Thread 714229946

How do you solve this???

>>714229946 (OP)
By being intelligent and realizing it has to be B to preserve relative velocities between the cube and the portals.

>>714230142
through what mechanism is momentum being imparted on the cube in b

>>714230335
Until Valve releases Portal 3

It's A, anyone who thinks otherwise is a retard.

Instead of pushing it all the way, imagine stopping midway. By tard logic it would split in half, by anti-tard logic nothing will happen.

>No you are tard, ofc it would split.

Then by this logic the portal applies the force the moment it stops. Which means it applies the force in 0 meters, requiring infinite force and destroying the fucking object.

This also means that any fucking fluctuation in the portal movement will obliterate the object.

Fucking uneducated retards.

>>714232469
>By tard logic it would split in half
>he says being a complete tard thinking that tugging on one end suddenly makes a solid metal cube into sheet paper
>>714232469
>Then by this logic the portal applies the force the moment it stops
No, it the portal applies momentum to whatever passes through it, stopping and starting is irrelevant

>>714232469
>the moment it stops
>infinite force
Show me anything that can stop in 0 time.

>>714232807
>No, it the portal applies momentum to whatever passes through it, stopping and starting is irrelevant

So it must apply a force at that border. And it has to be infinite. Do you know anything about momentum other than:

>Speedy thing goes in, speedy thing goes out.

You cannot apply a force in an instant. It has to be applied for a duration. By applying a force in a arbitrary border, you are saying that you apply infinite force in 0 seconds.

>he says being a complete tard thinking that tugging on one end suddenly makes a solid metal cube into sheet paper

Infinite force will split it.

>>714233483
>Show me anything that can stop in 0 time.

You can model real life physics with discrete time intervals. Real life physics behave same (even more accurate) if you reduce this time step width. And this means that as we use smaller and smaller time steps to model this bullshit (getting more accurate real life physics) the tard option will require force that is blowing to infinity.

Have you taken a fucking path integral in your fucking lives.

>>714233837
Approaching, but never reaching, zero.
Even concrete bends.

>>714234043
The force is never infinite, just couple gorrilions what will break the concrete.

And again, this logic says that if we stop it midway (and the object is indestructible) the parts that passed the portal will pull the object.

>>714236979
That's some strong glue

>>714229946 (OP)
This was already solved.

Bfags, your response?

>>714230142
glados, send this nigga to the retard exploding chamber.

Again the answer is whatever would make a puzzle more fun. Which would probably be B because launching a cube would be more interesting than having one plop out.

>>714232807
no, the portal doesn't apply momentum you dolt. objects with momentum going through the portal carry it our the other side. it's why if you drop 100 feet into a portal, you will go flying out the other one, and not just flop on the other side. because YOU (the object) have the momentum, not the portal.

>>71423917
wait until this dude figures out you can launch a cube by following the basic rules of physics, IE dropping it down a hole with a portal at the bottom so gravity launches it out of the other portal.

>>714239860
OR, even better: having the platform that the cube is resting on slamming up into the portal platform would actually launch the cube.

>>714232469
it wouldn't split it half it would go flying but only with half the force it would if the portal entirely covered it. the momentum of the half that went through would carry the stationary half with it

Portals dissapear when the platform moves fordwards/backwards.

>>714240205
again, portals do not carry momentum. objects going into portals retain their momentum until acted upon by an outside force like gravity. me slamming a ring down around you at 100mph does not mean you were going 100mph through the ring.

>>714240363
not true. you use them to cut the tubes to the gas generator by putting them on moving platforms.

/thread

>>714240476
Those are moving downwards/upwards.
Learn to 3d movement.
Cmon, go play the game again and test it yourself, there is several parts in the game in wich the platforms moves fordwards/backwards and the portals just dissapear.

>>714238949
where did all the energy from the relative momentum go?

>>714240392
>me slamming a ring down around you at 100mph does not mean you were going 100mph through the ring
But it does. It literally does.

>>714240571
>implying the portal that OP posted ISN'T going downward

And they also disappear on other sideways moving platforms in the game too, as well as rotating/tilting platforms.

>>714240392
yes it does moron.
to move through something you need to be moving relative to it.

>>714236979
This just proves A. Notice cube doesn't fly off when you stopped the platform.

>>714240205
Half of the momentum, not force. That is the issue, required force is applied in 0 seconds (so infinite force).

>>714236979
The problem is that A-friends can't understand why this is a problem.

>>714240795
Movement is relative to the portal not to the viewer anon, learn to 3d movement.

>>714240728
it had no relative momentum. if you notice, the cube was just sitting there?

>>714240729
you are literally sub-60

>>714240728
Into the platform on which the cube sits.

>>714240856
>>714240946
except the whole world was moving with the portal.
where did the energy go and why did the cube suddenly stop
are you trying to say that the whole world stopping suddenly makes more sense than cube continuing to move relative to the world, like it needs to be doing in order to pass through the portal?

>>714240392
Even in A, objects do not retain their momentum, because they can change direction. Momentum is a vector. You might be trying to say they should retain their kinetic energy...?

>>714240809
notice how you standing still involves you not moving? If i slam a ring around you, you didn't move through the ring. the ring moved around you. Just like how if you walk through a stationary doorway, the doorway doesn't move around you.

>>714240728
>Relative momentum
Lol.

>>714240830
Because it is the only logically consistent scenario.

>>714238949
I love the added explosion effect that rockets out of the orange portal and suddenly disappears. What would happen if the sparks didn't disappear, I wonder? They'd just fall to the floor too I suppose.

>>714241057
well if you wanna go that route then the cube would have infinite energy, as like you said the WORLD is moving into the cube which would launch it much further than what B proscribes. But most of us choose A because portals violate energy laws regardless and any thought exercise should focus solely on classical physics.

>>714241057
what does the world moving have anything to do with it. if you did this experiment in a vacuum in space in some pocket realm where nothing but the portal platform moved and the cube only had basic physics like 1G of downward force, the result would be the same.

>>714241194
That's clearly just a visual effect for emphasis. It's not supposed to represent a physical thing popping out of the slanted portal.

>>714241312
I understand that, what I'm saying is that it's an unnecessary flourish that completely diminishes the point the gif is trying to make.

>>714240852
what you MEAN to say is that portals do not travel on their Z axis. learn XYZ coordinates, FAGGOT

>>714229946 (OP)
gamedesign wise B because A is boring
consistency wise A as this soulless AI pointed out >>714238756
theoretical physics wise im pretty sure its the hidden third option C where the cube is squished or melted by the universe bending pressure of a moving portal.

A isn't even well-defined. If I gently push a cube through and it "plops" out, what is its PRECISE trajectory? There is no way to answer that question. It's nonsensical.

B isn't perfect either, although it could possibly be fixed by imparting some energy/momentum to the portal object to enforce conservation. Even then I'm not sure what happens with gravity. But at least it's clear what happens in B, physically speaking, even if it's "unphysical" because it doesn't conserve energy. Note that A doesn't conserve momentum either, since momentum is a vector and portals can change orientation.

>>714241307
I am not sure that they violate the energy laws. I feel they need gorillion of watts to keep open.

>Infinite falling.

Yeah but if:
energy_for_portal > potential_energy_gained_by_teleportation

I think I should be okay, no?

>>714241183
How is it logical for an unfastened cube to stay on a platform moving around like that?

>>714241516
Using /3/ jargon doesn't discredit what I said, but thanks for your specific insight anon.

>>714241651
>jargon
nigga it is literally BASIC 3D GEOMETRY. you should have learned this shit BEFORE HIGHSCHOOL.

>>714230746
conservation of momentum
cube goes through portal at x velocity = cube exits portal at x velocity
that velocity is then maintained

>>714229946 (OP)
i remember this meme like 15 years ago and arguing with retards on /sci/ who thought the answer is B

its always been A, anyone who says otherwise is actually dunb

question for Afags
If a portal were free-falling through the air at terminal velocity, would there be a gust of wind coming out the other portal?

>>714241930
>cube goes through portal
Other way around. It's the portal going through the cube. The cube is sitting still on the platform throughout the entirety of this. It's the portal that is moving, and its velocity is halted by slamming into the platform on which the cube sits.

>>714242094
yes, but then if after all of that falling it landed on a cube or soccer ball, the ball wouldn't suddenly fly at you at terminal velocity, it would just plop out

>>714240363
/thread every thread.
but fags will keep discussing about anything.

>>714242243
easy to patch out with cheat engine though so it's not an argument

>>714242094
No. Only thing changes for us, is how fast the air molecules pass the portal, their momentum does not change.

Try to understand my analysis monke,

>>714232469
>>714233837

>>714242175
>It's the portal going through the cube
That would still have the same effect you dolt - the cube would still be moving (defined as a change of position over a period of time, because Afags always jump hoops around the definition of movement) at the rate the portal envelops it
There would be nothing from stopping the cube from continuing the momentum from that movement
>>714242205
How could it create a gust of wind if the entering matter doesn't exit the portal at the same velocity?

>>714242306
No shit but still not canon

>>714230260
If those were actually portals, yes. It would work that way.

Tell me. Afags. When the orange portal is moving, what do you suppose is happening to the air that's passing through it? Is it all stacking up and compressing in a thin disc on the other side? Or is it flowing out of the blue portal like a jet?

Why wouldn't that continue happening to the cube? The cube would appear to be moving from the frame of reference of the blue portal. Why would it suddenly lose all of that inertia at the last second. Even if all the orange portal's kinetic energy is arrested on contact with the surface the cube is sitting on, why would the rest of the cube which is in motion not drag the last sliver along with it?

>>714242078
In the .gif, the observer is stationary. What a retarded analogy.

Abros....... our response??

momentum is gained by force
force is mass and acceleration
the cube has mass
the cube has acceleration
where is the flaw? "nuh uh it's just sitting there." not on the exit side, then it's moving. it was sitting still before entering, that's in the past

and before somebody who didn't play the game says this pic isn't how it works, this is literally how you destroy the neurotoxin plant

>>714242924
In my analogy I is told in the eyes of the moving portal. I am not surprise it flew over your head.

Coding bias to obey their tard belief. Any game engine is not a viable proof for A or B.

>>714243108
HAHAHA faggot. In this portal itself has speed. This is not A or B.

Dont worry Abros - I have zero velocity or momentum going through the portal, so I'll be fine.

there has still yet to be a SINGLE refutation of this
not one. nada. nothing. zilch

i think Afags can only think in the binary of before and after the piston slams down, and can't visualize what happens AS it slams down
I doubt they can rotate 3d geometry in their heads either

>>714242738
C. The box doesn't fly out like in B but it does push the ball away unlike in A

>>714242738
How does it move the ball at all if it has no force or momentum?

>>714243140
In that case it's more like:
>have a popsicle stick in your mouth

>move head to the right
>box moves with you
>stop moving your head
>box flies off stick to the right
>WTF.jpeg
>It wasn't moving I swear, why didn't it stay on the stick?

>>714243752
That's not how it works in the portal universe though.

>>714243249
Left:
1. Useless refutation.
2. Lol B tards using fancy words they don't understand. At this point we should model gravitational wave propagation and time dilation. And no, still B's are tards.
3. What the fuck is this flatearther math.
4. You didn't understand the portal stops halfway argument. It implies the object will be cut in half. Because it means that the required force has to be applied in near zero time.

Right:
1. Wormhole/window does not change it fucking retards. Again using worlds you don't fucking understand. Are you the same faggots that propose spooky action means teleportation or telepathy?
2. See >>714242078
3. This is nice actually. But depends on the car's velocity. The cube will exit with its speed so if the car is faster it will thrown back.
4. Same fucking retarded argument of left 2.

these threads are never about portal universe (in-game) physics
it's just retards waxing theoretical physics

>>714244108
>Wormhole/window does not change it fucking retards
When was the last time one side of a window moved while the other side stayed stationary

>>714229946 (OP)
If B were correct then chell would be flung sideways on the moon because it moves with the speed of 1 kilometer per second relative to the earth

>>714244108
>this entire post
Useless refutation.

>>714243586
Besides that the moon n planet are not simulations ingame moving at the incredible speed they are irl and that in the original op pic A is what happens ingame?

>>714242362
What if there was a stationary pole (not fixed/bolted to the ground) balancing upright. The portal comes rushing down from the ceiling but suddenly halts halfway down the pole. By your theory, the half that went through the portal now has massive momentum upwards - so you'd see the pole actually get sucked up into the portal even though the portal stopped moving? Seems weird to me.

>>714243586
OHNONONONO

>>714244451
>By your theory, the half that went through the portal now has massive momentum upwards
Correct - one side of the portal is not only moving out at a fast speed, but also now has gravity working on it which would cause it to shift on both ends
It seems weird because portals are fictitious and would completely break the laws of the universe if they existed

>>714243338
Interesting how you manupulate gravity to apply from right when the platform stops. Nice try. These simulations mean nothing for both sides.

>>714244359
chell looks like THAT!?

>>714244595
>Interesting how you manupulate gravity to apply from right when the platform stops
Why wouldn't it apply, ESL-kun?

>>714238949
Change the perspective to the other portal. Whoops, now the two scenarios aren't consistent! Only when both perspectives are consistent will you have the correct answer.

>>714244402
according to the fact core the moon moves

>>714244592
>portals are fictitious and would completely break the laws of the universe if they existed
You're right lol. Why is this a recurring debate on /v/ then? It's nonsensical because there's no right answer. It's some "waiting for Godot" stuff.

>Bfag thrusts dick into the portal then stops.
>Bfags dick tears off and flies into the distance.
and that is why A is correct.

>>714243586
Game logic does not matter. It is A. The momentum vector's norm will stay the same. Due to angular movement difference between orange and blue it's angle might change slightly.

>>714244882
>Why is this a recurring debate on /v/ then?
/v/ is full of two things - midwits who like to show off their intellectual prowess on this absolute trash heap of a board, and people who know how to attract easy bait

For fuck sake.

>>714245217
That's not an actual argument for why gravity WOULDN'T act on the side of the cube that had exited the portal
in fact gravity working on the cube beyond the portal is one of few things A and B are in agreement on

>>714243752
You say all that shit that but forgot to look left where the cube is in fact stationary.
But grog saw movement stuck in his simple flesh ball perceived perspective so it's moving even though it's not.

>>714245354
>afags arguing that an object changing position over time is actually still stationary
a tale as old as time

I was a long time A fag until I realized that the game consistently demonstrates momentum being conserved only from the portal's point of view.

>>714245304
That is what I am saying. It doesn't apply correctly in this. Or maybe it's set too low to see. Seems like it doesn't apply force based on the mass passed through the portal.

Also, the fucked up thing is, the gravitational waves should travel through the portals if they are wormholes and that complicates everything.

>>714230253
well alright then

Remember, Anyone who supports b is trolling or is so unbelievably stupid they fell for a troll so hard they now believe it.

>>714245361
Yes A. But cube is lost inside the wormhole.

>>714232469
How the fuck would a stationary object remain stationary while going through a stationary portal? On some level there has to be momentum imparted upon the cube or else you just crush the cube flat and A is completely impossible.

>>714245789
show me a portal irl
you can't? then your argument is worthless

>>714245729
Damn... I never thought of it that way... you've opened my eyes... Afags I kneel...

>>714229946 (OP)
It's B or C (where the cube just gets squashed).

Consider what happens moment-to-moment as the portal moves over the cube.

The portal moves over the first layer of atoms. The first layer is now immediately on other other side of the portal.

The portal moves over the second layer of atoms. The second layer is now immediately on the other side of the portal. But wait, there's already something there. So the first layer gets shoved out of the way since the second layer has the rest of the cube and the platform under it (with a bit of resistance due to inertia). Repeat for the rest of the mass.

At the end of the object, it would either get flattened if it wasn't structurally sound enough, or it would have momentum from every layer of particles being forcefully moved repeatedly in a short period of time.

>>714245435
Because despite caveman "what monkey see = all there is to it" retardation it's quite literally the portal that is moving.

>>714245832
Imagine you have foreskin. And that is the wormhole. You pull back the wormhole (your foreskin) and tiny dick appears out of nowhere. No matter how hard you pull that skin, the tiny dick will not move, but will be revealed faster.

>>714246025
>it's quite literally the portal that is moving
So how is the cube reaching the other side of the portal while remaining stationary

>>714245903
My argument that the game is not a simulation is not true because portals aren't real? Are you feeling OK?

Okay B faggots thanks for being faggots and making me think. It was fun. Love you regardless (except the pedo ones).

godspeed a-utist
may we argue over inane bullshit again in the future

>>714246076
Perspective. If we replace cube with you it wouldn't seem like you are moving.
Kind of like how you're flying tens of miles/kilometers per second right now but can't perceive it from your perspective but looking from space you from a 3rd perspective you can.

>>714246682
That's fucking retarded - if your position is changing over a period of time you are, by definition, moving.
See >>714245435
>If we replace cube with you it wouldn't seem like you are moving
Yes it would - once the portal passes over you you would feel gravity forcing down your body in two separate directions, as the space between your feet and the descending portal quickly lessens.
By the end it'd feel as if you're being lifted up on a platform

>>714241307
no it wouldn't, a cube is small and has little mass, compared to the whole fuckin universe, which you need to be moving in order to move the portal
most of you choose A because you don't understand what you've been doing throughout 2 games and what has been explained in the first 5 minutes of the game.

>>714241310
yes the result would be the same in any conditions, and the result would be B.

>>714241151
to pass through the ring there needs to be movement.
there is no absolute frame of reference, only relative ones.
were not standing still, were on a spinning ball, which in turns spins around the star, which spirals in a galaxy, which is moving away from the center of origin.

>>714246358
The game cannot even simulate the ball you're standing on right now but you think because it's idea of an imaginary function (portals) fits your idea then it's a simulation of real life physics when it's literally not. It's a game need I remind you in which you can fall without fall dmg but hey celestial bodies must be true to life simulations? Lol

>>714242078
but it did fly to the left. relative to your head.
and to stop that momentum you had to apply opposite force to counteract the inertia.

same with the cube. nothing is applying the opposite force so it flies out and slows down according to gravity and air resistance.

>>714246682
>If we replace cube with you it wouldn't seem like you are moving.
Yes it would? Imagine yourself emerging from the blue portal as the cube does - how is that not moving?

>>714247017
A lot of retards fail to understand this simple fact

>>714229946 (OP)
You don't, because this violates the laws of nature. Time travel and portals are not possible.

>>714245484
I feel like the biggest thing causing people to think it's A instead of B is that they think the cube is too heavy to go flying, so plopping is more intuitive. Everything else is just them justifying it.

>>714248139
but it doesn't matter how heavy it is it would be B regardless of the mass

>>714248137
fucking KEK

>>714247159
Looks like it yeah but you going to feel a tug away from where you're standing? What about eyes closed?

>>714242738
A. Objects cannot move through a mobile portal according to the physics of the game.

>>714248356
>but you going to feel a tug away from where you're standing?
You're going to feel the force of motion and gravity act on you as you move through the portal, yes
How is this even a fucking question

>>714243752
What about the Orange portal's deceleration?

>>714248543
It doesnt decelerate until its completely hit the platform the cube is on, by which point 99.999% of the cube is through the portal so any additional mass on the other side is negligible

>>714248435
>Objects cannot move through a mobile portal according to the physics of the game.
The second game depicts two instances of moving portals (the one you cut the neurotoxin pipes with and the one on the moon). That the coding for making these work with the existing mechanic doesn't change that they are depicted as working within the universe of the game.

>>714248918
The game has an object leaving a mobile portal, not entering one. The only rule broken is that the portal doesn't vanish when moved relative to the second portal

>>714248656
That deceleration is equivalent to the entire universe coming to a complete stop. The momentum of such an event would shear the backside of the cube off if the portal applied momentum to the dune.

>>714248519
Like you feel the 30km per second were moving at now?

>>714244076
Elaborate.

>>714249429
The deceleration only applies to matter going between the portals, retard-kun
>>714249559
If the earth suddenly began spinning 10x faster I could imagine that being felt
Similarly, going from stationary to feeling your body move through a portal at 100miles per second would absolutely be felt

>>714248289
Exactly. It would be B regardless. But that's not intuitive to them.

Physicist here, you're all retarded and getting trolled.
The actual answer is: neither

My theory is they put themselves in the place of the cube and conclude that it doesn't experience acceleration. That part is correct. But then they conflate the portal stopping with the falling room stopping, which isn't the case, because when the portal stops, the cube is already past it and can't be affected by it.
So from the cube's point of view, the room just keeps falling, the floor escapes from under it, then the cube is pulled towards one of the walls (which is actually the floor), following the new gravity it found itself in.

These threads always amuse me greatly but I kinda feel bad for the pseuds that fall for the trolling and end up actually believing in B

>cube goes through portal
>Other way around. It's the portal going through the cube.
Literally the same thing.

Literally the opposite. Being "flung sideways" would be Chell's motion not changing.

my thoughts exactly, though i don't understand why

It's clearly B. I don't need math, or arguments, I just need a working brian. If you don't agree, kill yourself.

The 4th dimensional portals aren't moving in the 4th dimension

Kek'd at this.

How about poop portal? Will poo fall into loo or just float under portal?

B fags poop standing up

It should be B, but it's actually A when using the portal gun because le wacky Cave Johnson made physics work wrong.

This isn't a gotcha. The speed at which the stick figure is ejected from the Moon isn't related to the Moon's rotational velocity. The reason Chell was flung from the Moon's surface at the end of Portal 2 wasn't because she was acted on by the greater relative velocity of the Moon, it's because the Moon has no atmosphere, unlike the Earth. Opening a portal to the Moon causes a pressure differential between the relatively high-pressure air on Earth and the pressureless vacuum of the Moon, violently sucking air out in an attempt to even out the pressure. It's like opening the airlock doors on a spaceship.
