From what i understood 4d is perceptiveing all directions all at the same time ,wich means you can see trough every object ,in and out ,back and front, up and down at the same time ,or something like this i gues Very interesting stuff 🙄🤔

Realize just a model and not a faithful portrayal of the second dimension, but bothered the whole time that the beings there would not be able to see each other. Perhaps they could sense one another, but that undermines the the analogy's being built up on visual representations.

The 4th dimension isn’t real, the 2nd dimension was created by humans and it doesn’t exist anywhere in our universe except for on phones and computers, the 4th dimension is made up and doesn’t exist nor can exist in our universe

So by those means a tesseract would cast a 3D Shadow a 3D object here/matter we are the shadows of a 4th dimension world. If light is constant. The scale should also be included matter here is made to be by being casted from the original 4d universe in Maybe subatomic particles hmmm. And it all existed in all dimensions at the same time. Thank you

But as a shadow can be casted from above/outside it can also be cast from within from the singularity, God the particle.

what if atoms are actually 4 dimensional and are expressing themselves 3 dimensionally, since they are mostly empty and the box example of 4th dimension Carl showed also appeared to be empty on the inside??

The 4D is like the 3D. Expect they can travel space and teleport. Jump to different reality’s of our own. While we’re stuck in ours. 5D can time travel. In 5D you can move in and out of space and time without being seen or even being known about. Eventually it’s a D where you can create universes yourselves or even be able to become particles and transform to different things. This is my theory. We can’t see outside our world but our world is probably not the real world. Just one of many.

There is no fourth dimension we've only experienced things that we understand to be 3D and how we express it. If you're looking for that fourth dimension it's another experience or understanding events that can illustrate our surroundings and form of time

WHY ELECTROMAGNETISM/ENERGY IS GRAVITY: E=mc2 is DIRECTLY AND FUNDAMENTALLY DERIVED FROM F=ma. The rotation of what is THE MOON MATCHES it's revolution. This PROVES that gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Great. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/AS what is BALANCED electromagnetic/gravitational force/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. THEREFORE, objects fall at the same rate (neglecting air resistance, of course); AS the SPEED OF LIGHT is RELATIVELY CONSTANT as well; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. F=ma AND E=mc2 PROVE that ALL of SPACE is NECESSARILY electromagnetic/gravitational IN BALANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Carefully consider what is THE SUN AND THE EARTH/GROUND. Witness what is the ORANGE SUN. Consider the BLUE SKY. Consider what is THE EYE. The stars AND PLANETS are POINTS in the night sky. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. The COMPOSITION of lunar rocks IS practically IDENTICAL to that of Earth rocks. OVERLAY what is THE EYE in BALANCED RELATION to/WITH what is THE EARTH. GREAT !!! THOUGHTS ARE INVISIBLE. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. THE EYE IS THE BODY. The viscosity of LAVA IS BETWEEN (ON BALANCE) what is water AND the EARTH/GROUND. The EARTH and the MOON may appear blue. Notice the relation of what is the eyelid. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. The curvature or shape of what is THE MOON MATCHES that of the EARTH/GROUND (given a clear horizon, of course). Time DILATION proves that ELECTROMAGNETISM/ENERGY IS GRAVITY. By Frank DiMeglio

Extra dimensions are naked empires. Expanding space is naked empire. The so-called gravity with real pushing forces. The pulling forces and curving space are a hiss. It is good to understand this first. The substance consists of expanding densities that recycle the expanding pushing force. All the expanding nuclei of atoms recycle the expanding dark pushing force which has e.g. the nature of expanding electrons and expanding photons. 1. The surface of the expanding Earth pushes us away from the center of the expanding Earth. 2. A pushing force through our body so that it originates from every expanding atomic nucleus of the Earth and thus pushes each expanding quark of our expanding body in separate expanding densities away from the center of the expanding Earth. 3. The expanding pushing force from the zillion-expanding quarks of billions of galaxies that collides with every expanding quark in our body and pushes them in separate expanding densities wherever it was going. And this pushing force is thus also pushing through the expanding Earth, experiencing a change in its density due to the interaction with the expanding matter of the Earth. 4. An expanding pushing force that originates from an expanding Earth and protrudes away from the Earth by interacting with an expanding pushing force pushing toward an expanding Earth. Here, it is good to note that, for example, the mass, state, and density of each expanding planet are different, so the expanding thrust from them affects the expanding planet differently with the expanding thrust. 5. The expanding planet thus interacts with the self-penetrating expanding thrust densities, and thus the mass, volume, and density of the planet are defining how much these planetary expanding densities exert a thrust on each separate expanding quark of our expanding body as separate objects. And that is, therefore, related to the accelerating movements in which our bodies are involved so that we cannot sense them with the help of our bodies. Probably too much for you. Accelerating movements we did not sense with the help of our expanding body. 1. Accelerating motion away from the expanding Sun. 2. Away from the center of our expanding galaxy. 3. Away from other expanding galaxies. 4. Away from an object that is really really far beyond the visible universe expanding in space. 😃

I've heard of time described as the fourth dimension but after watching this I realize that's incorrect. Time exists in ALL dimensions. The most mind-boggling thing about time is that we as humans have fashioned a construct using numbers so that we can measure it and understand it. However to the universe at large it is not a quantifiable or corporeal thing that can be seen. Our understanding of time is merely a concept in our own limited minds.

So basically I understood 2d:up down left right 3d: up,down, left, right, top, bottom 4d: up, down, left, right, top, bottom,in, out? What if us as matter start off in the first dimension Then 2d is like the blueprint for our 3d self's so then we are born which when we die we proceed into 4d, we can't be seen cause we are in and out of time and space just like the square could not see the apple, idek

A tesseract is 100% a 3D object. In no way what-so-ever, does it represent a 4D object. At all. Not even a little bit. Period. This is simply a thought experiment designed to get you thinking in an "outside the box" kind of way. (Pun not intended. I think). Can we even prove that shadows exist in the 4D? I dunno, it'd probably be easy to argue that they don't. Or at least that they don't behave like they do in the 3D. Personally, if it even exists, I think being in the 4D would make understanding why magnets do what they do as easy to understand as why a room with things that open (like a door, for example) can be entered while a room without one, cannot.
Jackass Chicken
Jackass Chicken 5 days ago
In regards to magnets and how they do what they do, I believe this is what some people call "counterspace". Simply put, I think that if we could see in the 4D, then we would literally see the what, how, and why of magnets and the objects they interact with. And the ones that they don't. For example, we may not fully grasp the how and why of gravity sending Timmy to the bottom of the well, but we sure understand that Timmy falling up and out of the same well ain't never gonna happen! And I do kinda doubt that shadows even exist in the 4D. First off, consider that shadows aren't even physical things. Therefore, it seems unlikely that they could exist in a place that is the opposite of space. I guess it'd have to be light then? In the outlined shape of itself? I dunno, too many opposites here. But I'd be interested on hearing why you think that they would exist. Or why you agree with me. Heck, argue for against any of this here and I'll be interested in hearing it. Unless you happen to be the retard who wants to talk about how his big truck can crush thru any wall, so doors aren't even needed in his 4D. In that case, I'll just take up religion again and pray for you. End note: its late and I'm babbling. This is just some of the random nonsense I think about. So, I'd like to add that its probably the 6th dimension that we're all talking about here. Not the 4th. Anyone care to guess why the 6th? And not the 4th, 5th, or even 7th? But then again, maybe not.
