>>377776028
The portal can't move.

None. Portals disappear when the surface they're on moves.

>>377776284
And if they could move B would happen because relative momentum is constant between the portal and the object.

>>377776257
oh right, nevermind then

If the Orange portal is moving then the Blue portal needs to be moving and because of this both answers are right.

There's no logical way to prove this at all.

>>377776334
irl it's A though

>>377776502
Momentum is constant between portals. Thats the second rule of portals.
Fast thing goes in, fast thing goes out.
From the portal's perspective the cube is coming towards it (relative momentum).

Portals require an infinite amount of energy to be created, we know this as there are various ways to create a perpetual motion machine with them which can only be possible if they already take an infinite amount of energy to make.
Since we know Energy = Infinity, let's do a couple of equations.
E = mc^2
As we know c = the speed of light or 299 792 458 m / s, and 299 792 458^2 is 8.9875518e+16, and that Energy is Infinity, the equation becomes
Infinity = m8.9875518e+16
The only way for the equation to match up with one another is if Mass is also Infinity.
Therefore, a portal has infinite mass.
F = ma
We already know m = Infinity so the equation becomes
F = Infinity x a
Any form of acceleration would require an infinite amount of force.
Ergo, the answer is Ѭ, the piston is unable to move as it would take an infinite amount of force to move the portal situated upon it.

>>377776775

Exit portal has no velocity, and neither does the cube.

A is the obvious answer. B is cartoon physics answer, and anyone who picks B needs to stop watching TV.

>>377776028

Think for a moment from the perspective of the blue portal. How fast is the Cube emerging from the blue portal? As fast as the orange portal is falling on the cube.

B

this is a good thread

>>377776028
>>377776028
The answer is A, but it feels like it should be B because of the speed it pops out of the portal

The reality is, is that there would be some air being forced outward through the portal which might make a pop, but the cube is actually still standing still and is also getting air forced onto it by the portal closing in.

Any force you feel from the Cube popping out of the portal is actually just the force of the cube moving through the portal. In order to resist the cube moving through, you'd have to destroy it or the ground that the cube is on, otherwise it will move through and move anything it touches away from it.

This image is probably as old as portal. I'd be pretty surprised if it originated on knowyourmeme, which was literally a month old at the time.

Anyway, the answer is B. If you could do this with a wormhole, it should be immediately obvious that the frame of reference in and out has to be consistent; after all, the object needs to pass through it. The energy difference in the block from the observer's perspective would therefore be lost by the wormhole by their interaction (never-mind the fact that the portal is accelerated after the fact when the piston comes to a stop).

>>377785289

>You assume they fall under the basic laws of physics of real life
Yeah, yeah I do.

>>377788443
Wait, I revise my answer. This is a paradox. No momentum in one frame, but momentum in the other?

I think the obvious answer is A, but if I put more thought into it I would either find out it's B or find out that all the B guys are just trolling, if I know how 4chan works.

Can anyone seriously answer why it would be B? As far as I see it, the Cube has no momentum and thus would drop to the ground immediately, and the momentum the platform with the orange portal has would be lost on impact with lower platform. I've seen the "think of the portal platform as a trapdoor" argument(and, subsequently, it being mocked) but never a good answer as to why it wouldn't make sense.

>>377788464
Drop the sarcasm because after reading your original post you're wrong in a different way. E=mc^2 is the rest mass for massive particle (the equation is not valid for massless particles such as photons). You're assuming a portal is massive then trying to deduce its mass is infinite. However, from this, you're really only allowed to deduce that yes, if a portal were a massive object then its mass would have to be infinite. In your reasoning, you disregard the possibility that a portal is massless.

And frankly I don't see what a portal's mass has to do with either of my two original claims.

>>377776028
B-fags need to die. There's no medium for energy to transfer from portal to box, so B is impossible.

>There's no medium for energy to transfer from portal to box
Not even remotely true. There actually needs to be, for the situation to make any sense whatsoever. That 'medium' is the gravitational field; you know, the thing through which the portal and the object interact in order to teleport the object in the first place.

Consider a fluid traveling through the portal with some flux, and out with the same. If it does not maintain momentum, an infinitely thin section of it would pile up at the interface until pressure forces it out. This would look like an infinitely thin pressure wave in the fluid, which otherwise flows out as quickly as it flows in. For any solid object, the exact same logic applies: If any object can pass through a portal without immediately exploding at the interface, momentum in relative to the entrance portal must be the same as momentum out relative to the exit portal. The change in energy is taken on by the portal through their interaction, just as the change in an object's momentum must be taken on by stationary portals.

>>377789930
What's with B-fags and not understanding the hula hoop analogy. Portals bend timespace. There's no medium for the portal to transfer energy to the cube. None. They don't interact in any way other than whatever mass the portal has and therefore gravity, and either that's 0, and we're still at A, or infinite, at which point the cube wouldn't be stationary on the platform anyway.

>>377789725
I don't know what you're getting at. If you move the blue portal, relative momentum of it relative to chell is constant, as is the relative momentum of the orange relative to chell's arm, which is identical. It doesn't get pulled apart.

Thanks for linking to what proves you wrong. In wormhole theory, when your frame of reference is so that the wormhole moves and the cube is stationary, the cube doesn't magically gain momentum in the same frame of reference once it exits the other side. If you had taken a single day of physics in high school, you'd know this.

>The curvature of spacetime = gravitational field (no s)
No, the curvature of spacetime is a result of gravity. Or the cause of it, depending on your interpretation. Regardless, they're not the same.

>>377790118
You didn't address that assumption though
Imagine the portal coming towards you very slowly, does your hand exit the orange portal in similarly slow fashion then?
How about the blue portal approaching very fast? Does you hand exit the orange portal very fast?
If the speed of the portal moving affects the exit speed of the hand, by choosing different origin for the coordinate system you get a situation where the portal stays in place and whatever enters moves fast.

>>377789379
I fail to see how conservation of energy would imply that, dude. If you want to make a case for it instead of spouting those three words, knock yourself out.

>>377789426
You do understand that in a frame of reference that isn't stationary w.r.t. the lab's frame, the portals would be moving, right? The idea that portals can't move implies that any frame in which portals are moving is "wrong".

Btw since in-game, you can place portals that are immobile in the laboratory's frame of reference, and the lab's frame isn't an inertial frame of reference but a rotating frame of reference (since it's standing on the earth), this means in-game portals are moving no matter the inertial frame you take.

You can even add the fact that you can put an blue portal on earth and an orange portal on the moon to fully refute your claim, since then even in the laboratory's frame, the moon portal is moving.

>>377790435
>Imagine the portal coming towards you very slowly, does your hand exit the orange portal in similarly slow fashion then?
Yes.
>How about the blue portal approaching very fast? Does you hand exit the orange portal very fast?
Yes.
>If the speed of the portal moving affects the exit speed of the hand, by choosing different origin for the coordinate system you get a situation where the portal stays in place and whatever enters moves fast.
Yes.

What you're not getting is that something can move fast in your frame of reference while having literally 0 energy whatsoever. Sure, the hand shoots out of the portal, but that's not because the arm is moving, or because it has any energy at all. It's because the space AROUND the arm is moving, and the energy that moves the space has no consequential means to influence the energy of the arm without being in direct contact with it, which it isn't in this situation.

>>377790118
>Portals bend timespace. There's no medium for the portal to transfer energy to the cube. None.

Seriously, do you also believe in the Aether or something? Do you not understand how moving an object through curved spacetime is an interaction? It's like your trying to apply Newtonian physics directly.

Tell you what, riddle me this: when an object goes through a stationary portal and comes out another stationary portal, it comes out with a different momentum than when it went in. By your logic, this is this in violation of conservation of momentum, which is equivalent to a violation of energy by special relativity (it's a blatant violation of conservation of energy in a different inertial reference frame). So either you immediately must throw out any argument via conservation of energy, OR you must concede that there is an interaction between the portal and the object through which momentum and energy transfer can occur (which should be obvious).

>>377790390
>Thanks for linking to what proves you wrong. In wormhole theory, when your frame of reference is so that the wormhole moves and the cube is stationary, the cube doesn't magically gain momentum in the same frame of reference once it exits the other side.

If the wormhole's ends have different velocities, yes it would. Assuming it was even stable, and would remain stable if you tried to send anything through it, which is almost certainly not possible, but that's besides the point.
>If you had taken a single day of physics in high school, you'd know this.
Interesting that you mention this, since I just finished my undergrad in physics.

Imagine watching the cube exit the blue portal in slow motion, frame by frame. In each frame, the amount of the cube exiting the blue portal must be equal to the amount entering the orange portal, by conservation of mass. By induction, we can sum this fact up over the entire cube to prove that it always exits the blue portal at the same speed it enters the orange portal. By conservation of momentum, situation B must occur.

>>377791289

the movement of a portal would cause a type of friction where the connection sections of the universe smash into each other.

>datamining the average /v/irgin's lack of understanding of physics
Okay anon

>>377791327
The portal can't move.

You can't actually use the laws of conservation of energy or momentum to argue for A because portals violate both laws.

You can use a portal to move from a lower location to a higher location. When you come out of the higher portal, you have gained energy due to the extra potential energy of being in a higher location. Thus, portals do not obey the law of conservation of energy.

Second, in the Portal games, when you go through a portal, you come out the other side moving at the same speed you entered, but in the direction the exit portal is facing, which may be in a completely different direction than the entrance portal. Since momentum includes direction, if a portal changes the direction you are moving in, it has changed your momentum. Regardless of what the game narration claims, what portals actually conserve is speed relative to the entrance portal.

In the games, if you put both portals on the floor and then jump into one of them from a great height, your momentum when you come out the other one is completely different from when you went in, because you're moving in the opposite direction. Thus, portals do not obey the law of conservation of momentum.

A.

Imagine a flower vase on a table cloth that is being quickly pulled from underneath. The cube is the vase and the tablecloth is the portal in motion. From the tablecloth's perspective it would appear as if the vase is moving off it really fast, but no, as soon as the tablecloth has been pulled completely the vase will remain still.

I'm a physicist, I can answer this question.

a) momentum is relative, wether the orange portal moves down or the cube moves up into a stationary portal doesn't matter
b) all of physics is reversable, the reverse movement (cube moving into the blue portal instead) must recreate the momentum of the orange portal side, as dictated right now

this means: no matter what happens on the blue side, if you do the opposite, the cube and the orange portal must have momentum with respect to their reference frames

but wait a minute, this is just B) in reverse, so you can now transpose the whole situation and determine that the only viable answer is B).

It is B) because reversing the operation must have the net opposite result, since A) dictates that no momentum transfer happens (it just plops out), this would mean that if A) were true, just gently putting A into the blue portal would make it shoot out of the other side at high speed (or shove the portal away, but that's the same for the sake of the proof). Since this would violate the entire premise of A), A) cannot possibly be true.

So there is one proof by negation and one proof by induction that B) must be true in both cases.

It's B).

issue with this is that if you move the portal the box beyond the portal is moving while in the same space as you it remains stationary so its a paradox. You'd need an infinite amount of energy to move the whole universe's mass when moving the portal.

>>377776848
see>>377798141

the portal doesn't need to move to recreate the situation

there is no absolute frame of reference

it's still B

>>377799092
Except that's wrong you retard.

Are you retarded?

>>377799092
And here we see how bfags know fuck all about what they're talking about. I wish it was rule that if you are a bfag, you must timestamp you supposed degree

>>377777777

>>377799186
Okay, you're no physics person that's okay, but surely the concept of relativity is something you atleast know about?

Basically there are is no absolute movement in the universe. Wether you are moving towards an object or the object is moving towards you literally has no difference. Any physics phenomena follows the concept of relativity, from momentum, to fields, even shit like electromagnetism.

So by that itself, even if portals have infinite energy and mass, you can still recreate the problem as defined, because only relative motion matters.

Wether the portal moves towards the object or the object moves towards the portal doesn't matter, it's all the same.

Note that while an object with infinite mass cannot be accelerated, it can still be moving with respect to different reference frames, so this whole situation is still valid.

Ignoring for a moment that an object with infinite mass would be a universe sized black hole, this means that none about the problem is invalidated and none of the post I addressed above matters. It makes no difference.

This is also your most intuitive answer right there, since moving the portal and moving the object is the same thing, and the second alternative happens all the time in the game, you have your answer right there.

I'll draw up a picture in a second.

>>377799554
See >>377788529
The problem is literally paradoxical.

>alets and blets

>>377789725
Chell never enters or exits a moving portal, for one.

But for another, you don't actually feel any acceleration as your relative speed remains constant. Unless the portal actually accelerates or decelerates before you're fully through.

>>377789356
So wait, in this scenario, the car (with you on it) is moving at 100mph and suddenly comes to an immediate stop? And you're saying you wouldn't go flying at 100mph?

>>377776028
A if the portal acts as a window.

B if the portal dematerialises incoming objects and rematerialises them at the opposite portal in the manner with which they entered the portal.

>>377800016
Nah, it's actually just B.

>>377801308
Other way around, actually.

neither.

you can't move a piston with a portal on it.

sit down pup

>>377779959
Except the actual cube is static. 0 velocity, 0 acceleration.

>>377804498
Doesn't matter m8. It's the same thing.

You know for how much Afags like to say it's a hula hoop/doorway/hole/whatever, you seem to have real trouble actually envisioning them that way. Something cannot go out a doorway faster or slower than it went in, because it's the same motion. You're too hung up the cube "standing still" but it's all relative. Portals create two frames of reference, and portals obviously impart motion as well, for that matter. Just imagine what would happen when a portal begins to move when something is still suspended inside.

>>377804476
Literally don't give a fuck if it's a or b. All I know is that portals can't exist IRL, therefore, debate is pointless. So now I'm gonna bust your balls until you prove to me that you're an actual, credible source.

So that's a no, then? Looks like B stands undefeated.

How these threads STILL get hundreds of replies every time amazes me...

The answer is A. The cube does not move, the portal moves around it. The cube is not traveling from A-B, A-B are being warped and traveling around the cube. That's how wormholes work, which is what portals are.

Here, lets reverse this situation.

What happens now?

>a medabots thread gets moved to /m/ and inevitably dies
>these maymay threads almost never get deleted
choke on a fucking cock, mods.

What the fuck are you fags arguing about? the cube doesnt even move, it doesnt travel through the portal, its on the first platform all the time, only that when it crosses the portal it's suddendly upside down.

>>377807592
Wrong. The portal never moves.

>>377807424
Are you... catapulting it into the portal at the speed of the piston?

>>377807671
It does in this hypothetical situation you massive fag.

>>377807592
>it doesnt travel through the portal
>when it crosses the portal

Also why would it be upside down?

>>377807739
Except it cant you faggot.

>>377807748
Not upside down, my bad, just a bit tilted, the only thing that changes about the cube is the direction of the gravity as seen in my shit drawing.

>>377808049
What's Ѭ again?

>>377808126
Yeah, exactly. Nothing changes. It was already moving relative to the portal, and it keeps moving.

>>377808258
The portal has infinite mass and the piston is unable to move down.

>afags
>dude hula hoops lmao
>bfags
>dude relativity lmao

>>377807680
A cannon ball is shot into the blue portal.

A.The cannon ball bounces back off of the platform on the other side of the portal, since portals are a shortcut in space.

B.The cannon ball somehow transfers its momentum to the portal, which in turn transfers its momentum to the piston, causing the piston to shoot back with the speed that is fell down in the OP. And the cannon ball will lose all of its momentum and becomes stationary on the platform.

-----------

Same things should happen in reverse if the situation is reversed, right.

>>377808320
Okay but like

What if it could

I mean portals can't exist anyway

>>377808818
Interesting problem.

I think it might actually be B, given that we already know that portals transfer momentum.

>>377808847
>being a Cfag

>>377809262
We did after all see a moving portal in Portal 2

>>377809449
A non-interactable moving portal.

>>377776028
>A

The cube has no momentum and wouldn't spontaneously accelerate

>>377808126
Probably the best answer I've seen

>>377809127
the cube has no momentum

>>377809862
From one perspective it obviously does.

Anyway that wasn't what we were talking about.

>>377809606
Common misconception. The cube doesn't actually accelerate, it just maintains its relative speed.

>muh hula hoops
Afags.

>>377776334
True webm

If there was one of those prosthetic ass/pussy things and you put your dick in the ass part and there was a portal in the asshole and it came out in a dude's ass would it be gay?

a. no
b. yes

>>377808818

You didn't reverse the situation properly. In the first scenario, the orange piston has a downward force acting on it. In your scenario, you forgot to include the, now reversed, upward force. The orange piston wouldn't shoot back up because of the ball, the orange piston would shoot back up because of the upward force you forgot to include.
