Something that really helped me is looking at the net of a tesseract. The net of a cube is a way to represent it in 2 dimensions, so the net of a tesseract is a way to represent it in 3 dimensions.
Its pretty difficult to explain 4d in a 2d environment, but in a 3d environment where we can "fly around inside" its pretty easy to explain... imagine a 3d space where f(x,y,z) now we are going to add another variable to make it a 4d space. We will call it a temperature map T(x,y,z,t) where x,y,z all mean the same thing and t is a temperature at a certain point. t will change nomatter any of the other variables. Thats the 4th dimension explained in a simple way.
We can represent 3D on 2D only because we know how 3D works, so, instead of seeing this 🧊 as a hexagon, which it actually is, our minds represent it as a cube

You can simply have the cubes appear one after the other, inbetween only having the end points, which will give you the illustration you are looking for with time as the 4th direction.
I like to think about two things. You in the third dimension looking at a two dimensional object (imagine it as a big piece of paper). You could see everything on two dimensional piece of paper if nothing is blocking you in the third dimension. You can easily solve a 2d maze And look around boundaries that a 2d creature would face. If you stabbed a 2d creature with a pencil, the 2d creature would see part of the pencil appear out of thin air and then get stabbed by it. If a 4d creature stabbed you, part of the 4d object would appear out of thin air and could easily just stab you in the heart without any contact to your skin
Time is also not the fourth dimension. Why would the first three dimensions be spacial and then the fourth one time? Also then the fourth dimension exists in the third, second, and first dimension. The third dimension doesn’t exist in the second dimension but it does (kinda) in the fourth dimension. Unless you imagine time as the 0th dimension as it exists in all of the dimension above it, but at that point why label it as a dimension as it still acts differently than other dimensions as a third dimension without time wouldn’t be the second dimension
Large misconception people seem to be getting from this. There are two different types of dimensions in physics, spatial and geometrical. Spatial refers to time and energy and the overall body we are describing, such as universes and possibilities. Geometrical refers to the actual shape itself, where you have lines, squares, and cubes for whatnot. They are not the same, and this video talks about geometrical dimensions not spatial. Also the existence of the fourth dimension isn’t proven, and by the very laws of physics as we know of them, can’t be proven as we cannot interact with the 4th dimension (geometrical one) since you can’t interact with things in a dimension above you.
I find it easiest to kind of understand dimensions above 3d as kind of arrays, so instead of asking myself how does something look like, I try to fix what is in a specified coordinate, extending the regular xyz position, with the 4th dimension coordinate for example setting what exactly is there. Or maybe as a system of numbering rooms in a warehouse: main corridor x: enter door 5; branching corridor y: door 4; branching corridor z: door 19; etc. etc.; final branching corridor...: door 7 -> room/what's at position/...
I always think of it as time, every single moment in time is another very small point of the shape, but because we experience time we can’t see all points at once, only if you live outside of time you can see in the fourth dimension
that’s what hg wells book the time machine was about. like time is a dimension, our consciousness just moves along it. also another analogy i heard was that time was like a string and a flame is moving along the string. the past is burnt out buy the future is still malleable
"we can't draw a fourth-dimensional object on a two-dimensional plane", he says, immediately after drawing a three-dimensional object on a two-dimensional plane. I'm just going to sit here, raising one eyebrow while sipping my tea out of a Klein bottle, like the Great Old One I am.
@@PuffyRhys What you see with your eyes is “2-dimensional”. They are next to each other - they’re not wrapping around objects. That’s why you will see a square when looking at a cube dead on - and you have to turn the cube to see that it is. Without shadows, you wouldn’t see a sphere. So, it’s not so much that the object on paper is 2-dimensional - if you had an eye beside the paper and it could see microscopically, you’d see a couple of lines of atoms revealing the depth of the pencil on the paper. It would be popping off the paper… and then if your brain was wired to mesh those images together to create a realistic, holistic image, you’d be seeing 3-D.
But you did draw the 4th dimension. 2D projection of a 4D hyper-cube. Just like how you didnt define a new direction for the 3rd dimension but drew a 2D projection of it. Or rather a cross section that displays 3 sides. Likewise if you position the hypercube the right way youll have 9 sides visible at once using your 2d capable eyeballs.

@@MaxEng1492 Time can exist in 2 dimensions too. Time is just when a dimension progresses. The 4th dimension would be an infinite amount of 3 dimensions stacked on top of each other which is not really possible to picture. I see what you are trying to say tho
We invented 2d, 3d, 1d and all of these, so we can invent the 4th dimension right? Well... if we get a sphere and move it up a 2d plane there will be a point that expands in a circle that gets bigger until the we reach the middle of the sphere, then it will shrink till its a point, and dissapear. So if we get a 4d sphere thru a 3d plane it will be a point that expands in a sphere that grows until we reach the middle and then it shrinks. In both cases the objects moved thru time and space, so 4d is 3d but comlex? A 4d cube is a cube that has 3d cubes as sides not sqares
We didnt invent dimensions, we live in the 3d world with x,y and z planes. Thats why we cannot do anything about 4d. Imagine a 2d object looking at a 3d object, as it cannot comprehend the z plane, the 3d object is seen as a 2d object. Similarly, if we ever can imagine a fourth plane, which is highly theoretical, we would still see it as a 3d object
My best guess for what a 4th dimension would be like an axis based on time. It'd be difficult to visualise because we can't go back or forth in time, but we could theoritically see it with a camera. But idk
I always thought the experience of the universe to be the fourth dimension. As in physicality + time = 4D. We can technically conceive of it; just not all at once.
The Thing is that we live in the 3rd Dimension and can unverstand how the 2rd and 1st Dimensions work could mean that a beeing in any Dimension can understand all the dimensions under them
Another way to understand it is by cross sectioning a dimension so you can view its dimension below. The cross section of a 3d object is a 2d plain.the cross section of a plain is a 1d line. The cross section of a line is a 0d point. The cross section of a 4d "thing" is a 3d object. In my mind, time running on a object is the 4d dimension, and if you cross section it, which means picking a fraction of this object existence, is its third dimension. So we actually live in a 4th dimension since time is passing by.
The fourth dimension is a concept and its called time, a best example of this is in the movie Interstellar, when the main protag found themselves inside a black hole and woke up in a tesseract, a higher plain of existance, the fourth dimension on which time itself is a physical touchable dimension, everytime he goes backward in direction of the tesseract, he goes back in time, everytime he moves forward, he goes forward in time.
I hate how everyone acts like they know what the 4th dimension is by using logic from the 2nd and 3rd dimension. I'm glad you just straight up said "it can't be done because our minds won't understand it"

You just won't be able to see the entire object because it's not something we can visualize. Although you would be able to see 3d sections of it. Kind of like how you can see 2d sections of a cube if you cut it up into thin slices
@Thegoldmokey exactly

the problem with 4d is that, we don’t know which way to we’re supposed to go, while we can make 4d with two cubes, we just don’t know how to do it
I think you got the wrong idea. 4D is an expansion of 3D, there's no concrete direction.
If the AC Repair school would just tell us the direction they keep secret we’d be able to see the 4th dimension
Something that really helped me is looking at the net of a tesseract. The net of a cube is a way to represent it in 2 dimensions, so the net of a tesseract is a way to represent it in 3 dimensions.
Its pretty difficult to explain 4d in a 2d environment, but in a 3d environment where we can "fly around inside" its pretty easy to explain... imagine a 3d space where f(x,y,z) now we are going to add another variable to make it a 4d space. We will call it a temperature map T(x,y,z,t) where x,y,z all mean the same thing and t is a temperature at a certain point. t will change nomatter any of the other variables. Thats the 4th dimension explained in a simple way.
All this shit just hurts my brain

I think in the 4th dimension you can see the other side. You see all four sides of a cube…from another angle/viewpoint. Most assume that angle is through time past, present, and future. But as the flatlanders couldn’t not wrap their minds around height or depth. That someone could look above and see everything.

Wrong 4d is not time 💀 we have no idea yet what is 4d or higher
If you can’t understand: each time the shapes duplicate, we look at them from a new dimension, so he straight line and the line above show the 2nd dimension cause up and down are the two dimensions in the square, similarly we need the cubes to align in a 4D angle in order to connect them to their end points and make a 4D shape, but we can’t make a 4D area cause we are in the 3rd dimension.
Damn that’s literally the best way of explaining it ever. I instantly got it, although I’ve always kind of figured this was the case. Thanks!

You can simply have the cubes appear one after the other, inbetween only having the end points, which will give you the illustration you are looking for with time as the 4th direction.
I like to think about two things. You in the third dimension looking at a two dimensional object (imagine it as a big piece of paper). You could see everything on two dimensional piece of paper if nothing is blocking you in the third dimension. You can easily solve a 2d maze And look around boundaries that a 2d creature would face. If you stabbed a 2d creature with a pencil, the 2d creature would see part of the pencil appear out of thin air and then get stabbed by it. If a 4d creature stabbed you, part of the 4d object would appear out of thin air and could easily just stab you in the heart without any contact to your skin
Also how a 4d dimension would be infinitely stacked 3rd dimensions on top of another in a direction we can’t perceive
Time is also not the fourth dimension. Why would the first three dimensions be spacial and then the fourth one time? Also then the fourth dimension exists in the third, second, and first dimension. The third dimension doesn’t exist in the second dimension but it does (kinda) in the fourth dimension. Unless you imagine time as the 0th dimension as it exists in all of the dimension above it, but at that point why label it as a dimension as it still acts differently than other dimensions as a third dimension without time wouldn’t be the second dimension
Large misconception people seem to be getting from this. There are two different types of dimensions in physics, spatial and geometrical. Spatial refers to time and energy and the overall body we are describing, such as universes and possibilities. Geometrical refers to the actual shape itself, where you have lines, squares, and cubes for whatnot. They are not the same, and this video talks about geometrical dimensions not spatial. Also the existence of the fourth dimension isn’t proven, and by the very laws of physics as we know of them, can’t be proven as we cannot interact with the 4th dimension (geometrical one) since you can’t interact with things in a dimension above you.
I think its about the fourth space dimension, not time.
I find it easiest to kind of understand dimensions above 3d as kind of arrays, so instead of asking myself how does something look like, I try to fix what is in a specified coordinate, extending the regular xyz position, with the 4th dimension coordinate for example setting what exactly is there. Or maybe as a system of numbering rooms in a warehouse: main corridor x: enter door 5; branching corridor y: door 4; branching corridor z: door 19; etc. etc.; final branching corridor...: door 7 -> room/what's at position/...
Exactly my thought. That is why 4d cube thing not actually 4d.
I always think of it as time, every single moment in time is another very small point of the shape, but because we experience time we can’t see all points at once, only if you live outside of time you can see in the fourth dimension
that’s what hg wells book the time machine was about. like time is a dimension, our consciousness just moves along it. also another analogy i heard was that time was like a string and a flame is moving along the string. the past is burnt out buy the future is still malleable
Are you guys high right now?😶🌫️
When I see the 4th representation I imagine it as if the cub is moving through time and the lines connecting the two cubes is time connecting them
That's good but wouldn't that mean time was the 4th dimensional direction?.

I’m with YOU. And what we visualize has more dimension than what we see, and what we see has more dimension than that piece of paper…
The three-dimensional drawing is still two-dimensional
@@PuffyRhys What you see with your eyes is “2-dimensional”. They are next to each other - they’re not wrapping around objects. That’s why you will see a square when looking at a cube dead on - and you have to turn the cube to see that it is. Without shadows, you wouldn’t see a sphere.
So, it’s not so much that the object on paper is 2-dimensional - if you had an eye beside the paper and it could see microscopically, you’d see a couple of lines of atoms revealing the depth of the pencil on the paper. It would be popping off the paper… and then if your brain was wired to mesh those images together to create a realistic, holistic image, you’d be seeing 3-D.

As 3d creatures with 2d vision I think in order for us to really understand what 4d looks like, we have to have at least 3d vision
But you did draw the 4th dimension. 2D projection of a 4D hyper-cube.
Just like how you didnt define a new direction for the 3rd dimension but drew a 2D projection of it. Or rather a cross section that displays 3 sides.
Likewise if you position the hypercube the right way youll have 9 sides visible at once using your 2d capable eyeballs.
Simply put it our eyes and minds can see or imagine 4d

Your turbo good at explaining
I found this all by myself as a 13 year old, I basically went,
"Huh, if stacking 2 squares gives me a cube, which is of a dimension higher than the squares, then shouldn't I get a 4th Dimensional object by stacking 2 cubes?"
Which is quite some thinking for a child and my concepts weren't *entirely* wrong.
This man os going to ascend do the higher Dimension when he unlock the secrets of 4D
Well when you drew the cube you can’t define another direction that is perpendicular to the others too. You are drawing on a 2d paper…

@@restrictednuggies of course he's not wrong. But he didn't mention that the third dimension in the diagram is also not a new direction because it's on a 2D screen.

The second he said fourth dimension my brain just said “IS MY OwN MAnSIon”
0-D: A concept of shape (non-existing)
1-D: One axis (x,y,z)
2-D: Two axis in different directions (x,y, or other axis combined)
3-D: Three axis in all directions (all of x,y,z)
4-D: Overlapping 0,1,2,3 dimensions in all axis (x,y,z)

basically a tesseract isn't a 4D object but it's the closet representation we could get
Man the 4D update is going to be awesome
It already exists, it's called time.
We invented 2d, 3d, 1d and all of these, so we can invent the 4th dimension right?
Well... if we get a sphere and move it up a 2d plane there will be a point that expands in a circle that gets bigger until the we reach the middle of the sphere, then it will shrink till its a point, and dissapear. So if we get a 4d sphere thru a 3d plane it will be a point that expands in a sphere that grows until we reach the middle and then it shrinks.
In both cases the objects moved thru time and space, so 4d is 3d but comlex? A 4d cube is a cube that has 3d cubes as sides not sqares
We didnt invent dimensions, we live in the 3d world with x,y and z planes. Thats why we cannot do anything about 4d. Imagine a 2d object looking at a 3d object, as it cannot comprehend the z plane, the 3d object is seen as a 2d object. Similarly, if we ever can imagine a fourth plane, which is highly theoretical, we would still see it as a 3d object
Who told you we invented 3 spaces lmao that's just how the world works we just took said spaces and made stuff with them
Wow thank you for the information
can't wait for the update when they gonna add 4D
you could use time as your fourth dimension instead, moving along time you see new parts of it but you've all already seen that
Rinnman’s Plane is the best representation we have of a 4d space. You have to gradient it in order for it to be comprehensible, though.
If I were to try and imagine a new direction I would view it as an object expanding. There I solved 4d
This 3d representation of a cube is effectively what the shadow of a 4th dimensional shape would look like
My best guess for what a 4th dimension would be like an axis based on time. It'd be difficult to visualise because we can't go back or forth in time, but we could theoritically see it with a camera. But idk
I always thought the experience of the universe to be the fourth dimension. As in physicality + time = 4D. We can technically conceive of it; just not all at once.
Good Job 👏👍
this man is an genius
The Thing is that we live in the 3rd Dimension and can unverstand how the 2rd and 1st Dimensions work could mean that a beeing in any Dimension can understand all the dimensions under them
If you have a sphere and you put 4 equidistant lines that extend to infinity, you can make a 4d graph.
Another way to understand it is by cross sectioning a dimension so you can view its dimension below. The cross section of a 3d object is a 2d plain.the cross section of a plain is a 1d line. The cross section of a line is a 0d point.
The cross section of a 4d "thing" is a 3d object.
In my mind, time running on a object is the 4d dimension, and if you cross section it, which means picking a fraction of this object existence, is its third dimension. So we actually live in a 4th dimension since time is passing by.
Oh!! we kept going in lines and never went around so maybe that’s the thing
But Einstein said that basically 4th dimension is time ⏰

The fourth dimension is a concept and its called time, a best example of this is in the movie Interstellar, when the main protag found themselves inside a black hole and woke up in a tesseract, a higher plain of existance, the fourth dimension on which time itself is a physical touchable dimension, everytime he goes backward in direction of the tesseract, he goes back in time, everytime he moves forward, he goes forward in time.
