You would crush yourself.

you would literally be being crushed by you

[–]stratus1469 8 points9 points ago

It would be like a massive row of yourself crushing each other yourself with the force of the two walls.

[–]XypherFTW 8 points9 points ago

Which could be anywhere from feather force to the force of a fucking black hole's gravity

[–]TheMorphling -4 points-3 points ago

Expect when the pillars move towards you the portals will disappear and you will be just be crushed, nothing to do with portals

[–]Kromgar 2 points3 points ago

Moving portals has been shown in portal 2 to occur so you lose

[–]bboy799 1 point2 points ago

Wait a second... Every portal theory has been proved right. The laser part.

[–]Hamakua 4 points5 points ago

You would squish yourself is the real answer.

[–]GIJew392 6 points7 points ago

You would literally collapse into yourself until you're what's stopping the portals from touching each other. If you think about it, the first thing your head would hit is your feet, if you're prone or supine. From there, you would end up getting crushed from infinite "you's" being pushed against yourself with the force of the pistons pushing the portals.

TLDR; You're gonna have a bad time.

[–]ductaperecorder 4 points5 points ago

I'm pretty sure you would just be compressed into infinity...

[–]Thorvalde 4 points5 points ago

compressed into infity by YOU

[–]ductaperecorder 1 point2 points ago

Exactly

[–]Watchdog84[!] 1 point2 points ago

So..... you become a small black hole is what your saying?

[–]ductaperecorder 1 point2 points ago

More or less, yeah

[–]galaxies 7 points8 points ago

Portals disappear when the wall they are on moves, so you would be crushed without portals having anything to do with it.

[–]barter_ 1 point2 points ago

Not on Portal 2 they don't, that part where you use laser to cut the wires the portal is moving.

[–]Aysaar 5 points6 points ago

that is sideways, if it moves forwards they disappear, even if they didn't you would crush yourself

[–]Jayalexyoung 4 points5 points ago

Portals Can't be placed on moving surfaces. sorry.

[–]FirmerFilly 1 point2 points ago

You wouldn't survive. You're just switching which wall is on the left and right, so you're still going to get crushed.

[–]XeroG 3 points4 points ago

You would die.

Think about it like this. If you were in a narrow corridor with a portal on each side of you, what happens when you half of your body in one? Well you stop taking up x amount of room on one side of the hallway and begin to take it up on the other. When the portals get so close that putting your hand in one makes it come out the other and consequently back into the other one, you increase the amount of portals you travel through just to put your hand in the hallway. As the distance between portals approaches zero, you have to go through infinitely more portals just for putting your hand in one of them. My mind doesn't one to think about what would happen when the distance does equal zero, but it could be one of two possibilities:

1, you body heat up so much from the energy required to exist in som many places at once that it evaporates. 2, one portal closes upon touching the other, which resembles the game's mechanics more than option one.

[–]niro88 3 points4 points ago

The portals would dissapear when the walls are moving

[–]clb92 0 points1 point ago

May I redirect you to Portal 2, please?

[–]Nejustinas[S] 2 points3 points ago

I am not sure where i should be posting this question...

[–]UncleGooch 0 points1 point ago

This seems the best place.

[–]Bugsi 4 points5 points ago

The only way I can get my head round it is by knowing that I can't put portals on moving surfaces. My brain explodes otherwise and I can't go through that again.

[–]ReaperChicken 12 points13 points ago

There is a level in Portal 2 where you put a portal on a moving surface in order to use a laser to cut through some pipes.

[–]GreenSpleen6 4 points5 points ago

See, the rule is that portals can move on the 2d plane on which they rest. They cant move forward or backward, preventing paradoxes. Above scenario is impossible.

[–]clb92 0 points1 point ago

[–]GreenSpleen6 0 points1 point ago

For that to be possible, the orange portal must be smaller than the blue. Since all portals are exactly the same size, the platform on which the orange portal lies must be bigger than the blue portal, so it simply wont fit.

[–]GreenSpleen6 0 points1 point ago

Fuck, forgot about that. Well, i'd have to assume that when one portal starts to pass through the other, one or both of them would cancel out, via the same mechanic that doesnt allow you to shoot a portal through another portal.

[–]clb92 0 points1 point ago

Maybe. But since portals are still fictional, we might never find out...

[–]MaserPhaser 3 points4 points ago

Valve coded the game so that portals dissipate after the surface they are on moves so they could avoid this paradox

[–]earthenfield 2 points3 points ago

Except for that one level in Portal 2 that disregards that rule entirely.

[–]PTRiot 0 points1 point ago

Can you post a video or something to prove this? I can't remember this off the top of my head and I'm not sure it's the same thing as this.

[–]earthenfield 4 points5 points ago

Sure can.

edit: I should add that I don't have a problem with moving portals, and I think they could be used creatively for some really challenging and interesting levels.

[–]PTRiot 1 point2 points ago

Thank you sir. I think I can see a problem in this paradox then.

[–]GreenSpleen6 2 points3 points ago

They can only move sideways or up and down, on a 2d plane. They cant move forward or back, like OP's demo.

[–]Hammers_n_Strings 1 point2 points ago

But they're still only moving through the plane in which they exist. In OP's example, their motion is orthogonal to that plane, which is not possible.

[–]earthenfield 0 points1 point ago

I'm not going to pretend to be smart enough to know what "orthogonal" means, but I'm not sure that holds up. It depends on how Portals are supposed to maintain their link. Sure, they're only moving parallel to their plane relative to the planet, but the planet is still moving. Maybe it maintains its position in the gravity well somehow, but then the portal on the moon would be introducing the gravity well and movement of a new celestial body into that, so its hard to see how that could work.

[–]Hammers_n_Strings 0 points1 point ago

"Orthogonal" is a higher-dimensional generalization of "perpendicular." In the game, if you put a portal on a surface that forces the portal to move orthogonally to the plane on which the portal exists, it dissipates. That's part of how it works in-game and I would assume that we're following those rules.

I get what you're saying about the earth and moon moving with respect to each other, but maybe there are certain thresholds (speed, distance, etc) that have to be breached for a portal to dissipate with this kind of motion. In the original game, the rule for orthogonal movement dissipation holds, but Portal 2 changed a few things with the whole moon thing.

I don't know how gravity wells fit into this, though.

[–]GreenSpleen6 1 point2 points ago

They can only move sideways, on the 2d plane. Never forward or back.

[–]inverseion 0 points1 point ago

it isn't on the moving surfaces, it's on the walls they impact. the other end of the portal is still in an open space.

[–]Knomez 1 point2 points ago

I am pretty sure you would be crushed by yourself.

Lets take a person out of this and make it a 1 meter cube because it makes it more regular. If a 1 meter cube is place in a 1 meter hallway with portals on either side it takes up the entire hallway (by width) If you move the cube .5 meters in either direction you now have .5m of the cube taking up one side and .5m of the cube taking up the other. The width of the hall is still taken up.

When you move a portal you are essentially shrinking the hallway. Unlike in the real world where the walls would be exerting the force it would be the left side pressing on the right side. The result would however be the same.

The more interesting question to me is would the two walls moving the portals register the resistance of the cube to being compacted? Or to take it to an extreme, Would the portals (and the walls holding them) be able to come together if an un-compressible cube were placed between them?

[–]Cyphafrost 0 points1 point ago

Well, when you shoot a blue portal onto an already placed orange, it fizzles out. I would think when they touch, they both fizzle, and you are crushed.

[–]laur7620 0 points1 point ago

Think about it like this... If you have a portal at one side of the room and another at the exact same spot on the opposite side of the room, the amount of space between the two is ample enough and you don't get crushed. When you move them that close together the space isn't large enough to allow room for your body. It seems more paradoxical than it is. The problem is that we are focusing on the fact that the portals are moving us back and forth so we think that there is some kind of philosophical answer, which is understandable, and there would be a philosophical answer to what would be crushing the body. Because the portal itself is unable to crush you because the surface of it transports you what would be crushing you would be the small space in between the two. There is too little room for all the matter your body is made of. Your body wouldn't be able to crush you either because it would just push it against the portal which then transports you. It is not something pushing on you and crushing you but instead the amount of space not being adequate.

A chiropractor.

[–]kostiak 0 points1 point ago

One example of the very many that demonstrate that the portal gun can't exist in real life because it breaks the laws of physics.

[–]isah18 0 points1 point ago

you'll split in half

[–]HTRK74JR -1 points0 points ago

[–]PwndYooSucka 0 points1 point ago

SIMPLE: You wouldn't even die, because portals do not stay on moving objects. Therefore, you couldn't push them together.

[–]nemotastic 2 points3 points ago

You would most certainly die. The portals would disappear and you would be crushed by two very large pistons.

[–]Church1092 1 point2 points ago

Portals dissipate on moving structures. This has been proven in both games.

Please do not try to misuse our product

[–]BaronLaladedo 0 points1 point ago

The troll face dosen't really belong there anymore.

[–]black4ugust 1 point2 points ago

I think a lot of people are disregarding what would happen if two portals even touched face to face. My guess is what happens with you put a portable hole into a bag of holding.

[–]XxCrazypoi5xX 1 point2 points ago

The portals would disappear thanks to the game mechanics in which if placed on a moving surface they vanish.

[–]RhinoK43 0 points1 point ago

It would be a never ending tunnel.

[–]wick3Dwick 0 points1 point ago

its easy... you'll implode

[–]Tend_to_agree 0 points1 point ago

Pretty sure it's been answered.

[–]crymsonnite 0 points1 point ago

It depends on if they both move or not, portals can't be on moving surfaces

[–]crhone 0 points1 point ago

considering the neurotoxin chamber's portal physics, you would die by being crushed by yourself. sounds fun, doesn't it?

[–]GreenSpleen6 0 points1 point ago

Dead, the only difference between this and being crushed between two normal pistons is that the walls will be made of you instead of metal.

[–]itsme0 1 point2 points ago

No mater how many ties I look, I don't see you standing on a floor, therefor you keep falling and the walls close. The portals probably disappear at that point, or at least might as well have.

[–]Goodrita 0 points1 point ago

It's 6 am in the morning, you're making my fucking brain hurt.

[–]HawkyGaming 0 points1 point ago

Either you would crush yourself or you meet Gaben in the Vacuum of time and space while he spins around with a copy of Half Life 3 in his hands.

[–]Dangerous_Theory 0 points1 point ago

This just made me think: what if you were standing in a narrow corridor with portals either side of you and you stretched your left and right arms out through the portal until they were reaching each other and held them together. Is that even possible? The sensation would be fucking weird, right?

[–]JeeWillakers 0 points1 point ago

I came to the conclusion that if both panels are moving together, and are unstoppable, you would essentially be crushed to death, and whatever atoms are in between the portals reach some sort of singularity.

[–]gu3sswhoiam121 0 points1 point ago

You would die cause the portals vanish if the surface they are on moves.

[–]Asiansensationz 0 points1 point ago

Well, I always wanted experience singularity

[–]ItzMcShagNasty 0 points1 point ago

You would crush yourself.

[–]ferjero989 1 point2 points ago

first. there is no space/time in the portal, only whatever is in the other end of the portal. by that logic, there isnt any real space inside. so you will be crushed by yourself.

[–]darklord94 0 points1 point ago

You will still die because it will the same way without the portals just you get some more finger space

[–]tier22 0 points1 point ago

you would be in an infinite tube made of the inside of the concrete.

[–]Godzilla2y 0 points1 point ago

No, you would not. Portals can only exist on stationary objects. As soon as the two pillars begin moving towards each other, they would disappear.

[–]BladedDingo 0 points1 point ago

Assuming we're talking about suspending the rules of the game and allow the portals to move with the platform forward, I assume the result would be not unlike what happens when someone comes through a Stargate. If something is blocking the event horizon of the portal by a fraction of a nanometer the object traveling through would be destroyed because it does not have the space to reappear.

if one portal blocks the other portal, it would destroy what ever was inbetween because there is no place for it to re-appear. If the pistons retracted, your have two shiney portals and a bunch of used to be you atoms floating around.

[–]ZellnuuEon 0 points1 point ago

Movement breaks portals. You are crushed by the metal.

[–]ScorchedPanda 1 point2 points ago

Portals cannot move through physical space. you would be crushed between the two surfaces.

[–]coltalain -2 points-1 points ago

You would survive I think but you wouldn't go anywhere it would simultaneously be in both portals till the wall things were moved just a thought of course

[–]Nejustinas[S] 0 points1 point ago

Seems like every one here (well almost i think) has the right answers.

Here is mine to clarify: You would get crushed by yourself yes. It is like there were no portals on the pistons. Except that something interesting happens. Since portals have no gap between each other meaning if you put one inside of each other (that is another mindfuck) it would just reflect back what is being put in it. Or depending which way it is pointed the thing you put in will go through like nothing is there. Lets just say there is no space between them like other portals show if you turn them off while traveling you get stuck in some "space time of traveling". They just make it like a tunnel.

So if thinking how the can you squish yourself? Well if you tie a rope and one end is from one portal and the other one is from the other, they have equal force and they cancel each other out by pulling on each other (if you don't get it just search "portal rope" in google in images) There are portals A and B and so A portal is say your feet coming IN the portal A and the feet are now coming OUT of portal B so you are pushing yourself in the back, but with the equal forces, meaning you don't go anywhere, you just feel something pushing your back. So when the gap between the portals A and B is very small like 1millimeter then your body is not squishing you because there is only that much space to fit in. It would be the same as pistons squishing you except that you are actually killing yourself by your own mass.

When there is NO gap between the portals then there is no space but there is mass. You become a black hole possibly but there is no space sooooo.... you kind of um... don't exist? I mean there is no space for you but you have the mass and force? As some guy stated that your density is now infinity. Image your own atoms are being squished by their own mass.

TL;DR: You get squished by yourself and you become a black hole or you are stuck in some dimension where you have mass and force but have no space for it.

Hope people don't get mad about my bad grammar :). Ask if you don't get one part. This really can twist your mind. IT REALLY CAN.

And thank you for your feedback.
