I'm new to this. Why would anyone say it's B? The platform the cube is on isn't moving up into the one above, so the cube doesn't have any velocity. Why would it fly out? Speedy thing goes in, speedy thing goes out according to Glados, and the cube isn't speeding. /sci/ plz explain.

>>384733904
fuck these threads`

Einstein's relativity is proven correct time and again. GPS satellites have to account for time dilation.

There is no force acting on the cube so why would it accelerate?

>>384734568
Pretend you're facing the blue portal and through that lens seeing things from the perspective of the orange portal. An object is rushing at you at great speed. As soon as it enters the portal it gains velocity. Even if the portal were to stop at 10% of the way into the cube, enough "pull" from the top 10% would result in pulling the cube out of the blue portal if the orange portal is moving fast enough.

>>384734802
So is Newton's laws. And those laws very much apply to this situation more practically than Einstein's theory.

>>384734818
The portal's force is acting on the cube, though.

>>384734960
>Practically
And portals don't exist in practice, so theory it is.

That's a terrible expanation.

What happens is that the speed the platform will be transferred to the cube. Why? Because one portal is in motion, while the other isn't. The "gate" analogy doesn't apply here because the exit point is inert, unlike the entrance which is moving. It's a simple understanding conservation of energy.

>>384734568
It's as if the entire world is moving with the portal.

So the still cube will appear to be moving until it catches up to it's surroundings.

Congrats I guess

>>384735278
Portals aren't teleporters, they are literal holes in the universe between two points. The portal itself never has force

>>384733904
The momentum is a property of the portal and will not be transferred to the cube without collision.

Bottom platform slamming up would result in B.

Are you guys fucking retarded?

You know that Newtonian gravity and general relativity go hand in hand right?

General relativity just explains it in higher detail.

It's like complaining that Newton said Pi= 3.14 and Einstein said Pi= 3.141592. Yeah Einstein is MORE correct. But that doesn't mean Newton is wrong. Einstein's model is just more precise.

That said. As a BSc in Physics I have to say it'd be A since the motion op the piston wouldn't transfer into the motion of the block. Let alone motion in the opposite direction of the forced applying """possible""" forces upon it.

>>384735849
enlighten me nigger

>>384735643
The whole point of your argument is that the force that is applied to cube from the moving platform that hits the cube will be moved to the second portal as the moving platform has a portal on it. This implies that the force is being moved from one object to another, as if the portal is physically hitting the cube and then moving to it's other portal location. What Im saying is that there is no transfer of force because nothing is actually hitting the cube, the portal itself it a hole that does not have it's own mass and therefore instantly moves the cube to it's next location without transferring force

>>384735660
How?

>>384733904
Newton's laws are absolute. We're still trying to make sense of and prove Einstein's theories in real life.

>>384735998
Portals allow you to break the laws of physics, for example an infinitely falling object

>>384735760
The earth is constantly spinning, so almost every portal ever placed in the games is constantly moving. To go even further, in 2 you shoot one at the move, another moving object, and it still works

>>384735849
>>384735886
Wait now I'm even more confused. How does that fit into play? Wouldn't B break that as the cube suddenly gains momentum without any external force acting on it?

>>384735849
There is no transfer of energy from the portal to the cube and the cube is at rest.

The cube would emerge at the rate the portal was moving but it has no momentum properties to transfer across reference frames.

You could have the piston repeatedly slam the portal into the Cube, all that would happen is a cube appearing and disappearing at that same rate.

>>384735278
Explain how the gate analogy doesn't work. In Portal, it seems like the holes don't have any influence on you, only the force on the other side have any effect. It would be like dropping a wall with a hole in it on top of you. You wouldn't jump in the air just because a wall with an opening came at you quickly and hit the ground around you.

>>384735045
Okay fine then let me rephrase since you semantic motherfuckers will force me to write out three paragraphs to send a simple fucking message.

>Newton's laws apply more practically to the situation given in the context of the hypothetical situation assuming portals exist and if it were worth arguing about the relevance of special relativity in regard to portals and their effect on objects transversing them then there needs to be defined the mechanics of a portal and what about them makes special relativity relevant to the situation in said hypothetical situation

Are you happy you fucking mongoloid?

>>384736064
Oh. But don't wormholes exist? Doesn't sound an aperture science handheld portal device just make wormholes?

>>384733904
B
Imagine an infinitely long pole instead of a cube. As the first part of the pole enters, it is forced through the portal by it's body behind it at the speed orange is traveling. As the pole continues to travel through the portal, the part of the pole exiting blue would be going the same velocity as the portal engulfing the pole in blue portal. Since it exits blue at a velocity, it now has the velocity of the traveling portal.

Now this extrapolated down to the cube results in B.

>>384736106
Yes. That's exactly what I'm saying. Both A and B violate conservation laws. The laws of physics were written to describe the real world, and portals do not exist in the real world.

>>384736207
But how does A break any laws? The cube simply ends on a slant which causes it to fall over after it goes through the portal.

>>384736213
Oh.

>>384736264
B. The moving platform's force is applied to the cube since it's stoped by ramming into the stationary platform that has the portal

>>384736192
In a wormhole you'd be crushed by the weight of gravity causing the distortion in time. So perhaps but if it were they'd need to somehow keep gravity from fucking up literally the entire earth.

>>384736264
B, because the cube can feasibly inherit momentum from the plate.

>>384733904
The problem with theory B is that it suggests that if the portal were to stop halfway through the box that the momentum would propel it out, or rip it in half. Which I don't think makes sense.

nope. The portal isn't hitting anything.

> the portal itself it a hole that does not have it's own mass
we don't know that, but let's assume. Also note that does not mean it cannot hold energy.

>instantly moves the cube to it's next location
that is some poor choice of words. I thought the portal didn't move anything according to your own post.

>without transferring force
It normally doesn't because the entrance and exit point are motionless. But since the entrance is in motion while the exit isn't, that energy should be transferred to the cube according to the laws of conservation of energy. If the portal does not follow such law, then please do point it to me when and why is that the case.

>>384736438
but how? the portal doesn't have any momentum since its just a hole that leads to another place

>>384736125
You don't understand how relativity works because you've never experienced what it is like to be without a frame of reference.

When you have no frame of reference if something is flying at you at 500k mph, from it's point of view it is still and you are flying at it at 500k mph. Both are equally valid. Neither is "actually right". This is also the reason physics get truly strange when dealing with theoretical concepts like this when dealing with extreme situations like this with wormholes or Speed of Light. It seems physically impossible to a human individual but that's still how they work.

The portal doesn't have momentum, it is more of a mathematical entity. If instead of a box it was an infinitely long rod and never stopped, the rod would continue going out of the blue portal at the speed of the orange portal.

Uhm, didn't it say that it's impossible to create a portal on a moving surface? So the whole set-up is therefore not possible.

Furthermore, such things as portals are not real, so this doesn't apply to physics as we know it since it's made up. The creator of this problem can claim any answer to be the correct one since he came up with it.

And last, I propose options C and D:
C: The cube gets crushed by the stamp because of the aforementioned impossibility to create a portal on a moving stamp, the portal could just disappear again.

D: The portal could very much stay where it is and either suck the stamp right into it as it passes through and warp it a little since it's too small for the stamp to fit through OR the portal could block the path entirely.

I could think of even more, but I'm tired.
You say those options are impossible as well? Well, duh?

>>384736796
>impossible to create a portal on a moving surface?

>entrance and exit
That's where you're misunderstanding my argument. There is no entrance or exit, they are the same point. The cube isn't ripped from space time upon contacting the first moving portal and moved to the stationary portal, it's the same location and because the platform does not touch the cube, it does not transfer it's force

I'm not that anon but the "appearance" of motion as described is LITERAL motion on another frame of reference. There's no absolute frame of reference. That's why it's called relativity.

The total system of the orange portal, cube, and blue portal has momentum that's necessarily conserved. That momentum has to be expressed somehow.

But what if it's a hole on a moving vehicle, where it's stationary for people inside it and moving for people outside it?

>>384736493
>>384736117

It does not apply because a "hole" in a wall, or a gate have the entrance and exit point always in the same state of motion or motionless. As in, the entrance point of that hole in the wall and the exit will always be together, so of course nothing should happen.

But if the exit point of the falling hole was somewhere else and motionless, the energy of the entrance would have to be the same as the exit, but it is not. And so, by the laws of conservation of energy, that energy should be transferred to whatever will pass through that hole. Else, you'd be breaking the said law.

>>384736878
The momentum is not a property of the cube, it's a property of the stamp/piston. No forces acting on it other than gravity and reactive forces.

Pushing it through a stationary portal gives the cube momentum properties. Pushing the portal over the cube gives the stamp/piston momentum properties.

These properties are conserved across reference frames.

Even if the portal was massless it would still have momentum if it was moving. By shit I did not realize the state of physics education was this bad. The absolute regards in this thread.

Considering those are the portals the scenario is describing, yes.

There's no point in trying to apply real world physics to portals since portals already violate the laws of physics anyway.

Has anyone on the portal development team/at Valve actually said how a portal is supposed to work, physically?

>>384736854
Since its bending space, no space is being moved in the process, so it is like a hole

>>384737154
You should google what a frame of reference is, the re-read the part of my post I mentioned it in.

>according to you we assign v to both elements
You're actually too dumb to understand what I said. You don't give 500k mph to both objects, you can pick one to be moving at 0 and the other to be moving at 500k mph. This is accurate either way without any outside frame of reference. The effect is the same and without a frame of reference you have no way to know.

You don't give both 500k mph velocity each other because that then means they are moving at each other at 1,000,000 mph from one point of view or another. If you're on earth, you have the frame of reference of the surrounding earth to measure your movements in RELATION to it. This is relativity. This works perfectly for our everyday life because the environment is not being moved. Unlike in a wormhole where the surrounding space itself is being moved.

Here's a children's video about relativity. https://youtu.be/AInCqm5nCzw

>>384736963
>The how would it transfer energy if it doesn't touch the cube?
Touching and hitting are different things anon. How can you say the portal does not "touch" you? What would be considered a "touch" from it?

>You know what happens when you assume
I was assuming your assumption was correct, so I guess you should know as well.

>Poor choice of words on my part. Im saying the location of each portal is linked in space time
Precisely my point! However the disparity between the energy of one another is the crux of my point.

>There is no entrance or exit, they are the same point.
We don't know if that's the case or not. And even if we did, you do know those things are not mutually exclusive, right? Especially since entrance and exit are nothing more than relative terms

>The cube isn't ripped from space time
Good thing I never said that.

> because the platform does not touch the cube, it does not transfer it's force
It doesn't need to, because it is in motion alongside the portal. And since the cube goes through the portal, then that energy should be transferred to it according to the conservation of energy law.

Portals don't do anything but be a portal. Given that — remember portals don't actually fucking exist so you have to assume what the game gives you — you have to assume it'll just roll out or whatever. Nothing in the games indicates portals have any sort of affect with momentum and whatever. It's literally a fancy window, aka a fucking hole. If a big window frame was hanging from a belt machine and it was coming toward you SUPER FAST, and you jumped up so that it would woosh passed you, would you suddenly fling off in some direction because the window is carrying some secret momentum in the air particles or some shit? No. it's a fucking portal from a made up video game who shows quite explicitly through it's in-game physics that all the portal is... is a portal.

grt b8 though

>>384737558
The points of space between the portal is being bent. The space beyond that is being moved with the portal. Think of it like space is a piece of paper. Being bent on itself to connect to points. Then you move the point the paper meets further along it to a different spot, the space behind it is moved forward with it to keep connected and if an ant was on the piece of paper it would seem as if the space and the portal was rushing at it.

>>384737219
Portals are 2 connected and fixed points. The exit and entry are always together, without both there is no portal.

I get the feeling most fags played Portal with portal assists on that would give people the impression they're 'pulled' through portals.

>>384737251
What makes you so sure the portal cannot conserve energy and transfer it to the cube?

>>384737340
the portal doesnt even tocuh the cube how is the force gonna get transferred the force of the piston moving goes into the two surfaces smashing together dumbass faggot retard fuckface

>>384737340
I think you're the retard here. It has no force that it is exerting on the cube. There is no energy loss in transferring the cube through it. All the energy that was used to accelerate it will be equal to that when it lands. If there is no fucking force on the portal to transfer to the cube, there is no fucking acceleration. If I put my mouth over some food really fast is that going to accelerate the food?

The problem is that "touch" is not an accurate enough term to measure it with. Of course, we can't really know for sure how it works since portals aren't real, but what makes you assume it is incapable of transferring its energy?

Also, the portal HAS momentum. If it didn't, it would've stayed in place. The question here is whether or not it will transfer its momentum to the cube. Which if it didn't, then where would that energy go?

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.
The portal cannot have 0 mass, as energy for massless objects can have the equation of
E = hf
Or Energy equals Planks Constant x Frequency, as Planks Constant is a finite number, frequency must be infinite.
The equation for energy can also be
E = hc / wavelength, as Planks Constant and Speed of Light are finite, wavelength must be 0.
But Light is equal to wavelength x frequency, but 0 x Infinity = 0, making light move at 0 speed if portals were massless.
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.

The actual answer isn't on here. It's obvious whenever this question pops up the only "physics" any of you have ever experienced is in fucking portal. Pic included shows the real answer C at most the cube would jiggle a little from the two platforms colliding and slide on it's platform as it is now on an incline, but it wouldn't "fall" or "shoot" out of the portal at all. The cube has no velocity.

>>384735849

>conservation of energy

There is no motherfucking transfer of energy to the cube. The portal is merely a hole. The only energy being transferred is from the moving platform to the stationary platform that the cube is sitting on. If the stationary platform is to cave under the energy of the moving platform, then maybe you can argue that the cube would move.

>>384737832
>Portals are 2 connected and fixed points. The exit and entry are always together, without both there is no portal.

I never said otherwise. But the entrance and exit not being in the same state of motion creates a different scenario.

Also, the portal HAS momentum. If it didn't, it would've stayed in place.
Hmm? If you drill a hole though a piece of board it stays on the board even if the board moves. That hole you made doesn't have momentum. A portal is just a fancy version of that isn't it? Why do we treat the portal as a separate entity instead of just a portal?

>>384736881
Good point sirs, I didn't think of that.
But my point still holds up, it's up to the games physics to decide, not bound by real science. If they ever make a Portal 3, they could make it so stuff can get sucked into the portal and gains some acceleration in the process so you can use it like a weapon because screw you, that's why!
But since I didn't play Portal 2 and knew nothing about it, I'll settle for A since one can compare it to throwing a big ring over the cube sitting on the pedestal. Maybe it would roll a little from the impact because the air sucked through the portal could work like someone blew onto the cube. I hope you get my idea.

>>384737842
They do not interact with each other. Just like you do not interact with an open doorway when you walk through it.

No contact, no transfer. Portals exert no forces, only conserves forces applied between reference frames.

It isn't because it creates the scenario of the entry and exit point being in different places. And in this case, one in motion and the other not.

No its not you dumbass. A portal is hole through space-time, a flat plane. lets use your board example. If you wanted to get from one end of the board to the other you walk across it. using a portal would essentially curve the board until both ends are touching, you could then drill a hole between these two points. Boom, a portal. reminder that these two points never move, the space around them does however.

So if we are ignoring all the logicality of something beyond it's most basic features to make it true, then all the irrelevant 'relatively momentum' bullshit can't help.

So the cube is coming out of the blue portal.

What happens to your hand if it's where the cube is going to be coming from?

If there is no force acting on the cube coming out of the portal then your hand would stop the cube and the cube would either be crushed or the pedestal underneath is would be crushed.

If there is force acting on the cube coming out of the portal then your hand would be taken off as the cube flies away. Anything that has the force to push your hand away at that speed it would be moving possesses the force necessary to propel itself through space.

>>384739281
Who are you quoting?

Ok you stupid fucks how about this:

Instead of a cube its your body, and the system is applied to you in the same way but stops with half of you on each side of the portal. do you:

A. Experience two different gravitational forces on either side of your body and nothing more

B. Get nonsensically ripped in half by the non-existent momentum of the portal because you're a mongoloid who thinks B is correct

>>384739414
It isn't. The exit point never moves, it is a stationary anchor. When you move through a portal, you keep your momentum. The portal's momentum doesn't affect your momentum.

>And if the Portal has energy,
>if
a portal can't have energy, its not an object or matter

>>384739497

Huh? Wouldn't the cube just not fall down on the ground like it shows in A and you'd be holding against essentially a slanted wall?

>>384739371
All portals does is link up different spaces

>>384739481
B. A moving portal has different properties than a stationary portal. With stationary portals you only have to consider the object moving through them. With a moving portal you are adding force to the system. If half of any object were being tugged at from one side the rest of the object would follow if it's strong enough to withstand that force or it would be torn apart.

Movement of the portal is a change in the space-time bend/fold. Intrinsic properties of the portal are changing only.

The net force of the platform it's on. "At rest" doesn't mean "no forces are acting on it at all whatsoever". It means that all of the forces which are constantly acting on it are in equilibrium. The portals disturb that equilibrium.

I'll assume you're being serious: If the portal is not motionless, it is in motion. If it is in motion, it means it has energy. Both the stamp and the portal are moving. Hell, for the portal to MOVE in the first place, it needs to be interacting with the piston/stamp.

Well when they modded the game to allow portals to be shoved, the game's physics engine resulted in A so I'd say that's about as canon as you can muster.

>>384741232
Only when it is being forced to by the other object in this scenario, which in your example would be a moving wall.

Even assuming that portals did have momentum, why would that be important to the blue portal. It hasn't moved at all.

Implying it isn't a scam.

The cube does not posses the kinetic energy, therefore it will simply quickly emerge from the other side but with little momentum, as seen in (A).
The energy of orange portal's platform will be absorbed by the platform where cube was initially located, like two hands clapping.

Personally, I'd say that (A) is what makes more sense as I trust newton on this type of thing.

But (B) is so much more fun as far as vidyas go

>>384736330
This is precisely why Valve didn't let you put portals on moving platforms. Bugged physics. Don't post it like it's the solution, it actually shows what the wrong answer is.

>when the portal moves it does not gain momentum
It's not a question of gaining. It has momentum. If it moves, it has momentum.

>and the intrinsic properties of the Portal change to maintain the link between portals.
How do you know that's the case? What properties were those? What did they change to? How would the link between the portals not be maintained if it didn't change its properties?

>>384741000
While it appears to emerge at speed from one frame, it has no force propelling it through to the new reference frame.

It would emerge from the portal at speed due to the piston but go no further.

Portals conserve energy across reference frames, it does not transfer energy between objects. The new reference frame would trigger a new rest state as new forces are acting upon it, namely gravity and reaction forces.

>>384741194
Guess what? Portals don't have any mass AT ALL. So it wouldn't have any momentum at all.

p (momentum) = Mass(m) x Velocity (v)

The real answer is this is why the relative positions of two portals must remain constant. Neither option makes sense.

Right. I know the answer is actually neither, but we're assuming it can. So I'm using the reasoning of the scenario to dismantle anon's arguments.

>>384741321
It would be important because the momentum of orange would have to go somewhere. If not to the cube, then where?

I realize we're going in circles here, but I've yet to see someone explain this to me without contradicting themselves or disregarding the laws of physics.

>>384741776

>guys, could a light-saber cut captain's america's shield???

>>384741776
There's no force to keep the plate with the orange portal suspended in air with B so it will continue to fall resulting in A.

>>384740189
Ah but you see, in that scenario both portals are moving and cancel each other out.

>>384741678
No because there is no fucking lift.

>>384741776
That depends whether or not the energy orange has is enough to bend whatever that pillar is.

>>384741564

>>384741776
A

>>384741776
You have it the other way around, friend.

The retards who believe A is correct in the OP should believe B is correct in your example.

Those that acknowledge the OP is B, since an object entering a new space already occupied by another object would literally have to push it out of the way because they cannot occupy the same space, would use the same logic to conclude A in your example. Parts of the structure entering would forcibly push the rest of the structure towards the wall and result in a bend.

You should switch the answers in your image to avoid confusion.

Its the exact same scenario relative to the cube, only your hand moves because the orange portal ONLY is in motion, from your POV you're not even seeing the cube coming at you, you're seeing yourself move toward it.

>>384741784
>It might not be B
It isn't might not B, it is not B, because you inherently assume the portal can move in the first place, which is entirely incorrect.

>>384741834
>It would be important because the momentum of orange would have to go somewhere.
No see then it would have made more sense to say where did the energy of orange go. Anyways, I can't answer that because I was already under the belief that portals do not have momentum seeing as how they aren't objects.

Provide modeling that shows that the vertical beam does not absorb it as elastic deformation.

>>384742093
No because the falling piston is pressed up against it

>>384733904
None
When a surface with a portal moves, the portal vanishes

>>384741757
Because when you drop a basketball into a hoola hoop the basketball keeps its momentum and flies out od another hoola hoop with the same energy it fell at.

>>384741776
B

>>384742193
I guess I got the colors mixed up at some point, fuck.

If they aren't objects, and thus can't hold momentum, then it couldn't move in the first place.

lol faggots this shit is pointless because neither would work at all

>>384742293
because portals are like hula hoops, you fucking retard. if you play portal that is very obvious.

>>384742168
I think anon was referring to the difference between the argumental prowess of A and B more than anything.

>>384741749
Even if the portal is stationary on earth then in say, the moon's frame of reference it has momemntum.

>>384741676
How so?

>>384741776
C. everything explodes

>>384733904
A fags, explain this.

Let us say the orange portal is coming down at 50 meters / second. This means that the orange portal goes from the top of the cube to the bottom of the cube in a split second, aka very fast. This means that the cube has to appear outside of the blue portal equally as fast.

When more of the cube tries to go in, it has to push the rest of it out because it needs to occupy the space immediately outside the blue portal. If you're ignorant enough to not know what happens when an object attempts to enter the space of another object quickly, use your hand to punch something and see what happens.

Are you telling me that the cube exits the blue portal INCREDIBLY FAST and then magically stops and plops to the ground?

>>384741776
For this one and the one in OP.
Think of the port as a empty picture frame or window frame, that is all it is, is a frame but instead of leading directly to the other side of the frame its to a different location.

in >>384741776
Its A because the A is now forced onto itself and will bend under its own force in a confined space. It can't be B because there is nothing to old a frame up.

In >>384733904
Its A. As already explain above, its its just a frame that is going around an object the object would just be on the otherside maintaining its momentum. There is no way for it to be B because if you take a hoola hoop and put if over some they don't become lighter or fly off in the opposite direction.

Its simple, Portal are just simple frames that lead to different places.

>>384742162
No. You've fundamentally misunderstood the point I made in the first place. Your hand is not through the portal. Your hand is outside of the portal waiting for the cube to come through. I'm asking what would happen to your hand as the cube comes through the portal. If your hand moves as the cube is pushing it, then the cube has force that is moving your hand out of the way. The faster the portal is moving, the faster the cube is moving, and the faster your hand moves away. That force does not disappear once the cube is completely through the portal. It doesn't disappear at any point. The cube continues to move through space because is now has velocity, as is EVIDENT with your hand being pushed away.

>>384742326
gravity. it depends how strong the bar is.

if you have an infinitely strong press pressing the portal down, the bar will always be crushed.

If we weren't, there would be no thread, anon.

The Cube's momentum isn't preserved because the vector changes as soon as it exits the portal. So your asking a stupid question about how an inherently wrongly designed physics engine works- A first year physics student could tell you this, no need to get into the great minds.

Runway is too short and the wings are obstructed by the rest of the treadmill

>>384742162
I just explained where the misunderstanding came from and you posted a pic for an example that wasn't described. The hand doesn't go through the portal, it just stays in the space where the cube would be when IT goes through the portal.

>>384742343
I made a previous point about drilling a hole through a board somewhere above. I think of it like that.

>>384741776
What the fuck is keeping the B portal suspended in the air? Wouldn't the panel with the hole in it keep going because it hasn't made contact with anything?

>>384742162
I should have said orange side, since the portal itself is obviously stationary

>>384742580
But that wasn't specified

>>384742061
>would literally have to push it out of the way because they cannot occupy the same space,
Well yeah, you're still essentially pushing something through a doorway at that point but because it's the portal moving and not the surface the cube is connected to (or the cube itself) that is being propelled it, it will travel no further than the amount the portal travelled over the cube. After this transfer there are no remaining forces to act upon the cube. It has gained nothing form the previous reference frame and forces changing the frame have been exhausted.

>If we weren't, there would be no thread, anon.
In this thread we are debating whether a hole in space can give energy to a cube

>>384742231
Without knowing the physical mechanism of transport we can't say it doesnt. Just that A is definitely not the answer.

Given that 75% of the thread can't grasp basic relative motion I'm trying not to muddy the waters too much.

>>384742627
>I made a previous point about drilling a hole through a board somewhere above. I think of it like that.

>>384742530
>a hoola hoop is a wormhole
A fags wearing their stupidity like a badge as usual.

>>384742326
The portal is being pulled down by gravity. There is nothing stopping this portal at any point. As is continues to move down, the bar is going through it with more and more force the lower the portal goes.

It doesn't make sense unless you start thinking with portals. It literally doesn't matter how strong the matter being transferred between portals is because more and more of that matter is being pushed through. Something's got to give, and it will not be a portal made of essentially infinite energy.

>>384742749
> whether a hole in space
But it's not just a hole in space, is it? We've been over this numerous times. These analogies do not apply.

>>384742528
That's not how fucking portal work. Its simply a wormhole. In others words is a simple direct link of two space. So you could move between them completely naturally like in any other space.
