Wouldn't you crush yourself?

Edit: I feel dirty for getting karma for this. I'm pretty sure I read this answer on 4chan.

I'M NOT GIVING IT BACK THOUGH AND YOU CAN'T MAKE ME.

[–]Fearlessleader85 159 points160 points ago

Yes, the portals have no depth.

Think of it this way, you move to where you're half way through, so half of you is poking out each portal, then you push the two portals together. Your two halves would crush each other with perfectly matched forces.

[–]busfahrer 4 points5 points ago

I understand the part about crushing yourself.

What I'm wondering about now is this:

Let's say one of the portals has been put there "upside down" in relation to the other, i.e. something that goes into the bottom part of the blue portal would come out of the top part of the orange one.

Now let's say you do the same experiment with something small that doesn't interfere with itself. What would happen?

[–]Fearlessleader85 10 points11 points ago

Interesting. You'd certainly get a good, close look at your feet. I'll have to think some more. You'd certainly die, but i think you might end up looking like a strawberry swirl and i believe you would spin, accelerating towards the speed of light, because there would be unpaired forces.

At this point, we're breaking so many laws of physics it's difficult to say.

[–]busfahrer 5 points6 points ago

I think the answer is that for the first time, the object avoids itself, but gets immediately put into the portal again, so that it now comes out in the position that it was originally put into, therefore crushing itself (all within the space of 0)

[–]Fearlessleader85 2 points3 points ago

Well, when the two portals are completely pressed together, then all matter would have to exist on a two dimensional plane, which means no volume, which means infinite density, which means fuck reality, so you probably couldn't actually squish them to that point no matter how hard you pressed.

But AS you squish them together, you get unpaired forces, and i think it would potentially cause some spinning.

[–]AbrahamVanHelsing 2 points3 points ago

No, you don't get unpaired forces. Imagine that cube again. It (maybe simultaneously, maybe asynchronously) enters the bottom of the orange portal (coming out the top of the blue) and the bottom of the blue portal (coming out the top of the orange. These two parts of the cube ALWAYS come out directly across from each other.

Gaze in hopeless adoration at my epic MS Paint skills!

[–]Tiktalik 0 points1 point ago

Portals won't stay on moving surfaces.

[–]Fearlessleader85 0 points1 point ago

You are correct.

[–]Dyssomniac 1 point2 points ago

infinite density

Like right before the big bang, huh...

CHECKMATE, THEISTS. WITH PORTALS.

[–]Fearlessleader85 1 point2 points ago

Then you create a universe inside the portals with a total volume of zero. Excited? You can bet on my erection i am.

[–]Linksysruler 1 point2 points ago

So you effectively get crushed into a Kerr Black Hole?

Well damn, I'm surprised Cave Johnson never tried testing this.

[–]Fearlessleader85 0 points1 point ago

Well, since you can't move portals, it's impossible.

[–]king_of_the_universe 1 point2 points ago

I think the same divided by two would happen.

Imagine: If there's a cube at the bottom, and it begins just inside the space between the portals (so it doesn't intersect with portal 1), but it ends 1% of its size inside portal 2.

This little piece would now be above the cube, coming out of portal 1 with which the cube does not intersect.

If we move the portals closer, so that 50% of the cube reaches into portal 2, 50% of the cube will be coming out of portal 1 above the "original" cube. This means that every little bit more that you move the portals closer would mean that the "second" cube has to come in through portal 1 again, but at the bottom, where it collides with the "original" cube.

So, the space necessary to remain unsquished could be half as it would have to be without the inversion trick.

Regarding the force:

I believe there might indeed be something like an "infinite" force involved, similar to the zero-point-energy of the gravity gun in Half Life II.

The power does not come from the moving pistons but from the spacetime disruption that the portals effect. The pistons will never feel any resistance, because they are not touched. The portals, which are attached to the pistons, are also not touched, so there's no force feedback.

I believe that it would just be some supernatural spacetime-grows-smaller experience for the cube: The universe is too small, and the cube plain simply is fucked.

[–]AbrahamVanHelsing 0 points1 point ago

I was going to post a rebuttal of the "portals don't feel a resistance" part of your post on the grounds that you could obtain free energy by crushing things.

Then I realized we're talking about portals.

Plus, you can obtain free energy from them in other ways, anyway. Like the portal on ceiling / portal on floor trick.

Ninja Edit: I also included a diagram in another post above. It illustrates basically what you described, except assuming the cube is fairly well-centered between the portals. Here's a link. And here's the diagram

[–]totally_mokes 0 points1 point ago

A high-pressure egg whisk type of situation ensues. This kills the body.

[–]Zap-Brannigan 2 points3 points ago

that depends on the forces exerted by the crusher thingies actually (I think)

[–]Fearlessleader85 1 point2 points ago

Yes, but i'm assuming sufficient force is used to squish you.

[–]DeepDuh 0 points1 point ago

Always a good assumption to make..

      FTFY

      [–]Fearlessleader85 25 points26 points ago

      No, because it's a self correcting problem. It's like how an ice cube floating in a glass of water always has exactly the same ratio of ice under water vs ice above the surface, even as it melts. The offset dictates the forces in action.

      Think of it like a mirror. No matter where you touch a mirror, you can never miss your reflection. With the portals, you could angle yourself to avoid running into yourself for a while, but as the portals get closer and closer together, you end up broken up into more and more "real pieces", eventually reaching such fine slices that you would squirt out around the edges, squishing yourself against yourself.

      [–]Hamakua 2 points3 points ago

      Your description reminds me of spaghetification.

      [–]Riotmaker 1 point2 points ago

      Why doesn't your analogy work for icebergs?

      [–]Mormoran 2 points3 points ago

      I think you're thinking of mass or volume. He says only ratio, so it could mean 10% of the ice is above and 90% below, even if it's ice or an iceberg, and the ratio is individual to each piece of ice or each iceberg so each case is different.

      [–]Fearlessleader85 1 point2 points ago

      Yes, it depends on the density of the ice in question, which is not necessarily constant.

      [–]AbrahamVanHelsing 0 points1 point ago

      Also on the density of the water. You tend to float ice cubes in tap water or similar, which is fresh. Icebergs are more likely in ocean water, which is denser due to the salt.

      The density of tap water is 1000 g/mL, ocean water is ~1030 g/mL.

      [–]Riotmaker 0 points1 point ago

      Got it, thanks for clarifying for the slow of mind.

      [–]Fearlessleader85 1 point2 points ago

      It does. If the ice doesn't have any bubbles, then as it melts, the ratio between the ice above water and below water will be identical and determined by the density of the ice. This is because the exact mass of the entire iceberg is being displaced in water. This is also why an ice cube melting in a glass of water leaves the water level exactly the same. The ice is less dense, but when it melts, it becomes the exact same density as the water, so it exactly replaces the volume lost by the melting ice.

      [–]Zap-Brannigan 4 points5 points ago

      it would be like being crushed by those metal plates, but if they were made of human. there would still be a bit of space in between them because it would be hard to push the plates together.

        I drew a diagram for you.

        Basically, you're getting crushed by an infinite number of yourselves. As the two portals move closer together, they are compressing a finite amount of matter (you) into an infinitely small space.

        [–]DrXenu 7 points8 points ago

        it would appear to be an infinate number of yourselves... but in reality you are just getting crushed by the other side of your body. Not saying you are really wrong, but the description seems a little off.

        [–]yammez 2 points3 points ago

        Yeah, essentially this is just switching the surfaces' places.

        [–]Vouk73 39 points40 points ago

        I always assumed that they're 2 dimensional.

        There is no twilight zone, part of you is in the orange zone, part of you is in the blue zone. Nothing is between.

        [–]DrXenu 0 points1 point ago

        the portals arent really any dimensions... it is like if you were walking from one side of the room to another. basically given the setup of this logic question you would simply crush against yourself and thats it. The extra syrup that was your body would simply fall out of the sides until you are nothing but a puddle... bones and all.

          I can't imagine that thickness would matter, seeing as whereever you enter in blue, you exit from orange, which would just push back on your original, un-portalfied self.

          [–]julielc 8 points9 points ago

          Sorry to burst your bubble, but portals cannot move relative to each other, the portal would break and you would be crushed normally.

          [–]Technospider 13 points14 points ago

          Actually in one portion of portal 2 you are required to place a portal on a moving surface. When you need to cause that big tank thing to implode.

          [–]nikomo 2 points3 points ago

          I got stuck on that part for a couple of minutes because of Valve breaking the Portal-rules.

          [–]Provider92 2 points3 points ago

          But they never move forward and back, only to the side of the portal. Every time a portal has moved in or out on a surface, it has disappeared.

            Although I recognize that the original question is about an impossible scenario to begin with, I hate when people give an answer to these sorts of questions that is based on what was obviously just a technical limitation of Portal's engine. If we're going to think about an imaginary world where portals exist, let's put aside the limitations of the video game for the sake of a more interesting thought experiment.

              From the picture, you are unable to tell if there is a solid wall behind the portals. It could be completely open, allowing him to theoretically fit right in there. He'd die though :P

              but yourself is copied infinitely and there are no walls on either side of any copy to push against, so i think there would just be you standing next to an infinite amount of copies of yourself for an infinite distance in blackness

              Sort of. Two portals can't overlap so as soon as they're pressed together they'd cancel out and you'd be killed.

                B: plop down on the ground

                The problem is: Newtonian physics is based on transferring momentem relative to the object you're interacting with. For example If you are going (very fast) 60.001 meters per second and you hit into a object moving at 60 meters per second your net impact would be just like hitting a wall going .001 meters per second or .06 meters per hour.

                  This technically shouldn't be a problem for the game engine, as a portal on a rotating platform would still avoid having to calculate for relativity. Dr_professional pointed out this as the most likely reason they have this rule, and I'm very inclined to agree with him

                    You would implode into yourself. For the portals to work, you need exit room, but if the Portals were put up against each other like that, you would have no room, and crush yourself with the left and right. Now heres a better question, i think What happens if you throw a piece of white board that has the blue portal INTO the orange portal?

                      It simply wont go through. Because the blue portal would come out of itself, it couldnt go more than halfway through the orange because its widht would increase.

                        yeah definitely some self crushing going on here, in fact if you were standing facing the portal your face would be smashed into the back of your head into it was paper thin

                          None of these ever made sense to me, as soon as either surface moves the portal would dispel just like in the game.

                          But they made an exception in Portal 2 with the lasers that cut the neurotoxin tubes. The portals are moving (and its the only time they do, try to go through and i think the game crash.. seen a vid on it some time ago)

                          [–]TheIndigoSky 8 points9 points ago

                          Do those Portals move laterally (perpendicular to the normal of the portal surface)? I'm pretty sure the canon restriction on portal movement is that they cannot move "forward" or "backward".

                          [–]Twad_feu 0 points1 point ago

                          Nope, it was a vertical movement if i recall correctly.

                          Are you sure? When you cut off the big neurotoxin pipes, and implode the big tank, the portals are moving, and not stationary? Or do i misunderstand you?

                            XKCD had a fun thread on a very similar experiment that assumed that you would be able to place portals on moving objects.

                            They explain how the portals would never be able to touch since the mass between them would exert infinite energy pushing outwards as well as what happens if you put a portal in a portal, etc.

                            Pretty sure you would be crushed. Through either end of the portal is a solid wall. Even though you are jumping between the portals rapidly I'd say there would still be the physical wall. I don't know, just my two cents.

                            Say you're standing directly in between the pistons and facing a portal (and for the sake of argument let's assume a portal can stay constant while in motion). As they close in on, your front half and back half would collide as they simultaneously enter the same part of the portal and be forced together. Essentially your body would squish itself between the two portals and exist within the space between the two pistons.

                            Holy shit. Wouldn't you be turned 2-dimensional, since any z-coordinate (in/out of the portal) not on the portal itself will simply get warped through. Then again, the process of every single plane in your body attempting to take up the same space would just crush you into a 2 dimensional blob of infinite area.

                            you would crush yourself, but the possibility of it being hilarious increases. You could step on your own head, shove your head up your ass, etc. Imagine 2 small rooms with a hole connecting them. The walls opposite of the hole move in towards each other until they touch. That would be an equivalent situation but with less fun, physics-defying action of aperture science.

                            You wouldn't survive, because as the portals move together, the mater at the event horizon would re-materialize inside an existing part of your body.

                            There needs to be a consortium on they laws of portals. It'd start something like this:

                            -Portals require vast amounts of energy to move matter, related to the mass and distance the object moved, but far less efficient.

                            -Portals cannot move relative to each other, otherwise they collapse.

                            -No girls are allowed in the portal!

                            You can't place portals on moving surfaces, if you attempt to perform this in Portal 1 or 2, you get flung across the room.

                            They create miniaturized dimensions, which can't interlope.

                            The question is where would you go, not whether or not the physics are possible. My best guess would be that you would be in an infinite loop with no escape until the crushers moved. You would not be in space as we know it, you would be in a sub-space. Locked in suspension until you are released from your looping prison.

                            Portals really really really can't move opposite directions.

                            They can move the same direction (more or less) by being on Earth as it spins, but opposite directions are nonsensical, as you are basically moving the entire universe.

                            There have been discussions of this already.

                            your left side would crush your right side ? or the other way around.

                            Portals cant stay on moving platforms so this couldn't exist.

                            This is why portals can't exist on moving surfaces.

                            You will crush your self.

                            You would be crushed, portals cannot stay on moving surfaces, therefore as soon as said surfaces move the portals will disappear and you will be crushed.

                            Yeah that guy should not be smiling, he is about to die what I imagine to be an extremely painful death

                            Possibly crushed into a singularity, only to explode with the force of a trillion suns. The other scenario is the feedback would destroy the prtals and what is left of you will be smushed between two metal plates

                            What a coincidence. I was wondering about this last night before i went to sleep.

                            Portals placed in moving surfaces tends to disappear then the surface starts to move. You would die crushed because there wouldn't be any portals.

                            I see I am obviously too late to say you'd crush yourself.

                            didn't understand any of the physics related portion of these comment threads but had to add: "now you are thinking with portals.."

                            [–]TheoPepper 0 points1 point ago

                            I don't know if anyone has said it yet (can't be bothered to read all the comments) but in the game, when there is a portal on a surface and the surface moves, the portal disappears. So you would just be crushed by two panels.

                            You would be crushed by yourself.
