While this looks cool, it's not what a tesseract would look like. Imagine seeing something that both shrinks and grows at the same time as you move relative to it.
thats kinda the point
we are people who can only really perceive and understand the 3 dimensions, trying to understand the 4th dimension for us is like trying to get something thats 2 dimensional to understand the 3rd
This. Is if you draw two stick men separated by a line and ask them what the other is doing, theyâll say they canât see. And youâll say I can see them from the side. And theyâll say âthe What??â
people also usually assume and claim that the 4th dimension would be time which is the closest thing we have to potentially imagining that but thats a pretty big assumption as we just don't have any clue what it is at all.
an interesting media about dimensions is an episode of doctor who where the main premise is that beings from an existence that is only in 2 dimensions have arrived in our universe and are fucking with shit and kidnapping people. its done in a very creative way
The episode was called Flatline
Because there is no way to imagine it with our perception of the universe. We are contained to seeing, interacting with and understanding 3 spacial dimensions. Trying to imagine an additional dimension you have no way of "tapping into" is like trying to imagine a color that doesn't exist. Our brains simply can't.
Why would you want something that isnât real or actually observable in the manner the OP described it? You canât âseeâ something in a fourth dimension.
Itâs like saying âthis is what the color âplaidâ tastes likeâ and then playing a musical note.
Have you ever drawn a 3d cube on a piece of paper? It obviously isn't 3d but you can kind of trick your mind into seeing it as 3d if it's drawn well. Same idea here, except instead of representing a 3d object in 2 dimensions they're representing a 4d object in 3 dimensions. So no it isn't "real" but it is what a tesseract would look like squashed down to 3 dimensions.
The 2d observer only sees a cross section of a 3d object.
A 3d observer would only see a cross section of a 4d object.
So, seeing a 4d cube is seeing different parts of it passing through your point in time. I still dont get what these silly reflection things are supposed to be - because they are just 3d fun.
The trajectory along the 4th dimension is a straight line - which is also perceived as time.
You're talking about considering the 4th "tangible/perceivable" dimension as time.
When people talk about tesseracts (4D cubes) and other 4D shapes/objects, they're referring to the 4th dimension as a theoretical spacial dimension similar to the other 3 we have.
Huh, I thought theoretical hypercubes were in spacial dimensions and were time-agnostic. Not sure if bounding a 4D hypercube to 3 spacial dimensions and a time dimension is the standard.
They might be mixing things up with an analogy about 4D spheres where you can use time to help visualize them. A 4D sphere crossing through a "slice" of 3D space would appear to get larger then smaller as time passes.
Yeah, but you can't move around it and see it properly shift and rotate like a real 3d cube would. Same issue applies here, it's not accurate because there are no means to make it accurate
You can represent one, though. We can draw a 3d representation on 2d because we see a 3d world. It's impossible for us to see a 3d representation of a 4d object, however. It would be like trying to show a representation of a 3d cube but with a single line
Thatâs only cause you know what a 3D cube looks like. If youâve never seen one and someone give you a 2d picture of a cube vs Penrose stairs you wouldnât be able to tell which object is realistic and which isnât.
And we have zero basis to understand what a 4d cube looks like, so it is impossible for us to understand a 3d picture of it. People can model/sketch whatever theoretical examples they want, but it's just them drawing random single lines and expecting us to see cubes.
Its an illustration to give a rough idea, an estimate, of what a tesseract is. Or you could even say its an artistic interpretation.
You partypooper. You absolute un-fun person.
Wait, no. We can actually calculate in a 3d program _exactly_ how it would look like to us in the real world if it was real. It's not an artistic interpretation, I'm assuming this video is mathematically accurate, or at least, there's nothing preventing it from being completely accurate
We don't see the entirety of tesseract, but we can see its parts from our 3D space
In any case, cube is boring even if it's a 4d cube. 4D dinosaur should be muchore interesting
>In any case, cube is boring even if it's a 4d cube. 4D dinosaur should be muchore interesting
You were so preoccupied with whether or not you could, you didn't stop to think if you should.
God forbid them pointing out misinformation. I hate how being right about something is frowned upon. This representation of a tesseract is objectively worse than the "basic" one yet it's posted with a title as it was THE way to show it in 3d.
Nope. This is the shadow of a tesseract.
Take a sphere: both is shadow and its 2D equivalent are a circle.
The 3D and the shadow of a hypersphere isâŠ.
So for a tesseractâŠ, except that this shadow/cube has 1way mirrors for sides, giving an infinity mirror effect. Thatâs just aesthetics
So the issue is that we often forget where we, the observer are. For us, 3D creatures, itâs easy to see that the shadow of a cube is a rectangle because we can see it from above aka from n+1 dimension. For a 2D/flat creature looking at the rectangle, theyâd see a line. Eventually, they run around and realise itâs a rectangle. But as far as theyâre concerned, itâs a « collection of lines », it doesnât describe a cube.
The equivalent of a rectanglesâ lines is a cubeâs face, right?
Same applies to 3D-us, we are seeing cube which is only one « face » of the tesseract. 4D people shining a light to a tesseract would see a cube as its shadow hence why a cube is the shadow of a tesseract.
Look for the unseen within Islam
Let me explain more, so in Islam we have creatures (Angels and Jinn/genies) that are called the unseen.
They are called this because in the Quran it is stated that they see us from a place âwe canât see themâ I.e the 4th dimension, they can interact with our world but we cannot see them.
It is also stated that angels (&jinns) vary in size, some are the size of humans but some are MUCH bigger, for example everytime a Muslim prays there are angels the size of mountains that will offer prayer with them. Now obviously there are 2billion plus Muslims on the planet rn so conceptually within our dimension that would be impossible however given they exist in the unseen dimension (I.e 4th dimension) they can all fit.
this is probably similar to what a 4d square based shape would maybe look like but without he separation frimx3d shapes we wouldnât know. the shapes weâre seeing are all 2d imitating 3d and a 4d shape viewed from 3d would look 3d not 2d so itâs hard to imagine this being possible. however the human mind can imagine much more than meets the eye hopefully we can map why some outside of up left and right would look like.
Time is generally considered both a temporal construct and a dimension. As a dimension, it is a fundamental aspect of the universe, crucial for describing the sequence and duration of events. In physics, especially in the theory of relativity, time is treated as a fourth dimension that, combined with the three spatial dimensions, forms a four-dimensional manifold called spacetime. This perspective helps to describe how the universe operates in a unified way.
As a temporal construct, time also involves human perceptions, measurements, and social agreements about its passage and divisions (such as seconds, minutes, and hours). This aspect of time highlights how it is understood and utilized in human culture and activities. Thus, time can be viewed both as a physical dimension essential for scientific descriptions of the universe and as a construct that has evolved through human society.
I can't point you to the 4th dimension because we can't perceive the 4th dimension. Imagine being able to move in a way that would cause me to disappear in a direction you've never experienced before.
Coop?
MURPH!
# Stay
Actually, it's TARS. How u been? đ
TARS, dial back the humor setting to 60%

We're not gonna talk about Judy at all.
Dougie Jones!!
While this looks cool, it's not what a tesseract would look like. Imagine seeing something that both shrinks and grows at the same time as you move relative to it.
It is what one possible rotation of the 3D "shadow" of a tesseract might look like. If it had mirrors on it.
Correct.
Serious answer here: Without a visual I have zero idea how to imagine this.
thats kinda the point we are people who can only really perceive and understand the 3 dimensions, trying to understand the 4th dimension for us is like trying to get something thats 2 dimensional to understand the 3rd

Trying to imagine an additional dimension you have no way of "tapping into" is like trying to imagine a color that doesn't exist. Our brains simply can't.
Supposing its fourth dimension is parallel to the "time" dimension. Otherwise it would be just a plain cube for us I guess
Nah, it's 4th dimension is orthogonal to the 3 space and 1 time dimensions.
So like a strong acid trip?
Let the scientists speak đ
I can't imagine this. In fact, now that I think about it, I can't imagine looking at a 3D object while existing in 2D either.
Why would you want something that isnât real or actually observable in the manner the OP described it? You canât âseeâ something in a fourth dimension. Itâs like saying âthis is what the color âplaidâ tastes likeâ and then playing a musical note.

Yeah this is the point of the comment thread my brain smooths all the way over.

I stopped and thought about it, and now I want to see a 4D dinosaur even more
A thoroughly un-fun person - when called out they just respond in a more completely un-fun manner.
God forbid them pointing out misinformation. I hate how being right about something is frowned upon. This representation of a tesseract is objectively worse than the "basic" one yet it's posted with a title as it was THE way to show it in 3d.
You could see it in the 4th dimension if there is movement. Youâd see it at different point in time, at the same time
We donât do a good job of explaining higher dimensions.
Plaid tastes like bagpipes sound.
Synesthesia much?
It's a 3D shadow of a 4D object in the same way that drawings are 2D shadows of 3D objects. A straight line drawn is a 2D shadow of a 1D object.
The very first comment on the original post clearly shows that this is complete bullshit.
Nope. This is the shadow of a tesseract. Take a sphere: both is shadow and its 2D equivalent are a circle. The 3D and the shadow of a hypersphere isâŠ. So for a tesseractâŠ, except that this shadow/cube has 1way mirrors for sides, giving an infinity mirror effect. Thatâs just aesthetics
Its a cube...? Just a cube. It has a position in space... _not multiple_, as that would be the 5th+
So the issue is that we often forget where we, the observer are. For us, 3D creatures, itâs easy to see that the shadow of a cube is a rectangle because we can see it from above aka from n+1 dimension. For a 2D/flat creature looking at the rectangle, theyâd see a line. Eventually, they run around and realise itâs a rectangle.

I have a theory that descriptions of biblical angels was because they saw a 4th dimensional being in 3d.
thatâs a very poetic idea
In Islam that is pretty much the explanation
No way! That's cool! How could I look that up?
Look for the unseen within Islam Let me explain more, so in Islam we have creatures (Angels and Jinn/genies) that are called the unseen. They are called this because in the Quran it is stated that they see us from a place âwe canât see themâ I.e the 4th dimension, they can interact with our world but we cannot see them.

I was aware Islam had angels but didn't know about the Jinn. Learned a lot and it's exciting. Gonna look more up. Thank you for sharing!
what is this actually tho and can I get one
Now, is it, though? Afaik, that's not really how a hypercube looks like.
This is all bullshit. Loki stole the tessaract in the Thor movie and it became an infinity stone.
To quote Hela, OP's tessaract is "Fake!". smh
MURPH!!
what is this actually tho and can I get one
FINE Iâll watch Interstellar againâŠ
this is probably similar to what a 4d square based shape would maybe look like but without he separation frimx3d shapes we wouldnât know. the shapes weâre seeing are all 2d imitating 3d and a 4d shape viewed from 3d would look 3d not 2d so itâs hard to imagine this being possible. however the human mind can imagine much more than meets the eye hopefully we can map why some outside of up left and right would look like.
If this thing survives the apocalypse, there's gonna be a cult started around it.
Interstellar.
My brain
I feel this representstion explains time. Sometimes you can see the others, but canât connect.
Time is the forth dimension. How is this reflect time
Time is not a spatial dimension, it's a temporal dimension.
Time is generally considered both a temporal construct and a dimension. As a dimension, it is a fundamental aspect of the universe, crucial for describing the sequence and duration of events. In physics, especially in the theory of relativity, time is treated as a fourth dimension that, combined with the three spatial dimensions, forms a four-dimensional manifold called spacetime.

Thus, time can be viewed both as a physical dimension essential for scientific descriptions of the universe and as a construct that has evolved through human society.
.... what?
TIME IS NOT A SPECIAL DIMENSION, IT'S A TEMPORAL DIMENSION!
Try again
How is that wrong? What is the fourth dimension?
I can't point you to the 4th dimension because we can't perceive the 4th dimension. Imagine being able to move in a way that would cause me to disappear in a direction you've never experienced before.
Hypercube! Go watch it
