There is a quite common thinking error, in regards to 2d beings, people assume they view world in a top down way, like if we were to look at a paper drawing, but in reality they would only be able to see in 1d, just a line, in example you showed at 5:02, the 2d organism wouldn't know there is a blue sphere to begin with, all it would see is a green line and it would need to cut through it to see there's something inside or it would need to use sound, kind of like how we can tell something is empty inside by knocking on it and listening.

People talking about trying to render 4D always seem to forget that they need to project down to _2D_ rather than 3D. We've already lost a dimension just to display things to the screen. Even without a screen, we still only see in 2D. We _infer_ 3D based on various properties like relative sizes, shadows, occlusion, and parallax. A 2D being would be able to understand 2D only by using these same techniques.

[@yartastic]

Exactly! Think a sphere inside a closed box. Your eyes can't see the sphere because your 2D vision dosen't allow your eyes to look inside. But you still know something is in there, because you can hear and feel the sphere if you shake the box. Similarly, a person in a 2D space can only see the outside of a hollow square. They can't see the circle inside. But if they push the square around, they can hear and feel the circle. So they could also figure out something is in the box. This is of course assuming either dimensional beings didn't simply observe someone else put a sphere/circle into the box/square and already knew what was in it.

[@rga1605]

It's really amazing to think about that. I want to mention Flatland, a romance published in late 19th century. Spoilers for a book in public domain, but one of the best parts of the book is when the paralelogram protagonist (I don't remember much if it was a paralelogram or a square) is brought by a sphere to the 3rd dimension and gets euphoric, but then the sphere says "if that is so, then even the worst scoundrels of our world are gods to yours", and the novel ends with sphere wondering if there are indeed higher dimensions.

10:35 While I don't think the Heptapods can alter time, they do seem to be able to bend spacetime to travel great distances and altre/defy/manufacture gravity (which is just bent space-time), so I'd say that their ability to perceive time in a non-linear fashion has aided in their development of technology and likely made space travel a lot easier for them. Who knows, they could be way less advanced than us from an evolutionary standpoint, the Heptapod version of cavemen, with rock ships that travel just as easily through space-time as we do through 3d space. I love this concept!

[@onidaaitsubasa4177]

Umm technically it's gravity that bends time by dragging the physical subatomic or quantum parts of an atom that create it, but um ok, Einstein wasn't considering quantum science or the frequency separation of alternate timelines when he made the theory. Gravity is simply mass particle density accumulation, which basically is the greater the number of accumulated number of particles within a certain space, the higher the attraction value.

Imagine if a evil 4D creature decided to push you maybe a single meter in the 4th axis. As a 3D creature, similar to 2D creatures, you cannot understand, see or travel through a dimension above you, so by just moving 1 meter you’re in a new unescapable world that you cannot get off of without help of a hyper-being to get you back to your 4th axis coordinate. Another scary thing is: if you put a 2D creature in the 3D world, it will probably fall in a direction that it cannot see, and lay down on the floor in a way it cannot understand or get up from, so if we were dragged to the 4th dimension, we’d probably just fall over. Now for a third scary thing: 2D creatures don’t have anything stopping it’s insides from falling to the sides, because it can’t encase itself in a 3D way because it only exists in a 2D world, so a 2D creature’s insides would just slip out in a 3D world. In the same way, we don’t have 4D encasing, so our insides could just slip and hang out off of a direction we can’t see. So, we wouldn’t be able to go back, we would fall over and het stuck and our insides would be exposed from a angle we can’t see to possibly be entered by 4D hyper-insects/pests

I've spent a lot of time thinking about higher-dimensional space. This is the way I like to visualize it: imagine a hexagon that's been folded along all the points, then imagine folding two of the resulting "segments" under so that you have a 4-sided pyramid with a triangle sticking out on the inside. This is 4D as seen from a 3D perspective: the two folded sides are the 4D axis, and the pyramid (looked at from above so that it looks like a square) is the bottom face of a cube of 3D space. Imagine the "square" as a metre (or 3ft) of open space in a field of such "squares." From any of the four visible faces of the "square" you can move to the next "square" in the grid, and you can jump in the air, or dig down into the ground, where there would be another grid of squares one metre down. This is 3D space. Now, with the 4th axis, you can move off either of the two edges that are folded away under the "square," onto the folded edges of another "square" somewhere else in the grid, without crossing the intervening space in 3D, thereby travelling in the 4th Dimension. If there was a 3D building build on the grid, you'd be able to use the 4th axis to enter and exit without using the door. The only thing I have to do now, is figure out how the two folded edges connect up to each other. Or, go insane. 😆

When it comes to time, my personal opinion is that time is a construct, it exists in all the dimensions we can experience, moving in any dimension requires moving through the constructual dimension of time.

[@onidaaitsubasa4177]

I think technically it could be considered a wave created by unseen quantum oscillations that serves to separate different congruent timelines or separate universes by means of frequency shift.

[@PloverTechOfficial]

@@onidaaitsubasa4177 true, since time can be coaxed into different wavelengths by distortion of gravity and gravity is also a wave. That checks out.

[@drdca8263]

@@onidaaitsubasa4177 This... seems like nonsense to me? I mean, you are using words that people use when talking about quantum mechanics, but, it isn’t at all clear to me how what you are saying could be a working description of “what time is”. But it is possible that that’s on me and not on you.. If we have an isolated system described by a wavefunction, and we are in a context where relativistic effects are irrelevant, we can talk about that wavefunction being decomposed into a sum of energy eigenstates aka eigenfunctions, where the change in the system over time consists of the phases of these eigenfunctions changing at different rates, and where changes to observable properties of the system over time can be seen as the interference from these different components changing as the differences in phases change. For macroscopic things, I guess there’s a concept of “pointer states” which, like, is kinda related to the MWI stuff.. (I don’t understand quite what pointer states are...) For wavefunctions that are a superposition (I.e. linear combination) of other wavefunctions, the different components evolve through time independently, but, if they are related in certain ways, then this can look in some ways like a mix of two things becoming one thing or visa versa, due to uh, if you did the time evolution for one of the two parts individually, it would become something that could seem like a mix of multiple things, where the extra things from each of the two sides cancel out... Wow, that is not at all a clear idea when I try to express it with just ordinary language instead of math. What I’m saying is U((x+y)/sqrt(2)) = z U(x) = (z+w)/sqrt(2) U(y)=(z-w)/sqrt(2) so U((x+y)/sqrt(2) = (((z+w)/sqrt(2))+((z-w)/sqrt(2)))/sqrt(2) = ((z+z)/sqrt(2))/(sqrt(2)) = 2z/2 =z And in a sense I suppose this is kind of like a mixing of worlds/“timelines”, though I think “timelines” is probably best reserved for when they are like, different enough that this kind of mixing is no longer really relevant? I think this is the kind of thing the idea of “pointer states” deals with. I want to be clear that I’m not making the claim that many worlds interpretation is the right interpretation. Perhaps the Born rule is describing something objective, where there is an objective collapse where the wavefunction changes in a way where actual objective probabilities are given by the Born rule. Uh... In the case that relativistic stuff *is* relevant... well, apparently that basically only works in quantum field theory, and while I’ve read parts of a textbook, and parts of some papers, on that, I still find it pretty confusing. In at least the formulations I’ve looked at, there are like, these functions of spacetime that represent something like a field configuration, and these act as “test functions” that operators act on, and it is the *operators* that evolve over time, iirc. (I may be getting mixed up here... I mostly work with lattice systems, where things aren’t relativistic, and where there is a state functional which sends operators to numbers (their expectation value), and the state evolves over time.) Hm. What point was I trying to make? I guess my point is: in all I’ve seen in quantum mechanics, while the details of how time is handled, do vary in important ways, it is always a coordinate of some sort. Just like one would expect. Time is a coordinate. Or, is a coordinate to at least whatever degree that space is coordinates. Maybe I should say “is described by” rather than “is”.

5D warfare was a key part of the Xeelee Sequence series, where a hyper-advanced alien species discovered that hostile entities (that feed upon entropy itself) already exist at the beginning and end of the universe. Thus the only method of escape is to create a multi-galaxy spanning metaphysical wormhole structure that allows others to enter new realities.

you are mixing time dimensions with spatial dimensions, for clarity lets say we dont have 4 dimensions, but 3 spatial dimensions and 1 time dimension, in that case you need to specify, a 4th spatial dimensional being could see us from every angle at once , a 5th spatial dimensional being could see all angles of a 4th spatial dimensional object, BUT not the "world line" wich i guess you meant something like a "time line", that would take a 2th time dimensional being, and the one that can see every outcome would be a 3th time dimensional, you cant just mix spatial and time dimensions and then arbitrarily say that the 4th is a spatial dimension, and the 5th and 6th are time dimensions

I have some great ideas for games that few will understand: - A 4Dimensional game that doesn’t follow Euclid Laws (Non-Euclidean game in 4D). - Game above with 2D, 3D and 4D; amicable, neutral and hostile creatures/life forms. - A 5D game that has the previous idea combined with the thinking of time as a dimension, like the chess. - Now add the 5D amicable, neutral and hostile life forms (forms... does this concept still exist?) - A multiplayer game of the previous game. - The game above played in Virtual reality. Good luck for the players playing this game, and I sincerely wish good mental health for the person or group that will take on this ideas for a game. - Your 2D lifeform: Naos.

The 4th dimension being considered time can cause some confusion. It's not that time is 4D, we just say '4th dimension' because we're tacking it onto the existing 3 spatial dimensions. Time is 1D, a line dimension - or possibly 2D if you buy into infinitely branching timelines.

"You can only move in one direction of time." Motion is defined as the difference of space over time. When people wonder if they can move backwards in time, they are really wondering if their personal time can move opposite to the time of the universe. Personal time is by definition always moving forward, and your personal interaction with the rest of the universe is what makes backwards time travel impossible

So i have a theories, a 4d Creature can see all of your head angle at once For example: - You had a scar on your nape and the burn mark on your forehead, the 4d being can see both of it at once because it can manipualate time. - At 6:00 AM, you walking to school with your nape facing them, they saw the scar, 6:05 you turn your back to see a friend behind, they saw the burn mark on your forehead. So by scrolling the time between 6:00 AM and 6:05 AM, they can see both of it at once. Of course they just can using 3 axes to go around and see your forehead but since it's too annoying to do so, they used the fourth axis for more convenient. - They can even see the time when both of the scars are not there (for example the moment you are born) 6:25, this is a good example of time, you scroll to the time when the wall isnt built yet with the 4th axis, then move pass it using other 3, then again scroll the time back to the present and BOOM, you're inside

Just so you are aware, there is a way to have a single digestive tract that has two orifices and a direction of travel within a 2D creature. In the book Planiverse, 2D multi-cellular life is represented and the mechanisms of their life and biology are explored, and one of the things covered is digestion. A digestive tract with two orifices can be kept together in the same way that a zip with two zipper can keep two pieces of cloth together while allowing for a moving gap to transfer from one end of the zip to the other. It has a diagram showing how interlocking cells could be inflated with fluid or gas to make them bulge and be locked into a socket on the opposing side of the digestive tract, and be deflated or retracted to give passage. It is difficult to explain but if you tale a peek at the book it has some pretty interesting illustrations.

In the three body problem, it's revealed that the universe was once made up of 10 dimensions plus one time dimension, but the universe's dimensions were gradually lowered by 'vector foils', a kind of weapon which is impossible to stop, and gradually spreads across and lowers the dimensions of space by one. This caused the three dimensional universe we have today, which is gradually being lowered to two dimensions. Only fragments of the fourth dimension remain, which when exposed to can allow you to see through objects and reach through solid matter.
