Imagine being able to live in 4D for a few minutes, then being cast back to the 3D world, feeling enlightened but permanently trapped.
We all exist in the fourth dimension, we are only not capable of perceiving it. If one were to be able to perceive the fourth dimension, it would be of no use, but once given the ability to freely manipulate the fourth dimension, you're stepping into psychic territory. Which really wouldn't even require the perception of the fourth dimension, merely the understanding of how it affects the third dimension that we're capable of perceiving. At least, I don't think it'd be of any use otherwise.
True. If the theory is right anyway, we're all 3D cross-sections in greater dimensional worlds. Weird to think that.
Technically we exist in all dimensions that also exist, but are bereft of the ability to perceive them, at least not as objects of their actual dimensions. For example a 4D object would appear as 3D cross sections before seemingly disappearing from existence

we'd probably either be ripped apart by supergravity, die from whatever oxygen or gravity was there, or be put back inverted with our insides outside our body because a higher dimensional being can do that, let me explain, imagine us pulling out a flatlander from their dimension and flipping them over to put them back, imagine that on a higher dimensional scale

On 0d data
On the contrary, i think it makes all the sense. There's always math in nature.
if we want to experience 4th dimension, we should do the same aligment. we should store our brain in 1D binary code then project our self on a 2D screen then showed in a 3D then we can experience 4D!
Alej Random technically, nothing is 2D or 1D on earth. Everything's got a length, width, and height.
Watching this as a 4d person must be rly funny
we are watching this in 2d, as screens are 2d
4d people wouldn’t be watching it, they’d be tasting it or some sht 😂
It's like seeing a projection of a 3d cube move on a 2d plane. We're basically seeing what a 4d creature would see but we don't intrinsically perceive depth in the 4th euclidean dimension, which is why the figure seems distorted to us but to a 4d creature that has access to a dimension perpendicular to ours, they can just move into that perpendicular direction and see that the "shorter" sides are in fact not short and are of equal length as all the other sides, while we would have to move the 4 dimensional object for it to project into the 3rd dimension because we're only allowed to move in 3 dimensions.
@@spectralanalysis u smart bruh i think understanding the 9 dimensions in space and 2 dimmensions in time are important to proving and understanding string theory and why gravity exsists at a sub atamoic level but its funny because these dimensions only exsist when you get smaller than sub atomic so seeing people make this stuff is cool but slighty funny i think

Thankyou for the visualisation of 4D as time. Its something I've been thinking about on a personal philosophical level. It brings me a lot of comfort thinking about myself as part of this huge 4D object. Knowing that as time passes; the things and people I remember and love and miss continue to exist as part of a 4D space. Like - they're not gone, gone, I'm just past the point of perceiving where we overlapped.
That's an interesting way of thinking! Loved it!

Like, we watch videos all the time. We see the videos as 3D, even though our screens are invariably 2D.

@@lkmlmlioj This is a year old comment, but, the 2d people do not see the depth in the video. They see it as we see it, up down left right, no forward or back. which, if you put yourself and imagine that, THEN you can understand how 4d is coming into 3d from ALL directions not just the flat surface, and the 4d cube is different possibilities for the cube, in regards to time. And as it looks is a lot of jumbled information that takes a lot of processing bc we usually only process one instance of this spacetime, and therefore make it a reality because it is dependent on our observation. We are more than we think, we exist in the fourth dimension but cannot see ALL of it. Because this experience is 3 dimensional, like our bodies.

"It's just so beautiful"
Trying to imagine what a 4th dimensional being would see is making my head hurt
If you try to imagine it first you must get 3d vision.You can't.
You might need a third eye for that... since we need two to see three-dimensionally .
or just 4 dimensional eyes that can see things in 3d, which can see all sides of a 3d object
A 3rd eye wont do anything new other then add a third reference point for triangulation which only gives you depth that we already have.
Sort of true.
A 3rd eye if it's like a human eye would accomplish nothing.
But a 3rd 'eye' if these are things that capture an entire 'volume' may be necessary to see 4d space in the same sense that we see 3d space with two eyes.
In other words, it would let you see the 4d equivalent of 'depth'.
However, all three 'eyes' in this case would have to be quite different structurally to how our eyes work.
What makes me sad is that the fact, scientist like Carl Sagan can't see this beauty anymore, despite they only left us several years too soon 😓😓😓
Again, this is NOT the 4d object, is the 3d shadow of the 4d object...
this is as much a 4D object as objects in "normal" games are 3D. The fact that you display it on a 2D surface doesn't make it any less three dimensional.
What you are neglecting is that the only reason a 2d object can be observed as 3d on a 2d medium is because we know what are the implications of observing in 3d and what images and objects do on this medium. We dont have the information to make ourselves model that behavior onto 3d objects that represent 4d objects. In 2d we know where the shadows and the distance in relation to point of view relate to our 3d world so that we can model that. Again, however, we dont know how light, for example, behaves on a 4d object in 4d space. so we can't model that. Not as of now at least. Im dubious of humans ever being able to really understand 4d, all we can see are the shadows and shadows do not interact the same way as real objects.
If only we had four eyes so we could perceive two 3D images at once...
Then we could understand four dimensional objects
Fasteriod, AKA Rowanze We only percive 2D
Your previous statement is definitely correct, each eye can only see in 2d.
2d + 2d = 3d
3d + 3d = 4d?
Now throw the 4d hypercube and leave a trail!
Cambesa going to 5d!!
SKO Not how it works but nice thinking.
I mean, if you count time as a dimension on its own, that is technically how it works, seeing as how the two other apps counted time as a dimension.
time is a dimension and I've been able to just imagine this trail that anything can leave without much reference. rotating 4D cube is a bit though to grasp however, I do believe VR can make it more intuitive.
LukeDude759 But it wouldn't be 5D that's why I said that's not how it works. Did you even read my comment?
This is great. I wonder if someone can make a vr of 4d room (hyperroom i guess). With full of things like hypertable, hypersofa, hypertv etc etc. And we take a vr tour of that room through all 4 axis.
On shrooms tho 🖤
Maybe mixing the two softwares of the trail and the 4D space
Sounds interesting and cool but impossible.
something that is similar to this is the game miegakure, this video here th-cam.com/video/vZp0ETdD37E/w-d-xo.html (by the creator of the game i believe) explains how 4d objects that have known objects, such as crystals, as their 3d shadows are built (though the shadows of course aren't always completely the object but partially the object but you get the gist)
I wonder, could we place a ball in a sub cube of the hypercube, and then rotate the hypercube through 4d space much like you would rotate a cube on the 3rd axis to reorient the painted side of a cube, if we placed a 3d ball in one of the 3d sub cube shadows of the hypercube, and all sides of the hypercube were solid in 3d space terms, would the 3d ball be crushed as the sub cube shadow warped out of our plane kf perception and existance, or would it, much like a painted side of a die, seemingly warp through space as it moved into an axis that we are unable to perceive, and then reappear in a different part of 3d space as the cube reorients in 4d space? If it is the latter, technically we woulld have invented pocket dimensions by our terms, or a bag of holding for instance. As the cubbe moves out of 3d space and into 4d space, i imagone the cube seemingly blinks out of existance for us, but my other idea, of harnessing this, would essentislly be akin to a glove to some deevice, that much like if a 2 dimensional creature pushed into space itself in it's context, would reach into 3d space, could we do the same with 4d space, and essentially create warping technology of sorts, or other aplications that would almost appear like magic or super powers
Understanding the fourth dimension would be a lot easier if people would drop the "Time is the fourth dimension" thing
Justamach yes..it's a common misconception to think that SpaceTime is just added to our 3D Dimensions or directions in other words x not just a line that you can draw on a mathematical chart or graph when plotting spatial Dimensions like height width and depth.. SpaceTime is definitely not to be confused with these mathematcal 4D dimensional ideas or constructs-- if people would just Google this for 10 minutes they would find lots of things written online from scientists who have covered the differences.
+rob M.
"not just a line that you can draw on a mathematical chart or graph when plotting spatial Dimensions like height width and depth.."
I beg to differ.
2d is infinite stacks of 1D lines, 3D is infinite stacks of 2D planes, 4D is infinite stacks of 3D spaces. We travel through the fourth dimension, and experience it as the 3rd dimension. In a "2d world", you would travel through the 3rd dimension and experience it as the 2nd dimension.
Name how do you stack 3d objects outside of 3d space? I can't fathom there being any room left!
People who do not know what they are talking about insist that time is the fourth dimension. It is all completely arbitrary and the assignment of dimensions is dependent on what you are talking about.
While it is true that time is not the 4th spatial dimension.
However if you are graphing acceleration then the two dimension are velocity and time, with velocity itself being displacement and time.
Now if your displacement is being plotted in 3 spatial dimensions then time is the 4th dimension.
The 2nd and per se and 3rd examples shown in the video have time as a 4th dimension.
Now I believe that in rocket science they often work in 4D, 3D varying over time, and that it is much rarer for people to work in 4 spatial dimensions, so for now time is the more common 4th dimension.
But yes if you are talking about 5D or even 11D then time is not one of the dimensions

Yeah, in VR it's a 3d shadow of a 4d object, rather than a 2d shadow of a 3d shadow of a 4d object. :)

I remember the joy of being able to understand four dimensions a little more, and the frustration of knowing that I can never fully grasp the concept. I had just come back from watching A Wrinkle In Time in the movie theater (which was quite disappointing, I read the book first) and we were eating at Cheesecake Factory while having a good discussion about four dimensions. It’s just so hard to grasp and to think about. I think that’s what makes it interesting. I heard a good line from someone I can’t remember. They said “If we can conceive it, it isn’t new. It’s just a mashup of several other things.” The way we view a tesseract, or a hypercube, or whatever you want to call it, is as a mashup of several cubes. But when we look at a drawing of a box, it’s not a mashup of several squares. It’s a cube. I think if we try and look at the shape as the shape it is, we could get a better understanding. But that’s probably impossible. Humans can not think of what we haven’t seen.

I've often thought about how interesting it would be to make a 4D rendering engine that outputs 3D information. Just like 3D render engines use a mesh of points defined by 3 numbers (x,y,z) and outputs a 2D grid of pixels based on the location and rotation of a camera in 3D space, what if a 4D rendering engine could take a bunch of geometry defined by 4 numbers (x,y,z,t) and output a 3D grid of voxels based on a camera in 4D space? You could take a snapshot, and then look at it in VR (because you'd lose a lot of data if you projected it a second time onto a regular 2D display). I would imagine you'd get some interesting results.
I also thought same thing but now I think about it, the 3D in VR is also projection onto 2D plane(screen) but a bit more interactive one which makes it possible to change the information on 2D screen in real-time to create illusion of 3D. So I think we can't even create a projection of 4D in 3D unless we have a real 3D "screen".
PS, *I think* we can't imagine true 4D untill we step into it.. if it exists anyway, so this 4D concept is false *imo* ;)
PS, PS, cool application btw :D
It's too bad we can't manipulate three dimensional objects in real-time yet
Google 4d toys
it has 3d to 2d and 4d to 3d
+Zulubo Productions ...
any engine rendering 3D movie sequences at once is a 4D rendering engine. Every rendered point is a (static) 4D point with the coordinates (x ,y ,z, t). It's static in a sense, that the sequence itself - as a whole - never changes. In fact, it renders a 4D image - the movie sequence itself. Then it projects it into 3D - a sequence of 2D images...
The time component isn't a mathematical trick. It's real - and corresponds to the frame number. But, the most interesting part: given the physics of this rendering engine, one could rotate the 4D image before projection not only to view the scene from any other 'ordinary' angle (ignoring the t-coordinate) - you could rotate the whole 4D image by any combination of its 4 coordinates. And watch the (stunning) results...
I believe the 4th dimension is a representation of time as the past, present, and future simultaneously forming into shapes, and that our plane is not a 3d plane, but a nexus of all planes but our senses can only perceive very little. Yet our minds are the key in breaking those barriers like how we can remember the past, understand the present, and imagine the future. cough* cough*... God this weed is so good 10/10.
Lmao...we must be smoking the same bc ive always thought about time in a very similar manner lol
what we were seeing was the "shadow" of a hypercube into the 3rd dimension. exactly how a cube has a shadow projected into a 2d surface. if you were IN the 4th dimension playing around with a hypercube, it would look much much different.
Right! all of the angles and sides would be of equal length; something us measly 3-dimensional beings cannot comprehend fully
Except a 3d shadow can't be cast into a 2d space, at least not in any meaningful way.
The 3d shadow would be on the "floor" of the 2d world, except there is no floor, the dimension of height doesn't exist, and the 2 dimensional creatures only see a 1d line of what's infront of them.
However 2d creature could gain some sort of understanding of the 3rd dimension by studying the cross sections of 3d objects as they pass through the 2d plane.
To 2d being, a sphere passing vertically through their plane would look like a line (if they have 2d depth perception and can identify shapes by the their shading they'll probably recognize it as a circle) that starts off infinitesimally small then grows then shrinks again and disappears.
I think pretty much the only real way to try to intuitively understand 4d shapes is to think about their 3 dimensional cross sections as they move through 3d space.
Thatlas Caulwire i unders5and, but i still cannot think of a 4d
What if we're the shadow of 4d dimension in 3d world that pushed down from 4D dimension until it ends
Amazing description of a Hypercube. You even related it to your earlier drawings of a 3d cube on paper (@ 6:23).

@@shweyee763 what are you trying to say?
Tip of the hat to you sir.. out of all the scientists and so called smarties that I've tried to understand 4 dimensions from.. you have come the closest to giving me a truly understandable vision.
A cool thing to think about is a 2d creature and how it sees the world around them, they wouldn't see in 2d, only in 1d, they don't have the freedom of jumping out into the 3rd dimension and looking down onto and even inside of objects in their dimension. Us, 3d creatutes, see in 2d, for example, if time stopped flowing and I could no longer move around objects and was left with what was in front of me it would be like a flat painting, a 2d image. Surely this means that 4d creatures see in 3d. If time stopped flowing in the 4th dimension those beings while sat still unable to fully explore their 4d world would be left with, not a flat image, but a room. Also, you know how while looking at a square on a 2d plane you see it in it's entirety while someone in the 2nd dimension would only see the outter edges of the shape? Does this mean 4d beings would be able to see a 3d object as a whole, all faces as well as the inside and outside, without having to rotate the object or move around it?
TheNBKiller fuckin yes
just yes
love this train of thought, and im going on it right now
TheNBKiller starting to make me think we are the 4th dimensional beings.......
a 1d being sees only a dot. no matter what is before it, a dot is the only possibilty
a 2d being sees a line. no matter what is before it, a line in varying lengths is the only possibilty
but do 3d beings see only shapes, any number of shapes, but only shapes
this is the tricky part, are we 3d, seeing shapes, but percieving their 3rd dimension
or are we 4 dimensional actually bearing witness to 3 dimensional objects but incapable of witnessing ourselves(much like a square percieves itself as a line)
what if somehow someway, the 4th dimension is simply perception
what if the 5th is emotion, and so on so forth (if this concept holds true I can see time being the 4th, or 5th along with perception whereas I typically disapprove of the time being a dimension concept)
I usually prefer to keep talks about 4d in solid form but in reality the concept of 4d objects makes no logical sense to us. like trying to tell the square to go left or right......square is gonna look at you and go.....we are both lines bro....all we do is long or short(point being square struggles to even understand up and down despite having that axis)
i guess what im getting at is while I do believe the jump from 1d-2d and 2d-3d creates exponential growth, my question is, did it create so much growth that we are that far above squares thinking and we can ask all of these questions, or are we another level above 3d and that explains our vastly increased ability to ponder these questions
woah dude
The only reason we perceive three dimensions is because we have two 2D shapes to work with. That's why closing one eye eliminates depth perception. Now if you had two 3D OBJECTS to mesh together in the brain, then you'd be looking at the fourth dimension.
Theoretically this means if you had four eyes... you would be capable of seeing the fourth dimension.
2D x 2 = 3D, 3D x 2 =4D, so 2D x 4 = 4D
TheNBKiller brother your comment made me understand much more of this
A being of any dimension can only truly perceive it's own world in a dimension that is one less of it's own. For example, us 3d beings see 2d flat objects but our brains have learnt to use 2 eyes to interpret the 2d images from 2 perspectives as a 3d object. Close one eye and the world is flat. By closing one eye, the only reason we know whether an object is coming toward or moving away from us is because the size of the object changes and our brains have learnt that generally objects (or images) getting bigger means it's getting closer and vice versa.
We cannot perceive any dimension other than 2d. A line always has a tiny bit of breadth when we draw it. So it's 2d.
The case is even worse for a point dimension as our representations all have length and breadth and don't even get me started on the 4th dimension.
Taking this analogy, it would be impossible for a 4d being to conceptualize a 1d shape and would have a false 2d representation as everything would be 3d for it.
And for a 2d being, it would have a false zero D concept(point) and it would be impossible for it to perceive "-1d".
All this is of course taking into account that no dimensional being can perceive reality as a being of 1 dimension higher than itself.
In short, we see 2d shapes.
2d beings see lines.
1d beings see points.
4d beings see 3d shapes.
5d beings see 4d shapes. Etc etc...
you know any beings of other dimensions?
People always forget that we have another piece of information for depth: focus
An item further away will be out of focus when you're looking at a closer item.
@@joeywargo3650 You are correct when speaking of seeing with only one eye. My right eye has been very weak from birth. When driving a car, I have to estimate objects based upon what is kinda, sorta, a 2 dimensional pallet. When a basketball is tossed toward me, since there is no background by which to judge distance, all I see is a circle getting larger and larger. No one ever chose me to be on their team! LOL
You can still focus and unfocus objects with one eye
A 3 dimensional point is an electron
Ok... maybe dumb question? Just trying to wrap my mind around this. How does the concept of an angle and degrees work in the 4th dimension? As I understand it, you are not changing the hypercube in any way-you're only rotating it, correct? However, in the 3D space, the degrees of the hypercube's angles APPEAR to change (though they are presumed to not actually change). You demonstrated this with the 2D model-the cube is not changed, it simply rotates, which makes the angles look either obtuse or acute... right?
You may have said this already, and I'm about to do a Google search, but here's my question in a nutshell: Are the angles of a hypercube all 90 degrees?
Post-Google: It seems like a hypercube may or may not have all 90 degree angles-that would be a tesseract, right?
Mind-status: Blown.
Yes, all angles of a hyper cube are 90°, but the same way a square behaves in perspective, they can appear to have more or less than 90° angles

Tip for the static when screen recording, Use noise suppression! I was having really bad static in my recordings until I boosted the noise suppression. You can do this through the control panel or in your recording program(or both if you wanna swing both ways😉). Hope this helps!
Ok hear me up, 1D is length, 2D height, 3D is depth. But any object has those 3 things AND 1 thing,*light* . Yes, all objects are 4D because all items have energy and energy is light

When you fear death, remember that you are merely ascending to a higher dimension. Like a dot, a line, a square, a cube and a hypercube...what you were isn't lost. It just becomes...more.
And so, after death, you can't become anything else than a hyperhuman
What the shit
How do you know that though
Ashes to ashes, dust to dust, you ain’t coming back. You dead.

After watching this I feel like I can finally get a bit if a grasp on 4 dimensional space. Thanks. Nobody else has been able to explain it quite this well.
8:40 nice breakdown. the hypercube is a cube in time.
The 2 opposing cubes that are not connected shown here are symbolic, portraying 2 end states apparently in opposition but which are just extreme polarities of movement.
That's why the shape looks like this in 2d space. A moving figure needed to be portrayed so the 2 end states are shown,
Like a cube being 2 perpendicularly connected squares, so too is a hypercube 2 perpendicularly connected cubes.
It only looks like this on paper, in actuality every 4d object resembling the shape of a donut since the movement is from inside out for each living body.
Not like turning your insides out, but from within each cell, like how a plant grows and such
first off, great video! question: now that we know what a cube looks like in 4D, what do other shapes look like? how about a tetrahedron, a sphere...a cat? id love to see more!
Another thing to remember, for those who are starting to get how hypercubes work, is that in 4-dimensional space, every single cube would look like perfect cubes, just like every single square on a cube looks like a perfect square in 3-dimensional space. There's no possible way we could see what this would look like on earth, though, and I'm frustrated by that.
This is the best I've ever been able to understand the 4th dimension- thank you!
You’re playing with a 4D object but you’re only able to see its shadow.
What would make this helpful for me is to have something in the cube and see how moving the hypercube changes it.😅
I'm still not fully understanding 4d, But, this helps out a ton and I feel I understood a bit more. like I'm closer to understanding it. so thank you. :)

8:41 when you highlighted the cubes opposites blew my mind

Same as mine tho
I have made the conclusion that all dimensions are "time". A dot is a dimensionless reference point. It is located "nowhere", however, it has an underlying "dimension" called "time", or "duration", meaning that for the dot to exist in a determined amount of time, it has to go through a "counter" which will determine its duration. Let's say a dot will last 100 units of time. Then it disappears. It's position was zero. TIME= W.
Now, let's add the dot, left and right. Then we have X, as dimension 1. One dimension is comprised of X*W. A Line is nothing but an extrusion of a point during a determined amount of time towards a determined direction, repeating itself indefinitely to maintain the illusion of being a consistent line. Let's say it does this 100 units of time.
Now, bear with me for a second--what if we extrude a LINE (a sucession of points) upwards or downwards? Let's extrude this line upwards 100 times. What do we have now? A single dot, extruded 100 times to the right creating a line, this process repeats upwards, the "line" extruded 100 times above, then back at point zero, repeating the cycle indefinitely, forming the illusion through persistence of vision, of a perfect square. Total amount of units of time used for one cycle for a square= 10,000. 2D=X(100)*Y(100)*W(1)
Now, let's take a square, and extrude it 100 times away from us, adding the dimension of depth, forming in fact, a perfect cube. This cycle takes up one million units of time, since X(100)*Y(100)*Z(100)*W(1). We have a cube (3D=X*Y*Z) that existed for one cycle (*W)
For the fourth dimension, the cube is extruded for, let's say, 100 cycles towards the right. Leaving a trail, that in the fourth dimension is visible as a "stick", but in our three dimensional space, we perceive as movement, since we are "wired" to understand our world in a linear way, and we're not "equipped" with the ability to go back or forth in time. That process took 100 million units of time. From extruding a dot 100 spaces right, extruding the resulting line 100 spaces upwards, extruding the resulting square 100 spaces away from us, and then extruding the resulting cube 100 spaces elsewhere, taking a full cycle for each space the cube is extruded, forming a trail of cubes, 4D=X(100)*Y(100)*Z(100)*W(100)*P(1).
Think of it as how an old CRT screen forms a 2D image (look for a video in TH-cam, CRT TV in slow motion), fooling us into believing there is a picture, it has X, Y, and the cycles repeated for each full frame, with changes between a frame and the next, and this gives us a 2D image with the illusion of movement. This happens at 60 Hz (meaning, 60 times per second, each frame repeated for 2 cycles/Hz, giving us a framerate of almost 30Fps), now, if we are FOOLED by a TV, which by splitting a motion picture at 60Hz, gives us the illusion of a 2D image in movement, aren't we fooled enough by the illusion of volumetric space, solid matter, linear time, all changes occurring at a PLANCK-SCALE of time, which is a second divided by 10⁴³?
If we take each "unit of time" previously mentioned as a Planck time, and make a cube of 100*100*100*100, we would have a cube moving around during 100 cycles, consuming a total of 100 million Planck times in a second, comprised of 10⁴³ (ten tredecillions) planck times, it is an almost insignificant fraction, even lesser than ONE grain of sand out of all the sand of Earth (calculated at 5,6*10¹⁸ grains of sand on Earth), that would put you in perspective, but taking all of this into account, I subjectively conclude "space" does not exist, it's all a dot changing positions in a cycle in an X coordinate, times the number of cycles repeated in an Y coordinate, times the number of cycles repeated in a Z coordinate, time the number of cycles this is repeated by changing positions of the whole object in a W coordinate. Repeat this several times a second for every object or being in our observable field of vision, and it will never reach or surpass the amount of units of Planck time present in a second.
Taking this into account, the only way I could imagine a 4D object, is a motion blur of an object moving too fast for our senses to keep track of it in a solid state.

In regards to the chair throwing, after it has been thrown would you say... to view that chair in 4 dimensions would be to view its past? The trail of the chair connects to itself and makes a "4th dimension", but the only way to see this objects "4th dimension" is by viewing its past motion. Sidenote, does this mean time is the 4th dimension? or perhaps motion or light are the 4th dimension? Just throwing out ideas.
My question now: If we can at least think of the 4th dimension, can objects in the 2nd dimension still move upwards? And sure I know that's not how it works but we just heard about 4th dimension so why not?🤔
They can if they are a cross section of 3D objects
Extremely Nice, You have got a new subscriber !!! For the first time I was able to visualise the uses of VR in education (to say) (other than in phobia treatments !!)
Something I just gained from watching this video: a cube is created by taking a square and "pulling" another square out of it. So if you can imagine, you have two overlapping squares, you take one of them and pull it towards you, and imagine the four lines connecting the two squares together stretching out as you do. With the hypercube, it just looks like an ordinary 3D cube, until you "pull" the other cube out of it, which was overlapping with the first cube the whole time and you just didn't know it.

This video auto-played while minimized, and I thought it was a mark rober video. Dude sounds like him a lot.
The important fact to consider is that in the 4D world all the lines in your cube are the same length and all the angles are 90 degrees. It shows as deformed in our 3D world, but understand.....same length lines and 90 angles. Each cube in the construct also has the same 4D version of what we call volume. A “solid” 4D cube looks like a regular 3D cube on the outside, but inside, all those other cubes, angles and lines still exist just as much as the outside appearance does. The wire frame build helps to show that. You can’t visualise it, but you can understand it.
This makes me feel funny in my tummy.

Can't we display a 4D image on a 3D screen and then project that 3D image onto our 2D displays for our 3D beings to look at and get the sense of depth?
Edit: I'm not the only one
What helps me feel a bit at ease about not knowing what the 4th dimension looks like is that the way you percieve the space of your dimension is just the previous dimension, for example: a 1st dimensional being would see a single space like an infinitley small dot (the dimension zero) since the being would only know left and right, a 2nd dimensional being is only able to see an infinitley thin line (the 1st dimension) seing as they gain vertical sight and movement but no width, the same applies for us as we only see 2D images of our surroundings, but not the things behind, below us or any other sides. This leads me to belive that 4D beings would percieve their dimension as a 3D projection without limits of direction or perspective.
In one dimension the metric to measure is "length". With infinite lengths lying next to each other in one direction it becomes an "area" with 2 dimensions. 3 dimensions of volume, means that an "area" is extended into another direction, like pushing a square upwards, off of a plane. So infinite 2d objects "areas" make a simple 3d object with a "volume". By that logic, 4 dimensions means infinite "volumes" connected, meaning that even the most basic 4 dimensional object would be larger than the conceivable 3d universe.
Kathan Shah volumes are also made of infinitely many areas. That doesn't make your water bottle a universe.
It doesn't have to be infinite, just apparently continuous. It's perfectly fine, for example, to have a finite number of discrete areas immediately adjacent to each other such that the space between them can't be differentiated from the collection of them, resulting in the perception that they constitute a volume of finite size. A 4d object would not necessarily be larger than the 3d universe in any 3d slice of it, as demonstrated quite clearly by our ability to project 4d objects into 3 dimensions.
Doesn't "infinitely many" suggest that we cannot seperate all those "areas" to such a degree that we cannot seperate it any further? Our universe has a measurably small "smallest unit of measurement" os it doesn't seem to be infinitely divisible (real numbers are I guess, but that's math which can even transcend our dimensions).
Just like you can draw a pretty 3d looking cube on a 2d surface, you can make a 4d looking HyperCube in a 3d space
That was the entire purpose of this video fuckhead, a pretty 3d looking Hypercube huh ?
Zayy Rugga no need for name calling. He was probably just repeating what he watched in the video

A 4th deminsional being would be like a time patrol agent. Hear me out. The last few minutes of this video shows how the 4th dimension is a plain where time (unlike in the 3rd dimension) is bi-directional. As 3D beings we are able to control length, width, and height. Time controls us (in an illusionary type of way) in a sense that we cannot control nor navigate time contrary to the presets of our dimension.
4th dimensional beings are not bound to a uní-directional experience. They are able to see ones life as a stream. The first moment and the last moment are connected.
IMAGINE
a 4th dimension being as able to see a map of someone's life. That map shows our lives just as the last 4 minutes of this video shows the chair as a chain each moment is connected and persuaded by the moment before it. But every moment is visible as one solid link.
Imagine every person you've ever come in contact with. Imagine how their chains crossed your chains. Imagine how their chains impacted your chains which caused your chain to imagine other chains.
These webs of chains is the 4th dimension.
When people take DMT trips, they realize that we are all connected. They constantly say how our energies are one in the same as everything around us. That's why. Our chains are all connected.
I also think time is the major controller of the 4th dimension. But I think time is 3D, in that rather than it being linear, it is a complex web, where every event is connected to each other, so thst any event can be reached at any “time”
I believe your comprehension of time as a fourth dimension is mistaken. You’re referring to spatial dimension as time, which it is not. Spatial dimension and temporal dimension are different. Here, he is referring to spatial dimension. If time were the fourth dimension that would be like saying the rest of the dimensions don’t have time without the fourth dimension.
In theory there are 11 dimensions according to string theory, which assumes a single dimension (string) winding and wrapping with other strings forms each subsequent dimension there after. Kind of like how amounts of hydrogen (a single proton and neutron) form all elements after (helium is essentially two hydrogens, lithium is three hydrogens, etc.). The first single dimension multiplied, forms all dimensions.
Fourth dimension you refer to is not spatial but temporal. Which would make time infinite as you mention. To see time physical, would be like seeing every frame of a video simultaneously while comprehending each frame, which a human brain cannot do. No matter what hallucinogens are inhibiting neurotransmitters. The best example I’ve seen of this is the movie “Intersteller” it was very accurate, as physics based parts were developed by well know physicists. As well as reviewed by other physicists. I highly recommend it.
Your reference to drugs ability to inhibit receptors in the brain, is not at all a connection to any other dimension or energy, as the brain is incapable of experiencing anything out of the third dimension we exist in. The brain is simply hallucinating based of of each individuals prior experiences and references from memory (video games, movies, something someone said days or weeks earlier). If any case, energy from other dimension may have an influence on another dimension as a constant, should an object interact, as seen with the apple here from Carl Sagan, who explains it so anyone can pretty much have a general understanding of it: th-cam.com/video/N0WjV6MmCyM/w-d-xo.html
Also, reference to spatial and temporal dimension, for thos who are interested: th-cam.com/video/eGguwYPC32I/w-d-xo.html

The problem is that our eyes in the 3rd dimension sees a projection of 3D in 2D. If we could see in 3 dimensions, we could see inside things that we normally wouldn’t be able to. People in the 4th dimension see in 3 dimensions and people in the 2nd dimension see in 1 dimension. With this VR app, you are projecting a 4D object and seeing a 2D projection. Very cool
Now spin that figure 8 in the fourth dimension...
*darude sandstorm intensifies*
So since the 4th dimension encompasses time, then wouldnt experience be considered a 4d slice, as each moment in 3d time. From the cosmos down to the quanta.
Revision: more aptly the 4th dimension would be more akin to space experiencing itself through the lens of time.
Am I the only one who noticed that the entire into was ADR? Like I may be wrong but the audio seemed like it was recorded after the video, which is really impressive if it's true because you got the speech pattern and foley down perfectly.
Is it safe to say, all dimensions above the 3rd is optical illusions? And/or self-reflective of their shapes? (I suppose 3d to a 2d world is also optical illusion)
Time is not optical as such. 3d life is 4d life because time is the 4th dimension of space-time. So I don’t get all this talk about this mysterious 4th dimension
Then I have a question: If cubes work With more connections, how do balls Work in the 4th Dimension or are balls the only shape, that exist in every Dimension?

@@webaccount167 thank you
@@paulk.4202 A ball sort of thing is symmetric all the way around, so no matter the rotations in 4-d, the 4-sphere will look the same.
i think you should have clarified the fact that what we are looking at is not literally a 4th dimensional shape, but rather a projection of a 4th dimensional shape in the 3rd dimension, it's basically like what the real object's shadow would look like if that object was transparent, also it's important to note that when you manipulate that object in vr, the real 4th dimensional tesseract is just rotating, it's not actually being morphed like how it would appear to us in the 3rd dimension.
I find it interesting how the instances are doubled.

Thanks for your explanations. I saw something like this before
and thought it was cool seeing the cubes move like that. I remember
putting a sphere inside of a sphere in blender and thought "a world within a world".
To relate our bodies to the double cube is the inner world projecting to the outter. In this video, notice how big the 4d projection is compared to the 3d body. That she traveled through time space to get to the mortal world. th-cam.com/video/DTV5GK4DeHM/w-d-xo.html
Or notice how in this: m.th-cam.com/video/JhD9bzzkjlM/w-d-xo.html
the inner world(being) is interconnected to the outter projected(being). Notice how the inner being blocked the attacks shot at the outter projection. Finally, when he sank back in the water it looks like it disappeared yet the dimensions are still there.
Thank you. Your explanation was a significant puzzle piece in my understanding of 4D.
What would the human body look like in the fourth dimension
Seethrough, like an energy body.
Rybellion Williams I think you could see trought the body. Because you as a being of 3d dimension can see "trought" a 2d object.
Victor Sousa How can you see through a 2D object exactly? You can't see through a piece of paper. The examples in the videos are wire frames to help understand the objects better, which is why you see through them. A solid object won't be so easy to understand, but a solid object in 2D remains solid in 3D; why wouldn't that be the case for 4D?
nockieboy Well, actually, I mean you could see inside the 3d object from another perspective, you also would be able to see all the sides of the 3d object at the same time. Imagine you in a 2d universe, you are a 3d being, 2d being house's are just empty squares. And 2d being of course can't see inside his house from outside,(notice that , 2d being vision is just a line) but you as a 3d being can see inside the square, and all the sides of the square, but from another perspective.
nockieboy A piece of paper is still a 3D object. It has a thickness. Just because it's incredibly thin and flat, doesn't make it a 2D object. You could probably see through a 2D object because it has 0 thickness. At that point, it probably doesn't even exist.
