A or B?

>>376965008
A, we've been through this.
Portals only keep the energy of an object with the energy is from the object, not the surface a portal is on

for the last time its B

I can prove this as well: lets say the scenario was turned upside down, and the blue portal doesn't move, the box then falls into the blue portal at the same velocity that the blue portal crushes down in the original scenario, after the box falls into the blue portal at that speed, it keeps its speed for a moment after the gravity is equalized after leaving through the orange portal, thus it is propelled out at a certain speed

The momentum of the pylon going down launches the cube

>>376965008
B
The cube moves from sheer force of companionship alone

>>376965008
B because when the cube is emerging from the portal its also moving.

You cant just stop that movement for no reason unless you think physics is a big load of bull.

Jesus fuck, I'm so sick of these god damn threads. It's A because portals function as doors. If you drop a door onto someone, do they suddenly launch out the other side of that door with the same force with which the door was falling? No, they don't. They come out on the other side of the door. This is simple shit and everyone constantly makes these retarded threads over a concept that can't even be tested in-engine. Knock it off.

portal 2 has moving portals. its literally the solution to a puzzle. you see moving white boards on a conveyer belt and you need to cut some pipes. put portal near laser, put portal on moving wall. laser slices the pipes.
its a puzzle that directly relates to the end, you cut the nueruotoxin supply so she has none at the end.

>>376965447
You are literally talking about """proving""" the scenario by changing it entirely. Making the box fall due to gravity acting on it means that it has had a force as it moves through the portal.

In the original scenario, the box has no forces acting on it as it goes through the portal, meaning it doesn't fly outward.

A-fags cant even compete with this

It has to be B because the cube necessarily exits the portal at the same rate it went into the portal. It's all relative to the portals. And yes, hula hoops work the same way.

>>376966545
Portals are like door frames. You keep your momentum, but you dont get momentum. If a door frame rush toward you, you dont gain speed.

>>376966312
and? it means in the world of portals, portals can move

>>376965008
Let's say the blue portal is moving at 60 mph, that means that the cube would come through the orange portal at a rate of 60 mph, so why would that momentum just stop existing once the cube is fully through?

it's C, the one where no one knows the answer because no one here plays vidya.

If the portal is just a hole, it won't move.

If you put a ball in your hand, make a ring with the fingers of your other hand, and slap them down around the ball, nothing will happen.

>>376966661
>muh door frames

why do you keep going on about door frames, it's like an obsession holy shit

>>376966406
Reference frames are part of the basis of general relativity you dolt.
From the reference frame of the portal, the box is the object in motion, and this frame is equally valid.

>>376966731
Because it's a door. The portal is a door. The momentum doesn't just "stop existing", it continues as the pillar which the portal is on slams into the ground, resulting in damage to the pillar.

Why does every A-fag ignore the fact that from the perspective of someone standing in front of the orange portal, the cube is moving? So why would it just stop moving?

Very basic relativity principles show that this is the exact same as if the pillar was moving the cube up into the portal. It's a simple problem of "does the inertia of the cube allow it to leave the ground?" You don't launch into the air if you're in an elevator and it moves up and then stops, but you sure do if you're in a catapult arm which moves up and then stops.

The real question is if you were in a game show, and the portal was behind one of three doors.

>>376966331
A isnt possible because there's nothing holding the platform up and C is only possible if A is true, so it's B

File: portal-cube.png (17KB, 1152x648px) Image search: [Google]

17KB, 1152x648px

B. Think of the two points of space being occupied by different parts of the same cube. Where it starts (blue side) it's still sitting, so there's no velocity. Where it comes out (orange side) the cube is moving, so there is velocity, and when it comes out completely that stored kinetic energy would be enough to propel it. It's kind of like it's being pulled out of the portal as opposed to pushed through.

>>376967138

it comes out the other side of the hole at the same rate
in your senerio the output side of the hole is moving at the same rate in 1D with the input side so the object moves out at the same rate
if the output side was stationary while the input side was somehow not it must find a way to still exit the output at the rate it enters the input
if it enters at a speed relative to the input of x, it must exit the output at a relative speed of x
since the output is stationary it would launch out as the speed wouldn't magically go away after it finishes passing

That's the point of bullshit made up fiction like teleportation. It represents a fucking reality breaking hole that says "X go to Y". That's it. It doesn't exist for energy to be applied it, and it can't transfer energy to other objects. It's empty air, it's not real. From the perspective of the portal, X and Y were set in stone when you placed them. Portal speed just impacts the X to Y conversion speed.

Speedy thing goes in, speedy thing goes out. Motionless thing goes in, motionless thing goes out.
The cube would be moved by the air being vacuumed up, though.

Then how does it get out of the exit portal? If someone is standing stationary in front of the exit portal, the box is going to hit the person. So clearly it was moving.

>>376967419
No. if you dont touch the ground on the outside of the portal, you are grounded by gravity on the inside. If you place a step outside while the portal is moving, you will have friction that will make you exit to portal.

>>376967635
Here is what is happening with portals.
https://www.youtube.com/watch?v=ucKk_H71B74

The doorframe goes toward you. The rooms on both side of the frame is not moving.

A because the cube does not have momentum. Imagine dropping a hula hoop over the cube, it would not cause the cube to fly up into the air after passing through.

When you enter a hole at 40 miles per second, do you exit the hole at 40 miles per second or do you exit the hole at 0 miles per second.

>>376965008
The gif literally proves that both scenarios are possible, in the gif's own fictional physics. But it doesn't/can't exist in real life therefore the argument is moot.

>>376967649
Placing a step outside the portal is moving towards the portal. In this scenario, the portal is moving to you. It's the other portal that's stationary. So how are you going to get outside of it?

>>376967783
>Bfags pulling shit out of their ass
Post source or fuck off.

>>376967956
you exit the hole at 40 miles per second.

B

>>376967830
But in my example of someone standing in front of the portal, the cube hits the person, so clearly one of them was moving relative to the exit portal, and it's not the person.

>>376967956
You dont move. The HOLE is moving. If you throw a circle around a person, you dont move with the circle.

>>376967958
>The gif literally proves that both scenarios are possible, in the gif's own fictional physics.
You mean someone drew two scenarios and you think it looks fine.

>>376967956
The cube isn't moving. It enters at 0mps and would exit at 0mps.

A-fags why doesnt the box exiting the portal count as movement?

The top of the box clearly moves a box length out the portal so it is moving.

>door/hoola-hoop/hole fags

Alright, you guys got us, you've successfully trolled us.

>>376968061
Oh, is the hole moving? That's not the scenario in the OP then, is it?

>>376968054
No. Just two things trying to get in the same space. Neither are moving. Imagine a conveyor belt moving a box in the face of a guy. The box does not move. The guy does not move. The box just approach and hit the face because the face is in the way, but the box does not have any actual velocity or speed attach to it.

>>376968061
In that example, both the "entrance" to the circle and the "exit" of the circle are both moving at the same speed.
Portals change the problem entirely.

>>376967830
That example would mean the angled surface where the orange portal is placed is also moving just as fast as the piston where the blue portal is placed.

>>376967956
if it's the portal moving at 40 mps you just materialize on the other side faster, answer is still A, so many dumb kiddos here

>>376968125
>would exit at 0mps
Did you even watch the gif? It has velocity as it exits, then as soon as it is fully outside of the exit portal, all of its velocity goes away.

>>376968125
cube = 0 mph
portal = 40 mph

0 + 40 = 40mph

>>376968092
>You mean someone drew two scenarios and you think it looks fine.
Yes, I would literally fuck those 2 sexy ass scenarios but what does that have to do with what I said?

>>376968125
The cube is pretty clearly entering the portal at the same speed of the portal.

>>376967393
Some people get dizzy from VR, so yes.

>>376968269
>this is the intelligence of Afags

>>376968205
It is?
The hole is in a press
The press move the hole down toward the cube.
The cube will simple stand in the platform until it slowly appear outside of orange by the top first, and then gravity will pull it down toward the floor of orange when the center of gravity will pass through.

Anon, there is no distinction here. Any momentum is just momentum. There is no "portal" momentum or "object" momentum.

Portals transfer momentum, else the game would be impossible to finish.

And I'd love to see where you're taking this "portals don't transfer their own momentum", however asinine that is, from.

fucking lmao, you even say the box approaches this hypothetical stationary object, yet someone it isn't moving.

>>376968283
The portal doesn't transfer any energy to objects going through. It's just a hole.

>>376968435
Look at the orange hole. Does that look like it's moving?

>>376968450
>Portals transfer momentum, else the game would be impossible to finish.
They no not transfer momentum at all. Post an example of a portal transferring momentum.

B creates energy which goes against the law of conservation of energy
A appears to create energy as well but it fixes itself magically once it finishes with no explanation as to how

the only true possibilities is that
it is that it would appear as B but the portal must be maintained by energy equivalent to energy that passes through it
it would appear to be A and the portal does not operate as a singular plane but rather at least when in motion warping space somehow to create a bubble around entering ridged bodies relative to the input side until complete transfer
or of course, it is not possible to generate portals that have any motion relative to each other

be default it would be the last option since this is not real (yet)

>>376968450
No, there is absolutely a distinction here. The objects you launch through portals stay moving in the game because they started out moving. If you drop a cube through a portal at 40 MPH, it will exit the other portal at 40 MPH and then any difference in gravity will begin to act on it. This is not the same as shoving a portal into something at 40 MPH, because the object itself is not moving in this instance. The same concept applies in both cases: the object exits the other portal in the state that it entered the first portal, and then any change in gravity begins to act on it.

>>376968450
BUT THE CUBE IS STANDING STILL DUMB B/NIGGER
>>376968395
ok materialize was the wrong word, you just make the transition faster but once its complete you don't just get propelled 40 mph just because the 1st portal had that speed

>>376965008
The pillar never touches the cube. Before they exchange momentum the cube is always already trough the portal. Since the portal acts like a hole all momentum crashes into the platform and none is carried trough the portal.

Literally the opposite would be if the lower platform would smash into the upper platform with the cube which would carry the entire momentum.

>>376968243
Okay but what if you had an aeroplane on the conveyor belt, would it make it through the portal?

>>376968521
Exactly. Neither things are moving and yet they both approach and collide into each other. Two immobile objects collide because the space between them changed, not them.

This is portals.

>>376968524
The portal is moving 40 mph towards you, and thus you are entering it at 40 mph because MOVEMENT IS RELATIVE. You must exit the portal at the same speed.

>>376968608
It's not. Which make the problem easier. You just slowly appear in a diagonal in the orange portal.

>>376968754
This is absolutely not true. It's just a hole, not a hole that somehow transfers the movement of the object it's on to the objects going through it.

>>376968754
this

>>376968524
https://www.youtube.com/watch?v=MjeMOhb9enI

>>376968636
actually I forgot one:

or of course the law of conservation of energy is wrong as physics is only based around observable science and it cannot be definitively proven that energy may be created in this fashion which would logically result in B as speed of exit must be equivalent to speed of entry

>>376968853
You must leave at the same speed you enter something. You enter the hole when it is dropped on you and leave the hole when it passes your entire hole at the same speed the hole is dropped.

>>376968797
>It's not.
So now go back a couple of posts again and see what that entails.

>>376968910
Which work if the cube is THROWN in a portal. Not if it's immobile.

>>376965008
"B" fits the most with what we know from the game universe if you ignore the no moving portals rule. It's all about relativity, if the the cube enters and exits the portal at the same rate, it should fly out. Another way of thinking about it, is the surroundings moving past the cube, not the cube moving through the surroundings, both of which look the same in our point of view.
A only works if portals selectively transmats materials and doesn't have to account for air and other materials at the rate they are being transferred. In this scenario the portal transfers the cube while calculating and applying force on the cube equal to it's speed minus the speed of the portal. Which would be zero and result in plop. This ultimately is a 3D printer that accounts for the speed of scanning, not really a portal

>>376968942
>You must leave at the same speed you enter something
Right, which is zero speeds per second. The pillar that the portal is on is the thing that carries all the momentum in the example.

A - the box exits the portal at 1 mph and is pulled to the ground by gravity instantly
B - the box exits the portal at 1mph and is pulled to the ground by gravity


60mph test - the box enters the portal at 60 mph
A - the box exits the portal at 60mph is pulled to the ground by gravity instantly
B - the box exits the portal at 60mph and is moved across the room


No matter what the box has mass that is exiting the portal. Does that mass have momentum?

The "who" is moving is completely relative in physics, but it does not matter because momentum is momentum. The same way a car hitting you at 50 mph would hurt just as much if you ran into a parking car at 50 mph.

>>376968985
It's not immobile when it's coming out the other side, see >>376967305

>>376969087
It's not exiting the portal at 60 mps. It just appear there at 60 mps. But the ground where the box is standing, is still original place.

>>376968993
for your A argument:
but then how will outputted surfaces be moved from their locations as newly outputted surfaces appear through the portal? this would either require movement, which would somehow require a generation of energy, or the condensing of passed matter's location, which would also modify universal energy

>>376968718
Okay, I don't think either of us are going to convince the other.

>>376965008
The air pressure is not enough for B scenario though I doubt the air pressure wouldn't move the cube more than A is showing. The air pressure is the only thing that is able the affect the cube.

False equivalency, there is no running into anything here. The portal is literally just a hole that exits to another hole. There is no change in momentum for the cube.

No. Two TOTALLY different scenario.

In 1 the cube is just on a plaform with a holahoop falling on him. He will just see what is on the other side of the hoop.

In 2 he's MOVING toward the holahoop and the holahoop will abruptly stop when it collide with the other platform, which force you to enter it with force.

It's not moving, it's pulled by gravity down and it will fall down due to the center of gravity changing.

And that is precisely why it goes flying.

And that's because, and repeat with me now: "Movement" is relative. If portals defy the laws of physics in this regard, I'd love to see where you got that from.

>>376969373
If the cube doesn't move, how does it get to the other side of the portal?

>>376968636

Even stationary portals pull energy out of their ass. Floor portal + ceiling portal + water-wheel = infinite energy. It should not be surprising that moving portals would pull energy out of their ass too.

The alternative is pulling matter out of its ass. If the cube does -not- exit the portal at the same speed as the falling portal, parts of the cube's matter will be destroyed (if the cube comes out slower than the falling speed) or duplicated (if the cube comes out faster than the falling speed).

Gravity did 100% of the work in that jump. Portals do not push you out. Any speed you gain moving through a portal is due to gravity. Think of it as falling though the air. Try that same thing on a flat plane and nothing will happen. Because portals are doors. They are holes and convey no energy.

>>376969475
Yeah except in either instance when it comes out the other end it's moving out of a stationary hula hoop at whatever (relative) speed it went into it. The previous perspective doesn't matter any more at that point.

>>376969473
I wanted to focus on the cube, which is and isn't moving in different parts of space, which is where the confusion comes from

>>376969558
How does the word "pulling" not imply movement?

>>376969610
It does that because the space that the cube was occupying is replace with the space just outside the orange portal; it's not the cube moving but the world around it

>>376969445
>>376969424
Okay. Learn what portals are first.

Okay now, You stand on a physical object. A hole fall on you. The hole connect to another place in space. When the hoop first go through your head, your head dissapear from where you were and then appear in the exit of orange.
You have a floating head that appeared on one side, and body standing with no heads.

Then the hole keep moving down to show your torso. You are now being pulled strongly by two gravitational forces, but you are still standing still on a plaform.

Then the hole touch the base of your feets. You are STILL touching the metal base you were touching on the other side of the portal. You are at both places at the same time. Because of gravity, depending of the orientation of the hole, you will either fall or not.

But you do not MOVE at 60 mps. You just slowly appear in another space at mps. If you cant understand that concept, you might not be qualified to be here.

>>376969841
But it is like a hula hoop. How is that not a valid argument?

>i do not know what conservation of momentum is

Nobody is saying that Portals "push you out" you absolute retard. The fact that is that if Portals didn't conserve your momentum, you'd fall limply 90 degrees downward after that jump, instead of shooting out of it.

>>376969729
>cant explain something without describing other objects

autism

These threads never cease to amaze me. Regardless of who is right, these threads make me understand why we still have flat-earthers five years after the world ended.

>>376969716
You move because of gravity. If the portal was on the ceiling, you would fall off when most of you mass has gone through the portal. So yeah, you move, but you are not actually moving through the portal with any velocity. You just fall down because the earth pull you differently from the other side.

>>376969729
This is entirely backwards. Afags try to cling to a faulty notion of momentum that doesn't apply here if you think about it for a second. Bfags use pure logic which is necessarily true.

Because likening a tiny wormhole in space-time to something as simple as a "door", a "hole" or a "hoola hoop" insults people who say B is correct.

don't portals disappear when the platform it was placed upon starts moving?

I assume this is based on the video game, portal, where orange and blue portals are the design choice

even if the portal didn't disappear when the surface it was placed on starts moving, the portal itself won't actually move along with the surface, the surface will just clip through the portal

>>376969632
actually particles in game go away after passing bumping around the portals for to long, since you know- they're just particle effects
you can probably argue that some matter is being converted into energy as it passes through the portals, but would that still would be a lot more energy then being used so where does it all go?

The cube is moving relative to the first portal, you retard.

What if the upper platform had a hole in the middle instead of a portal? And let's take a light ball instead of a cube. So the upper platform crashes into the lower platform where the ball is standing on. The ball would get shaken up a little from the collision but it would not jump up the hole. For the ball to jump up the lower platform would need to be made out of rubber.

You're not very smart, are you?

Let me reiterate again: Portals do not alter your momentum. You fly into the blue one at 50mph, you show up at the other side at 50mph. This is a fact as well as a game mechanic for traversal in the game.

>>376971143
even if the orange wasn't moving the cube would just fall down and not just shoot trough

Assume Portals are not objects, but some intangible rule called "X to Y". They never move, there is nothing to move in the first place. Beside creation and destruction, you cannot pick up, grab, or otherwise interact with a portal beyond the rule they embody. Therefore the crushing pillar does not interact with portal, because what is at point X is what is at point Y: empty air.

The only thing that matters is that they transfer X to Y. This includes objects and the momentum of said objects. Speed of the portal impacts how fast X is transfered to Y, it does not grant it energy that it never entered with. This is the fiction part of teleportation. How fast they "exist" doesn't grant movement. For all intents and purposes they literally came into being at that location because the bullshit magic froot loops said so.

The distinction is meaningless because it's fictional, but frankly I'd prefer a game where the protagonist doesn't get torn into a fucking meat slurry bit by bit because he got enveloped by a fast moving portal.

Though it would be fucking hilarious if a developer made a portal gun that could switch between A and B. A for utility, B for pulping some poor faggot.

Either way makes sense, depending on whether you take the entry portal or the exit portal as the definitive reference point

If the entry is the reference, then it falls out, if the exit is then it flies out

The blue portal has no momentum. The pillar moving has all the momentum. Therefore, it's A and the cube doesn't move since there's no energy transferred to it.

Except yes, because if you don't, you're not coming out the other end. If you accept the fact that the cube emerges out the other end, you've already accepted relative movement. Really, what A is is the cube suddenly coming to a halt after moving out of the portal.

Portals may look like simple doorways, but there is in fact a threshold there, invisible and intangible, that separates two frames of reference. It's essentially like stepping into a pocket universe, that just also happens to be our universe. But you can already accept that gravity works different the moment you step through a portal. Why not movement relative to the environment? You are in a new frame of reference.

>>376966078
My hypothesis is that the entire room moves up and the blue portal remains stationary. Therefore the cube has inertia and continues to move.

>The blue portal would have 0 impact on the exit velocity
If it did, the cube would go out flying.

>or go so far as to double it.
u fucking wot

>>376971650
This is wrong, the cube doesn't move at all. The entrance of the door just goes past it and then it's exited the door frame.

I used to be a staunch A supporter, but I understood B's perspective awhile ago and it made way more sense. The outcome also entirely depends on the speed of the blue portal, but assuming it's moving fast enough, it's B.

Imagine you're standing next to the orange portal, staring into it. You see down below the cube. The blue portal starts moving towards the cube, and from your perspective, the cube is now rising upwards. It rises upwards and as soon as it comes out of the orange portal, it will pop off due to the "upwards" movement. Another way you can illustrate this is by holding something (like a pen or your phone) on your palm, quickly raising your palm upwards and then stopping. What happens to the object? It pops off due to the stop in movement, but inertia pushes it.
Why do we interpret it this way instead of the object moving? Because the blue portal is what's moving here, not the orange one. Look at it as if the cube is moving OUT of the orange portal, NOT going into the blue portal.

>muh hula hoop / doorway
It's not a hula hoop or a doorway. It's a portal.

>>376971037
Look how it's literally exiting the portal at the EXACT same relative speed it went in.

It would still have moved the thickness of the platform to the left though

Within the space of the room it has moved, it exists in a space that it didn't previously exist. In your doorway scenario your position within space remains the same as the doorway moves around you, in the case of these portals the cube's position within space changes, which means it moved.

>>376972005
not analogous in any way

Are you dense? It bounces off the portal because the other end of the portal is now the solid wall of the piston meeting the floor. Stop making up irrelevant shit.

>There never was anything to negate.

Within your perspective that is lacking the understanding of how momentum works and how speed is relative, yes.

But unfortunately for you, that is not true. So, in the end, that is an example that proves absolutely nothing, except that you do not understand how you don't understand how relative speed is in physics.

>>376971994
No, but the objects they're on can have momentum. Like if you had a situation where Chell was standing under a pillar with a blue portal on the bottom and the pillar slammed down "around" her at 40 MPH, no matter where the orange portal is, she would come out of it at a standstill and then gravity would begin to work on her.

That's how A would work though, not B. As everything "stationary" would be warped into the same Y. Whereas with B it would move away from Y at the same speed it went in, making room for the rest of you.

>>376972051
To be fair he is think about the wrong referencials.

>>376972059
Both sides of a doorway are either stationary or moving, you can never have one side of a doorway in motion while the other side is stationary, which is what is happening with the portals.

>>376972242
I can't pin down how this relates to personal philosophy, but I'm going to assume that you're a happy chap and that this somehow informs your life.

Good on you, anon.

>>376972162
well i also said the portal keeps moving which isn't true in the original example, mhm
well my answer is still A cuz magic and shit

>>376972160
And this is predicated on what, the assumption that portals apply momentum through some sort of static field?

Use your fucking brain.

>>376972051
So we went from "speedy thing goes in, speedy thing goes out" to "portals move things without speed"?

>>376972303
the platform is a cake, and the cake is a lie xDDD

>>376972162
>portals can make platforms disappear

try again

>>376972258
No, it's not like space somehow warps there. The objects simply appears through the orange portal based on how fast the blue portal was moving. If the blue portal falls on it at 50 MPH, it appears through the orange portal much more rapidly than if the blue portal fell on it at 5 MPH, but the object does not start moving at either 50 or 5 MPH in either case.

Its B. If it were A, how could the cube move out of the other portal at all if it "has no momentum"?

>>376972194
It's because you are thinking about a different movement being measured by other means. There is no kinect energy of force being applyed. The movement you are thinking about can't maintain itself without it.

>>376972162
Ignoring the disappearing platform, the momentum that Orange had HAS to show up at Blue.

And that is because it doesn't matter who is moving, be it the portal or object, since speed and momentum is relative, and because portals DO conserve your momentum, the object would absolutely fly out.

>>376971953
By breaking the laws of physics.

>>376972478
just assume it's 0G in a vacuum and the black thing doesn't exist, only this time in the bottom right the cube would be floating in front of the 1st portal

>>376972303

>>376972484

That's movement. It was in one position and it is now in another position. It has moved.

Portals don't conserve anything, my man, they're just holes linking two places together. The block does not suddenly begin moving just because a hole went around it, but it DOES begin moving if upon exiting the hole it ends up in a position where gravity can act on it.

>>376972683
Incorrect. The object does not move.

Because that's how fucking portals work. If an object is halfway through two portals and one of the portals breaks, the object is pushed out one end and stops perfectly at the edge. It doesn't go flying across the room. Portals exert just enough force to move an object out of it.

>>376972746
Thats if both sides of the hole have the same speed and movement.

If entrance and exit are moving at different speeds that no longer applies

>>376972362
the difference between me and the "half full/half empty" shit is that im looking at a whole picture and taking in only the important info. if there is reason to debate any further then so be it but until that reason comes up then it is irrelevant

i could say the answer is "who cares" for the portal issue, but realistically that is an information restricting answer.

for instance: we know that a glass of water has water regardless of amount. this is clear information. in the portal question we have 2 outcomes (more in fact) that can only be replicated under certain conditions, of which we do not have proper access to so until that time comes it is a question that cant have an answer, only theorized results

i can tip a glass of water, and it may fall, it might not fall. but what matters is that i tipped it and depending on how it was tipped it will lead multiple ways. it could stand back upright and not spill, maybe itll splash back and spill, or maybe itll fall over and spill


as for philosophy thats your call im just here to bring my side to the table. make of it what you will because realistically we wont have any answer outside of "this is a problem that exists"

>>376972553
Two wrongs make a right!

>>376965810
what momentum? the cube was stationary, it had no momentum and the portal transfers no momentum to it as it functions like a falling door. the only momentum there is the pilon's which is dissipated by the impact but has no effect on the cube.

>>376972779
For some reason this reminds me of the infamous "during the stoneage"-page of Sonichu.

"Have you tried explaining it using hula hoops?" should seriously be a standard response to retarded shit around here.

>>376972194
If you moved into the portal, it transferred or "teleported" you from X to Y as fast as you moved.

It the portal envelopes you as you stand stock still, it transferred you from X to Y.
Atoms at X now exist at Y because that's what the portal does, that's what fictional teleportation is.

You existed at X, and now you exist at Y without any physical movement on your part. How fast you exist at the other end does not mean your scalp gets torn off and flung at 100 mph.

>>376972873
It does still apply. A portal moving changes nothing, as it's still just a hole in space that links to another hole. A hole has no ability to confer anything to anything else; it's empty. The only thing that moving a portal changes is the object that the portal is on. That object will slam into the ground. That's it.

>>376972862
ITS B BECAUSE IM RETARDED XDDD

>>376972746
>Incorrect. The object does not move.
Either it moved or the room around it moved, because it is a position different from it's previous position. Given that the orange portal is stationary the room could not have moved, so that inherently means that the cube moved.

>>376970119
Maybe its because the word portal literally means DOORWAY. It's called a portal because its a doorway in the dimension.

You must exit a hole at the same speed you enter it. If a hole is dropped onto you at 70 mph, you enter said hole at 70 mph and exit at the same speed.

Let's get some perspective here.

>>376972484
Objects don't simply pop into existence on the other side in their entirety, Anon. They go through atom by atom. If it doesn't move, it's going to implode when it runs into itself.

>>376972862
B but it would have to lift the mass on the other side of the portal so it wouldn't go as high if the portal didn't stop going down prematurely
obviously

>Portals don't conserve anything, my man, they're just holes linking two places together.
And that is precisely why it conserves momentum. For fuck sake people, this is a MECHANIC within the game.

https://youtu.be/ahx-dn_o6sc?t=4m11s

>The block does not suddenly begin moving just because a hole went around it, but it DOES begin moving if upon exiting the hole it ends up in a position where gravity can act on it.
Nope. Whatever momentum it had, it remains the same, not just "gravity". Just like how if you toss a cube into a portal, it will come out with the same speed, and then eventually accelerating.

You don't seem to understand how speed is RELATIVE. It doesn't matter "who" is moving, as long as there is movement.

And if Portals don't apply to that, I would LOVE to see where you're getting that from.

ALRIGHT FAGGOTS
last time

What happens if the entrance portal is moving to the left at 60mph and the exit portal is moving right at 60mph and the box is stationary.

>>376972826
>If an object is halfway through two portals and one of the portals breaks, the object is pushed out one end and stops perfectly at the edge.
BUT I THOUGHT PORTALS DON'T CREATE ENERGY?

>>376973119
dude what

>>376973168
>>376972538
It conserves momentum but the momentum isn't on the object, it's on the platform. There is no force being applied to the object, no W therefore no /\K variation of kinect energy therefore the cube doesnt fly out

>>376972708
Would love to hear you elaborate on what's the difference here.

>>376973184
The same thing as any other time the object isn't moving: the object doesn't move but comes out through the exit portal

>>376973184
Both A and B fags would say it stays still.

>>376973247
Who are you quoting?

>>376973294
>It conserves momentum but the momentum isn't on the object, it's on the platform

Anon, what part of RELATIVE you do not understand? It does not matter "who" is moving, because SOMEONE is. And that speed will be conserved when exiting the other side.

https://youtu.be/S85nudR6D-Y?t=85
kek

Wait, so what happens if the blue portal stops prematurely and it only gets to middle of the cube? Does the half sticking out of the orange portal elongate? Does the momentum of the top half propel the rest of it out? Or does it just stay there because no force was actually applied to the cube?

>>376973184
Cube exits at a relative speed of 60mph or 120mph to a stationary observer.

>>376969346
It took me a while to come up with a way to refute this, but I think I have an idea. Sorry if it it really isn't understandable, I'm kinda bad at explaining things.
I think the problem here is that you are trying apply newtons law of conserving energy within a single system when we are talking about the (unrealistic) interaction between two different systems connected through portals.
The way I think of it is that; the moving portal engulfs the cube and it's "potential energy", which is converted to actual energy by virtue that it is displacing matter in the new system and it's relative frame of reference.

>>376973294
Even if you are correct, inertia is still a factor in this. Just because the bus you're standing in instantly stops doesn't mean mother earth is as quick to grab a hold of you.

portals are literal fiction, there is no real world equivalent, and to human knowledge are impossible

physics as physicists describe it have no bearing on this fictional depiction of a looney toons style hole in reality

What happens to the air that goes into the portal as it goes down? Does it just stay perfectly still? Fuck A-fags

>>376965008
To all B defenders:
If a portal is on a plane and it connects to a stationary wall somewhere on the ground, when you exit the other side, will you continue moving at the same speed the plane was moving?

The cube itself.

>>376973797

>>376973467
JESUS FUCKING CHrIST
Of course it matters who is moving.

You know what? I think I came up with something to show it.
Portals just links two spaces. a plataform with a portal there is just a fucking tunnel. If it stopped halfwaythru you wouldn't be mauled.

If the ISS suddenly moved really fast and then stopped the astronausts wouldn't get dismembered because they suddenly had energy and movement because the fucking didn't, the iss did.

You know why the momentum of the body is what dictates the momentum of the exit point? becuase if you slowed down or stopped midway thry your body would be ripped appart

>>376973987
Oh wow, what and innovative analogy. Opened my eyes.
