So lets say your energy creation method works.

No suppose the portal guns can only be made out of... I dunno, let say... an orphan? What then?

potentially, this method could generate enough electricity, if magnets were involved, to power a home. With enough magnets, rods, and portals, one could power the world without using a a drop of fossil fuels.

Using the power of graveity to power the could alter the Earths rotation or axis. Just think about how every thing has gravity, how much is determined by its mass. The rod isnt just being pulled tward earth but pulling earth tward it. Because the population in the northern hemisphere is greater than the southern one, there would be more of these machines there then in the south. This would have a pull on the north end that isnt as strong on the south end.Changing the earths rotation could change world climate soo much that it could cause a mass extinction to every animal not given stable homes by humans. If the days become longer, night time would be freezig cold EVERY WHERE and days would fry us. And lets not forget the possibility that we drift to close or far from the

Theoretically, let`s say that there is no friction caused by the rod passing through the portal, and that gravity remains constant, meaning that it will always drop from the ceiling towards the floor, letting the rod go would mean that it would continually fall, even though it has been soldered together. This would then mean that once it reaches terminal velocity it will remain at terminal velocity until acted upon by another force, creating, in essence a perpetual motion machine that will never slow down, or speed up, or stop for that matter unless acted upon by another force. If portals are invented in my lifetime I will try this, and see what happens, and potentially, this method could generate enough electricity, if magnets were involved, to power a home. With enough magnets, rods, and portals, one could power the world without using a a drop of fossil fuels.

If you let the orange portal fall, it would bend the bar, if you had enough force to move the portal at all.

If you shoot another portal, the rod will mend into the wall at one end and break at the other.

no skye is wrong, read the question again. "the rod is long enough to meet the other end" do the distance between portals being in front of the other would make a rod of the same distance look like its never ending. hence the capability to solder them together.

@misho, just consider that the portal gun takes a lot of power. It doesn`t just generate perpetual motion. Rather, it creates the required energy shift by a constant stream of power from the gun, which explains why the portals go away when you die.

Play the game. If something is in the portals, they will not move. You can`t close a portal on something.

Ok I can answer this!!! When you solder the 2 polls they connect to teachother from end there but not there other ending sides so its just a long pole now in too close of a sync of potarals to get out and seemingly enough would be stuck, if one portal is changed the other will let it out of the vortex due to interdimentional theroies and relative space within "connecting realms"... With the last picture it would be inpossible because the pole would "come out" of the portal and hit its origianl causing it to move in the same action as the starting strand. Also yellow portal is troll portal!

One thing that always bugged me about Portal is that the portals don`t seem to affect gravity. There is no obvious reason that the gravitational field should not pass through portals. Like, the area between the two portals should be gravity-free or something if they are one above the other. Otherwise, you could easily have a perpetual motion machine by ensuring the area between the two portals is vacuum (so terminal velocity isn`t really an issue anymore). In fact, I have trouble picturing portals that allow for conservation of energy, except maybe stationary bidirectional portals: a|b a|b (| portal, a <--> b).
For B), in Portal, portals tend to close as soon as the surface they are on moves. Assuming that isn`t the case, the rod itself should push back, preventing the portals from moving together. The problem seems to be equivalent to trying to crush a rod, by pushing at it from both ends.
As for C), as the original orange portal closes, wouldn`t it just cut the rod?

First off, is spelled solder, not soder. My first clue the creator of this paradox was stupid.

A) The rod moves downward in a loop, accelerating until it reaches a constant speed based of gravity and resistances (mainly air)

B) and C) the movement of the orange portal would result in the destruction the rod that is passing through the plane of the portals resulting in a clean cut and the rod would once again be the same length.

You should be doubting the tail-end of your (2) theory as well - the distance between two portals never affects the state of the transient object.

1. The pole will accelerate downwards until it reaches terminal velocity. Mass that fell down reappears up and continues falling.

2. If the portal is lowered, the rod will be crushed. There can not be a portion of it that stands by in some magical infinite space which will prevent the crushing. At any instant, 100% of the matter consisting the rod that enters a portal will come out of the other portal because thats what the portal does. The spec of matter that goes through here instantly appears there so lowering the portal is like holding the rod between two plates like what the letter H looks like and it will just squeeze it. Also, the opposite can happen with the portals spread apart, it will stretch the rod.

3. It will bend/snap/jam itself.

Ok - so the closing of the portals would makeup for the paradoxical coupling of an unbent rod to itself, in its creation of two new severed ends! The conservation of energy is maintained.

But Ebola, as for my second question - if the portals contain no volume within themselves, then what of the consequences for attempting to access a solo portal?

And also - if matter is not being `rematerialized` from the `exit` portal in order to account for the remainder of the material being introduced to the `entrance` portal, then isn`t its trajectory having to be bent on some, perhaps quantum, level?

@suicism... no remember the portals are only connections between real space they have no volume within them... so we are seeing 100% of the rod at all times, the face that it is connected to itself is just a anomaly of the spatial loop. so no matter how the portals were cut off. if the spatial loop is removed we are left with a bent rod.

Or ebola (3.5), would we theoretically get a `circular` rod if we were able to deactivate the portals non-destructively?

By the way, has anyone ever asked - what is the destination of only ONE portal? What would be the consequences of entering it?

3.5) if you "shot" another portal in another location that portal would collapse the spatial loop would be broken, it would be a single rod with one end against a wall and the other barely resting in a portal to another location.

3) this is a similar case to case 2... as you tried to move the portals out of line with each other, the rod would jostle around within the boundaries of the portal ovals themselves until it became pinned against the walls of the portal effect. this would then "bend" the rod just like placing a stick over your knee and pulling.. the rod would bend or snap, and the pieces would fall out of one of the portals as a single chunk. but that is all

2) if you tried to move the portals apart the effect would be that the rod would be stretched until it snapped in the middle and "fell" out of the spatial loop of the portals. this is because as the top portal moves away from the bottom one in real time, it is trying to draw the rod out of itself which would be "pulling" it into the bottom portal... and same as the bottom one became further from the top one, it would try to pull the rod into the top one and out of itself. the net effect of any movement would be a stretching force on the rod until it snapped... now whether the rod was able t feed any force back into the portal itself leading to a "resistance" in moving the walls the portals is on is never addressed. so I will leave it alone.

A)yes gravity would still affect it so it would keep falling for the same exact reason you would in the game.

B)a portal teleports matter but it also seems to stack it perfectly back in place how it was previously. If it didn`t do that anything going through the portal would be an impossibly thin layer of all the matter teleported on the surface of the other portal. so if you tried the push the portals closer it wouldn`t allow it because it would have a solid surface above and below it. there would be no room to stack the new matter because the other part of the pole would be in the way.

c)if you crate a new portal the previous one ends not moves to the new location. so the pole would be "cut" where the old portal was located.

Im sorry I have to chime in cause theoretical processes are a hobby... ok based on the fact that the rods are connected between the portals, then the point that enters the orange portal is attached to the point exiting the blue potal... 3 scenarios are suggested. 1) if you dropped the rod,it would be accelerated by gravity because 100% of its mass would be "accelerating downwards" the fact that the mass that passes through the bottom portal and out the top one doesn`t change that mass`s momentum... so it would fall and endlessly accelerate to terminal velocity(although because it was a rod with no end, the only resistance would be shear friction with the air... but it would eventually overcome gravity`s acceleration.

All of you talking about the atoms being de-materialized and poo have never played the game. It`s not that simple.

The portals are, literally, worm-holes or folds in space. Everything travels through the portals with perfection, including light itself. Now, if you moved the portal, the rod would, undoubtedly either stretch or crush itself until breakage occurs, which would be dependent on the material used to create the rod.

So, going back to the comment on the post: You`re an idiot. This is common drating sense.

Well it all comes down to how the portal functions - that is, whether the matter is being displaced and `reconstructed` at the reappearance point or whether it is simply being bent (on a quantum level, perhaps) from the `entrance` of one portal to the `exit` of the other.

To my thinking the bending action seems more likely. Even just the type of functions that a portal collision facilitates (that is, the inserted object making contact with itself mid-portal) are reminiscent of a bending action.

Though this in no way equates directly to a quantum bent of the matter, just think about what would happen if you sat on the ground next to a floor "entrance" portal and hung your legs down through it. Assuming its corresponding "exit" portal was on a ceiling low enough for you to reach your legs while remaining seated, you could reach up and scratch your own foot. The only other way for you to do this with your hand, absent the portal? Bending over.

When bending over, the possibilities are endless - especially if exit points are being confused with entrances.

Student_Law, think less stargate more portal.

The difference is it`s happening instantaneously in portal you can have half your body on one side and the other half on the other side and still be connected. If there is no room on the other side of the portal, nothing can be disintegrated and reintegrated instantaneously. Therefore no movement occurs.

There is no event horizon, just the bottom and the top of the room.

I partially agree with Klamz:

A) is a bit tricky, beacause in order to achieve portal function, the steel rod has to be deteriorated and re-assembled at an atomic level, at the speed of light. When you weld the ends together while in the portal, you have a whole steel rod, like you have always had, but at this moment the steel rod is being cut byt the portal, wherever you hold it, instead of the before-welding situation where you actually have two pieces of steel rods. But gravity is still a factor, and as long as the bottom portal will deteriorate anything put into it, and gravitation will keep putting the rod down and down, you will get an effect where the rod is "falling" - but now it falls as a "whole" piece, and you will see the joint from the welding pass through the portals every now and then. (At normal gravitational speed, adjusted to the weight of the rod)

I`ve seen this poo so many times, it`s annoying now. I`d guess this would happen:

A) It would fall, gravity is pushing down, and nothing is pushing up.

B) The rod would be crushed.

C) The rod would be cut when the portals close to relocate.

And I`ll say again since people keep posting the opposite.

In A, It would not fall down through the blue portal and come out of the orange, the reason to this is because there is no room for it to fall or even move downward. Everyone needs to remember their is no extra space created in a portal it just moves things from 1 area to another.

Imagine stacking bricks between the 2 portals, 1 on top and 1 on bottom. Assume you have room for only 1 more brick. You lift the bricks up to the top portal and they come out of the bottom, because it has space to move. As your hold it you slide the last brick in and it holds it in place and no longer has the room to move, it`s stuck between the top and the bottom as if the portals weren`t even there. Gravity can`t make anything move if there is no room for movement.

There are actually very few areas using moving portals, I can think of but 1 and that`s to cut the neurotoxin tubes. Every other portal you put on a wall and then it moves it disappears.

Perhaps a portal requires conservation of momentum to maintain its stability. In any case moving portals only works with lasers and not solid objects... test it if you don`t believe me.

Thus example B could never happen as the portal would disappear or it wouldn`t be physically able to move due to portal restrictions.

you`re not thinking this portals

in the last part, since you welded the rod and essentially made a loop, the rod would appear bent connecting the 2 portals (imagine a ring and we`re only seeing 25% of it); no, the rod isn`t any longer, I was merely giving a visual idea into your mind.

but why would you solder 2 ends of a metal rod together? why wouldn`t you weld them?

Not true. there are more than a few occasions where you can attach a portal to a hidden panel area that would not only move out once the button is pressed but would angle differently.

The rod is always a fixed length, all that is happening is that the other end of the rod is being displaced.

Therefore:

(a) Will accelerate.
(b) The bar would act like very similar to a regular support beam. If it is compressed then the beam would bend and buckle.
(c) Again... finite length... so if the original bar is 2m long there would simply be a 2m long bar extending out of the blue and nothing out of the orange.

A.) The rod will not move.
Explanation: The only space is the space between the portals, theirs no extra space `inside` a portal, that`s just the space between the portals again. If their was even a micrometer of space between the connection then it would fall however, by attaching it to itself it is stopping itself from falling, like putting your had between them to catch something stops it from falling. If theirs no area for it to move, it cannot move.

B.) Portals don`t move, don`t be stupid, learn your portal physics.

C.) The rod will fall into the blue portal due to gravity and shoot slowly out of of the orange portal in a downward direction as gravity starts pulling on it. (So you know portal destruction and recreation happen simultaneously)

Again, there is no space inside the portal only the space between. It`s not a pocket universe.

Use your brain.

"(a) The rod falls.
(b) The portals are together and you can`t see the rod.
(c) The rod snaps as the orange portal disappears (the other end is suddenly cut off by the solid surface that has just shown up), then as the orange portal reappears, the other end of the rod becomes visible through the opening."

A correction for b:

b) The rod compresses lengthwise and bends or snaps, just as if it were squeezed between two solid walls (think trash compactor scene in Star Wars).

the answer to B is simple when the platforms that the portals are placed on move the portal on that platform disappears, and yes that means the steel rod gets cut in half

@scottserious - From what I understand it might cancel itself out. For the same reason you cannot shoot a portal through a portal, I believe once you put the panel with the blue portal into the orange, the portals would collapse causing the panels to be intertwined. I`d like to see what happens if you are halfway through the portal and THEN do that.

Assuming a `classic` model of a portal:

A) It accelerates at as close to g as possible given the limitations of air resistance arising from turbulence and presuming that it does not touch the edge of the portal.

B) Why would the portal move? Unless it is suspended in a physical device, in which case it would clatter onto the first.

C) If you moved one portal out of alignment then the rod could touch the edge of the portal. If the move is instantaneous, the rod would be severed.

a) Moves at constant speed. The joint will pass regularly, at a normal, gravitational speed.

b)The length of the metal rod is constant and not "flexible" in any way. If you try and push or move the orange portal, it will be stopped by the metal rod. The portal may fall to the side, but then it will hang by the upper end of the rod, or simply fall off causing the rod to separate from the portal.

c) In the example depicted in drawinc c, the metal rod would either crash into itself or simply just pass it`s own original angle, possibly causing the metal rod to fall out of the portal "circulation"
