Here's fuel for thought: as 3D beings, we can fully perceive anything and everything on a 2D plane (as demonstrated by the circle-in-the-box scenario), however due to the lack of the third dimention, a (theoretical) 2D person would find it impossible to look "up" and see us, as we simply exist above their dimension. Taking this one step further - if a 4D person was to look at a 3D plane, they too would be able to perceive everything at once - you, the house you're in, the plumbing of the house, your organs digesting your last meal... anything. And the scary part is, as we exist on a 3D plane, we would be completely unable to look "out" to see these 4D people. They could exist, and be watching you read this, right now, but you wouldn't be able to tell. ;)

@@Loo_Kah no. The 4th dimensional cube that we all call "tesseract" is the equivalent of a glass box in our dimension. It is made for us to understand how cubes work on 4 dimensions. The real terrasact is a "closed" object in our perspective, we will still be able to see all it's sides but we will need to walk around the box to see it. However, as for 4d beings, they will be able to see it's "shadow" as a 3d object, but will still be able to see all it's sides even if they looked at it in one perspective. Basically, it's similar on how "glass" cubes are made for nursery students to understand how a box works, and how the shadow of a box works, we will be able to see all sides of it as a line at an upper perspective, but 2d beings will need to walk around to see all of it's sides. I hope your mind doesn't shut off simultaneously after reading this...

[@JuneJulia]

The idea of 4th dimension beings can see inside the box is not correct. If there's actually a fourth dimension then there could be another part of the box that we didn't know which could block the view to see the sphere.

Of course not, just because you can’t observe something from one perspective doesn’t nullify it’s existence. And your example relies heavily on time TRAVEL, instead of what time is supposed to be: a measurement system. Just like length, width, and distance. Sound familiar? Let’s try something, say we have a ball and a box. You take the ball and put it in the box. Where’s the ball? In the box, of course. You watched it go in there, you remember it. You can envision it in there. Hell, here’s an extremely convenient visual for what you’re probably thinking of: 3:35 . This is a little something called object permanence, the one thing we use to identify intelligence in organisms, and surprisingly ignore it everywhere else. Honestly, I’m just tired of seeing these geometry buffs insisting that anything “4D” has to still be something you can see, taste, and put your dick in. These are just 3D constructs that can be inverted on themselves, get your head out of the tessaract.

As explained by Da Shi, a cigarette filter is a small thing, but if you were to unroll it and spread it out as a 2d object, it would fill a whole room. As dimensionality rises, physical presence would diminish. Earth, unfolded entirely into a 2d plane would be infinitely larger, but as the speed of light is a constant, on this hypothetical 2d plane, light would take longer to cross the same distance, so time would also move relatively slower due to absolute constraints.

[@andyhughes8315]

I watched a similar like 10 video years ago. I'm just now starting a undergrad math degree. Cool stuff. In mathematics, something in dim 4 depends on how the coordinate system vectors and variables are defined. A function of 2 vars is a 3D surface essentially where z = f(x,y). One application is apparent temp as a function of windspeed vs actual temperature. Then in machine learning its even more flexible, where any coordinate vectors / variables can be defined as anything. Different ML algorithms will optimize the higher dimension equations. However, in basic Physics, vectors are restricted to the 3 spatial dimensions, time, or noncontact field forces. And every law of conservation is essentially both a scalar potential function and composition of functions. So there can be different force fields embedded in 3D space. And a higher dimension function can model the system.

Imagine being on a plane (graph paper, or even just plain old line paper), and you are a line on the 2-D surface X,Y. The paper represents where (You) are and what (You) can percive. If, let's say we have a circle on the paper as well, it would look like a line, save for when it moves either farther, or closer, on the two planes of existence. If we took a shpere, a 3-D object and tried to move it on said 2-d plane, it would be confined to the rules of said dimensional plane. Since the Shere would be able to move in three different dimensions, X,Y,Z The object would appear to be 2-D to you. As the object moves side to side on the x and y scales, it would look normal. Things get weird when you start moving on an axis that doesn't exist. The shpere, while moving on the Z axis passing through the 2-D plane would appear to shrink until it looks like nothing is there, before suddenly popping back up and growing in size. This is a really compact version of things I've been thinking about and am not really sure if its correct.

Maybe you could determine there is something in the box because of experiments like banging on the box and hear that it is hollow.

so 4D is being able to see the front and back of something, like a medical scan. that kinda makes sense cause you don't see them at the same time but time isn't a spacial dimension. when you see a shape you are always seeing a max of three sides (ex. top, left, right, in isometric), but a cube has 6 sides so you need to see the other three sides to see the full shape ( += bottom, back-left, back-right). So having a fly-through/walk-around image scan is another dimension than a regular "3d" jpeg image.

[@PunamKumari-rc7md]

You got it slightly wrong... A point in time is 0D just like it is in space you can't move. linear time is 1D since you can move forward. Probability is 2D so there are multiple simple timelines parallel stacked one over the other. The question is... what is the Third dimension in time? Theory about the 2nd dimension of time : The laws of physics in the world remains same. It is the natural selection factors that differs. Let's say in a world you toss a coin. No matter how many timelines you see the outcome will be the same if the surrounding conditions are. Now let's say there is another Earth where dinosaurs aren't dead. Why? Because of the law of natural selection. There is always a tiny randomisation in every world. For example, you can have a new element in some other world. Now let's say the meteor that was supposed to hit Earth was made up of a certain element but it doesn't exist in another universe, how will there be a meteor then? Or what if the meteor was made up of some other element and it never came to Earth due to that. Therefore, we can conclude that probability can only be altered by factors such as chemical reactions and the randomness of consciousness....

[@deusexaethera]

I agree, it's hard to wrap my mind around too. We don't have the mental capacity to directly visualize 4D objects, because our capacity for visualization is learned from what we can see in the outside world. (hence why people born blind have non-visual dreams.) But the concept is similar to this: A figure-8 is the 2D facsimile of a Moebius strip, but a real 3D Moebius strip doesn't need to pass through itself to connect its two ends together like a figure-8 does, because a real 3D Moebius strip has that extra degree of freedom provided by the Z axis. Similarly a real 4D Klein bottle has an extra degree of freedom provided by the W axis, allowing the little connecting tube to wrap around its main body instead of having to pass through it.

[@GachaWolf81900]

What if 4th dimension isn’t a spatial dimension but a literal mirror dimension of our world where things are similar but different, that means stranger things is 4d and stuff, but it would make sense as a 4th spatial dimension couldn’t fit in with the other three and it’s not time because we live in a 3D world with xyz coords but we also have time so obviously that can’t be it so maybe it’s a literal dimension that’s mirrored or something of our world?

I imagine 4 or more dimensions as connecting two parts of the room that do not normally connect in 3 dimensions but can also connect in 3 dimensions. It is also like having an invisable space directly next to you that you can't see but you know is there. Almost like seeing something out of the corner of your eye but when you look at it it is gone. Also I imagine 4 or more dimensions almost like a room of mirrors where the reflected images actually connect even though an image reflected through two mirrors does not touch the image still appears in the second mirror. Now imagine that a 4th dimensional object can pass through what would seem like a solid object in 3 dimensions and be viewed as a 3 dimensional object. What would happen if you touched a 4 dimensional object passing through a 3d plane? Well I imagine it would feel like "pins and needles" since this object does not actually exist in 3 dimensions. However it would be very interesting to note how 4th dimensional objects can interact with 3 dimensional objects in unseen ways like from the invisible space that I mentioned earlier. For example if you knock an object off the table it falls to the floor. In this example if you were to knock an object through 4 dimensions it would disappear, bump your arm from an unseen direction and then land in the corner of the room. Hypothetically speaking of course 😅😅😅

But in instances when we do see them would probably be because they somehow got into our 3D world and my personal explaination based on theories of when people hear ”ghosts talk” is that sound can bounce through levels of different dimensions so it passes though our level sometimes, so we can’t see the entities talking because they exist on another level, however, we can hear the sound waves made by them because it bounces to our level

If it develops other senses to perceive various other dimensions it is capable of conceiving, and considering it, yet very limited in it's ability to express it.
