What Exactly is a Tesseract? (Hint: Not a Superhero Stone)

I have a simple question - in which direction do you run the fourth coordinate axis in a 4-dimensional world? Because we know exactly 3 directions in a 3 dimensional world.
So in which (and why) does the 4th axis in the 4 dimensional go?
What makes you think that it is in this one and not in another?
Thank you for your attention.

Mathematics is a tool, it is the language with which we describe reality. It is not reality.
In mathematics as in prose we can create entities and interactions that cannot exist in reality. That's why you can describe 11-dimensional mathematical entities. They, like Shrek, do not exist.
Sorry, such a climate!

A point can be seen as a straight line if it moves in the speed of light. (Or faster than light.)

Dear.. I have a clue.
We as human can see and perceive the 3D world clearly through our phone's 2D screen. However, we can't visualize the 4D simulation through it. I think the best way to explain 4D concept is through using 3D screen like Hologram for example..

And then you have the uneducated that believe the 4th dimension is time. Haha.

I’m only here because my imagination is like “tv” I can see vividly what ever I want so when I heard this concept it’s 2am and I’m like why not lol. Randomly needed to download a calculator app on iPad and do some math and now yup I can imagine in 4d. Lol it’s like “Mirror world” in my head now.

We are 4D change my mind🙂

Excellent video. Neil Armstrong was such a good astronaut in part because he was an engineer, so in a way he was a designer and understood the construction of equipment, rockets, whatever. Same thing is true with understanding the Tesseract, If you draw one yourself, or even better, have access to virtual reality and build one in there, we’ll have a more fundamental understanding of what the tesseract is. Thanks for the vid. 😅. In a lot of ways, time and essentially space-time share a lot in common with the Tesseract - multiples of 3 space overlapped. One of my biggest wishes in life is for the theory of gravity to get solved during my lifetime. If the fourth spatial dimension is real, the theory of gravity will give us the answer. 🎉

tht kick was personal💀💀☠☠

nop... this still doesn´t convince me... cannot go further than 3d in this reality... doesnt matter how many lines reaches one point.. try not to think it using a more complex shape... it will always be xyz.. dots lines planes and solid object

that's what i needed to know it's each face of the cube a new cube

We are probably a simulation with limitations ready to become ai, but wait.. we've already discovered ai and a lot of scientific things we can't fully grasp 🤦

So yes. It is possible. But at the same time it is an infinite smear to us. Which brings out the building blocks of time.

Math doesn’t always check out this simply is not physible

Is the 4th diemention time?

came here because of interstellar

Now I actually see the tesseract. Thanks for an amazing video.

Is it really 8 cubes though, or an infinity of cubes?

One could argue that a line contains an infinity of dots.
A square contains an infinity of lines in both direction.
A cube contains an infinity of squares in all 3 directions.

so wouldn't a 4D cube contain an infinity of cubes in all 4 directions?

Alright, I built my own tesseract out of cubes, and now can see up to six dimensions 😳

I see like, 24 squares and not all the squares have 4 intersections 🥴

tank you, however i have some doubt, such as:
the idea of the tesseract and all other 4 dimension shapes are useless, i mean if the four dimension is time, u are telling me that out there there are things that can change time? seems so stupid.
3 is the perfect number, 4 is too much. For me is just matematics speculation on the 3 dimension.
just my humble opinion...

No audio... ?

A tesseract is the 4th dimension.

NOT JUST MARVEL. WRINKLE IN TIME TOO!

Only dimension that we need is heaven

Wait, what? You say "replace each face with a cube" and then you show a cube with each face beveled in. This doesn't mean each face is a cube (which has 6 sides), it means each face now has 5 sides. 4 edge faces and one in the center. Where's the 6th side? You also say each corner has 4 lines, but the corners connected to the center face only has 3 lines. I'm really confused.

I think 4th dimension is pretty fucked up

Whats the said math that checks out? I'm somewhat of a scientist myself

This is by far the weirdest Cyanide & Happyness episode I have ever seen and it's really saying something.

So you take a 3d cube's 1 side & turn it into a another cube with 6 more sides. .. that sounds retarded. ... ... ...... This is not sufficient. .. you're supposed to 'double your points' every time you go up 1 dimension.
Do better.

are black holes 5d or 6 d

This is one of 3 videos I've seen that actually explains it good enough so that we can understand, it genuinely feels like my brain is trying to block out any attempt at understanding the Tesseract

Why does paper only have 2 directions and not infinite diagonal directions.

W, X, Y and Z, is 4D

The cartesian method be it 2 or 3 axis was there to help visualize coordinates of a point in time or space from the first place , tessaract is a mumbojumbo BS

I'm so glad I looked this video up I've never really understood the real concept of dimensions but I really understand it all now wow....I love to learn about new things....

but in 2D you can also go diagonal so shouldn't it be 3d ??

5d is internal, 4d is time, KRS One can explain what 5d is

Most helpful visualisation that I wanted, thank you Sir.

From my previous understanding, this video seems to be close with no cigar. Replace the word "tesseract" with "hypercube" every time it is said in this video. A four dimensional object, with all internal angles being equivalent to 90 degrees is a hypercube. The three dimensional object that you get by unfolding the hypercube is a tesseract. A tesseract is 100% fathomable by human beings.

A 4-dimensional sphere would be cool

I have never done it nor heard, seen, or read about it (by it I meant my coming idea, lol) before, but it seems to me that the best idea to demonstrate ( or at least explain) a tesseract is to create a cube either from glass or thin metal without covering the six sides, hang the cube suspended using invisible fishing strings, and shed light from eight sources: four exactly on the upper four corners and four exactly on the middle of the upper sides of the cube. sit a table about the depth of the cube under it and put a clean and clear white sheet on the table and underneath the cube. The reflection of the cube on the surface of the table will be the closest to a tesseract shape.

The idea of replacing each square face of a cube, with a cube, is the single most helpful idea I've encountered for visualizing and conceptualizing in 4D. I can't recall ever hearing it before either, despite it being so intuitive. Interesting, and many thanks!! You've literally changed the way I perceive 3d representations of 4d things! 😁👍

I came across your channel from the Fibonacci sequence and I love your videos. They are very easy to understand and I really appreciate it.
Im just 13 and I am interested in these different types of concepts.

Me sees half of the title: What a stupid question that is. Everyone knows that
Also me after seeing the full title: 😶

4D cube

👍👍
