Can Life Exist in 2 Dimensions Instead of 3D? Amazing 2D Life Test!
HTML-код
- Опубликовано: 16 июн 2024
- Real-life flatland! In this video I use micro-thin layers to simulate two dimensions to see if life could exist in 2 dimensions instead of 3. I use my drawing on water technique to show you how weird a two-dimensional world would be. Then I show you some other problems in 2D such as having a digestive tract. Then I talk about Conway's Game of Life and if that is truly alive or not.
Also, watch me hit 1 millions subs! Thanks everyone!

In 2D, they cannot see inside a circle without breaking it
In 3D, we can see inside a circle but not inside a sphere
Which means in 4D we can see inside a sphere without breaking it
Right?
Yes you are right! A 4D being would be able to see inside of any three-dimensional object without opening it. Just as in three dimensions we can see inside of a circle without opening it but two dimensional creatures cannot see inside of the circle like you mentioned

Can there be a llfe in 3 dimensions? As we can see -- no organism without tubes in itself can sustain life in this miserable dimension....
I remember once, me and a few friends discussed that, for a 2D being, us interacting with them would amount to something "popping in and out of existence." So, to them, we'd be Eldritch Abominations, Ghosts, Demons, etc due to not being able to quite explain what they experienced.
That'd be a good setup for some Cosmic Horror story.
What if our Ghosts are actually 4th dimensional creatures?
do you mean those 2d projections of a slice of human, including the organs? or do you mean a line

Carl Sagan did an awesome demonstration on life in two dimensions. First of all he essentially said that no matter what shape the life form is in, all it would be able to see in the world is straight lines with absolutely zero thickness.
He used paper shapes for the example and mentioned that even paper (or really any object in our world) is not a perfect example because it does have some thickness

There could be "tubes" if it was fitted with several "hooks" making the tube a serie of "airlocks" that would open and close successively. But otherwise for digestive processes, it's probable the best solution would be to vomit the end-product... Sorry. But this is how it'd work at the cellular level, and I'm sure it would be the same macroscopically.
This was my very first thought when I read of the same "digestive tube" problem in one of Stephen Hawking's book.
The analysis in the video (and in Hawking) is formally right, but it lacks imagination...
It does work in macroscopic animals. Jellyfish, for example. They are single orifice animals.
What would vision be like in a 2 dimensional world? Wouldn't everything we see be a line?
Yes I should have mentioned that! Vision would be just seeing lines you wouldn’t be able to see any shape, just lines. Kind of like in three dimensions we really can only see a two dimensional
Yeah, a line. But there would still be things like perspective and colors and you could still make out the shapes of things. Like the way you can tell what a cube is in 3D even though the image formed is 2D.
Deba Kun Well, you would not be able to see at all. Light is a wave that propagates in three dimensions (the wave vector, electric, and magnetic fields are all orthogonal to each other), so in a two dimensional world light could not even exist.
Daniel Espinosa Gónzalez *light as we know it
The answer to all questions you might have is Flatland. It's a definite must see in my opinion. I haven't read the book yet but I heard it's good too.
5:03 no, that's not true. You can still have a tube system the say way that, for example, canal locks like the ones in the Panama Canal work, alternating one another on opening anc closing while the element passes and is processed.
We're not just open tubes, the same way in nature membranes aren't just permeable all the time.
All I heard was BLA BLA tubes BLA BLA closing BLA BLA
If the tube where nutrient comes in, oxygen comes in, and waste comes out where all the same hole, then the organism wouldnt have to be split in half. It would be very wierd to shit out of the some.hole you eat food with, but it might work.

Canadian Professor Alexander Dewdney wrote a novel on the topic, The Planiverse. It talks about life in a 2D world with 2D physics and how things might work. Gets into a lot of detail, including talking about how people climb over others, and how zipper organs are used to make digestion work, and proposes electrical systems and all kinds of technology. Good read if you're really interested in the topic.
abj I agree , it's a great book that really helps you understand the full concepts of 2d existence.
The biology was extremely interesting, as was the concept of engineering gears on a 2d surface.
For a 2-dimensional creature to climb over something, it would have to be able to ascend into the third dimension. A 2-dimensional being would be aware of forward - backward, and side to side. Coming up against an obstacle, it would only think to go around it and not even contemplate the option of climbing over it, as the concepts of down and up are beyond its comprehension.
Mark Lane271 Why do you assume up and down are the ones that out of question?
Most people think of 2D as up, down, left, right
You know, like a 2D game
Seems strange you've randomly decided that up and down would be the nonexistant directions

The whole premise of this video was covered back in the 80's in a book called "The Planiverse", by A.K. Dewdney, even covering the topic of a digestive tract that bisects the body. Pretty fascinating book.
I just posted the same thing. Guess I should have scrolled before posting. Still, it IS a good book. Glad I'm not the only one who read it. :-)

2 dimensions are always imaginary ! For example when you draw a circle, a circle is always an imaginary concept ! No matter how small will be the height, it will become a cilinder in 3 dimensions !
Shadows and 3d objects intersections with planes are 2d
ya. shadows are 3d. photons are 3d.
@@indianministryofilluminati3531 Well shadows are created by photons but actually only occurs on surfaces which makes it 2d. Anything that can exist entirely on a surface or face is 2d.
Nope. I'm Charles Darwin that doesn't mean I don't love physics I only love biology. nooo. But whether shadows are 2d or not is a great point for debate. I'm just a teenager. Not a scientist. I don't have much knowledge but ya this is a great point of debate. Let's ask vsauce!
@@indianministryofilluminati3531 I'm going to have to disagree. But I think to say that a shadow is 3d you must say that shadow has volume. No one will say shadow has depth or volume. Only surface area. Therefore it is 2d
You could live as a 2D being if the food was ingested and digested from the same opening.
There's a reason we don't have acid in our mouths
2 way digestive tract?
Yes, that's the only strategy for 2D animals, and many 3d animals do that too.

Sometimes and idea about 2 dimensional universe pop up in my head and every time it is very entertaining thought, because there is much aspects you can think of about 2 dimensional being and at the same time it is always super unusual and surprising, so this is a great video, but it is absolutely not enough
I send your videos around all the time. Great work!
Wow! Finally one million subs! It's just yet another round number, we made it possible step by step, one by one though.
Using your idea of no tubes, wouldn’t no life be possible? Because cromosomes, cells, or even atoms are in the 3rd dimension so they would not be able to be 2D world right?
I love your videos,
great job man
Actually, a tube can work in two dimensions. Everything has zero depth, so that means that you can have as many layers of “zero” as you need. All these layers still ad up to zero.
so? terraria logic? objects in the backround and objects in the front?
well, this would be more like as 2.1D
@@igorjosue8957 I think that is how it would work if 2d was real. It is hard to understand.
What if the tubes are shaped in such a way that they interlock with each other, therefore still allowing food to be digested within the body?
Oohh satisfying!!! Nice video 👌👌👌

It's nothing new. Flat Land was written in the late 1800's, and Conway's game of life has been around since the 80's.
There's also the book The Planiverse, written in the 80's which went into detail of how a 2D universe would have to work, covering biology problems (including the one in the video), and more subtle problems -
Taking a description from Wikipedia -
_"The Technology of Arde is explored in great detail. For example, all houses are underground, so as not to be demolished by the periodic 2D rivers; nails are useless for attaching two objects, tape and glue are used instead, most Ardean creatures don't have deuterostomic digestive tracts since they would split into two, and have instead evolved alternatives; and even games such as one-dimensional Alak, everything is designed to work in 2D. An appendix explains some fundamentals of Ardean two-dimensional physics and chemistry."_
0:116 Actually, up and down is Y, not Z. Z is forward and back.
On the issue of tubes, I have a two solutions. One, instead of having a digestive track you can just have a single hole. Lots of real organisms do this. The other solution is that you have transient tubes. The digestive track is divided into chambered, where each chamber has a seal that acts like an air lock. If all the seals our open, then a 2D being will split in half, but by only one being open at a time food can pass through the chambers and go from one end of the body to the other. This also isn't too radically different from our own digestive system as it's divided by sphincters, though I'd think you'd need a different sealing mechanism to be strong enough to keep a body from ripping in half instead of just keeping fluid in separate chambers.
A million! Epic, thanks for all the science+
Congratulation !! 👍
3:03 So THATS why dora never goes the obvious way!
this was actualy really interesting, could you do a video explaining the 4th dimension and what life would be like in it
*actually
This dudes math/ geometry makes my head hurt but I can’t stop watching.
I remember Carl Sagan doing a similar experiment and I've always had a problem with it. No matter how absolutely flat an object that that can only move in the x and y axis is, it still has a measurable z dimension.
These are simulations not evidence. It's true that nothing within our universe can be anything but 3d but we can simulate 2d by making the z axis inaccesible
is there a video of 4 Dimensional life ? if not can you make a video like that ?
that part at the end... was AWESOME!!!
Congratulations! And thanks! It's reassuring to know a decent number of folk desire knowledge and learning!
6:12 - After this part I started to feel like humans are proof of life in the 2nd dimension because we follow those rules.... Am I actually a 2 dimensional being¿! 😲🤯
😂
My whole life I occasionally have memories of a 2 dimensional world. For over 20 years!!
Imagine if we are in Earth's game of life
Congrats with your one mil man!!🥳🥳🥳
I can now revive my anime waifu because of this
A two dimensional object is beyond current reasoning. atomic structures are three dimensional, an object Even an atom thick has a third dimension. So regardless how thin an object it is in our universe it will always have a third dimension. So the atomic structures in a two dimensional plane would have to be entirely different than the ones we know and understand today. In other words it's beyond our comprehension.
Yes but we can comprehend 2D and how if 2D beings existed without problems, how they would see things .
Wow I feel kind of special that I am one of you one million subscribers lol. Congratulations I hope you get a million more 😀
I had to scrape my brain off the floor after this........great video
2:25
Prooooooof the earth is flat
If you actually think that the world is flat, your weird
And the world is not green it's blue
I don't think life can exist in 2D. Even atoms are 3D. 2D is basically nothing since the line is infinitely small which nothing can match.
The 2 dimension world isnt in our universe but in another universe where the laws of physics are probably different
Hagios Lukas Marihot Sianipar , I agree, a two dimensional world can only be viewed from another dimension. A two dimensional world has no thickness, thickness requires a third dimension. 🤔
But aren't atoms or at least sub atomic particles zero dimensional?
Hagios Lukas Marihot Sianipar the 4d creatures are probably hypothesizing the same thing right now
Shadows are 2D
4:40 it's more interesting to know that 2D will perceive impossible connections where digestive systems seem to function or maybe even seem to move randomly from one void to another void before ending up being pooped out.
Where we would fully see the 3D connections as a whole
I feel like at least some of these problems would be fixed by evolution.
I love your videos, thanks for taking time to create and share your knowledge.
No they wouldn't because evolution only works when life already exists. If life doesn't exist, there is no life to evolve.
3:17
why is nobody talking about the edit❓
Yeah it was weird
There’s a hand below it it think it attracts the marker
Well, a 2 dimensional universe would form much differently from ours, the entire universe would have a different physics system, creature behavior, and so on.
And it would be a potential threat to our superior 3d ways of life, we'd have to destroy them before they destroy us.
So cool watching that 1million ticker. Great videos
Congrats for the 1mill sub. Can you have tubes in 2d world if the tubes are a bit more complex? Like if the end of the tubes are open but inside there are a multitude of sticky valves that open and close passing the object along as it opens and closes.
