What Does a 4D Klein Bottle Look Like? 

hey action lab someone called "vlad slickbartender" asked for your help in a vid, i think just keep scrolling on his shorts page and you would see a video

Isn't 2:07 a misstatement? A 2D person would live in a 1D space. A 3D person lives in a 2D space and only sees in 2 dimensions. A 4D person, such as us, exists in the 4th dimension and sees everything in 3D.

No a 3D person lives in 3D space. Why would you think we are 4D

@@jeaniebird999 No. A 2D person would live in a 2D space but "see" 1 dimension. We live in 3D space but we only "see" 2 dimensions but we can perceive 3D.

@@rockik7844 You know, interestingly this universe looks like R^3 but the reality is it probably is not. Maybe we can say it's R^3 x T where T is the temporal dimension that is only perceived in one direction.

Well, that makes sense considering our brains are only 3D

It's because our 3D monkey brains are incapable of doing so. It's similar to how a chicken is incapable of recognizing itself in a mirror. It would know that a bird in front of it behaving very bizarrely, but it will never understand that its reflection is a live image of itself. Similarly, concepts like the fourth dimension and infinity are things that our primitive brains are just incapable of fully grasping.

Well, that makes sense considering it doesn't exist

Nobody can. Lol

well good news 3d objects, like your mind, in 4d would be flat so you could indeed wrap it around something but it'd have to be kinda small

Agreed. He explained that very simply. And I still don’t understand it.

@@nooey1487 ngl, they got us in the first half

@@nooey1487 Me too, some how I'm more confused now...😅

Yeah. I did not touch on this specific topic in my geometry classes in college. We covered handlebodies but not the fact that this is only a manifestation of the Klein bottle.

@@godisfraud you're not very bright are you

You've read flatland I'm sure right?

My thoughts exactly. You wouldn't be able to comprehend much shape at all in the 2nd dimension

And that's how you complicate this idea. Haha so essentially his realm contains the full circle but because he can only travel 4 directions. Up down left and right, he can see all sides of it but can only understand that it's a line, if he could travel in and out making it 6 directions he could see the full circle. This applies to us and light and dark.

He can. When he looks at it from different perspectives. Like we see the world in 2d objects, but our brain can create 3d objekts out of them, if we change perspective, or summon the 2d pictures from both of our eyes.

That's like saying we cannot see spheres and can only see circles

Actually i've thinking about this... the logic doesnt actually work out that way. A 2d object can not exist in a 3d space, so how would any part of a 4d creature be able to exist in 3d space. I was doing about a thought experiment about compressing fruit flies generation after generation, but ultimately you wouldn't be able to create a 2d creature ever, because you would never be able to get one of the dimensions to 0, the building blocks of our perceptible universe are made out of 3d objects, and can only create 3d objects, i would assume the same would apply to any other dimensions.

@@Omegka It's true that an entire (living) fruit fly could never exist in 2 dimensions at the same time. But, you could project a fruit fly into 2 dimensions. It actually happens all the time, it's called a shadow. If there were a 2d universe, the fly could also intersect it, and the 2d beings would see something very strange indeed. In fact, there could be physical objects in our world that are 3d projections of 4d objects. Either intersections, or (more likely) projections. Actually, every single moment is a 3d cross section of the 4d space that is time. There is another, more horrifying option, as well. You could UNFOLD a fly into 2 dimensions... I don't think the fly would survive, though.

Ok 4d is werid let forget about it

@@Omegka I believe you are correct that true 2d objects cannot exist in 3d space, from which it follows that 3d objects cannot exist in a 4d space. But then, further, you're suggesting that because we are 3d objects, we cannot coexist with 4d objects, so there's no big spy. This suggestion though relies on a possibly false assumption, which is that we are 3d objects living in a 3d space. What we know is that we can observe 3 dimensions (apart time), which does not exclude the possibility of other dimensions that we have not observed yet. This is the foundation of string theory. Perhaps we are 10 dimensional beings living in 10 dimensions, but we can reasonably perceive only 3 dimensions (and time, but that definitely feels different than the other 3). One possible explanation for our focus on these 3 dimensions could be that the other dimensions are relatively incredibly small. Imagine if everything in our 3d space would strictly have the width of an almost 2d fruit fly, that is still 3d. Similarly, the 4th dimension can be so small that we don't realize it's there.

@@Omegka Basically, you can manipulate lower dimensions from the higher ones, but not the other way around.

For real

She's lying probably 🤫

@@Insanearc Righty O!

Yeah, sadly this video isn't really making good advertising for 4D Toys or Miegakure.

Now we only have to find a manufacturer for such toys. ^^

a portal helps explain, thank's

Yes, and this portal is the next/4th dimension

Yes helpful.

I'm gonna go through it

I think portal isnt the 4th dimension, but the tunnel/space/something that connect the portal/object Like 2d explanation from the video it will look like stopped but actually still connected Sorry my english is bad

no one in 3d can get it

@@ruhto828 if that's true, then no one could ever even explain 4D, and everything we know about 4D has to be wrong, and 4D is inherently unfalsifiable. I'm personally very sceptical about the 4th spacial dimension, but I don't think your line of reasoning makes sense either.

I like 'Klein Strips' more than 'Klein Bottles' after all what use is a 'Klein Bottle' to a 4D being. Would be like us making a 'Möbius Strip' out of a piece of string! I imagine 2D beings calling the later a 'Möbius Bottle' and making videos about it!!!

@@gonegahgah They use it to water their plants 😂

What colour is the intersection plane?

@@gonegahgah it was a smooth transition in my mind. Very nice visual representation thanks

field's representation. very clever) so can we declare that 3d space it self is a field of energy?

this made so much sense and actually helped me visualize it, thank you!!

Glad somebody said it. This to me has always been the easiest way to visualize 4D. It's hardly that far-fetched considering how many 2D maps use a color spectrum to portray 3D height.

its

@@Noah_Zion I like how you corrected the punctuation rather than "like" where they meant "life"

@@newjerseyhater9237 they said life tho? XD (not trying to be rude :)

@@newjerseyhater9237 I don't think an apostrophe is punctuation though.

@@spacexplorer_ well it is a punctuation mark and related to commas so

Okay but share the video please!

Hello! What was the video? Can you please share with us?

@@BrendaMartinez-yg6qj It was probably something like this, using the points of shapes 2d to 3d: A square has 4 points, them and place it on the axis of the 3rd dimension, connect the lines and you get a cube

A tree is pretty similar in any dimension. It’s when you get to things like us and functional objects that there are a few tricks to make it easier. We bipeds have inside big toes, left toe on right foot, right toe on left foot. 4D beings would have the same thing with big toes either facing the centre of all the n-ped legs, or more likely having two big toes per foot each towards one of the adjacent legs, with many more other toes than we would have. I would hazard that the little toe would still hang on the outside away from the centre of the circle of legs.

@@gonegahgah what.

@@gonegahgah do you need grammarly

God I hate this new... commenting... format thing

@@sansdw7723 Our big toes serve a function by being between inside. This would be the natural evolution too if 4D were liveable but unlike our two legs they have a circle (or minimum triangle) of legs. I'm thinking, further possibly to what I said above, that maybe they need the major toe inside towards the centre of the circle of legs, and then secondary important toes between adjacent legs. So one major toe (per foot) plus two lesser major toes (per foot) plus a whole lot of increasingly minor toes?

oh nice

Thanks for this nice information!

Incorrect... If you only had one eye... Then you are correct... But 2 eyes allows us to see or perceice it has a depth.... 3rd dimension. And if you look at it for 5 seconds... Time, 4th dimension, especially if you drop the cube, then you can know exactly WHERE is was in that 4th dimension of WHEN. Not this quackery of "no volume". The thickness of glass is a volume. BUNK I SAY... BUNK...

@@ericcloudbolduc8840 i think depth perception is far different from what he was talking about because that just takes 2 2D images and merge them into something where you can focus on something with different depths. this isn't really 3D visual input. 2 dimensional people would see in one dimension because thats 1 lower that 2. they cant imagine what 3D looks like because they don't have a 2 dimensional vision input. even if they has 2 eyes, they would just be able to tell which object is far or close because of how their focus works which isnt actually 2 dimensional vision. similarly, we have 2D vision and the 2 different positions help us understand depth the same way that moving helps us understand depth. if we could really see 3D then we could see behind walls without walking around. we could see anything inside things too. this is why we cant imagine what 4D objects look like

@@ericcloudbolduc8840 I did not include a discussion about in depth. Every image you “see” is 2 dimensional. But you perceive 3 Dimensions.

@@Qaptyl stop imagining things that are fiction to justify other fiction... 2 dimensional people don't exist neither does 2d space... That's a plain not "space", space always has volume, and if they did they would see only line segments as in flatland or futurama... 4 dimensional beings... Would time travel... That's it... Dr. Who is a 4 dimensional being that moves through time and space. Enough with this nonesense. Your eyes see 2 2d images with your 2 eyes, and the brain converts the info into 3d... We are 3d and see in 3d, and we also perceive the passage of time, so are we 4d beings? People keep passing on this "if a being was 2d" nonesense to justify 4d. And when he says it has no volume... Wtf is he talking about... If you submerge them in water, the water line would be displaced in both cases... Unless you submerge it in an Olympic sized swimming pool to justify the water line didn't move to justify "it has no volume". There are plenty of ways to bullshit science to make it fit the bullshit narratives... Humans are going backwards in their understanding of physics and are becoming inferior specimens of inferior intellect.

This is actually a really good point and it gives me a new perspective on this whole idea of a 4th spatial dimension. This means that (hypothetically) a 4th dimensional being sees everything in 3 dimensions at one time. Really trippy to think about.

Light up a blunt and inhale the smoke. When you exhale, before you know you are floating in the fourth dimension amongst the smoke clouds. 🌬️💨☁️

I like the idea and would appreciate if I could find a demonstrated of this technique

I use another technique to visualise 4D, which is the gradient map (a.k.a heat map). We can use colors to visualise the height of each point on a 2D map of a mountain range. Let's say we use red for "high", green for "neutral", and blue for "low". Now imagine that the glass bottle in this video has colors that gradually change between red, green, and blue, so that the part where it "intersects itself" has the "tube" as red and the "surface" as blue. The red and blue would overlap (and create purple). Fortunately we are familiar with understanding "red+blue=purple", and we are using green as "neutral". Therefore, as we see purple, we can understand that there are 2 separate parts, red and blue, meaning "high" and "low", that do not intersect. Using the same technique, we can draw an illustration of the Mobius strip on a flat plane.

@@amaneyuuki6569 We have seen this technique in old school printed maps. But you cannot see through the mountains with this technique. You can just justify the elevation with this. Btw good suggestion. 4D is not practical out of the computer simulation. You have to accept this fact. Unless you are high af.

@@sagnikmaity1444 You can "see" through a mountain, if you use a similar technique to visualise a tunnel (with varying elevation) through the mountain. We would have to use colors differently. We use green for the mountain, ranging from dark green (low) to bright green (high). We use red for the tunnel, ranging from dark red (low) to bright red (high). Basically we are using the "alpha channel" as the "elevation". As we are familiar with 3 base colors, we can visualize 3 things (for example: surface and 2 tunnels) at the same point of the 2D map.

I click this video the second I saw the title, thought this is a new Cliff Stoll video!

Same here

I prefer Klein Strips to Klein Bottles. A Klein Bottle serves no purpose to a 4D being. It would be like us forming a Möbius Strip from a piece of string…

So Hypothetically, if I make a physical 5D Klein Bottle, that's time travel.

That’s right!

when DID he ever disappoint us?

Yep!

@@Infinixel never

@@Maliktevin1643 sup

i agree

Yea becuz this contents is prtty much stolen like the examples used here are exaclty the same as an other youtuber he used an app here which ws tht same exact youtubers shame he didnt credut them

Its the loop of all time 🔥🔥🔥🤨👾🇸🇪🤐

How could time possibly be the 4th dimension when it exists in the 3rd dimension. The idea that time is the 4th dimension is a myth and disinformation.

​@@Pond721 It does not exist in 3rd dimension. 3d is like a freeze frame - it can be well seen in some 3D graphic programs. Maybe we live in (at least) 4 dimensional universe... we can't move through time as we want - just like a hypothetical 2d guy drawn on a piece of paper can't move above or below the sheet.

@@deltadrom9013 Time is NOT the 4th dimension. This video is talking about spatial dimensions, which time is not. Time is it's own entity with it's own dimensions. Time certainly exists within our 3D space, we live spacetime, so we are technically already living in 4 dimensions. This video is only talking about the 4th spatial dimension, so in this case, time is not the 4th dimension, although it is A dimension.

yes thats correct but if "we" look at a 2d space in the 3rd dimension you see a circle, the stick man not

I mean would the stick man see anything? There is no width to the 2d world, so if the line had no width, how could it be visible?

@@sticlavoda5632 I guess the 2D man would see a color from each direction as he rotates around 360 degrees.

Hehe, he's got to be accurate. I might kill myself doing his equations on an experiment.

@@godisfraud You would understand it if you understood manifold geometry.

@@westonding8953 Oh yeah, manifold geometry. I had that right after History and before English.

True, I'm more confused and curious to know about how things actually look in 4th Dimension

Nope, I'm actually more confused 🤔

Impossible. Lower or higher dimensional matter has either never been observed or never been identified as such. The assumption that matter of our three dimensional space can directly interact with space of a different dimension leads to the believe that something like a Klinebottle as a physical object would actually be possible. If it's possible then it's only possible using higher dimensional matter. A Klinebottle as a space might be possible though, but any matter inside a space like this would be unable to identify the form of the space from within.

@@jk743 Well said.

In the video he gives example of how 2D person sees, but what is an example of 2D being? Anime? It doesn't make sense as well as 4D beings, Im sure it doesn't exists.

If you're reading it, it definitely puts more focus on the political/social commentary, but there are a couple movie adaptations. One of them, "Flatland: The Film (2007)" is on RU-vid in its entirety, and while the animation is a little lacking, it gives you more of the visual aspect.

Was thinking the same thing
