There's SCP-6011 which is about 2D society and how they function. It's a bit of an interesting read and can probably give some views on how 2D people would react
This really does cut straight to the point of why this is a dumb comparison. Even if you only existed on an X and y plane, the very nature of perspective would dictate you must see in 3 dimensions. If there is a 2d entity, it wouldn’t see anything in any perspective.
@@NateTheOhioan I like to imagine this is how nth dimensional entities have fights. It's quite humorous to imagine lol. They keep ascending to the next dimension just to one-up their rival.
@@t900HAWK Then who knows if creatures could exist in the 4th dimension. Everything is hypothetical here. Don't say like "well we dont even know if vision work in 4d"
@@Bouldergoat I mean you are right factually, but this whole video is assuming vision "works" in 4D, right? We are here imagining "How Would Our World Look In 4D?". That's in the title. Why would you have to hypothsize "doesn't work"? If it is the case, this video would not even exist in the first place. People like you have a questionable habit of supporting these nonsensical comments and ideas, "lighting up" unecessary arguments on the internet. Please have a mind and stop writing these kind of comments
The better example is: A 1D guy does not see anything except a dot, So a 1D guy's eye is 0D A 2D guy does not see anything except lines, So a 2D guy's eye is 1D A 3D guy sees one glance/2D at a time, So a 3D guy's eye is 2D That means 4D people see the back, front, right, left, top and bottom at the same time
@@wallyhuncho2998Not quite. A 360 video can't see through walls, it's just 3D but in a 360 angle. 4D vision involves being able to see *all sides* of a 3D object, just like we can see all sides of a 2D object. A 4D person looking at a box, would be able to see everything outside the box, inside it, and see it's thickness, *at the same time.*
Most people look at a tesseract and have zero idea what it is. It’s attempting to express to you by rotating in on itself that you could see inside of the cube from the outside. In this scenario you could see all sides of the wall and through it
Those tesseract animations are usually the next-dimensional equivalent of what a 2D being inside the page/screen would see of a cube's animation. If they could distinguish it well enough (this is tricky, because from within the plane of the picture they can't see past solid lines), they'd see various quadrilaterals passing through one another instead of an arrangement of squares rotating around one another-the screen doesn't have depth, and they don't have the ability to conceive of the "left and right" dimension where the square sides of a cube pass by one another without one going _over_ the other. So no, the hypercube "rotating in on itself" is not depicting that you could see the inside of the cube-it's just the cubic sides of the hypercube passing by each other in a direction the screen can't depict and your mind can't imagine.
Well technically we have never seen a real living 2nd dimensional being so maybe they can't see us as well which in turn means that any living being on a different dimensional plain cannot see eachother but are always close to eachother
Simple answer: each dimension is made of the dimension before it, excluding the 1st dimension. The 3rd dimension is made out of 2d figures, and the 4th is made out of 3rd dimensional figures. Hope this helps!
I mean we are actually 4D creatures. Think about it. 4D is space-time, meaning the “space position” (from my understanding of space time, correct me if I’m wrong I’m just a kid) and time both exist. Now what is space position? Space position is like having a stretchy mesh made of strings. If you glue a marble to a specific part of the mesh, say the 10th row and 14th column, then stretch the mesh making the strings further apart, the marble will stay in the same space-time position, the 14th column and 10th row, yet its 3D position will change. This is a great way to visualize the expansion of the universe. Lets get back to the question though. We are 4D creatures because we experience 4D anomalies like space and time. If a 5th dimension existed in our universe and we didn’t experience, we wouldn’t be a thing. We can only visualize what a 5D or 3D or 2D universe would look like but at the end of the day, it’s always 4D. Everything we experience REQUIRES length width height space and time. Otherwise, it wouldn’t have any properties at all. Also if there are any scientists out there and I’m saying some ooga booga stuff please call me out. I’m just some 8th grader interested in science.
It's not really 'through' but around. They see things in 3 dimensions just as we see them in 2 so they'd be able to peak around the sides of every particle
@@Asdqazasdqaz nah because they don’t see through everything they just see around it in the way that we can see around the wall between Josh and Molly.
How can you comprehend something your senses are incapable of picking up and brain isn't capable of processing. There are colors we can't see, but other animals can, but because we can't even see these colors it's virtually impossible for us to visualize them in our brain because our brains aren't built, or trained to.
I mean, they technically won't be able to "See through" the wall because we are viewing the world of 2 dimension in other perspective, not technically seeing through the wall. It will be more accurate to say that they will be able to view what is over the wall from other perspective
You didn't understand 🤦. It is normal to see them in an other perspective... We see them in the 3d that they don't have access... They don't have this perspective....
well its more like theyre perspective of another variable. We see in a small localized instances of time, well in theory the fourth dimensional creature could see a regular 3 dimensional object throughout its entire lifetime. atleast thats my favorite and most logical reasoning for our theory of the fourth dimension.
@@Bingo264 What I meant twas that if 4d creatures existed, they will be able to view our 3d world from another perspective which is impossible for us to even imagine.
Our sense of self and identity exist within our brains, so technically when we think “I’m me”, it’s actually our brains saying that we are who we are Simply put, we, or more specifically the idea of ourselves are the brain Our brains are us and we are our brains
3D being: Minding their own business 4D being: /gamemode spectator *Is now able to see what the 3D being is doing, even through walls, and can even see under their clothing AND inside their body*
There is no "through the wall" in 2D, you're seeing every dimension of the wall by looking at it. There can be nothing in front or behind the wall and it naturally has no thickness.
True. It's kinda confusing since the pov of his 2d drawing makes it so easy to assume a 3d world from that 2d perspective. But basically the visible part of the wall we see on the paper is the whole of the wall. It that 2d wall had atoms, we'd basically be able to see all the atoms just from that perspective in our dimension. So basically a 4d person can see all the atoms of a 3d person simultaneously, as if were spread out flat on a piece of paper. Which is hella trippy.
I disagree, u should be able to see through and object, or more like everything and object is in terms of three dimension. If a 3d being like us sees everything that fits in two dimension, then a 4d being should be able to see everything that exists in 3d including if theres anything in front or behind it (really every molecule if you're eyesight was good enough ig). So I think you should be able to look "through" objects. Like, if you looks at a car in 4d, you wiuld be able to not just see the outside but the inner mechanisms and all that.
basically 4d is like being the cameraman in 3d rendering software , you can see through walls and all that stuff but also it must be much more complicated
Because it doesn’t exist. 2D and 1D worlds don’t exist either. You people are delusional. It’s all an optical illusion made by 3D objects so that you perceive it as 2D but in reality it’s just lights on a freaking screen. I’m not sure how people buy into this bs.
I don think so, cause from which ever angle you look at it you don't see 3d but 2d, seeing objects in their entire 3d form is 4d but it's not comprehensable by humans 😕
Had a thought. Do we "see" the second dimension, but live and perceive it as the 3rd? Just as a 4th dimensional being would be able to live in the 4th dimension but only see the third? Like- what I'm seeing right now could be projected onto a map, exactly how a picture works. When we close one eye, we lose most of our depth perception, because our brain uses the differences in each eye to PERCEIVE depth. Auxillary information in stuff like shadows and obstruction of vision via another obstacle are supplementary factors when determining depth. When an object is in front of us, it's obviously easy to determine it's location. But things like the moon, or planes in the sky are different. Distant objects naturally get harder to place spacially because there is less and less difference in what both of our eyes see. So do we really see in 3D? Just a rambling from a bypasser. Let me know if I'm wrong.
@@jharmley6882 no the picture made it look that way though. A 1d person sees the world in zero dimensions. A 2d person sees the world in 1dimension. A 3d person sees the world in 2dimensions. So a 4d person sees the world in 3dimensions. Like they would comprehend all 3d space around them entirely.
I finally thought of a name You just explained exactly why this train of logic makes zero sense. The dynamic between the first and second dimension do not share the same characteristics as the dynamic between the second and third, as demonstrated in the video. Although the video makes an accurate claim about the interaction between dimensions 2&3, this cannot be applied in a simple mathematical sequence. A 4th dimensional creature would likely be capable of understanding space in a very unique way compared to how we experience it.
@@Jplays-Games ohh he’s talking about the checkmark being drawn the opposite way of how he does it. So I still don’t see his point but I see what he meant
You could literally expand that 2D example into 3D and it still functions the same. It tells us only about direction, not dimension. If I stand at the end of a wall I can see both sides of it. The analogy should be that in 3D that wall might merely be a pillar, and Josh and Molly would see eachother just fine since the pillar was to their side.
I was thinking the exact same thing. If I hadn't heard of a similar explanation of this 2d, 3d, and 4d comparison I would have thought of this as bullsh*t.
Isn't that the point of the video? Using an example that we can comprehend and expanding it past our theoretical limit of comprehension in a manner we could understand?
@@amyschildgamerlive4519 No, he is saying that the explanation of the 2D vs 3D was poorly executed since they would both function the same. I.e. a 2D person would not be able to see beyond the wall and neither would a 3D person. With a wall as the object it's about which direction you are looking from rather than dimension.
You don’t see both sides of it. Even if you’re on the side, you won’t be able to see the side on the other end. You also don’t see the insides of the wall.

You are a 4 dimensional creature since time is also considered a dimension, they should've reworded it to either say 5 dimensional or 4 _spatial_ dimensional
@@studynow6615 Yeah, it's physically impossible for us to comprehend a 4D space. Something we can comprehend, however, is time. Another funny thing to think about is that we live in a 4D world (3D + time), are constantly comprehending 3D space, but see things in 2D. Weird, huh?
That's actually a great way to explain 4D. Tweak the hack a bit so it shows a bit of an outline of the walls and that might be the closest we can get to an understandable example.
@@StudleyDuderight i mean if u want to understand 4d, there are numerous mathematical models that helps. the simplified concept is that... a bunch of points makes a line... 1D a bunch of lines makes a square... 2D a bunch of squares would make a box or cube... 3D so, a bunch of cubes would make a shape called as tesseract... 4D !!! 😲😲😲
there is also a concept where a 0d object like a point would not have an ability to move. the 1d object would only move in one direction to and fro... like only left and right OR only up and down. the 2d objects get a ability to move in all directions and turn or rotate... on a plane (paper). the 3d object would get an ability to "jump over" obstacles... which any other 2d or 1d objects cant. now... imagine a 4d object's ability.... if i were to lock u into a solid steel cube, with no entry doors, the kind 4d creature would still be able to rescue you out of it, without breaking the cube. just like we would pick molly and place beside the dude, without breaking the middle wall. 😲😲😲
A 4th dimensional being could also reach into your stomach and remove the contents without going through your skin, the same as you could take the mouth off a stick figure's face without breaking the circle of its head. It could also flip you across the 4th dimension the same as you could lift and flip a non symmetrical 2 dimensional shape on a paper. If you had only your left ear pierced before the flip then after you would feel exactly the same but everyone else would be confused about your right ear now being pierced and how your dominant hand seems to have changed.
@@wizbromanakajeffthejoykill7635 It would need some kind of limiting factor to make it intersting. Like a being with only partial access the 4th dimension. Someone smart enough could write some really creative containment procedures. Without any added limitations for the story a 4 dimensional being would basically be a god. Imagine something that has an entire extra dimension through wich the neurons in its brain can be connected, and that could stride between 3d universes like ours the same way that we can walk to the left.
Imagine a sport where the players have to avoid/or play with 4th dimensional objects, and the complete lack of compensation on any part. "Messi ran into the wrong parts of the field and turned back into a four year old, and the goal keeper got hurt too, he's only a skeleton and ash now! Can you believe it folks!? Maybe some of the home team will survive this match after all!"
But guys I have a question if I were in a soccer match and there is a huge wall that separates the two teams from each other and I'm sitting on the chare from up and I can see that two teams are I considered and 3 dimensional person and they are two dimensional ??
