UPDATE: So Austin from THE SCIENCE actually watched the video and said he liked it! I had the pleasure of talking with him and my expectations were exceeded. He took the critique really well and he was super chill about all of it. I'm so glad something productive came from this video! Also, check out the Science of the Wunderwaffe DG-2 from COD Zombies here: ua-cam.com/video/S92ti5LUFxA/v-deo.html Comment which science videos you would like to see in the future!
It would be really cool to see you cooperate with him in a future video. And please let it be about this franchise(maybe about the combustable lemon?).
As a good scientist, I will spam my objections into any comment with less than ten replies. 1. The bright side of the moon that chell sent a portal to is not cold because the sun broils it to 250°, and 2. The earth moves so his idea for a portal is literally impossible
E=MC²=V/s² Where V is equal to velocity divided by that of space of S², which equals that of the ultimate amount of energy to that of matter that is equal to be transferred to based on the distance that is allowed from the amount of energy that is first received. You would need at least 5 miniaturized fusion devices to be able to give enough energy for it to be possible. Which is equal to 500000 mega, jewels of energy and 500000 V of that energy to allow for the amount of time differential to allow that of a movement of the portal on the first start while the secondary portal is at the stationary Designation.
Same, but what is double weird is that I thought this guy only did jojo memes. I have been subscribed for years to this person, and had no Idea they did stuff like this.
This is a developer command in Portal 2 and afterwards exclusively. This is only to make a good puzzle element. I do not believe that it was fully meant to disprove someone who literally has a masters degree.
@@itstimeforMario64PLAYER it's only used in one puzzle because portals are technically complicated and moving portals cause issues that dont really pop up in a puzzle where you're not able to traverse or send objects through the portals. the fact that they can't move in most of the game doesn't mean you don't literally see first hand how the portals are moving. saying portals can't move is to completely ignore both the important neurotoxin sequence and the last portal you shoot in the game, at the moon, which is undeniably moving relative to the earth's surface. portals being unable to move makes zero sense if you wanna apply any kind of real world logic. this whole video makes very little sense when you look past the 10 dollar words and parading of credentials
i think it has something to do with the conditions in which the portals are created, for example if a portal is created in a moving surface and the movement of that surface keeps stable it would still link both portals if the conditions mantain the same, same aplies to the angle the portal is created in, we never saw a portal move in the same direction the the "opening" is, that would be an answer to the neurotoxin sequence
Let us assume that portals can be created on moving surfaces. That rule is never explicitly stated in game, at least not that I know of, and the neurotoxin puzzle proves it is possible. Whether it is only possible under certain conditions or not, like @foxhdn233 said, it is a fact. With that said, I see no reason that option A of the portal paradox would not be the correct answer. To quote GLaDOS "You appear to understand how a portal affects forward momentum, or to be more precise, how it does NOT."
This year I'll get my Master's Degree in Physics. I see a few problems with your logic: 1. Tunneling does not explain why teleportation in the game is instantaneous. In quantum tunneling, the wave fuction takes time to propagate through the barrier. Why am I so sure that in-game this phenomenon is instantaneous? Just watch the cutscene when you defeat GLaDOS, I don't want to make spoilers. 2. You correctly explained the lose of momentum (energy) when passing through the barrier. But that does not explain the change in direction of momentum of the outgoing particle. It could be possible if the potential barrier is not spacially homogeneous but that cannot be guaranteed for every wall you choose to place a portal on. 3. Not only the direction of momentum changes, but also the position of the outgoing particle does. The only explanation I could come up with is that none of the white surfaces in the game are actually superconductors. Instead, they become superconductors ONLY when a portal is placed on them (suppose that it is possible for the sake of our sanity). That way, the chances of tunnelling to the other superconductor far away (the other portal) are much greater than tunneling to a random wall in the room. This could be a flawed statement since in-game 100% of times the object passing through the portal appears in the other portal instead of a random wall (not to mention that also 100% of particles composing the object tunnel to the same wall) I hope I made the statements clear and I'm open to discuss this with anyone, even without a Physics background.
I'm not sure if it is instantaneous. When you shoot the Moon with the portal gun in the finale of Portal 2, it takes a couple of seconds between when you fire and when the portal actually opens. That fits with the effect travelling at the speed of light.
@@Roxor128 That is not related to what I said. I didn't mean the time between shooting and portal appearing. I was talking about the time between entering a portal and appearing on the other side. When you shoot the moon and things start to go through the portal, they appear on the Moon instantaneously, including you.
To be fair, on the first point, Aperture has already done other stuff that should break laws of physics. We could just excuse it with "Aperture has godlike technology"
@@kiwenmanisuno I see. And that would be truly GODlike since it breaks General Relativity, making it possible for information to travel faster than the speed of light.

@@pizzainc.1465 Tell me then, how scientists can cool something to almost absolute zero, with two billionths of a degree away from reaching it. And the only thing that makes it unattainable is the hardware. How can something on a moving earth reach such a temperature?
@@pizzainc.1465 Every other physical particle/wave that we know exists and is in here obeys the laws of gravity and momentum, so they'd still have the correct momentum because of where they are being created.
Why does this ACTUAL PARTICLE SCIENTIST that ALMOST HAS A MASTER'S DEGREE get so shafted by the algorithm?? Like wtf youtube! You're missing out on making one of the greatest youtubers of this genre a popular creator.
15:43 "Spectacular. You appear to understand how a portal affects forward momentum, or to be more precise, how it does not. Momentum, a function of mass and velocity, is conserved between portals. In layman’s terms; speedy thing goes in, speedy thing comes out." -GLaDOS, Portal 1 (Test Chamber 10)
yeah it's kinda silly because portals are not frozen in space because they would be constantly moving, so trying to say they CAN'T move only works if the portal is in space with zero motion.
@@objectionablycurious This is kind of failing to understand what temperature is. Temperature is not the same as kinetic energy, temperature is a measure of the average kinetic energy of individual particles.
@@disappointedcucumberYeah but was that a failure here or in the video? Because the video seems to be saying that kinetic energy and temperature are the same thing, while these guys are making fun of that idea for being a bit silly. If not specifically because of the science of the thing.
@@disappointedcucumber but if you would be able to keep the temperature of the portal the same (1-2 kelvin) at any time, you should be able to move the portal in theory. Because temperature being the only condition is far too simple
The thing is, this stuff is weird when you get into it. Light for example should be faster in one direction and slower in another if the earth was moving. But it wasn't. Because earth is moving, yes, but if something is in constant motion, what way is there to tell if its moving or not? There is no position in the universe where something is definitely truly static. Absolutely no way to tell. The universe just doesn't have a constant location. To sum: "meh the universe doesnt care"
They just wanted to show off there programming skills. My head canon fix for this is the portal would appear for a split second and use the laser to cut one of the things and then disappear, rinse and repeat.
@@redactedoktor or maybe they just couldn't in portal 1 and figured out how in portal 2 And used it. But it is only like, up/down/side-to-side movement, in respect to the opening of the portal. In a different part of the game, the introduction to the aerial faith plates i think, glados lowers the ceiling, and when the portal goes forward in respect to it's opening it does close. So portals either can only move along surfaces in respect to the way they're opened...or it's another limit they hit and didn't have the time to figure out and portals are intended to move in all directions. Either way, they do move, but under certain rules, and that isn't somethin to be ignored or handwaved away
@@againstfasces5222 I am finishing my Physics bachelors this year. I already took every Quantum Mechanics class necessary to graduate. This is absolutely not how Quantum Mechanics works. It is worse than negative mass, because it makes even less sense.
One problem. That was the bright side of the moon. That means the blazing sun was shooting light at it, essentially broiling the moon dust to a whopping 250 degrees fahrenheit. Because the moon doesn't have an atmosphere, the bright side of the moon has WAY more light reaching its surface than earth does. While being on there wouldn't be that bad, the moon dust is still super hot even with all the light it's reflecting.
Few games are timeless, given how well they were made. And the Portal games definitely are one of the best examples. Whenever I hear someone saying "I've never played Portal", I literally can't stop myself from telling them that for everything holy, they really should play the first *first*, no matter how old it is. Just because it's that good (aside the dated graphics) and because Portal 2 would make at best half as much sense without it.
Now im not science expert (still in highschool) but pretty sure Quantum Tunneling takes some time, where as in the game you teleport thru instantly (spoiler: like in Portal 2 boss fight scene, you shoot a portal to the moon which would be around 1 second to teleport through but that does not happen) and another thing, quantum tunneling is for a particle moving through a barrier... like a portal in front of wall, and portal behind the wall. But in the game You can shoot it anywhere and itll work
Funny thing about the moon rocks being portal-worthy, that was actually added on at the very end of development.. all the moon dialogue and references were added after designing the end scene of Portal 2, where they thought shooting a portal to the moon would be cool (which it was), but they then realized the ending had no correlation with the rest of the game. idk if it was a coincidence or not, but yeah, worked out pretty well with the science part too. Also, about non-moving portals, the physics engine was fully capable of doing that, since there actually are moving portals, but in only 1 level, the one where you cut off the deadly neurotoxin, and it sends only a laser beam through. I've seen a few speedrunners take advantage of this though, they found a way to let the portals in other rooms move; portals not being able to move was definitely a design choice I'm glad they implemented, had no idea it also correlated with the science behind it. Cool stuff. Anyways, rant's over, definitely subscribed, can't wait to see what else you can teach us!
@13:00 Another thing about moon dust is it's actually EXTREMELY sharp. On earth, sand is constantly being ground down and rounded off from friction, due to wind or water, what have you. The moon doesn't have that, so the sharp edges of the individual grains never got ground down. That basically makes lunar dust have similar physical effects as fiberglass or asbestos when inhaled, including potentially leading to cancer.
@@nobody.of.importance This might explain what led to Cave Johnson’s death. Since we hear him coughing in the last couple of his tapes, it’s likely that Cave’s illnesses damaged his respiratory system, and if grains of moon sediment are that sharp, it stands to reason that breathing in the stuff would cause severe lung damage. Plus, if so, it could also be considered a callback to the “all these spheres are made of asbestos” line.
@@jacksongibbs8998 Indeed, that's my hypothesis as well. On top of being wicked sharp, it also acts essentially as a free radical, ripping hydrogen atoms off of molecules in your body to stabilize themselves. It's all kinds of bad news to breathe in.
Every portal theory collapses because of the funny neurotoxin sabotage before the last Glados encounter in the first half of portal 2. God damn it valve
They just wanted to show off there programming skills. My head canon fix for this is the portal would appear for a split second and use the laser to cut one of the things and then disappear, rinse and repeat.
@@timgal5868 They even could have had the redirection cubes move on conveyors or elevators or something, and have you shine the laser at them in the direction they're moving. You can have moving lasers without having moving portals or even needing the player to stay involved after placing a portal.
While it's true that the portals close as soon as they're on a moving surface, there's actually a scripted event where you can put portals on a moving surface and the portals will stay there, still transferring the lasers going through which are used to cut the tubes transferring the neurotoxin. This isn't a critique on the video though, I just wanted to mention this. This is such a great video and you really inspire and I hope to one day be able to do a career in science.
I've always wondered about this. Because in theory, the Moon and the Earth are also both in constant motion, and so is everything else. Notably, the moving portals we shoot in the neurotoxin generator scene are shot onto panels which *already move*, i.e. they're also at a constant velocity - whereas any situation where a moving portal fizzles is caused by the surface coming into motion from a stop, i.e. adding velocity. So it might not be the movement closing the portal, but rather the acceleration. I think it's more than likely that the portals are self-stabilizing, i.e. they hold eachother open, and when one portal suddenly has to compensate for added kinetic energy (via acceleration), it overtaxes the link and the portal fizzles.
@@JRexRegis I think canonically they can always move and accelerate however much they want. It's just that programming that to work in a stable fashion is really difficult, so Valve just made moving portals usually impossible. You can use Hammer to make a map with a moving portal, and you'll see that it's very buggy when physics objects go through it. So Valve only reserved the moving functionality for that one level, where it doesn't have to deal with physics objects.
There’s only one thing about this theory I disagree with: I refuse to believe portals can’t move. Not only because of P2’s neurotoxin puzzle, but also because the Earth is moving. The Moon is moving. Everything is moving. Completely stopping motion is as impossible as absolute zero temperature.
How can do you know all this but not get the basic principles behind the portal paradox? Answer B in the portal paradox does not suggest that the box gains any momentum. The box is moving upwards along the normal of the orange portal the whole time, from the perspective of the space outside the orange portal. If you were to look into the orange portal before the box has gone through, you would see the box moving towards you at the same speed as it will be at when it exits the portal. There are two ways for answer A to be correct. If momentum is not conserved when objects pass a portal as you kind of imply, answer A would be correct but then no momentum would be conserved ever and in the game, momentum is definitely conserved so that can't be it. The other way that answer A could be correct is if the box never leaves the reference frame around the blue portal. That reference frame would have to stretch through the portal opening out of the orange portal. It does however seem much more natural for the portal crossing itself to delineate the barrier between the two reference frames.
Congrats on entering your last semester of your masters. You’ve come a long way. Also, glad you’re putting your knowledge to good use so we can finally, *TRULY* understand Portal
@@Eldrich09 portals can't move because of technical limitations. unless you wanna somehow argue that literally the entire neurotoxin chamber was diegetically moving, portals canonically can move. i'm also pretty sure the moon moves relative to the earth, please let me know if i'm wrong
@@nddragoon It’s not because of technical limitations and the neurotoxin chamber proves it, if you want to, you can mod the game to make portals move. Most likely, the only reason they have the portals move in that specific chamber, was because they thought it looked cool.
@@Eldrich09 whatever the reason for portals not moving elsewhere, portals still move in the neurotoxin chamber and on the moon. there's literally no argument you could make for portals not moving when portals move in canon not once but twice in scripted sequences. it also would make no sense for portals to be immovable because literally everything is in motion all of the time.
@@nddragoon Like I said, there’s no technical limitations, they chose to not have the portals move anywhere else, besides one small chamber that did so just because it was cool. As for the moon, you’re wrong, after a few seconds of the portal being open, where Wheatley got sucked out into space and GLaDOS saves you, the portal closes off. While the portal gun did get sucked out into space too, it didn’t seem to be destroyed or anything. It closed on its own.
I come from a family of lawyers and scientists (specifically chemists), so naturally I have to give a sub to you. After rewinding segments several times it all started to make sense. Great video
Currently working on my bachelor's in astrophysics and am just learning about superconductivity and love to see the applications of the science from someone who actually uses correct terminology and provides backings for their work. Definitely earned a sub
I really don't think that tunneling could do anything close to what portals do: 1. Tunneling involves an object overcoming a potential barrier -- in this case, a wall -- and crossing it. In the game, you can throw a portal on a wall and another portal in a completely different wall. An object that crosses the portal wouldn't be overcoming a barrier, it would be appearing somewhere else. The issue here isn't the issue of going through stuff, it's the issue of going through *space*. 2. Tunneling can't be used to make an object travel faster than the speed in which it was going. In the game, it's clear that if you have a portal by your side and another one very far away, you can go through the first one at any speed and arrive on the other one instantaneously. [SPOILERS FOR PORTAL 2] For example, the Moon is 1.3 light-seconds away. We don't see that delay when we travel there. [END OF SPOILERS] 3. I don't think tunneling could change the angle the object was moving in. Portals do. This wouldn't have bothered me this much if you hadn't sounded so confident about you said. The rest of the video was good.
Yes! Even though I don't have nearly the credentials of the video author, a lot of what was said was definitely just confidently incorrect. So frustrating to see all the other comments jumping on this video's self-congratulatory know-it-better notion
I think it's just a sum of quantum teleportation and quantum tunneling is that makes any sense. But again I don't get it isn't the probability wave of large objects almost like lambda
@tiagomacedo7068 Thank you. This is correct. Quantum tunneling is a local phenomenon. The probability of tunneling decays exponentially with distance. Ain't no way anything is tunneling from one wall to another completely different wall.
@@kangalio I dunno why the guy is flashing his credentials but it's dumb. TBH I have to imagine the guy isn't getting grilled hard on the physics theory because the theory presented here is very incoherent. His experimental knowledge could be fantastic, but the theoretical grounding is just wrong. Tunneling cannot create portals by itself, and even if you add some other kind of physics in, is the portal really based on the physics of tunneling, or that other kind of physics that actually, ya know, connects the two points?
Im SUCH a sucker for quantum tunneling and superconductivity. absolutely banger job with this video shuck! Got a feeling this video will blow up, so here's my algorithm comment. 👍
@@TheShuckmeister “if a portal were to move it would cease to exist” how did we get rid of neurotoxin exactly? We sliced tubes with lasers using *moving* portals. Can you please explain this?
@@speeder.x9983 yeah , that's the only time where this rule is broken. I think it's more of a plothole than anything , the dev had no real idea of how to do that otherwise
The portal wouldn't cease to exist. You would have to extrapolate based on the movements as it's traveling through that of s which equals that of space in that of the value through that of v, which equals that of the velocity when traveling through you would just have to know where all the particles lie in between that of its. Scripted space and time based on the experiment parameters. Once you know that the actual AI within your tool will be able to recompense that of the velocity and triangulate through that of the. S of space to understand exactly how fast and where exactly you will be on that of the other end. @speeder.x9983
this video just got recommended to me and i've never been happier from a youtube video. i absolutely LOVE portal and ALL kinds of science, especially physics, and i'm really overjoyed to see my two most top interests in one video. thank you :)
1:10 I'm not actually here from the algorithm. I was searching for a portal theory video that would take a different perspective and happened to come across this one. It's really interesting and let me say, actually showing a real experiment related to the topic at hand is very cool. However there are a few things I feel should be noted. First, I would like to defend Henry from MinutePhysics as he mentioned the word "wormhole" just once and only as a possibility, never stating it's necessary the case. Second, while you do make a compelling argument, it's not a definite proof, as they are 2 in-game occurrences that are a direct contradiction to your hypothesis. In test chamber 19 from the first Portal game you can create a portal right next to a burning fire with absolutely no problem. In the second Portal game there's a section where you have to cut the neurotoxin generator pipes using a laser and a moving portal. So there's still thought to be had on the matter.
I watched your video a few days ago before doing a practice speedrun of the first Portal game, I gasped audibly at what I discovered. There are two occasions where you can find that projector screen in parts of the game. If you wait, it'll scroll to a slideshow that reads: "Defense Logistics Agency solicits bids for development of fuel system icing inhibitor (FSII)" "Black Mesa design inhibits ice, nothing more" "Aperture Proposal inhibits ice, and is also a fully functioning Disk Operating System" If this means what i think it means, then you're f***ing spot on. Aperture IS really cold, considerably absolute zero. Canonically, GLaDOS is the mainframe for the facility, also doubling as an anti-icing system. I'd love to hear what you think of this!
As a current physics student with a keen interest in quantum mechanics I am trying really hard to focus on the concept of tunneling (which ngl I have never heard of before, this sounds hellishly cool) but Your avatar is very, very prettyyy...
i'm gonna be honest, i still don't really understand, i thought previously quantum tunneling can only let you pass through some sort of barrier, not change your location entirely
@@lunarkometIf you consider every object between you and your objective as a potential barrier I understand how someone with a superficial understanding of theory, but who likes to use difficult words to imply he understands it, could thing that. But, quantum tunnelling doesn't happen between multiple distinct potentials because eventually the object is going to be collapsed. When you colide an electron with a photon its wavefunction collapses. We can't observe the tunnelling directly, we never did. Something is going to collapse the object's wavefunction. There is no tunnel to be expanded. That is not how any of this works.
@@vidal9747 Also, unless I'm mistaken, quantum tunneling as we've observed it has only happened in nature because of the way an electron orbital works. i.e. the orbital is a cloud of potential positions which, when collapsed, can cause the electron particle to be observed in a place it could not have physically reached. I.e. in order for any quantum tunneling to occur on an object larger than a single electron, the object would somehow have to behave like the waveform of a subatomic particle which is insane
I'm sorry you lost me half way through but I will definetely return until I somewhat understand it. Seriously underrated, the algorythm gave me this video and I am super happy.
I see a major flaw: the portals in the game Portal function like wormholes. As the video states, quantum tunneling and wormholes are two different concepts. Quantum tunneling, at least as far as i understand, is simply when particles pass through an object, the particles still travel through space like normal, they do not teleport across space. The portals in Portal allow teleportation via a doorway, like a wormhole. It is far more logical to assume the portals are wormholes, even if wormholes may not exist in real life.
Yeah by the end of the video I got a bit lost trying to make sense on how it was a "portal" The way he described that "metal oreo" with aluminum and lead seemed more like the electrons where just traveling through the layer of air in the middle, not connecting two different points in space. Maybe the two points get entangled or something? But I feel like the eliminates the whole point about disliking handwaving like with his point about negative mass. Edit: after doing a little tiny bit of research (a quick google lol) I think both of our interpretations of quantum tunneling is wrong because we're trying to fit it into classical mechanics. I'd still have to do a lot more digging but from what I've read so far there actually isn't any "tunneling". Meaning the electrons arent physically moving through the barrier, they're just appearing on the otherside. Tbh idk really. Rockets and engineering are my thing, not quantum physics... That stuff is confusing as hell.
@@kain4892 Correct that there is no "tunnel" involved in tunneling. Quantum tunneling is basically just a special case of *all* quantum particle motion. A quantum object has a wave function which describes its state. Say that state has a definite energy E. That state can move up to a so-called "potential barrier" of energy V > E, and classically it shouldn't be able to pass. This is like a ball being rolled up a hill but without enough momentum to get all the way up. However, quantum objects have a wave function which evolves via the Schrodinger equation. That equation causes states to smoothly diffuse out over space, and importantly it allows the wave function to penetrate the potential barrier, though it gets smaller exponentially through the barrier. This means there is a small but finite chance of finding the particle of energy E on the other wise of the barrier V>E. Importantly, there is nothing special going on here. If there was no barrier, the particle would still "tunnel" around space in this way; interacting with the local environment, seemingly "jumping" around. It's just that there wouldn't be a classically disallowed position being observed. But QM doesn't care what is classically disallowed (except insofar as it needs to reproduce it in the macroscopic limit). So "tunneling" is just business as usual for quantum objects. It only seems special because it violates our intuition. And it certainly doesn't connect two points in space.
@@kain4892 Also as he stated in the video, when particles quantum tunnel they lose momentum, but we know from the game that momentum is conserved between portals.
@@Roset595 furthermore, he says portals can't move, which is easily disproven by the neurotoxin generator puzzle, and regardless it fundamentally makes no sense because velocity is relative, so there can't be special rules for "moving" vs "non-moving" objects
Portal explicitly states that momentum does not change when passing through the portal. It's a key gameplay mechanic. Pretty sure you said there would be a loss of momentum. Also there are moving portals in Portal 2 during the destruction of the neurotoxin generator. Quantum tunneling to a surface other than the opposite side of the barrier.... How does that work?
Portals are changing your momentum all the time, because it can change the DIRECTION of your momentum. Momentum is a vector quantity and not only the absolute value/magnitude must be conserved, but also the direction. And if you jump to another height, your break conservation of energy as well 🙈
@@schetefan24 Portals break Euclidean geometry. On curved spacetime you can't just compare a vector at one point in space with a vector at another, you have to use something called the connection coefficients, also called Christoffel Symbols, for the manifold, in order to move a vector from one place to another to compare. I won't pretend the Portals in the video game are valid solutions to GR but what you're saying just isn't true. It is perfectly possible for vectors to seemingly change direction in non-flat spacetime, due to nonzero connection coefficients.
An easy example is a 2-dimensional sphere (the surface of a sphere/ball). Imagine a vector tangent to the surface. This vector could indicate the direction of momentum of some object constrained to be on the sphere. Let’s say we have two vectors at opposite sides of the sphere at the equator, one pointing towards the North Pole, the other to the South Pole. From the perspective of looking at these vectors when we “embed” the sphere in 3 dimensions, the vectors appear to point in opposite directions. But, if we slide the one pointing towards the North Pole along the direction it is pointing (but constrained to the surface still), that vector will slowly rotate. When it gets to the North Pole, it will be pointing at 90 degrees to its previous direction, and when it arrives at the opposing side of the equator it will in fact be pointing the same direction as the other vector that was seemingly its opposite. From the pov of the embedding space, those two vectors weren’t equal and had to change direction as they moved around the sphere. But if we didn’t embed the sphere in 3D, and just looked at it like a 2D space, those vectors are equal and never changed as they moved around the sphere.
@@againstfasces5222 And if you move along the equator instead, your vector is aligned in the opposite direction... (Also see the hairy ball theorem) I don't think that your argument applies to the momentum. You can treat the portals and the player as a single system and if viewed from the outside, momentum must be conserved. Since you can shift both together to an arbitrary place and nothing changes, momentum must be conserved (Noether's theorem). And even if it would be a curved space, we should also see optical effects, but the lasers go straight through in all directions. The game also seems outside of the portals like a pretty normal euclidean space to me ;)
An amazing video but I have few notions: 1. "Portals can't move" - but isn't everything constantly moving? That's the point of The Relativity Theory - everything is moving, everything is changing and the only thing that maters is a point of view/reference. 2. An output portal shooting out the cube doesn't mean random speed out of nothing or any increase of sum energy of volume it's in. One way to determine speed is a rate in which (elements of) object travel through space (a rate in which they switch their positions in a direction): 2a) If you just throw a cube for it to reach speed N, then any part/molecule/atom/electon/... (like one on side of cube which faces direction of movement) will give up its position to a next one (like one, that a bitty bit closer to cube's center) in M time (whatever micro-/mini-/nanosecond that would be). 2b) Same thing if you throw a portal with N speed at the stationary cube, then any part of it that just past portal's plane will be pushed away (so next one could take it's position) in M time. Video by developmer of Portal 64 would demonstrate it more clearly. I think people who are yell about the answer to "the paradox" being option A are tend to forget that in world of Portal you can just place one portal above other one, pour some water and get a perpetual motion machine. Which is kinda balanced by idea of putted portals constantly spending titanic amounts of energy sucked out of associated black holes. So there's no infinite energy - you're just wasting energy of (god knows how captured/generated) tiny black holes to do cool stuff. P.S. Isn't that funny how humans find things to argue about which can even may be impossible to do/check in a millenia?
Let's ignore the fact that there are moving portals in portal 2. However if a portal can't move, explain to me what you mean with movement, or what your point of reference is. Because the Earth moves around the sun. And our solar system moves in our galaxy. And if the earth moving isn't a problem then how would a moving platform (on which a portal would be placed) relative to the earth be a problem since there is no relative movement between the platform and the portal itself. In the grand scheme of things the portal isn't moving relatively to the platform any more whether you move the platform or not since the speed of the moving platform is negligible. Or are we talking about the portal moving relative to the earth? But then you can't place a portal on the moon since the moon moves relative to the earth. But why would the earth be the point of reference in the first place? It's just one of many floating pieces of mass in space. Movement is relative so it really isn't an argument. Acceleration yes, movement no. In essence portals technically can move (or rather the platform on which the portal is placed) since there is no movement between the portal and the platform English is not my first language so ignore any mistakes

"Wormholes have nothing to do with quantum tunneling" Relatively new work by people such as Susskind generally titled ER = EPR suggest that wormholes and entanglement are the same phenomenon. It's interesting stuff. Stanford has some lectures on it if you want to learn more.
I am a little late but when you talk about why portals can't move irl and how they don't move in game, there is an instance where they do in the second game. When destroying the neurotoxin generator you put a portal on a moving tile which destroys the tubes. It was ALMOST perfect.
"its not quantum tunnels" they say "its wormholes" they say meanwhile me(an intellectual): aperture science handheld QUANTUM TUNNELING device, which is the real name of the "portal gun" so it obviously makes wormholes and isnt quantum tunneling!(this is joke it is a quantum tunnel not wormhole)
A wormhole is still a better explanation for the portal gun than quantum tunneling. This whole video was kinda a pain to watch as a science enthusiast myself, much more so than Austin's video.
I am not nearly as big brained as this man, but I thank him for putting these super smart topics into digestible form for myself, I’m gonna be writing a series mainly focusing around individuals with psychic type abilities, but I want to make them crazy and bizarre and science focused, so these videos help me a lot! Thanks Shuckmeister!

You missed one part in the Portal 2 game where it breaks the rule of portals not being able to move. This part of the game is the worst part (imo) because it breaks a fundamental law in the game (according to the video), and also breaks a game mechanic at the same time, since this is the part where some people get stuck because they've been sloppily introduced to a game mechanic that doesn't even come back. The part I'm talking about is, of course, the part where you have to use lasers to cut GlaDOS' neurotoxin supply
That part is probably there to show that portals can canonically move, they just usually don't move because that would be really hard to program for physics objects going through them. Also, I've watched a lot of playthroughs, and pretty much everyone immediately sees the solution once they notice the moving surfaces. And they never even realize that it broke a "fundamental law in the game", because moving surfaces destroying portals has never been a real game mechanic (it doesn't affect the solution to any puzzle, other than making you have to wait a bit for surfaces to stop moving, and isn't used as part of the solution to any puzzle).
yeah, cranking up the power supply to an unspecified process would definitely cause quantum tunnels to form between spacially unconnected points and would definitely allow objects to pass through 100% of the time with negligible mass loss. definitely. definitely.
this guy literally doesnt even understand quantum tunneling. Electrons can tunnel through a barrier; not across the room from one wall to another. Or, they *can*, but it's literally googols of times more likely for them to tunnel somewhere else closer to the original wall. You can't just point a gun at two walls and "link" them thats not how tunneling works **at all**.
@@voyagerwitchFurthermore, how the wavefunction would not be collapsed? Like, wtf? Quatnum tunnelling happens in a lot of cases because the particle is observed in the other side (by a photon) and it's wavefunction collapses. While it has not been observed it is at the same time inside the container and outside the container. The process is not as simple as of walking trough a tunnel. Furthermore, there are higher and lower potential wells to tunnel trough. This is totally and utterly ridiculous. It is clear that an Physics Engineering grad student is not a Physicist. This amounts to pseudo-science.
@@vidal9747right, you can quantum tunnel through a potential well (like a wall), not... the fabric of spacetime. at that point you are in fact talking about wormholes
saw this pop up in my recommended, read the title and thought "finally somebody made a video about portals that doesn't explain it with wormholes" very cool video, totally deserves more views; i'm commenting (& liking and subscribing with notifications) so hopefully more people can find this and hear a much more plausible explanation that's rooted in real experiments (with cool graphs)! also i never would have realized the black hole is used as a power source, the revelation that the fan was there to cool it because it's generating energy is very big brain
portals vanished is actually proven, if indirectly. on the part where glados lowers the ceiling because you're too heavy for the faith place, any portal you had on their vanishes. that might just be a gameplay thing but its cool
@@lmahu6627 Yeah, and then there are moving portals in the neurotoxin production room lmao. I think Valve always wanted to have moving portals but couldn't code them properly, so they had to make the neurotoxin part scripted to make it work, but this means that moving portals are actually canon, and them closing during the movement of plates is either non-canon and just a gameplay dissonance thing - or GLaDOS closes moving portals in chambers deliberately.
@@Lernos1 yeah, the only reason why portals can't move outside the neurotoxin room is design and coding constraints. the neurotoxin room makes it perfectly explicitly clear that portals can move in canon and like logically it also would make no sense for portals to not be able to move, considering the earth is constantly orbiting and rotating, and at a smaller scale there are also vibrations and micro-earthquakes and whatnot.

The algorithm finally dropped this in my lap two years after it was published. Loved it.
E=MC²=V/s² Where V is equal to velocity divided by that of space of S², which equals that of the ultimate amount of energy to that of matter that is equal to be transferred to based on the distance that is allowed from the amount of energy that is first received. You would need at least 5 miniaturized fusion devices to be able to give enough energy for it to be possible. Which is equal to 500000 mega, jewels of energy and 500000 V of that energy to allow for the amount of time differential to allow that of a movement of the portal on the first start while the secondary portal is at the stationary Designation.

"A portal would cease to exist if it started moving"
Neurotoxin generator level:
This is a developer command in Portal 2 and afterwards exclusively. This is only to make a good puzzle element. I do not believe that it was fully meant to disprove someone who literally has a masters degree.
@@itstimeforMario64PLAYER it's only used in one puzzle because portals are technically complicated and moving portals cause issues that dont really pop up in a puzzle where you're not able to traverse or send objects through the portals. the fact that they can't move in most of the game doesn't mean you don't literally see first hand how the portals are moving. saying portals can't move is to completely ignore both the important neurotoxin sequence and the last portal you shoot in the game, at the moon, which is undeniably moving relative to the earth's surface. portals being unable to move makes zero sense if you wanna apply any kind of real world logic. this whole video makes very little sense when you look past the 10 dollar words and parading of credentials
i think it has something to do with the conditions in which the portals are created, for example if a portal is created in a moving surface and the movement of that surface keeps stable it would still link both portals if the conditions mantain the same, same aplies to the angle the portal is created in, we never saw a portal move in the same direction the the "opening" is, that would be an answer to the neurotoxin sequence
Let us assume that portals can be created on moving surfaces. That rule is never explicitly stated in game, at least not that I know of, and the neurotoxin puzzle proves it is possible. Whether it is only possible under certain conditions or not, like @foxhdn233 said, it is a fact. With that said, I see no reason that option A of the portal paradox would not be the correct answer. To quote GLaDOS "You appear to understand how a portal affects forward momentum, or to be more precise, how it does NOT."
This year I'll get my Master's Degree in Physics. I see a few problems with your logic:
1. Tunneling does not explain why teleportation in the game is instantaneous. In quantum tunneling, the wave fuction takes time to propagate through the barrier. Why am I so sure that in-game this phenomenon is instantaneous? Just watch the cutscene when you defeat GLaDOS, I don't want to make spoilers.
2. You correctly explained the lose of momentum (energy) when passing through the barrier. But that does not explain the change in direction of momentum of the outgoing particle. It could be possible if the potential barrier is not spacially homogeneous but that cannot be guaranteed for every wall you choose to place a portal on.
3. Not only the direction of momentum changes, but also the position of the outgoing particle does. The only explanation I could come up with is that none of the white surfaces in the game are actually superconductors. Instead, they become superconductors ONLY when a portal is placed on them (suppose that it is possible for the sake of our sanity). That way, the chances of tunnelling to the other superconductor far away (the other portal) are much greater than tunneling to a random wall in the room. This could be a flawed statement since in-game 100% of times the object passing through the portal appears in the other portal instead of a random wall (not to mention that also 100% of particles composing the object tunnel to the same wall)
I hope I made the statements clear and I'm open to discuss this with anyone, even without a Physics background.
I'm not sure if it is instantaneous. When you shoot the Moon with the portal gun in the finale of Portal 2, it takes a couple of seconds between when you fire and when the portal actually opens. That fits with the effect travelling at the speed of light.
@@Roxor128 That is not related to what I said. I didn't mean the time between shooting and portal appearing. I was talking about the time between entering a portal and appearing on the other side. When you shoot the moon and things start to go through the portal, they appear on the Moon instantaneously, including you.
To be fair, on the first point, Aperture has already done other stuff that should break laws of physics. We could just excuse it with "Aperture has godlike technology"
@@kiwenmanisuno I see. And that would be truly GODlike since it breaks General Relativity, making it possible for information to travel faster than the speed of light.

"Portals cannot move as they would cease to exist in doing so."

yeah it's kinda silly because portals are not frozen in space because they would be constantly moving, so trying to say they CAN'T move only works if the portal is in space with zero motion.
@@objectionablycurious This is kind of failing to understand what temperature is. Temperature is not the same as kinetic energy, temperature is a measure of the average kinetic energy of individual particles.
@@disappointedcucumberYeah but was that a failure here or in the video? Because the video seems to be saying that kinetic energy and temperature are the same thing, while these guys are making fun of that idea for being a bit silly. If not specifically because of the science of the thing.
@@disappointedcucumber but if you would be able to keep the temperature of the portal the same (1-2 kelvin) at any time, you should be able to move the portal in theory.
Because temperature being the only condition is far too simple
The thing is, this stuff is weird when you get into it. Light for example should be faster in one direction and slower in another if the earth was moving. But it wasn't. Because earth is moving, yes, but if something is in constant motion, what way is there to tell if its moving or not? There is no position in the universe where something is definitely truly static. Absolutely no way to tell. The universe just doesn't have a constant location.
To sum: "meh the universe doesnt care"

@@redactedoktor or maybe they just couldn't in portal 1 and figured out how in portal 2 And used it.
But it is only like, up/down/side-to-side movement, in respect to the opening of the portal. In a different part of the game, the introduction to the aerial faith plates i think, glados lowers the ceiling, and when the portal goes forward in respect to it's opening it does close.
So portals either can only move along surfaces in respect to the way they're opened...or it's another limit they hit and didn't have the time to figure out and portals are intended to move in all directions.
Either way, they do move, but under certain rules, and that isn't somethin to be ignored or handwaved away

One problem. That was the bright side of the moon. That means the blazing sun was shooting light at it, essentially broiling the moon dust to a whopping 250 degrees fahrenheit. Because the moon doesn't have an atmosphere, the bright side of the moon has WAY more light reaching its surface than earth does. While being on there wouldn't be that bad, the moon dust is still super hot even with all the light it's reflecting.
Also the earth is moving, so if you could really make a permanent portal it would have to be able to move.

Funny thing about the moon rocks being portal-worthy, that was actually added on at the very end of development.. all the moon dialogue and references were added after designing the end scene of Portal 2, where they thought shooting a portal to the moon would be cool (which it was), but they then realized the ending had no correlation with the rest of the game. idk if it was a coincidence or not, but yeah, worked out pretty well with the science part too.
Also, about non-moving portals, the physics engine was fully capable of doing that, since there actually are moving portals, but in only 1 level, the one where you cut off the deadly neurotoxin, and it sends only a laser beam through. I've seen a few speedrunners take advantage of this though, they found a way to let the portals in other rooms move; portals not being able to move was definitely a design choice I'm glad they implemented, had no idea it also correlated with the science behind it.

This might explain what led to Cave Johnson’s death.

Gordon doesn’t need to hear all of this, he’s a highly trained professional.
While it's true that the portals close as soon as they're on a moving surface, there's actually a scripted event where you can put portals on a moving surface and the portals will stay there, still transferring the lasers going through which are used to cut the tubes transferring the neurotoxin. This isn't a critique on the video though, I just wanted to mention this. This is such a great video and you really inspire and I hope to one day be able to do a career in science.
I've always wondered about this.
Because in theory, the Moon and the Earth are also both in constant motion, and so is everything else. Notably, the moving portals we shoot in the neurotoxin generator scene are shot onto panels which *already move*, i.e. they're also at a constant velocity - whereas any situation where a moving portal fizzles is caused by the surface coming into motion from a stop, i.e. adding velocity.
So it might not be the movement closing the portal, but rather the acceleration. I think it's more than likely that the portals are self-stabilizing, i.e. they hold eachother open, and when one portal suddenly has to compensate for added kinetic energy (via acceleration), it overtaxes the link and the portal fizzles.
@@JRexRegis I think canonically they can always move and accelerate however much they want. It's just that programming that to work in a stable fashion is really difficult, so Valve just made moving portals usually impossible. You can use Hammer to make a map with a moving portal, and you'll see that it's very buggy when physics objects go through it. So Valve only reserved the moving functionality for that one level, where it doesn't have to deal with physics objects.
There’s only one thing about this theory I disagree with: I refuse to believe portals can’t move. Not only because of P2’s neurotoxin puzzle, but also because the Earth is moving. The Moon is moving. Everything is moving. Completely stopping motion is as impossible as absolute zero temperature.
and movement is relative, so there's not really any such thing as "not moving"
Thats actually incredible. Didnt know shuck was that educated on the matter. Good luck with finishing your uni.
He is not.
@@vidal9747he is educated, and he is applying his education in a place that does not require his education
How can do you know all this but not get the basic principles behind the portal paradox?
Answer B in the portal paradox does not suggest that the box gains any momentum. The box is moving upwards along the normal of the orange portal the whole time, from the perspective of the space outside the orange portal. If you were to look into the orange portal before the box has gone through, you would see the box moving towards you at the same speed as it will be at when it exits the portal.
There are two ways for answer A to be correct. If momentum is not conserved when objects pass a portal as you kind of imply, answer A would be correct but then no momentum would be conserved ever and in the game, momentum is definitely conserved so that can't be it.
The other way that answer A could be correct is if the box never leaves the reference frame around the blue portal. That reference frame would have to stretch through the portal opening out of the orange portal. It does however seem much more natural for the portal crossing itself to delineate the barrier between the two reference frames.
Ok, like, i appreciate the authenticity of a legit scientist doing this, but it Definately opens with a lot of anger

@@Eldrich09 whatever the reason for portals not moving elsewhere, portals still move in the neurotoxin chamber and on the moon. there's literally no argument you could make for portals not moving when portals move in canon not once but twice in scripted sequences. it also would make no sense for portals to be immovable because literally everything is in motion all of the time.
@@nddragoon Like I said, there’s no technical limitations, they chose to not have the portals move anywhere else, besides one small chamber that did so just because it was cool.

I really don't think that tunneling could do anything close to what portals do:
1. Tunneling involves an object overcoming a potential barrier -- in this case, a wall -- and crossing it. In the game, you can throw a portal on a wall and another portal in a completely different wall. An object that crosses the portal wouldn't be overcoming a barrier, it would be appearing somewhere else. The issue here isn't the issue of going through stuff, it's the issue of going through *space*.
2. Tunneling can't be used to make an object travel faster than the speed in which it was going. In the game, it's clear that if you have a portal by your side and another one very far away, you can go through the first one at any speed and arrive on the other one instantaneously. [SPOILERS FOR PORTAL 2] For example, the Moon is 1.3 light-seconds away. We don't see that delay when we travel there. [END OF SPOILERS]
3. I don't think tunneling could change the angle the object was moving in. Portals do.
This wouldn't have bothered me this much if you hadn't sounded so confident about you said. The rest of the video was good.
Finally someone in this comment section not saying how this person is smarter than them
Yes! Even though I don't have nearly the credentials of the video author, a lot of what was said was definitely just confidently incorrect. So frustrating to see all the other comments jumping on this video's self-congratulatory know-it-better notion
I think it's just a sum of quantum teleportation and quantum tunneling is that makes any sense. But again I don't get it isn't the probability wave of large objects almost like lambda
@tiagomacedo7068
Thank you. This is correct. Quantum tunneling is a local phenomenon. The probability of tunneling decays exponentially with distance. Ain't no way anything is tunneling from one wall to another completely different wall.
@@kangalio I dunno why the guy is flashing his credentials but it's dumb. TBH I have to imagine the guy isn't getting grilled hard on the physics theory because the theory presented here is very incoherent. His experimental knowledge could be fantastic, but the theoretical grounding is just wrong. Tunneling cannot create portals by itself, and even if you add some other kind of physics in, is the portal really based on the physics of tunneling, or that other kind of physics that actually, ya know, connects the two points?

The portal wouldn't cease to exist.

Scripted space and time based on the experiment parameters. Once you know that the actual AI within your tool will be able to recompense that of the velocity and triangulate through that of the.

Cant wait for him to make an real life poptal gun
1:10 I'm not actually here from the algorithm. I was searching for a portal theory video that would take a different perspective and happened to come across this one. It's really interesting and let me say, actually showing a real experiment related to the topic at hand is very cool. However there are a few things I feel should be noted.
First, I would like to defend Henry from MinutePhysics as he mentioned the word "wormhole" just once and only as a possibility, never stating it's necessary the case.
Second, while you do make a compelling argument, it's not a definite proof, as they are 2 in-game occurrences that are a direct contradiction to your hypothesis. In test chamber 19 from the first Portal game you can create a portal right next to a burning fire with absolutely no problem. In the second Portal game there's a section where you have to cut the neurotoxin generator pipes using a laser and a moving portal. So there's still thought to be had on the matter.
Interesting observations
Aperture test subject Shuck has too much drip for physics
I watched your video a few days ago before doing a practice speedrun of the first Portal game, I gasped audibly at what I discovered.
There are two occasions where you can find that projector screen in parts of the game. If you wait, it'll scroll to a slideshow that reads:
"Defense Logistics Agency solicits bids for development of fuel system icing inhibitor (FSII)"
"Black Mesa design inhibits ice, nothing more"
"Aperture Proposal inhibits ice, and is also a fully functioning Disk Operating System"
If this means what i think it means, then you're f***ing spot on. Aperture IS really cold, considerably absolute zero. Canonically, GLaDOS is the mainframe for the facility, also doubling as an anti-icing system. I'd love to hear what you think of this!
The stuff I watch instead of going to bed is INSANE
As a current physics student with a keen interest in quantum mechanics I am trying really hard to focus on the concept of tunneling (which ngl I have never heard of before, this sounds hellishly cool) but
Your avatar is very, very prettyyy...
i'm gonna be honest, i still don't really understand, i thought previously quantum tunneling can only let you pass through some sort of barrier, not change your location entirely
He has no idea either, he is just biased torwards this idea because of his personal life
Yeah I'm gonna need an explanation for this too
My point exactly. This is nonsense.
@@lunarkometIf you consider every object between you and your objective as a potential barrier I understand how someone with a superficial understanding of theory, but who likes to use difficult words to imply he understands it, could thing that. But, quantum tunnelling doesn't happen between multiple distinct potentials because eventually the object is going to be collapsed. When you colide an electron with a photon its wavefunction collapses. We can't observe the tunnelling directly, we never did. Something is going to collapse the object's wavefunction. There is no tunnel to be expanded. That is not how any of this works.
@@vidal9747 Also, unless I'm mistaken, quantum tunneling as we've observed it has only happened in nature because of the way an electron orbital works. i.e. the orbital is a cloud of potential positions which, when collapsed, can cause the electron particle to be observed in a place it could not have physically reached.
I.e. in order for any quantum tunneling to occur on an object larger than a single electron, the object would somehow have to behave like the waveform of a subatomic particle which is insane

I see a major flaw: the portals in the game Portal function like wormholes. As the video states, quantum tunneling and wormholes are two different concepts. Quantum tunneling, at least as far as i understand, is simply when particles pass through an object, the particles still travel through space like normal, they do not teleport across space. The portals in Portal allow teleportation via a doorway, like a wormhole. It is far more logical to assume the portals are wormholes, even if wormholes may not exist in real life.
Yeah by the end of the video I got a bit lost trying to make sense on how it was a "portal"
The way he described that "metal oreo" with aluminum and lead seemed more like the electrons where just traveling through the layer of air in the middle, not connecting two different points in space.
Maybe the two points get entangled or something? But I feel like the eliminates the whole point about disliking handwaving like with his point about negative mass.
Edit: after doing a little tiny bit of research (a quick google lol) I think both of our interpretations of quantum tunneling is wrong because we're trying to fit it into classical mechanics. I'd still have to do a lot more digging but from what I've read so far there actually isn't any "tunneling". Meaning the electrons arent physically moving through the barrier, they're just appearing on the otherside.
Tbh idk really. Rockets and engineering are my thing, not quantum physics... That stuff is confusing as hell.
@@kain4892 Correct that there is no "tunnel" involved in tunneling. Quantum tunneling is basically just a special case of *all* quantum particle motion.
A quantum object has a wave function which describes its state. Say that state has a definite energy E. That state can move up to a so-called "potential barrier" of energy V > E, and classically it shouldn't be able to pass. This is like a ball being rolled up a hill but without enough momentum to get all the way up. However, quantum objects have a wave function which evolves via the Schrodinger equation. That equation causes states to smoothly diffuse out over space, and importantly it allows the wave function to penetrate the potential barrier, though it gets smaller exponentially through the barrier. This means there is a small but finite chance of finding the particle of energy E on the other wise of the barrier V>E.
Importantly, there is nothing special going on here. If there was no barrier, the particle would still "tunnel" around space in this way; interacting with the local environment, seemingly "jumping" around. It's just that there wouldn't be a classically disallowed position being observed. But QM doesn't care what is classically disallowed (except insofar as it needs to reproduce it in the macroscopic limit). So "tunneling" is just business as usual for quantum objects. It only seems special because it violates our intuition. And it certainly doesn't connect two points in space.
@@kain4892 Also as he stated in the video, when particles quantum tunnel they lose momentum, but we know from the game that momentum is conserved between portals.
@@Roset595 furthermore, he says portals can't move, which is easily disproven by the neurotoxin generator puzzle, and regardless it fundamentally makes no sense because velocity is relative, so there can't be special rules for "moving" vs "non-moving" objects
3 years late to this thing and I just.... Imma proceed to binge the rest of his videos.
*gathers trash, builds portal gun, expoldes, dies*
Portal explicitly states that momentum does not change when passing through the portal. It's a key gameplay mechanic. Pretty sure you said there would be a loss of momentum. Also there are moving portals in Portal 2 during the destruction of the neurotoxin generator. Quantum tunneling to a surface other than the opposite side of the barrier.... How does that work?
It doesn't. This dude is just making up random shit for algorithm clickbait, ironically enough.
Portals are changing your momentum all the time, because it can change the DIRECTION of your momentum.
Momentum is a vector quantity and not only the absolute value/magnitude must be conserved, but also the direction.
And if you jump to another height, your break conservation of energy as well 🙈
@@schetefan24 Portals break Euclidean geometry. On curved spacetime you can't just compare a vector at one point in space with a vector at another, you have to use something called the connection coefficients, also called Christoffel Symbols, for the manifold, in order to move a vector from one place to another to compare. I won't pretend the Portals in the video game are valid solutions to GR but what you're saying just isn't true. It is perfectly possible for vectors to seemingly change direction in non-flat spacetime, due to nonzero connection coefficients.
An easy example is a 2-dimensional sphere (the surface of a sphere/ball). Imagine a vector tangent to the surface. This vector could indicate the direction of momentum of some object constrained to be on the sphere.
Let’s say we have two vectors at opposite sides of the sphere at the equator, one pointing towards the North Pole, the other to the South Pole. From the perspective of looking at these vectors when we “embed” the sphere in 3 dimensions, the vectors appear to point in opposite directions. But, if we slide the one pointing towards the North Pole along the direction it is pointing (but constrained to the surface still), that vector will slowly rotate. When it gets to the North Pole, it will be pointing at 90 degrees to its previous direction, and when it arrives at the opposing side of the equator it will in fact be pointing the same direction as the other vector that was seemingly its opposite.
From the pov of the embedding space, those two vectors weren’t equal and had to change direction as they moved around the sphere. But if we didn’t embed the sphere in 3D, and just looked at it like a 2D space, those vectors are equal and never changed as they moved around the sphere.
@@againstfasces5222
And if you move along the equator instead, your vector is aligned in the opposite direction... (Also see the hairy ball theorem)
I don't think that your argument applies to the momentum.
You can treat the portals and the player as a single system and if viewed from the outside, momentum must be conserved.
Since you can shift both together to an arbitrary place and nothing changes, momentum must be conserved (Noether's theorem).
And even if it would be a curved space, we should also see optical effects, but the lasers go straight through in all directions.
The game also seems outside of the portals like a pretty normal euclidean space to me ;)
An amazing video but I have few notions:
1. "Portals can't move" - but isn't everything constantly moving? That's the point of The Relativity Theory - everything is moving, everything is changing and the only thing that maters is a point of view/reference.
2. An output portal shooting out the cube doesn't mean random speed out of nothing or any increase of sum energy of volume it's in. One way to determine speed is a rate in which (elements of) object travel through space (a rate in which they switch their positions in a direction):
2a) If you just throw a cube for it to reach speed N, then any part/molecule/atom/electon/... (like one on side of cube which faces direction of movement) will give up its position to a next one (like one, that a bitty bit closer to cube's center) in M time (whatever micro-/mini-/nanosecond that would be).
2b) Same thing if you throw a portal with N speed at the stationary cube, then any part of it that just past portal's plane will be pushed away (so next one could take it's position) in M time.
Video by developmer of Portal 64 would demonstrate it more clearly.
I think people who are yell about the answer to "the paradox" being option A are tend to forget that in world of Portal you can just place one portal above other one, pour some water and get a perpetual motion machine. Which is kinda balanced by idea of putted portals constantly spending titanic amounts of energy sucked out of associated black holes.
So there's no infinite energy - you're just wasting energy of (god knows how captured/generated) tiny black holes to do cool stuff.
P.S. Isn't that funny how humans find things to argue about which can even may be impossible to do/check in a millenia?
Yeah this video doesn't make sense 😭

Let's ignore the fact that there are moving portals in portal 2. However if a portal can't move, explain to me what you mean with movement, or what your point of reference is. Because the Earth moves around the sun. And our solar system moves in our galaxy. And if the earth moving isn't a problem then how would a moving platform (on which a portal would be placed) relative to the earth be a problem since there is no relative movement between the platform and the portal itself. In the grand scheme of things the portal isn't moving relatively to the platform any more whether you move the platform or not since the speed of the moving platform is negligible. Or are we talking about the portal moving relative to the earth? But then you can't place a portal on the moon since the moon moves relative to the earth. But why would the earth be the point of reference in the first place? It's just one of many floating pieces of mass in space.
Movement is relative so it really isn't an argument. Acceleration yes, movement no.
In essence portals technically can move (or rather the platform on which the portal is placed) since there is no movement between the portal and the platform
English is not my first language so ignore any mistakes

"Wormholes have nothing to do with quantum tunneling"
Relatively new work by people such as Susskind generally titled ER = EPR suggest that wormholes and entanglement are the same phenomenon. It's interesting stuff. Stanford has some lectures on it if you want to learn more.

Austin: Bring the special lemons, we have a house to visit.
... I may or may not have given him this idea when he made a mini-rant about this series on Twitter.
I am a little late but when you talk about why portals can't move irl and how they don't move in game, there is an instance where they do in the second game. When destroying the neurotoxin generator you put a portal on a moving tile which destroys the tubes. It was ALMOST perfect.
"its not quantum tunnels" they say
"its wormholes" they say
meanwhile me(an intellectual): aperture science handheld QUANTUM TUNNELING device, which is the real name of the "portal gun" so it obviously makes wormholes and isnt quantum tunneling!(this is joke it is a quantum tunnel not wormhole)
I love how Matpat correctly identified that the TARDIS's time vortex wasn't a wormhole but Austin still fell into that trap in his Portal video.
A wormhole is still a better explanation for the portal gun than quantum tunneling. This whole video was kinda a pain to watch as a science enthusiast myself, much more so than Austin's video.

You missed one part in the Portal 2 game where it breaks the rule of portals not being able to move. This part of the game is the worst part (imo) because it breaks a fundamental law in the game (according to the video), and also breaks a game mechanic at the same time, since this is the part where some people get stuck because they've been sloppily introduced to a game mechanic that doesn't even come back.
The part I'm talking about is, of course, the part where you have to use lasers to cut GlaDOS' neurotoxin supply
They can canonically move. It's simply that valve had limitations with the engine as going through moving portals is very buggy
That part is probably there to show that portals can canonically move, they just usually don't move because that would be really hard to program for physics objects going through them. Also, I've watched a lot of playthroughs, and pretty much everyone immediately sees the solution once they notice the moving surfaces. And they never even realize that it broke a "fundamental law in the game", because moving surfaces destroying portals has never been a real game mechanic (it doesn't affect the solution to any puzzle, other than making you have to wait a bit for surfaces to stop moving, and isn't used as part of the solution to any puzzle).

yeah, cranking up the power supply to an unspecified process would definitely cause quantum tunnels to form between spacially unconnected points and would definitely allow objects to pass through 100% of the time with negligible mass loss. definitely. definitely.
this guy literally doesnt even understand quantum tunneling. Electrons can tunnel through a barrier; not across the room from one wall to another. Or, they *can*, but it's literally googols of times more likely for them to tunnel somewhere else closer to the original wall. You can't just point a gun at two walls and "link" them thats not how tunneling works **at all**.
@@voyagerwitchFurthermore, how the wavefunction would not be collapsed? Like, wtf? Quatnum tunnelling happens in a lot of cases because the particle is observed in the other side (by a photon) and it's wavefunction collapses. While it has not been observed it is at the same time inside the container and outside the container. The process is not as simple as of walking trough a tunnel. Furthermore, there are higher and lower potential wells to tunnel trough. This is totally and utterly ridiculous. It is clear that an Physics Engineering grad student is not a Physicist.

@@Lernos1 yeah, the only reason why portals can't move outside the neurotoxin room is design and coding constraints. the neurotoxin room makes it perfectly explicitly clear that portals can move in canon and like logically it also would make no sense for portals to not be able to move, considering the earth is constantly orbiting and rotating, and at a smaller scale there are also vibrations and micro-earthquakes and whatnot.
