I played myself thinking I was smart enough to watch this video

you show me a 4D object in 3D world on my 2D screen and I try to understand this with my 1D brain

"the obvious answer is to take a 3x4 matrix and multiply by that" ah yes, just what i was thinking

I've been trying to "picture" tesseracts in my head and other four dimensional shapes and I feel seriously unwell.

When trying to find the longer side of the blanket

Me : okay brain, so what you got? My last active brain cells : Cube is a box

I think i remember seeing something that may help visualize the 4th dimension. Let us imagine a drawing of a stick figure holding a box, and a stick figure behind them. We in the 3rd dimension who look into this image can see everything. The contents of the box, and the stick figure behind them. The stick figures can only see in the 1st dimension, so the stick figure can only see lines and any lines stop their field of view. Hence why they cannot see through the box as they only exist in the X and Y axis. If a person in the 3rd dimension were to try to interact with the second dimension, like trying to stick their hand through a page, the stick figure would only see first your finger tips, then the rest of your hand coming through, and they wouldnt understand the sequence of what this ever changing thing, one line at a time. When it is really a hand. Let us then picture the same scenario, where we are holding a box and someone is behind us. We cant see whats in the box, and we cant see the person behind us. A being in the 4th dimension can see whats in the box, the person behind us, and everything else going on around us. It trying to interact with us in the 3rd dimension would be something similar to us sticking our hand in a stick figure's line of sight. It would come seemingly out of nowhere from some other spatial reality or rift and we wouldn't understand what is really happening.

I wouldn’t even begin to comprehend this when I’m awake, let alone watching this at 2am...

I understood the part when he said see you next time

*Before watching Me : I am confused *After watching Me : I am con and fused

Played this to see how smart I am, and discovered that im just a simple person .

After watching the video (watching, not understanding), I can say that I absolutely love the guitar playing in the background.

2:46 ah yes, the obvious answer. I was just about to say that

"So, there you have it..." No I don't...

I remember learning about this as a kid and I made it a point to try drawing a tesseract on all of my homework so that long into the future people would be perplexed as to why a kid was drawing 4d shapes 😂

This was the best one thus far. Thank you for your time and perspective.

This makes me feel like I live in Flat Land and an apple is messing with me

Trying to explain the 4th dimension is like explaining colors to a person blind since birth. There's no way to actually visualize is correctly.

One of the best explanations of 4D that I have heard. Thank You!!

I find it so fascinating that there are concepts, such as the concept of 4 or more dimensions or the concept of being dead, that completely short-circuit the human brain and we as a species are physically incapable of comprehending them.

Physics: How much of that did you understand? Me: No.

⚠ Brain.exe has stopped working.

I was so confident about my comprehension of four dimensional time space, and you just threw in so many new curveballs with the different types of physics, and the different types of ways that our physics could be perceived differently on other places

a minute and thirty seconds explained a tesseract with the best explanation I've heard

just when i thought i wasnt smart enough for this video i was comforted by the comments

Came here thinking I'd understand this. Now my brain's spinning like that tesseract

Such a cool animation to show this concept! Very interesting, thanks!

I had no idea what a 4D thing looked like til i watched your video...great stuff

*You lost me at "hello "*

I swear i never tried to understand so hardly about something in my life before

**Confused Oonga Boonga**

Years ago I had a spontaneous out of body experience and felt quite confused after. I swear I could see everything with a 360º vision. Inside and outside of objects at the same time. Couldn't really feel like I was separate from the objects I saw anymore. Whatever I focused on my attention on, I would become it. It was weird AF but it felt natural at the same time.

I'm watching this video in front of my parents, pretending I'm so smart.

2 mins in and he says "ok lets now get a little crazy." Buddy it was already crazy for my brain after 10 seconds.

As someone who lives in the 4th dimension I thought you did a mighty fine job.

This is awesome! I'm currently trying to program a tesseract into desmos and this really helped me visualize the math side of it. Great stuff!

If 5D cube was visible it’d be seen as a cube with Mental conditions

This video should be age restricted

This was very helpful in explaining why 2D representations of tesseracts look as they do! I've always considered the w axis to be time, or duration, and tesseracts are coherent sequences of expanding/contracting 3D cubes (a simple model, to be sure). Now I see people combine the x,y and z,w planes to fit the 2D monitor. Very informative; thank you ~

Awesome explanation. Thank you

Imagine fourth dimensional beings finding this and being like: “okay yeah kindergarten stuff”

I showed this to one of my coworkers and all he said was, "nigga what?", thus proving my theory that humans are not ready for this type of knowledge

thank you! i don't think i'll ever get close to understanding it, but you did a great job and now i understand a bit more...

It is fun knowing people were able to visualize this.

I'll just pretend to understand this......

I legit have no clue what you're saying, so when you said "the obvious answer" at 2:47 I wasn't happy

omg beautifully explained, loved it !

This is probably the first video I've seen with examples of the math used to make these models. Interesting

imagine 4th dimensional beings trying to understand the 5th dimension. we couldn't even comprehend a, v w x y z, axis. interesting none the less

*Loki wants to know your location* *Connection with Loki has been lost* *Thanos wants to know your location*

Up till now the best explanation I could find of 4d

still I dont understand it

I’m entering NTU’s faculty of mathematical sciences soon, and I understood everything you said till 0:05

3:43 "So there you have it." Me: searches for cat videos

This was, in fact, incredibly cool.

What happens when you try to draw the 4D dice on a 3D paper, like these drawings made half on the street and half on the wall. If you look at it from the right point it’s a perfekt drawing, but when you move it’s distortioned. I would love to play and try with this kind of thoughts.

I gotta admit, I really enjoyed making this video. I have always heard about the 4th dimension, but it wasn't until I actually implemented the double rotations that I really came to understand how cool 4d stuff can be! In particular, the projections from 4d -> 3d were hard to find on the internet, so I hope that helped someone! As always, let me know what you think. Thanks for watching / I'll see you next time!

I was simply listening to the band "tesseract" and somehow wound up here. Now my fascination with the geometric shape of the tesseract leaves me incapable of returning to whatever state of boredom I was in. Staring at the animation of the tesseract is about as close as I have ever came to experiencing being in a trance. This is certainly what Copernicus felt when he realized we're traveling around the sun, not the other way around. The concept of "perspective" takes on more and more importance the more I learn.

ouhhhh adding the concept of time really helped me! because it’s all at once. so that’s how you would see all those extras

Thank you so much, I was having some trouble sleeping but I feel sleepy now.

Cool, now explain like I'm 2

But to a 4th dimensional being, if one hypothetically existed, would see the rotation of the tesaract as a simple rotation, much like we would see if a cube was rotating.

i am just fascinated by 4D , this mind blowing mindfuck is amazing .. wish i could experience it just for a sec

I was trying to visualise this in my head this morning this is a good attempt at a 3d representation of a hypercube

Just give me a 4D object and I'll understand it.

But.. but.. I just heard Alan Walker Alone in 8D

awesome. Thank you for this

This isn't the content I wanted, nor was it what I expected based off the title.

I understand the concept of 4d but I cant visualize it in my mind.

0D - its a point = point 1D - is't an vector of points = vector. 2D - it's an vector of vectors = plane. 3D - it's an vector of planes = space. 4D - it's an vector of spaces = vector of spaces. 5D - and so one... Tesseract it's 4D cube? Really?

I came here from wiki wondering why there's 8 cubes in there and realized the 8th one is the outer most cube containing the entire thing when I saw the animation. Thanks!

how would the model look like if you stop half the way counterclockwise and then clockwise, as well as upmoving and down movement by halftime. Next step theoretically using all movements at once , is it possible to animate?!? Thanks for this video 🙏🏽

Me: *watches video* Me at end of video: So it's a cube within a cube connected with lines

I went to a "4D" movie once but it was just a guy in the theater would punch you in the face during the movie

I can *feel* my brain working hard to assimilate this as I hear it.

Ma'shAllah, it's a great concept of 4d.

AND I CAME TO UNDERSTAND INTERSTELLER !

So it isn't a storage for the Space Stone

This entire video is the epitome of "I like your funny words, magic man."

I like the superpower of space manipulation, so it’s something I think about occasionally, and I think I got something to _maybe_ explain part of 4D, though I’m not sure if it’s just 3D space still. So imagine; before you is a normal, wooden desk-with nothing but a flat surface sat on four legs. On that desk is a similarly normal piece of blank paper. That is 3D space. Now shift your view to the side, to where you can see where the desk and paper meet. The space between that desk and piece of paper is 4D space. From the view of 3D it’s practically nothing, true, but in 4D the distance between the two may as well be immeasurable. Think of it like the 4D plane is the ocean, the piece of paper is "floating" on the surface of the 4D plane right above the deepest part, the part just where the water meets ground again being that desk. Of course, this metaphorical ocean can’t be seen, so if you grabbed a pencil and "pushed" it down into that water, it would disappear, but if you had the ability (spatial manipulation) to see it and interact with it, you could "grab and pull" it back out. Like a magician twisting their hand and making an object seem to disappear, or pulling a object out from behind a person’s ear. Of course, this space is anywhere and everywhere, you could even "put" or "grab" a pencil from thin air, or from "inside" a cube. And I know this may sound a bit similar to the "house bigger on the inside" thing but I like to explain that through "density", increasing the amount of space in a space. For example; having a football field’s amount of space in a 5 foot area, so traveling through it would take the amount of time it’d take to cross a football field. I could honestly go on a rant of how I imagine to/explain to myself how space manipulation works using only more simple things, like using a pipe/tube to explain the looping hallway/area trick, but this is already long xD

THANKS 😊 for all the comments it really made me happy knowing that i wasn't the only one who doesn't get this

Do DMT and you will see 12 dimensions

It helped me a little bit: a square face is a line, a cube face is a square, a tesseract face is a cube. Each side of the tesseract is a three-dimensional cube! And there are a total of 8 of them in the tesseract, including: the inner cube (which is like hanging inside the big cube), the big cube itself, each cube if you rotate the tesseract left or right (there are 4 of them) and the two cubes at the top and bottom. And if the cube is rotated in such a way that you feel like your brain is melting, if you look closely, you can see as if the inner cube is being stretched over the outer cube every time.

Intriguing video which I understood thoroughly. I liked when the box went squonchy

This would be great to see in VR. Perhaps the rotation would make more sense when observed in 3d instead of 2d flat screen.

2:42 “If we have a 4 dimensional point, how do we represent it in 3D?” “Well, the OBVIOUS answer is: (shows super duper advance math equation)” 🥴

TIMECUBE has answered and explained all of these questions decades ago!

thanks for sharing the video. so knowledgeable

So I think I can explain the link that I had to make in order for this to make sense to you guys, and the part he kinda glossed over. Each group of edges corresponds to a dimension. A cube consists of length, width, and height edges. Length alone gives you a line, adding width makes a square, which is a series of lines, and then height makes a cube, which is a series of squares. The final dimension we have for the hypercube has the diagonal edge which links the innermost cube to the outermost, with a series of cubes in between these, like the lines in a square or the squares in a cube. Did that make sense? It would probably help to have a visual to point to, but sadly I do not have the software this guy used.

This comment section gave me brain damage.

Thanksfor the information. May I ask with what software did you make this video?

How to know if we are dealing with a different dimension ? Simply any exclusive change in that dimension will not affect the value of the other dimensions :so in a cube that has a 3cm length , width and height if we change the length alone to 4 cm we the width and height keep their 3 cm value , does this work with the tesseract model ?

Me: KZfaq: Hey kid you want a headache?

My DAILY BROWSING OF WIKIPEDIA 😂😂😂

This just left me with more questions while I didn't get an answer to the one I wanted.

So with this known, if we used a "3d" screen, like a hologram. Could we eventually find a visualized 4d object?

Me:*watches* Also me:*makes meme to cover the fact that I didn't understand a word*

One thing to note is that the projection of a 4-D hypercube animation onto a 3-D plane causes the lengths of some sides to appear longer. In reality each and every one of the sides of the hypercube is the same length in 4-D space.

Appreciated this 🙏💕

You made this so easy!! Thanks
