A is literally the only correct answer

>>377265068
This meme has gotten old.
Since the platform doesn't apply a force on the cube, and supposedly neither does the portal, the answer is A.

Portals don't exist, this is literally an argument between two faiths.

the table apply a reaction force against the portal pressing it. The cube suffer this for a short moment at the moment and only when the portal touches it. The cube gets in the portal as fast as the press goes down at the moment and "speedy thing goes in, speedy thing goes out", portal conserve momentum.

>>377265068
portal is like a hole

you can literally try this at home.

>>377265068
For the umpteenth time, it's A in your example where the portal'd side is what's moving, and B if it were the table and the cube that's moving up towards a stationary portal.

>afags will refute this

>>377265843
>the table apply a reaction force against the portal pressing it
the portal has no mass, so there is nothing to receive that force, meaning the momentum of the piston is never transmitted to anything. Portals conserve momentum, and the cube has none, resulting in A.

>>377265068
Stanford Physics major here.

A.

Portals are unable to function on surfaces moving laterally to its orientation.

All you'd get is a crushed cube.

>>377266323
literal who? Why would I take some no-name's argument as valid?

Cube enters at the same speed of the blue portal. It's B.
>>377266480
>the fucking coder of portal even says it would be B

>>377266228
Doing it in source games causes B to happen IIRC.

>>377265068
Both wrong.
The moment the portal surface starts moving, the portal vanishes as it always does in the game for moving portal surfaces.

Thus, cube either gets flattened or blocks the mechanism from crashing down all the way

Maybe I'm mistaken, but didn't they confirm that the GMod version was bogus?

>>377266332
ok i admit it makes sense and you are right.

In a different context, what if the press hits so hard (10.000km/h) the table that it goes down a bit, lets say 20cm, them the cube would fly away (as B) by inertia ?

>>377265068
More of an inbetween
The cube would preform a small hop

>>377266703
Probably, though not by much. If anything, it would basically hop out of the portal.

Cube enters at the same speed the portal falls on it, and exits at the same speed. Afags think it loses all speed once it exits, while Bfags understand Conservation of Momentum

It's B.

if you say otherwise, you're a retard who goes to shitty state school

>>377266703
it should, but it would depend on the elasticity of both the table and the cube.

>>377265068

Take a sheet of metal.
Take a cube that's smaller in terms of length and width than the sheet of metal.
Carve a circular hole in the sheet of metal that's larger than the cube.
Slam the sheet of metal down around the cube so that the cube goes through the hole.
Does the cube go flying into the air?

>>377267346
The sheet rapidly decelerates in your example (relative to all it's surroundings). The exit portal does no such thing.

>afags can only resort to shitty hole metaphors proven wrong time and time again

>>377266662
but it can moves in 2

>>377266927
>>377267093
Wouldn't that be the same as applying [press mass]*a
a = 10.000/t
and "t" being the amount of time it takes to a object moving 10.000km/h to run over 20cm.

Wouldn't that be a big push if the cube mass is something small like 10kg ?

>>377267082
Well Harvard isn't known for putting out the brightest recently, so of course a moron like you would think it was B

>>377267516
?

>>377267582
And which community college do you go to?

>>377267485

The portal is being accelerated on a sheet of metal, though.

If there were no sheet of metal, there wouldn't be any force being applied to the table, and thus none being transferred to the cube. It would simply have the environment around it changed.

>>377266954
I use to think this, but once the cube enters it stops because once the press touched the table there's no other "force" acting on the cube to push him completely out of the portal.

Oh man I sure do love living in Aworld where holes can have their entrance move at the speed of a billion miles and the exit can remain stationary without any sort of distortion and entering a hole compresses your body into a single atom.

Portals are stationary. The orange portal would disappear the second the piston started moving.

>A moves at 40mph to envelope B and is ejected at C which is moving at 40mph for a net change of 0
This is a door

>A moves at 40mph to envelope B and is ejected at C which is moving at 0mph for a net change of 40
This is a non existent portal anons are sperging about.

The numbers must be equal not counting gravity and wind resistance.

>>377267786
It's even more fun to live in Bworld where if I run through a door, the door gets ripped off the wall at the same speed I ran through it.

>>377267876
No, there's a scene in portal 2 where one of the portals moves while the other is stationary.

>>377267582
but how do you know the cube is moving or not? all the picture says is that the cube could be moving into the portal or the portal is moving into it. given that its a white void its most likely b. but if your going by abosolute frame of reference which doesnt exist then a is correct.

>>377268000
>scripted event
these threads are always the same
im out

the momentum of the pillar is irrelevant because it never actually touches the cube. the pillar goes down far enough that the blue portal envelopes the cube and transports it through to the other side. If the pillar itself actually hit the cube, then it would be B.

>>377267802
it's the same argument. answer is still A.

Portals can't be on moving platforms

look at the image you stupid fuck, it clearly illustrates that the above pilalr is moving and the bottom pillar is stationary.

>>377268000
Those portals could only move sideways IIRC, not forward or backward like here

>>377268103
>i'm wrong

>>377265068
IT'S IMPOSSIBLE. You have 2 different resting values.
You can't have one side of the portal enveloping an object without the other end moving in the opposite directing to un-envelope it. both ends of the portal either need to be stationary or moving in a way that they would allow the object to enter and exit like a extended doorway.
The most likely outcome would be the cube would just get smashed to bits or the portals would break.

>>377268272
The cube is still entering a portal falling towards it. It has to be exiting at the same speed the portal falls or else it will be crushed.

B. Anyone else saying its A is a weeaboo faggot.

>>377268516
crushed by what? the portal has no mass, if it did, you would experiment some kind of resistance when going through them, but you don't.

>>377268516
so basically this whole argument revolves around thinking with shitty portal physics instead of actual physics? Has this actually been tested in like gmod or something?

>>377268516

Portals aren't doors. If an entire dimension was moving toward you in a portal and you jumped as it passed you would not instantly start moving with it. Although at this point it might be pointless to argue.

>>377265068
Alright I have a better question than yours op.

It is moving, and it can't NOT be moving. At think point I'm not even saying that the answer is B, but it actually can't be A. Put a stationary object in front of the exit portal. When the cube exits the portal it collides with the object. Now we already established that this object was stationary. So if two objects collide, and one was stationary before the collision, then the other object (in this case the cube) must have been moving.

>>377265843
I refuse to believe this isn't bait.

>>377269089
That stuck in the portal thing is what would happen (it'd be like sitting in a window ledge), and is also the reason why A happens with the box (because instead of being to hang in there, the pillar the box was on is in the way, so gravity pulls the box to the ground).

The entire point of portals and (also what makes them impossible) is that they ARE just doors, you just come out somewhere else.
That's why it's A, because portals are fucking bullshit. If we created real world portals they wouldn't work like that, and we'd get B.

But if we think of the portal as a tunnel instead of a hula hoop, the cube still doesn't move. If you suspended the cube and threw the entrance of pic related at it, the cube still won't move, even when it comes out the other side, even if the other side is twenty meters away and completely stationary, because no force or momentum is being imparted to the cube.

A, because there isn't any force acting on the cube (other than gravity making it tumble down the angled surface). If you're wondering if it would fall back into the portal the answer is no because on the other side is a flat surface which effectively becomes the flat surface of the angled object.

If we assume the inverse are true

What kind of fucked up logic is this? You don't immediately accelerate to the speed of something that travels around you. There needs to be a force that causes B to move, otherwise B remains stationary. It doesn't matter how fast A is moving if it never touches B and imparts that force. B is moving at 0mph and leaves the portal at 0mph. How does A, which never interacts with B, transfer enough energy to immediately accelerate it from 0 to 40mph in an instant?

Go >>377270361, and read it again if you have any difficulties understanding why A cannot be the case.

It's only a paradox if we accept your completely unsupported notion "moving portals can't cause acceleration" which we cannot show one way or another without exploiting the game. The fact that A causes a paradox and B does not is the argument proving it isn't A.

>>377272229
Because it's not moving. The portal is.

>>377272229
The cube isn't moving through the portal you idiot the portal is moving around it. There's literally zero force on the cube whatsoever

So A has already been proven to be impossible. Has B been proven to be impossible as well anywhere? Then we could disregard the picture and come up with new ideas of what would happen

That's not the cube moving that's the portal moving around it closing the distance between the portal and the pedestal.
What's so hard to understand about that?

The only way B can be a feasible scenario is is the pedestal is moving the cube into a stationary portal.

It doesn't have any momentum at all until it hits the slant on the other side where it's affected by gravity and slowly slides down.
Meanwhile in scenario B you have it suddenly gaining momentum as if someone threw it into a portal but it's completely stationary.

as in 'the cube is moving away' from it
as in the cube is MOVING
it is impossible for the cube to COME OUT of the STATIC portal on the right without MOVING out of it

>>377272912
Even if the portal is a tunnel and one side is the moving and the other is stationary, you still don't gain any momentum unless the portal actually touches you, which it never does. You don't suddenly accelerate to 40mph just because someone threw a plastic tunnel at you at 40mph.

It doesn't matter how fast something flies around you, unless it somehow gives you its momentum, you'll stay completely still.

No fucking way are you a physics major, think about relativity.

From the blue portal's side the cube and everything past the orange portal side has a velocity equal to that of the descending orange portal.

From the orange portal side the cube is obviously stationary. So the question is a paradox, neither A or B make sense.

You're right, because then it'd obviously be concluded it was B.

To use your capitalization:

The orange portal is MOVING. It leads to the space outside the blue portal.
The cube is NOT MOVING.
The blue portal is NOT MOVING. It leads to the space outside the orange portal.
The cube appears to MOVE OUT of the STATIC blue portal.
But both the cube and the blue portal are NOT MOVING.
So what is MOVING?
The orange portal is MOVING. The orange portal leads to the space outside the blue portal.
therefore the space is MOVING ONTO the cube.

Repeat:

The orange portal is MOVING into the cube.
The space outside the blue portal is MOVING into the cube.

But there's an important point you gloss over: if this is detached from reality, then anything goes. It would be exactly as valid to provide option C, which is, the piston slams down and then a million rose petals delicately waft out of the portal. But on the other hand, an actual understanding of physics reveals exactly why this can't happen (within the scientific paradigms currently on offer), which is, the answer is dependent on the choice of reference frame. I'm not personally married to relativity, but most scientists are.

From what we can tell, a Portal in this case is a perfect hole connecting two areas of 3 dimensional space through some extra-dimensional wormhole.

It's not moving at all. The portal is moving downwards on it simulating motion.
In other words the space is moving around it rather than it moving through space.

Oh boy.

I think I understand where the confusion from B. comes from. What they're assuming is that since the orange portal is moving downward, it would be like if the entire room is moving that direction from the cube's reference.

If the bottom platform was moving up to the orange portal, no one would deny that B. would be correct in that scenario.

>>377265068
Isn't this just an over complicated version of the Bug-rivet paradox?

>afags can't read

>>377274376
but the problem in OP's pic does not work like that. only one side of the hole is moving, the other one isn't.

>>377274398
It's not confusion, both A and B make sense from two inertial frames of reference.

Everything has a velocity beyond the orange portal from the blue portal's point of reference.

Put it another way, what if the platform upon which the cube rests is made of glass, and we are standing under the glass, looking up.

If we are to believe that B is true, then what we see is the portal coming down, swallowing the cube, and the cube also suddenly rocketing upwards into the new space, which doesn't make sense. It would make more sense if it simply flopped into the next space.

On the other hand, if we are standing on the other side of that portal, in other words, looking at the cube from the other side of the portal, then the cube appears to accelerate towards us, and flies into our space, which would be consistent with how we understand the space we're in. If it simply flopped, this would be strange.

This is the issue, is that either A or B will be correct depending on which inertial frame you happen to be standing in. It's a paradox owing its power to the impossibility of a video game mechanic.

The only one of these that is possible is A, space time golds around the cube moving the points of space from the orange portal fall onto the cube. The cube is never in motion. But even that should be impossible.

The portal drops on the cube, but rhe mortal is met with resistence when it hits the cube and stops.

Okay, you're on the blue portal side, looking through the portal.

Does the cube have a velocity relative to you as the orange portal is descending?

What? No, A is just as right as B- it's a paradox.

>>377274640
Not an argument.

>>377275013
B can't be correct in this scenario because the platform the cube is on is completely stationary. For it to shoot out the cube would have to have a force acting on it as it went into the portal.

>>377275135
portals don't conserve energy

>>377274818
>From the portal's frame of reference everything past the orange portal is in motion.

And? It doesn't mean it will result in A.

>>377274956
Not him, but relative to you, yes. That being said, the velocity is relative. The cube doesn't have any kinetic energy.

>>377275135

You are on the blue portal side looking through the portal.

Does the cube have a velocity relative to you as the orange portal is descending?

Does it appear like the cube is moving towards you at a steady speed?

neither is right.
portals just like time machines are sci-fi shit

>>377275013

Put it this way, Anon. When blue drops, everythinf on the orange side is being moved downward. The air can move out of the way of everything, but eventually it hits the box. The instant the box toucjed the portal, thr box is being pushed by everything on the orange side. This is because part of the box is now on that side. The box exists in the space being pushed into the box. Imagine holding a box and applying pressure from both sides, or even just the top.

>>377275249
Which is why it's both A AND B.

From the blue portal side that relative velocity doesn't just "Disappear".

>>377275251
To us it appears as if the cube is moving but the reality is that the platform and cube is completely stationary and space is moving around it.

It's B. And yes you could get perpetual motion out of this bc portals break physics.

>>377265068
Neither.

>>377274956
no? the cube is stationary, the only thing that has velocity is the portal which immediately stops as it reaches it, there is no reason it would result in B

I think you are being confused by how relative velocity actually work. If there is no portal involved, even then the cube has relative velocity, the cube will still not crash into you if you suddenly stop before it.

The problem here is that we have two inertial frames of reference that can't be reconciled.

If you stuck your hand through the blue portal as the orange portal was descending. From the orange portal's side your fist would have a velocity, from the blue portal's side you'd be stationary.

Would your fist hurt when the orange portal reached the cube, or would you feel no pain because- hey- both you and the cube are stationary.

>>377275669
See:

>>377275953

Not him, but if the box was in a different spot of the room, then it still looks like it's coming at the orange portal if you look into it, but no one here is going to expect it to move in that scenario.

The box really exists on both sides of that portal, and I don't think a single person in this thread arguing for A or B is taking that into account.

>>377276053
Right? Because relative to you, standing still, the cube has a velocity.

From the orange portal side it would be like you punching a wall, from the blue portal side it would be like the cube flying at your fist.

So why would the cube suddenly lose that relative velocity as soon as it exited the blue portal?

>>377276062

The box never comes through the orange portal so no you wouldn't feel pain.

However if you stuck your arm through then your arm is going to be crushed upon contact with the box becauae your arm is more malleable than the box.

A moving portal can't have a motionless object enter it. The portal pushes the object away, and if the object can't be pushed then the portal either crushes the object or stops.

It's more akin to placing your hand in front of your face and moving your head back and forth. your head being the visual from the perspective of your fist and your motionless hand being the cube.

One more time, the cube completely motionless.

Accounting for the wind pushing the hand back (thus, hand not stationary), B.
Not accounting for the wind, A.

>The box never comes through the orange portal so no you wouldn't feel pain.

I honestly can't quite get my head around this, why would it be any more possible for your hand to enter the stationary end of the portal than the box to enter the moving end?

>However if you stuck your arm through then your arm is going to be crushed upon contact with the box becauae your arm is more malleable than the box.

The point here is that we're talking about two inertial frames of reference, the problem is a paradox because the two frames can't be properly reconciled.

>>377276706
You're basing that on the limitations of the game and the fact that portals can't normally be placed on moving surfaces like that.

>>377269461
It's a reference frame problem. Would acceleration/deceleration of a portal have an impact on everything else in the world?

Honestly, I think the entire setup violates conservation of energy/conservation of mass.

>>377276084
>moving hand is stationary
???

>>377276869

I'm basing it on the fact that the room is moving towards the box, air included and that at some point part of the box enters that portal and becomes part of that room that is being pushed towards the box.

riddle me this

EVERYONE HERE OWNS THIS GAME. ANY OF YOU CAN GO INTO THIS GAME AND JUST DO IT. THERE IS NO NEED TO GUESS ABOUT WHAT WOULD HAPPEN. THIS SCENARIO LITERALLY OCCURS.

Your hand isn't stationary when you move it through the portal. If you were standing where the box is, you would be crushed. There's no magical property attached to your body.

>The cube isn't moving at all anon it's completely stationary.

I'm honestly getting a little frustrated now, are you trolling?

This is going to be my last post here.

Listen: From the blue portal side, relative to you, the cube has a velocity. If you stuck your hand through the portal, your hand would have a velocity relative to the cube.

If your hand collided with the cube, it would be like punching the cube at whatever velocity the orange portal is moving.

This despite the fact both you, and the cube, are completely motionless.

>>377277030
B

>>377277030
C if the orange portal is moving at a speed.
A if not.

B would require the block move into the portal.

>>377277042
This scenario doesn't occur

>>377276994
It's clearly an illusion, the hand is not moving it just appears to be I swear

>>377277030

None of these. The cube never crosses the portal.

>>377277097

You can recreate it.

It is B and stop posting this already.

It does, absolutely.

Relative to the blue portal side the orange portal literally imparts a velocity on everything in the universe relative to the orange portal.

>>377277228
I never did read redwall stuff.

Is it any good if whoever reading it isn't 14?

>>377277084
>the cube has a velocity.
It has no velocity, momentum, pushing force or anything. It's stationary until the force of gravity on the slanted where the blue portal is placed begins effecting it once it goes through.

If you stuck your hand into the blue portal then your HAND would be moving at the speed the orange portal is currently moving at while the remainder of your body remains motionless.
In other words the motion comes entirely from the orange portal and the surface it is resting on.

>This despite the fact both you, and the cube, are completely motionless.
Your hand is in motion.
Your body isn't.
The cube isn't.

>>377277093
it clearly says the portal is moving fast, you damn illiterate
also C is obviously the most impossible outcome and you've got to be legitmately retarded to pick it
why would the plank go flying but not the cube?
