediately descelerate WITH the portal to 0mph. Thus the answer is A.
>enter a car
>crash it into a house
>tell the police that you were standing still and it was actually the house that crashed into you at 100 mph
That's Bfag Relativity 101 for you
How come?
You caused it to crash into you at 100mph tho
Well I mean in this example you're standing upright and the portal is coming at you face first.It'd be as if walked through a doorway, literally. the ground would morph beneath your feet. If you stuck your head through your body wouldn't move an inch, if portals were invisible, it'd look like your body was popping into appearance out of nothing
>Personally, the game (or Glados) says that portals CONSERVE momentum instead of modifying momentum.
Portals do conserve momentum relative to the portals themselves, but they do not conserve momentum relative to the exterior environment, since they can change the trajectory of the object as an integral game mechanic.
Most A-fags would [correctly] say B in this example but they fail to realice what it implies to their theory of conservation of momentum since the box is static at 0km/h as the orange portal shallows it but then it is catapulted from blue.
How does the cube remember it's not supposed to be moving if it's within a room carrying 20 niggers of momentum?
From the perspective of the microbe, an enormous wall is flying towards it. It and the bullet inevitably gets crushed by the wall, and the wall continues zooming backwards, carrying the crushed bullet and microbe with it. Just like a fly hitting the front of a train.
The cube would fall to the ground when shot out of the cannon, it wouldn't even reach the portal.
The momentum is in the ENTIRE UNIVERSE behind the portal. That momentum immediately stops as it engulfs the cube and the relativity between the cube and the ENTIRE UNIVERSE behind the portal becomes 0mph.
what woulkd happen if I punched the edge of a portal? whould my hand get cunt in half since portals are 1atom thin?
How does your body not move? Your head is sticking out of a portal that's stationary, but the rest of your body is hanging out of a portal that's moving through a room.
moving portals create this difficult shit: the cube (and the whole universe) is moving and not moving at the same time
But the cube is already in the room. Why would it stop?
Because portals conserve whatever momentum you had. IF you're standing still, you just pop into existence in the new spot in the universe that's all. If'd look as if you're materializing like some startrek shit
So what happens when observer B observes himself through the portal?
tries to fuck himself
But you don't just pop through, in the game you can waggle objects back and forth half way through the portal. The whole problem is what happens in the in-between stage.
Because the universe "stops" to match the momentum of the cube you niggy.
Another way to think about it is if you jump through stationary portals but the universe on the other side suddenly moves AWAY from you at the same speed as you're moving through the portal, your momentum is immediately nulled.
Y'all conservation of momentum dudes need to read this en.wikipedia.org
>Momentum is a measurable quantity, and the measurement depends on the motion of the observer. For example: if an apple is sitting in a glass elevator that is descending, an outside observer, looking into the elevator, sees the apple moving, so, to that observer, the apple has a non-zero momentum. To someone inside the elevator, the apple does not move, so, it has zero momentum.
All it is is teleportation magic man, don't think too hard about it. Our rules of physics don't apply to the actual in between, it only applies on the parts in the universes
>I seriously don't understand how relativity works.
A quick conceptual rundown on Einstein's special relativity:
Special relativity begins with a basic assumption that isn't relativistic in the slightest: "the laws of physics are the same in all frames of reference." Which should make sense -- it's the assumption that there exists only a single ruleset to the universe which applies equally to everyone, everywhere.
This has a hidden catch, however: it breaks how we understand the motion of light. Specifically, it imposes the condition that "the apparent speed of light is the same in all frames of reference." Why is this? Because the speed of light is decided entirely by two physical parameters of the universe known as the electric and magnetic permeativities in a vacuum. Right now it's not important to know exactly what these govern, but they are fundamental physical laws, in the same sense that the electric charge of a proton is a fundamental physical law. And by Einstien's central assumption, they must be the same for all observers and thus the speed of light is invariant for all observers.
This BREAKS our understanding of motion. If you're in a car on the road, and there were two people in cars moving with and against you, and people in these cars shone flashlights in your eyes, the apparent speed of light coming from both flashlights would be EQUAL. But because one car moves with and the other against you, we would expect one light ray to be moving twice as fast as the other. But this is not what happens. How can this be true? The answer is that TIME is what changes. Space and time warp and twist themselves to accommodate the necessity of an invariant speed of light. This is the basis for phenomena like time dilation and length contraction.
one of the easiest examples is jumping in an elevator
if you sit in an elevator that is riding down and you jump up.
From your point of view you jumped up because both you and the elevator was moving down at the same speed, but for someone else watching it you were falling down the whole time
it wont give you momentum though
You're all a bunch of retards
Literally the in game (and common sense) physics:
If the top plate smacks into the platform and stops dead it's b
If the thing just stops before smacking it it's a
If your frame is accelerating you'd see the world accelerating at a similar rate towards the other direction with seemingly no force acting on it
>I CAN'T REFUTE YOUR ARGUMENTS SO I'LL JUST MAKE IT LOOK LIKE YOU'RE RETARDED, THAT WILL MAKE ME RIGHT.
None of you have answered the question.
Everything around the bullet is carrying momentum. So when the bullet stops by crashing into the wall, all of the momentum carried by everything else is gone, and nothing in the world "wobbles" due to this change. What explains this?
If the box is not moving towards the portal itself then why would the box without any momentum shoot out of the fucking portal? The surface with the portal has the momentum not the box itself.
So the cube remembers its original universe somehow? Absurd. Once in it obeys the laws of motion. Unless of course you would claim the entire universe will feel a big shake in the opposite direction.
if you look through the other portal, the box is moving towards it
I was just explaining relativity here
What does give the momentum is the fact the exit is stationary while the entrance is not.
If you attach the GOPRO to the door, relatively to the door the object enters the door at, say 80MPH and it exits the door at 80MPH,
And whenever the exit is stationary or not the object must still leave at the speed of 80MPH
And if its moving at 80MPH out of the portal, unless there is some force that can stop it (gravity, friction, etc.) It will continue to move at 80MPH
FUCKING MAJOR IN PHYSICS HERE. You're all wrong it's fool I was just pretending to be retarded
The bullet reference frame is non inertial. The moment of stopping means we have an accelerating (deccelerating) frame of reference, within which F=ma and conservation do not apply. Within noninertial frames you must apply a correction of "fictituous forces", which is what centrifugal coriolis and the force that makes you lighter when the lift stops at your floor are. Check the wiki page on fict. forces.
I'm no physics master but I don't think it works that way.
Momentum isn't a property that things "carry", it's a measurement comparing things to other things, which depends entirely on what you compare it to. From the bullet's perspective, the world doesn't stop, the world just carries on in the direction it was going with a tiny dent in the wall.
According to the laws of motion, if an obect suddenly stops accelerating to meet YOUR momentum, then between you and that object there will be no momentum.
In this case, the two objects are the cube and the ENTIRE PARALLEL UNIVERSE, which stops to meet the momentum of the cube.
This has been debunked a thousand times. Why do you keep posting it?
It has to be A because the portal bends space in a way that each side of it is continuous, so there's no difference in walking through the portal than moving through any other part of space. It only looks differently through our perspective in the third dimension, but the hula hoop is just our limited perspective of a higher dimensional space that's connecting seamlessly.
This question is entirely analogous to stepping out the door of a moving car. You go from sitting still to suddenly scraping along the road.
To reiterate, your question has been asked. "if i run around at a non constant velocity in a room, things around me will appear to accelerate and deccelerate with no force. How is F=ma?"
And the answer is that the second law as it was initially formulated does not apply to accelerating frames of reference
Not true if the car was staying still and the outside was actually moving at a fast pace.
No it isn't because you're moving with the car at however fast it's going. You're standing still here while a portal is coming at you
We absolutely have explained it. "everything around" doesn't have the momentum
the case in OP is different because of portals, blue portal stays in place so if the cube enters it at X speed so no matter what it must leave it at X speed.
In the hoops A fags love so much the cube is still coming out the other side of the hoop at X speed RELATIVELY to the hoop
>Your frame of reference must not be an accelerating one for basic relativity to work
Relative physics can accommodate acceleration.
Consider the following example (pic related):
A man sits on a carousel with a ball. When his friend comes into view, he throws the ball to his friend. The man has a good arm, and throws his ball perfectly tangent to the circle's perimeter, in his own frame of reference.
Because the the ball was thrown tangent to the carousel's perimeter, Guy B sees it fly in a straight line towards him. Similarly to how if you spin a ball on a string and let go of the string, the ball flies away from you in a straight line.
However, the man who is on the carousel does not observe a straight-line motion of the ball. He observes it curving away from him as he rotates along with the carousel. This is the Coriolis force in action.
After the carousel ride ends, Guy A and Guy B get together and argue about their observations. Guy A insists that the ball moved in a straight line. Guy B insists that the ball curved. Who is right, and who is wrong? The answer is that NEITHER are wrong. Both are correct. Acceleration, force, and energy are relative quantities just as momentum is.
Your argument was refuted, you are just too stupid to see it.
>if the car was staying still and the outside was actually moving at a fast pace
Try to actually imagine what you're describing. Sitting in a car as the world zips past, open the door and look down and you can see the road blurring with speed, and you step onto that.
>Everyone I respond to is the same person
If you toss a hula hoop over your head, from the perspective of the hula hoop, you ARE moving. You are moving with a speed X "entering" the hula hoop, and you move with the same speed X when "exiting" the hula hoop. Same with a portal. If the portal is moving toward you, you ARE moving with some speed X from the perspective of the portal. And therefore you exit the portal with that same speed X.
The answer is B.
>Yea Forums attempts to teach rudimentary 18thC physics
>an object that has no energy will magically pick up energy after passing through a hole even nothing is actually moving that could possibly transfer its energy to it
t. everyone with ape tier intellect
>wojack poster is fucking stupid
wow what a shocker
Guy a's point of view is that it curves? That seems like bullshit. If you're throwing it at the right moment from where guy A is accelerating straight towards guy B. Then it would be a straight shot for him too, the only difference in perception would be that he's fucking on a carousel so of course it would look fucking weird.
> he forgot that portals never conserved energy and are basically perpetual motion machines
Imagine a little box floating in space. No energy. Suddenly, earth goes right by it. We all see the box moving to the opposite side of the Earth's direction, and then it crashes into a building like it had all the momentum. What the fuck. But it had no energy? How could it happen?
I bet you're one of these idiots who stands in a glass elevator and thinks the world is moving all around you.
this, it is only hard to see because the universe is the street and it is the car at the same time
>Guy a's point of view is that it curves? That seems like bullshit.
It's not bullshit. It's literally the exact same thing that causes sniper shots to appear to curve when you fire the bullet. High school dropout marines can be made to understand this concept and apply it in their day to day jobs. Why can't you?
en.wikipedia.org
that's the point
that's not at what's happening.
Earth isn't moving, the box isn't moving. Only a portal is moving. When the box passes though the portal there is 0 energy for it to crash into anything at all. it's at 0 portals do not move universes.
The ring of the portal is moving but the bit in the middle isn't because it's just another part of the room being folded through space.
Mostly because I'm skeptical of what people have to say on Yea Forums because most of the shit I see here is retards instead of someone with actual knowledge behind their claims.
So alright perhaps you're right but can you explain to me what that means for the box and portal?
>It seems clear that if the platform underneath the cube were moving upwards, towards a portal, the cube would fly out the other end
it wouldn't
>portals do not move universes
Source. They do.
Literally in the tutorial of portal 1, said by Glados:
>Now we will see how portals effect the speed objects of that pass through them or, rather, how they do not. Momentum, a function of mass and velocity, is conserved between portals. In layman's terms: Speedy thing goes in, speedy thing comes out.
Nothing is moving in this situation. There's no momentum to inherit from anything.
did 4chins shat itself again
semantically that is exactly what is happening you middle-school dropout
>Only a portal is moving.
Which portal is the moving one in the OP?
Orange or blue?
What if I told you that the experiment is happening on an elevator that is moving upwards and the top piston is static?
What if I told that the Earth is moving at ridiculously high speeds?
Except there's one thing moving. The portal.
snake pretty much managed to get into a moving car at 1870127841685184 km/h,
what would happen?
Guys we are arguing about something where our physical laws that we know it do not apply. We have no idea how portals would be like in real life so this entire problem seems impossible to solve.
I still think A is most likely but that all depends on how the fuck real life portals would even work.

It's a hole. It's an absence. It's like a doorway. You can't walk through a doorway and have magic impart momentum to you as if you'd been smacked by something physical.
Portals don't really move because both sides of the portal is effectively the same location at any point in spacetime. Hence you can stand halfway in and not be ripped apart.
You would if the doorway (to another world) along with all of its insides were moving towards you.
You're looking at it wrong. Say you're standing under a moving portal and the secondary portal is perpendicular to the ground. As the first portal comes down onto you slowly, what would an observer on the other portal see? They would see you coming out slowly out of the secondary portal, meaning they would watch the portal slowly give birth, as your body "pushed" your head out of the way to make room for you to come out. So you'd have some, albeit very little, horizonal momentum. Now imagine the first portal is coming at an incredible speed, suddenly your entire body would have to be shot out of the secondary portal at a ridiculous high speed, from them the inertia takes care of the rest and you end up being shot a long distance.
walk out of a moving bus
Literally in the game
>Portals can be seen changing the velocity/momentum vector of an object when placed at an angle, as an integral way to solve the puzzles
Portals do not conserve momentum relative to the environment. They only conserve momentum relative to the portals themselves.
Well not exactly. The world is moving towards you. Even if it was moving at light speed, you'd feel nothing and unless your head was touching anything you'd be absolutely fine. Well I mean except for your head falling forward since your previously upright head is now being pulled down forehead first onto the floor.
Let's assume the answer is B, and apply that to a case where the two portals are still and an object is moving towards the entrance (all of the cases in-game).
From the point of view of the object it's the portal that is moving towards it (relativity), and thus would gain momentum if B is true, that means that any object going through a portal comes out faster than before entering.
In the game at least that's not true and so it operates per answer A, how it would effectively work in "reality" is up to interpretation I suppose.
Doorfags, your argument has been BTFO'd multiple times by the fact that both the entrance and exit of a door is stationary, whereas in this scenario the entrance is moving and the exit is stationary.
Nice headcanon, fag.
You just proved why B is right. A moving doorframe implies that both the side you're going in and the side you're coming out are moving at the same speed, so they're not moving in relation to each other. The equivalent comparison would be a mooving doorframe and a floor attached to it on the other side. Would you magically be standing perfectly on the other side, or would you stumble because someone quite literally threw a moving floor under you? It would be the equivalent of jumping into a moving train, while you're techinically not moving horizontally, to and observer inside the train, you'd going backwards, but it's just the train that's moving under you. Inertia is a bitch
>Though I suppose it would make trips through portals that are really far apart pretty dangerous. Like really far though.
How so?
The portal may be moving towards it from the object's point of view, but it will also move away from it once the object moves through the portal. B remains logically consistent.
What is actually moving if the portal is just a zero width wormhole? What is there to move?
Yes? Do americans really don't understand this
>nonzero speed
>That's wrong. It would detect speed
Are you mentally challenged?
The universe contained within the portal.
That's just straight up wrong. You go into portal 1 at x speed and come out on portal 2 at x speed in relation to it, not the world. Let's say the portal 1 is not moving and the portal 2 is moving forward at 10m/s. What happens when you jump throught portal 1 at 10m/s? would you come out at 20m/s on portal 2?(the equivalent of throwing a ball forward from a car) or would you just plop onto the ground since both you and the portal are moving at the same speed? The answer seems obvious to me.
big if true
Afags are braindeads
Doesn't that just literally break everything?
There is no reqason it would be B. the air would only affect the cube by the cubes own size. It wouldnt be powerful enough.
If B was the case the walls would fly off whenever you jump through a portal
What about this?
Ask yourself what it looks like.
The carpet on the car would be stationary to you.
WITHOUT A REAL LIFE REFERENCE OF HOW PORTALS WOULD WORK THERE IS NO ANSWER YOU FUCKERS
It could be both depending on how exactly the portals work in general. We can't even call on game physics here because portals don't fucking move. This is unsolvable
Portals themselves do not exist in real life for that very reason.
Exactly. You would look inside the portal and the inside of the car would appear stationary and it would be the outside of the car that is moving.
>From the point of view of the object it's the portal that is moving towards it (relativity), and thus would gain momentum if B is true, that means that any object going through a portal comes out faster than before entering.
If you're actually applying relativism, then you should know that the object is not actually moving from its perspective. Instead, everything is moving around it.
From the perspectives of the cube, the bottom platform, and the portal platform, there is no difference between the two scenarios.
The cube will see the portal moving towards it, the bottom platform will see the portal platform moving towards it, and the portal platform will see the cube/bottom platform moving towards it. The difference can only be observed by an external observer.
Furthermore, the first scenario shows the cube literally popping into existence on the other side of the portal. Can A-fags get even more deceptive?
Unlike the hula hoop, the portal itself is not an object of any kind. It's just what folded space looks to you.
So momentum *relative to portal* at entry must be same as velocity *relative to portal* at exit.
The answer seems to be B.
Stationary compared to what?
This whole debate could [possibly] be solved by saying "The platform you're standing on is what moves you, not the platform with the portal, because at least you're being pushed via an external source, and not just being consumed with no current velocity".
At least, that's how I'd see scenario B playing out [in the WebM]
This stupid image is proof Yea Forums is mentally defective and doesn't even understand the concept of gravity. If a quickly moving doorway or hoop passes through you are you going to suddenly get catapulted? The answer is no you literal retards. The only movement that would result from this image would be a shaky plop in between a and b from the force of the slightly larger moving platform crashing into the stationary one. B would only be the case if the lower platform was moving up and stopped.
