TED-Ed - Flatland 

this is most likely what bill cipher's dimension looked like

"Your brother is expendable" - A Sphere 2999

"You think those chains are tight? Imagine living in the second dimension. Flat minds in a flat world with flat dreams. I liberated my dimension, Stanford, and I'm here to liberate yours." - Bill Cipher

This story/concelpt has become significantly more popular thanks to the funny Illuminati triangle man.

I feel sad for people who have the "That's impossible because i can't comprehend it" attitude. That guy lost his sense of imagination, wonder, and awe.

A Square: I need an adult! A Sphere: I AM an adult.

“Do you know what spawned your existence?” *“EDWIN ABBOTT ABBOTT HAD A GOOD IDEA”* -Bill Cipher AMA, Disney’s Gravity Falls

This was a film that my math teacher in middle school showed us. I remember one particular scene that felt straight up like an acid trip.

"Hey guys for a prank."

1:54 Oh boy. I sure hope this “little boost” doesn’t cause any chaotic, cataclysmic doomsday to a whole dimension. Or anything.

Bill cipher be destroying euclidya with this one 🗣️🗣️🗣️🗣️🔥🔥🔥🔥🔥

why do i feel like alex hirsch saw this while coming up with bills origin

Sphere: nice day I lov- Hyper cube:AYE WHATS ALL THIS THAN AYE MATE ID LOVE ME SOME FOUR DEMENSIONAL TEA AND CRUMPETS AYE LAD?

This is actually a really sad story because at the end (SPOILERS FOR FLATLAND WARNING) the square gets arrested for being a "madman"

I'm intrigued by things like this, but It makes my brain hurts to think about it.

@4:05 For clarity, that is not a hypercube. It’s impossible to show any object greater than 3 dimensions in 3 dimensions.

I read FLATLAND years ago but listened to it as an AUDIOBOOK last week to remind myself of key concepts. This video was a wonderful addition to the FLATLAND lore. This book is a seed-idea that will one day blossom into the cornerstone of something great!

Wait, is this resurging because of Bill Cipher? 😭

I just finished reading Flatland. It was a fascinating story. I highly recommend it.

So technically 4D people are magician to 3D people ? Neat

The 3D sphere can go wherever/however he wants in the 2D world (violating the physics in the 2D world's perception) 4D beings can do the same in our 3D world e.g going through walls, teleporting objects, and so on, which we perceive as non-sense or foolish (denying the existence of such beings or scenarios) that has to be the closest we can get to explain spirits, ghosts, etc. Not believing or being offended on the existence of higher dimension beings compares an individual to a 2D square.

Skip this and watch the 2007 film. It will take a few repeat viewings but when it "clicks' it will be in some minor yet important ways utterly life changing.

In the beginning of the video, it states that the Flatlander can only see 1 dimensional. So if the Sphere lift the square to the 3rd dimension, it will still only see 1 dimentional. It won't be able to even recognize its own 2 dimensional world and friends from this angle. To it, the whole world has gone wacky!

Bill chiper ah dimensions

"IVE GOT SOME CHILDREN I NEED TO MAKE INTO CORPSES!👹👹" Head ahhhh 💀💀💀💀💀💀🙏🏾🙏🏾🙏🏾🙏🏾🙏🏾

I don't even want to think how confused you must have been when one day your 9-year-old animation suddenly exploded in popularity because of a cartoon triangle man xDDD Anyway, it's a very cool animation, I really liked it ❤❤❤

No way. The animator!

Watched Flatland in my math class and I am now intrigued on if there could actually be a 4th dimension. And/if there is a 4th dimension how big is it? Where is it? The observable universe is so large is there more to space than the 3D world we live in? What’s inside a black hole? Is there life anywhere else we can reach in the universe? All questions in the rabbit hole I’m digging into for the movie flatland

Like in your hypersphere example, what if that sphere represented our universe? That could explain it's creation to a degree, could it not? It explains why the universe is continuing to grow, and how some scientists believe the universe will eventually start shrinking and collapse back in on itself. Maybe the universe is just a 4dimension object passing through a 3dimensional plane of existence.

Astonishing design and animation :)

funny yellow triangle man

I just listened to this book on RU-vid. It is defiantly a relic of its time with how it portray women characters. Beyond that it is a good book with the concepts to get you thinking.

We are in the third dimension and can see what a two dimensional world and even one dimension can look like. It doesn't mean there's lives and worlds in higher and lower dimensions. Possibilities can be endless but all in theory.

This three-dimensional video, presented on my two-dimensional phone screen, is trying to explain a fourth dimension to my one-dimensional brain.

DUDE!! I KNEW the movie reminded me of something! Thomas was alone! And then i hear that first “DING” in the video and I know instantky where thats from! So cool you used some of the soundtrack for this

the ghostly spiritual world is most definitely 4D

Pretty sure this is what's being experienced at Skinwalker Ranch in Northeast Utah. Spheres popping in and out of visual detection.

What if dark matter was actually 4th dimension matter? That would explain why we can see its influence, but can't detect it..... in a similar way that a sphere can influence a 2D world, but the 2D inhabitants can't detect it.

Is it a coincidence the equilateral triangle is yellow?

Cale, this is some great design, animation, and execution!!! Thanx 4 sharing =)

what an amazing video. so well done man. you deserve more subs.

4D People watching this be like: Yo im gonna kidnap you and take you to my world

There was a cartoon, when a boy and his dog landed on flatland with a yellow-rubber-spaceship. I cannot find it anywhere. Anyone knows this?

I want to use this concept for angels in my lightnovel I want to write. It seems very interesting as it explains why biblical accurate angels look the way they are. Of course that's just my religious bias and probably should be taken with a grain of salt but still something interesting to think about.

0:28 oh no bill cipher

If you imagine the hypercube as a bunch of progressing cubes connected by parallel lines it makes more sense. Just as a cube is a continuation of infinite cross sections of squares, so too is a hyppercube infinite cross sections of a 3d object in space and time. So that undulating snake shape is actually a square being represented in each planck moment in our universe. The 4d observer should, theoretically, be able to interact with any "time" or "space" within the range of that object. That is to say, If i stick a 4d finger i a 3d object or timeline, i would, to the 3d observer, appear as if i'm appearing out of no"where", possibly for indeterminate durations, and then disappearing. It might not know that I appeared in its "future", but it might know i appeared in its "past". In 3d, we percieve 4d as a 2d flatlander percieves the "glow". We know there is something that moves along an unkown axis that we can't contol, we call it time. We can't move "in and out" through time, though. A being trying to show us how to step into 4d would probably be showing us the entire timeline of our universe, from beginning to end, as one long, undulating snake in its dimension.

But are there any sentient 2D worlds or communities that we know of???

Hey... that music is from Thomas was alone

Once i saw a cartoon on my tv protagonist visits a 2D planet and picks up a 2D human and transforms it into a 3d and scared

What is this music called, I just love it!

Also in that book the Flatland women were lines for some reason

Most if the shapes: this is fine Vs triangle: MAN I HATE THIS WORLD IM GONNA DYSTORY THIS!!!

Thank you. Makes me think of persons who deny the existence of Yahweh and angels

So, in the movie about flatland, (I don't know how source accurate it is) the square is almost killed by gravity, a fundamental principle of science. This means that the difference between dimensions in geometry is direction, while scientifically, it is physics since there is no gravity in flatland. We have 4 fundamental principles: gravity, electromagnetism, strong nuclear force, and the weak nuclear force.(I think) If flatlanders lack gravity, then they are kept to their dimension by another, let's pick electromagnetism. The 0'th dimension, of pointland is only held back from lineland by say the weak nuclear force. The planets can't be secured with electromagnetism in most cases, so there needs to be gravity, as without is, we would float to hyperland. In hyperland, gravity alone cannot keep the beings from wandering to the 5'th dimension. The dimensional wandering would be problematic because, as we saw, beings of lower dimensions can be killed with the higher physics. In conclusion, I'm overthinking things.

So that's where all the Mathiverse thing came from, huh.

Thomas was Alone, wow, what a weird first thought to have

I love flatland

ANYONE WHO HASNT SEEN THE FRICKIN MOVIE WATCH ITTTT!!!!

There is a sequel to "Flatland" called "Sphereland: A Fantasy About Curved Spaces and an Expanding Universe" -- author Disney's Burger.

Upward, not northward

Did the music composer of Terraria make this guy's youtube audio?

I was thinking of this this morning Sept1 2024

The streets will flow with the blood of the non-believers.

I love this , Thank You so much

I knew this as a child. I got drugged.

The most sides mentioned in 2d in flatland: 360

That broke my brain 🧠 😩 😫

Keep up the great work

Can we just vibrate fast enough to get notice ?

But....a whole book?

If we see in 2 diamensions then 4 diamensional beings see in 3d

28 flatlanders downvoted this video...

W H Y D I D Y O U D O I T ?

Flora nolan... She got there..? As her dad set her puzzle game..

Thank you for your awesome video

In a similar manner, a multi-dimensional Creator God becomes a 3-dimensional man so he can enter into his 3-dimensional creation.

Well this blows my little mind lol

Very fun friend 👍✊

Thomas Was Alone music?

- ----- - guys, don’t you recognise me?

If creatures on flatland can see lines then it's a 3D space, cuz a line has thickness.

This is not shocking to me at all.. human does have limitation.. theres colour and sound wave that we cannot see and hear but it doesnt mean it is not there.. Theres a lot more to this life than we could ever imagine

HIII!!!!!

i need the soundtrack for this vido so bad

not 5th, though, that's just silly

You mean uclidia

This is good.

Thank You

Now i get it

"A WOMAN!"

It’s true I was the tesseract

Terraria music in the background?

Where is my holographic mobile right when I need it?!

0:16 EEEEEEE

(waiting for 4d hypersphere to carry me away)

Colour Revolt brought me here

Guys hi

Wait So What do 1st Dimention Lines See?

4d is time dimension
