Thread 720155496

Afags truly are a bunch of retarded specimens

OP reversed it

From here on, all posts refer to A as flopping out, and B it flies out.

Ending proves B

Now I'm confused but I'll believe OP.
Anyways idk why Afags would be retarded that one makes the most sense to me

>>720155765
This is a fucking scripted event to fulfill a narrative role ffs how many times do we have to go over this.
Nothing in the game shows that it would ever work like that in the hypothetical scenario of the game.

>>720155932
Scripted events in all videogames supersede gameplay in lore and story. Doesn't matter if you can one shot the boss in gameplay, the scripted event will have them laughing at you and running away. That's what happened.

Surely no one would pick B, right?

>>720155496 (OP)
i dont understand, why are these threads allowed? all it is is a bunch of trolling and physics midwits arguing. its only VAGUELY based on a CONCEPT in a video game, and nothing else. its incredibly off topic, and nothing more than trolling and arguing.

>>720155496 (OP)
>>720155765
Doesn’t the ending prove A, since 2,288 mph is way faster all the things flying out?

>>720156181
>Redditor programs physics wrong
I'm supposed to be impressed by this?

B. The box has only gravity applied to it, it appears out of the portal with a speed of 0 and then falls down.

If you reverse the experiment and have the box traveling upwards through the portal the answer would be A.

>>720156181
Whoever wrote this adds a lot of unnecessary information and also made mistakes. The speed of the orange portal is irrelevant for the question, there is no situation where the top of the cube would tug the bottom half with the portal moving at a constant velocity, and the transition does not take place over a nonzero amount of time. It looks like something that was intentionally written to create conflict rather than to answer the question, especially when you didn't even attempt to prove the source.

>>720157549
I got it from a reddit post that I believe used to link to Steam Forums.

>>720157949
Unironically yes. It changes location without moving. That's what portals do.

>>720157825
The physics falls apart when you consider >>720156726

>>720156726
It is B though

>>720158047
So you're saying it changes position over time without moving?

>>720157268
>>720157856
Nope. Here is the explanation. Also consider moving back into the portal.

Shut the fuck up you annoying twat and go back to your 5925th gacha thread

>>720157825
So the same guy from this really old email. He actually discusses some similar things here. He still makes the mistake that the acceleration might happen over time, which is clearly proven wrong by the moon scene. However, he does get it right that the bottom would push the top up in that scenario where the cube would be accelerated rather than the top pulling the bottom up. He kind of just ramble ideas in both explanations and comes to the same basic conclusion for the same reasons, so it seems reasonable it could be the same person that just forgot they had already responded to this and is not aware of the problems that could come from just throwing out ideas.

>>720158436
>inb4 a retarded afag ignores the reverse where she is pulled back through the portal against the air pressure

>>720157949
The portal envelops the box at X speed and the platform hits the box platform at X speed where speed is reduced to 0 as the 2 solid objects cannot pass each other, the speed is cancelled out. There is no other force applied to the box than gravity and the resistance of the platform it stands on.

During the portal enveloping the box, it has an alternative gravitational influence at the other side but it is proportional to the amount of mass that has been sent through, which will only reach 100% once the 2 platforms meet and cancel out speed. You can't have 99% of the box fly out the other side quickly while there is still 1% of the box stationary.

>>720158149
No it's not
That's like saying if you tilt the portal on its side and move it upwards at the speed to counteract gravity the water wouldn't flow out at all

you guys legit think that an object moving through a portal is gonna magically plop out of it with no speed? i know this is /v/ but are you that schizophrenic?

>>720158947
You know, NPCs who can't even imagine an apple, 80 IQ niggers who don't know how they would feel if they haven't had breakfast... plently of Atard material out there.

>>720158787
But does it cancel out the box's rotational velocidensity?

>>720158240
You understand this is an argument for A right?
You don't shoot out into earth going the speed of the moon. You *plop* right on back

>>720158947
Items sent through portals in the games were moving, they had inertia and momentum and acceleration and velocity, etc.

The item in this experiment has gravity as 0 and upward resistance as 0. It isn't moving through the environment so it can't suddenly have any of those forces applied to it.

>Game says that something with velocity will maintain it going through a portal
>Game also says that portals can't exist on moving surfaces
>These are both true through the entire series
This entire "problem" you morons keep arguing over can't even happen in the first place.

>>720159409
>he thinks portals are real
Nice try, loser.

>>720156726
If the piss didn't inherit the blue portal's velocity as it leaves the particles would be spread thinner and thinner depending on how fast the blue portal is moving. Moving fast enough and the piss would actually come out as a mist. Think about it. If the blue portal was moving a kilometre a second then you'd be seeing one second's worth of the piss being poured out stretched over that entire kilometre.

Now imagine yourself exiting the portal in that manner. You to you be scattered over that kilometre, same as the piss.

>>720159253
>You don't shoot out into earth going the speed of the moon. You *plop* right on back
Yes anon, you return to be moving with the eath when coming out the other side.

Your speed gets changed going from earth to moon. Demonstrating B.

Your speed gets changed again going from moon to earth. Also demonstrating B.

>>720159409
The first line is literally contradicted by how the portals are shown to work.

Portal flings are literally using portals to change your velocity.

The A outcome in pic related is what would happen if your velocity was actually maintained. Changing direction of velocity is literally changing velocity.

>>720159292
>It isn't moving through the environment
then it didn't enter the portal since it's part of the environment

Relative to what?

>>720159945
Do you know what gravity is?

>>720160049
What is it?

>>720159945
All these threads just seem like Bfags playing rhetoric games since we obviously don't have a shorthand word to describe something impossible.

>>720158947
the whole point of this experiment is that the object isnt moving through the portal. The whole point of the games is moving objects through portals, the question is what happens if a portal moves around an object

>>720160049
You're asking that because you believe gravity is the only thing changing velocity. Because despite me telling you otherwise you still think velocity is only changed if the magnitude is changed.

I repeat: changing direction of velocity is literally changing velocity. If portals actually maintained velocity you would get the A outcome depicted in >>720159945

>>720160176
We have a rule B follows:
>velocity relative to entrance on entering (including relative direction) = velocity relative to exit on exiting (including relative direction)
It's extremely consistent with how portals are shown to work in the game.

>>720160306
One. It can't. Two. Even if it could, it wouldn't transfer momentum because a portal is a door. Do you suddenly pop up into the air when a door frame moves past you?

>>720160517
based on your first post it seems that you expect to fly out of a door when passing through it.

Using portals to throw jews into ovens was how the nazis managed to holocaust so many chosen people, please be mindful about upsetting others with your gruesome diagrams >>720159945

The protagonist didn't get launched that fast though, so it's clearly not B. Instead he was sucked in along with the atmosphere of earth, as it was venting into space.

>>720159789
Have the orange portal on the moon or an asteroid or in space moving towards you
assume the blue ramp portal is in space at rest
Assume I am also at rest in space
I shoot a laser (something traveling at the speed of light) into the orange portal on the moon
Does the laser come out faster than the speed of light?

>>720160841
>The protagonist didn't get launched that fast though
Yes they did: >>720158240

>>720160902
The portal will attempt to accelerated the laser but special relativity prevents the laser from ever being measured as faster than the speed of light in a given reference frame.

>>720160306
>what happens if a portal moves around an object
there is no difference between this and moving through the portal. think about it like this. imagine you're in the void of space. how do you know if you moved through the portal, or that the portal moved? you can't. it's indistinguishable.

>>720156726

What object?

>>720161504
The orange portal moon/object
And the inverse

>>720158240
As far as the game engine is concerned, both the earth and the moon are stationary objects with 0 speed. This proves nothing.

>>720159673
If the piss inherited the portals velocity then you could move the portal in such a way that it would never fall out at all

A or B?

>>720158947
Probably 95% of A posters are gaslighting at this point
Back in the day it was probably only like 25% of fakers driving it because it's a little challenging to imagine changing velocity without acceleration, but by now there's only some dust sweepings left

>>720161601
Not sure what you're trying to say. Are you still talking about firing a laser through there? Because the outcome would be same as I said before.

>>720161849
Actually the opposite. It's under A that the piss could never leave. Simply have the blue portal descending so fast it instantly catches up with any piss attempting to fall out.

That scenario under B would have the piss inherit the downwards velocity of the portal so it'll automatically fall out moving faster.

>>720162070
B. But I've seen an Afriend argue A in a similar scenario so don't put anything past them.
(Assuming, btw, that the blue portal that's not shown does not change its velocity)

>>720156181
So the same retard who said he didn't know the answer then went on a rant.

B, the ball's already through the portal, and the blue portal isn't moving. Changing where the orange portal is doesn't change where the blue portal is.

>>720160902
>bro is so dumb about physics he doesn't realize that he's describing the exact situation that already happens on a daily basis and we already have the answer to that

>>720163017
Fails to catch up with the portal because it's now moving upwards.

Only possible way you could have the portal ungulf the piss again under B is if it's accelerating faster than 9.8 m/s^2

LMAO I described you in >>720158719

>>720163000
>in after a retarded afag gets confused and thinks this webm is referring to the air pressure

>>720162424
if you have a laser, and move a portal across the laser, think. You already said it would accelerate following the velocity of the portal
thus, if a portal was rotated through a laser, it would inherit that rotation and spit out a laser that goes against what was actually seen in Portal 2

>>720164048
Are you implying that the laser beam will curve? Because light travels far too fast for that.

>>720164406
that's not an answer really, isn't it?

>>720155765
The moon portal should be moving at a parabolic velocity with respect to the earth's surface.

>>720158240
...Are you mentally retarded?
In fact, it is the other way around. Speed is relative, if A is true you appear no the moon at around ~0 mph, while if B were true you would inherit momentum from Earth, whose relative speed to the moon is 2200mph in the opposite direction.
To see A confirmed by the game, when you B trannies almost got me convinced. Lol, lmao.

>>720164850
love seeing Afags like you out themselves as too stupid to even understand what B stands for. it happens literally every thread

>>720164850
A = speed stays same, B = speed can change if portals are moving

>>720164991
I explained to you you fucking retard. The portal on Earth is moving 2200 mph relative to the one on the moon, literally same scenario as the classic A vs B problem, and you are too stupid to see your self-own.
Peak midwit gauss bell is wrong, extremes are right scenario lmao.

>>720164640
I'm not even sure of an instance of portals spinning in Portal 2. The portal/laser interactions in Portal 2, namely the neurotoxin chamber part, follows the logic of what would happen if you moved a laser pointer around. The light would without fail move in a straight line no matter what you did because that's just how damn fast light moves.

Even if you attempted to slow light down but say having a portal exit move backwards or running backwards with a laser pointer the light would still end up moving at C because that's how special relativity works. Light always ends up being measured to move in the at same speed.

>>720165229
Read the anon's post above you.

>>720165229
you're right, it is the same scenario as the original problem. which is why the ending of Portal 2 proves B to be correct

>>720165226
Earth and Moon are moving relative to each other at 2200 mph horizontally, and you get out of the portal at near 0 miles per hour, just sucked by the vacuum. You realize the player is not moving at 2200mph horizontally in the cutscene, right?

>>720165436
When you get out of the portal, you are moving 2200mph relative to the earth.

>>720160902
>>720164048
That's not how light works. The speed of light is a constant in all frames of reference, that's half the premise of special relativity. Your car isn't pushing photons out of its headlights faster when you're driving.

>>720165436
>. You realize the player is not moving at 2200mph horizontally in the cutscene, right?
Chell literally is. You just don't perceive it because that's also how fast the moon is moving. Hence B in >>720158240 being correct.

>>720165395
It is amazing you are literally looking at it and still read it completely wrong. By the way, you don't need to keep the same direction for A, you can alter the direction vector. Maybe then you will realize you are so colossally stupid you exchanged A and B.

It would be A if you somehow made a hodgepodge shitshow of real life physics and portal's physics. It's B in-universe. How is this so hard?

>>720165891
They all intuitively choose B and just insist it's A without a hint of self awareness

>>720166054
Don't worry, you will get it some day, when you grow up.

>>720166049
Compare in what way? A vs B isn't "do objects launch out of portals?", it's "do object's have their motions change on going through portals". You were literally told this already >>720165226

The cube going from 1990 mph to 10 mph isn't A because A claims the speed of the cube doesn't change.

Look, I tire of schooling you midwits in vain, so last post. You idiots should pick a lane. Is it portals moving respective to each other (which is the point of the original mental experiment) or the speed of the object entering the portal (which poses no problem for either A or B as long as both portals retain the same relative speed).
Ponder deeply about it, and when you finally realize don't feel embarrassed. We all were stupid when we were young, you guys will get better eventually. Hopefully.

That's the rule B follows. No reason to get confused. Unless you don't understand what the greentext means, which is likely given you're an Afag.

The key thing is that means the speed of an object can change on going through the portal. Which is what is depicted in the B on >>720158240. Notice the 10 mph changes to 2200 mph?

It's A that claims the speed doesn't change. Which is why A is depicted that way on >>720158240
Notice the 10 mph stays at 10 mph?

>>720166049
You're so confidently wrong, I love it

It is just that the Net force will be different because gravity will act on it the moment it moves out of the second portal.

>>720162867
>>720167148
There's no mechanism to resist the portal being pushed onto the cube, so left/A doesn't make sense
The mass of the cube must be forced through the portal, and either/both the cube and the block are violently destroyed

well then we're in a cartoon scenario where you can imagine whatever you want happens. Everything breaks if you compress it hard enough.

>>720158047
That's not what portals do. Even when travelling great distances via portal you're required to have motion relative to the portal to travel through it.

And the games do demonstrate they handle potential issues on travelling through portals but having your momentum change on passing through. There's even an entire game mechanic built around the fact portals do this.

>>720159253
You don't. You fly alongside the moon at the moon's speed. This is what happens in game. You don't stay where you were when you left the portal otherwise the moon would be gone before you know it.
If you pass through a portal, the speed difference between you and the portal must be the same on both sides

>>720155765
This is the worst scifi trope your grip would mean shit in that situation if the air was zooming that fast

It's A, I'm confident all the B-fags are just trolling.

If you fell down the portal at 10MPh, and the giant potato also had a portal on it and was traveling at 2200MPh, wouldn't you be falling 2200.02 mph at 0.26 degrees south-east?

I don't get it.............. things going through the portals keep their momentum right? soooo if the thingy isn't moving then there's no reason for it to come out flying... right?
I just wanna know why exactly do people think it would do that like is it more fun or something? is that the reason? people want the speedy option because it looks like more fun?

Bfags are all thirdies or primary schoolers who are entranced by the illusion of movement of the cube and don't have a grasp of the basic fundamentals of physics just yet. That's where they're getting tripped up.

>>720176843
That's the thing about B. Not only is it the option to go with because it makes the most sense and is consistent with how portals in the game already works. It's also the option to go with because it's more fun as well.

People arguing the A have managed to argue for the thing that's simultaneously both nonsensical and boring. The worst of both worlds.

>>720176843
Wrong. If the thingy emerges from the portal, there's no reason for the thingy to suddenly stop emerging from the portal once it's all the way through.

It couldn't create a black hole.
Realistically, the only way to compress mass enough to form a black hole is for the mass to collapse under its own gravity. Any material in the universe (and anything containing it) would just be obliterated long before any physical force got close to crushing its atoms.
The cube, and any other object small enough to be pushed through a portal, is also a completely insignificant amount of mass and even if you could somehow compress it beyond its Schwarzschild radius (for a 10kg cube this is an area one billion times smaller than electron) the black hole would evaporate instantly.
To compress the entire Earth into a black hole, roughly one billion trillion (10^24) times more massive than the cube, it would have to be crushed small enough to fit on the tip of your finger.

>Main problem with A
Cube has to displace itself along the portal in order to emerge from the portal without "moving" in the traditional sense.
>Main problem with B
Cube has to accelerate infinitely the instant it touches the portal to reach the speed of the descending piston.

Personally I find A more palatable, it's easier for me to handwave a new type of movement than it is for me to accept one that's impossible.

>>720180167
The cube experiences no acceleration in B. If you want to define it as acceleration, then you must do the same for portals changing your momentum from v to -v in the games, which should really be twice as much of a problem, yet you intuitively overlooked it during gameplay.
The problem with A is a literal logical impossibility though. It's not just "the traditional sense" of movement, it's literally movement without movement.

>emerge from the portal without "moving"
This is nonsense and you know it's nonsense
>Cube has to accelerate infinitely the instant it touches the portal
The cube also would necessarily accelerate the instant it crosses the aperture of the portal in A, in order to pass through the portal.
I don't know what you think "infinitely" means here, unless you think this acceleration is somehow happening in zero time, which is nonsense unless you mean that the cube is not moving in one moment and suddenly moving in the next, which is also true of my car before and after I put my foot on the accelerator.

>unless you think this acceleration is somehow happening in zero time
It has to unless you think the cube is existing partially in some hypothetical null space because otherwise the space moves faster than the cube.

>then you must do the same for portals changing your momentum from v to -v in the games
This is just being a pseud and refusing to engage with the concept on principle.

The cube is entering an accelerating frame of reference, and naturally accelerates with equal and opposite force as it passes through the aperture of the portal.
On the surface of the Earth you are currently experiencing the non-inertial accelerating force called "gravity."
Any object passing through any portal, even stationary ones, would still be moving between non-inertial reference frames because Earth's gravity (and other forces like its rotation) are slightly different everywhere on its surface. Is any object that passes through a portal breaking physics? What about when Chell goes from the Earth (9.8m/s^2) to the Moon (1.6m/s^2)?

The action of the cube passing through the accelerating portal seems strange and intuitive because it's not something we're naturally familiar with, but it's following exactly the same principles as any object traveling through curved spacetime.

I see what you did there.

It's only a 14 PSI difference. A car tire has 30-40 PSI.

Yes you fucking retard

>>720181747
then how can it suck anyone out? never got the trope

>>720180149
Yeah, everyday objects would need ludicrous shrinkage to breach their Schwarzchild radius

Gemini is a Bfag

And so is Grok

>Cube moves through the portal at 300km/h, then suddenly stops
?

Meanwhile ChatGPT is an Afag

Interestingly Afag Clod knows who can definitively answer the question.

Yeah....that's the point...
It's already been said, if a portal with any velocity at all is exerted onto an object at rest, then it would move itself into the space on the other side, no matter how small it is
You could use a very very long pillar if necessary, as soon as a portal with velocity goes over the top the end is near
Otherwise you would argue that that's not possible, but if you do, you would get the portal hat effect - an object refusing to travel through a portal with no resistance, or otherwise not having the velocity of the portal in motion acting on the object it is covering

By how fast it goes, duh.

Well there we have it.
Conclusively, we call say B fags are retarded.
The End.

Well there we have it.
Conclusively, we can all say B fags are retarded.
The End.

AFAGS?!
BFAGS?!
OUR RESPONSE!?!???

>>720188057
And how do you measure that?
