In geometry, the tesseract, also called an 8-cell or regular octachoron or cubic prism, is the four-dimensional analog of the cube. The tesseract is to the cube as the cube is to the square. Copied from Wikipedia
the reason this boggles our minds is the same reason seeing a cube would make a character in a 2D cartoon **** himself. They live in a 2D world, 3D ***** them up, we live in a 3D world, 4D ***** us up
You're getting into an interesting topic... Its a debate between 3+1 dimensions vs quantum gravity and 11 spatial dimensions. The 3+1 is where we have our three dimensions as we know them, 11 spatial dimensions view time as motion through a 4th dimension, and all possible times a 5th etc., etc. Its confusing. Theres a really good video that describes it, i'll look for it and post it here
I have already seen the video. It gets complicated when he starts to mention the 7th dimension and up to the 10th. But the title says ''Four Dimensional "Cube"''. I just thought that OP didn't know the difference between the 3rd and the 4th dimension.
In the avengers it's a cude that inside the cude has infinite capicity as it holds the unisverse and just ocnnects at two point, which when you look at this shape you can see you can fit a cude inside a same sized cube which mean you could fit another same sized cude inside that and go on and on for infinity,
This is what I think. It does make a lot of sense.
First dimension - singular point. Allows no movement.
Second - the area between two points on a single plane. Allows forward/backwards travel.
Third - the area between 3 points with 1 on a second plane. Allows forward/backward up/down movement.
Fourth - the area between 4 points with 2 points on 2 differ planes. Allows forward/backward up/down and movement between the different planes.
It's a three dimensional representation of a four dimensional hypercube. There are more possible spatial dimensions then the three we live in, we just arbitrarily assign time to be the fourth.
Like an anonymous said a little while back, this is NOT how we would perceive a tesseract if we actually could. There are 12 dimensions of space (and mathematics proves there could be 13) and 1 of time. Since we, as humans, only live in 3 dimensions (length, width and depth) we can not perceive any of the higher dimensions. Same way we can't perceive colors outside of our visible spectrum. Those dimensions are still there and they still affect us, but we don't experience them directly, and, if not for the math, we wouldn't even know they were there.
It's actually an animated shadow of a tesseract. We have no way of creating a "real" tesseract because it would have right angles to every right angle we know. Terence McKenna explains it well in his video on "flat land".
I must say in our three dimensional world wouldn't a four dimensional "cube" look like a cube? In the book flatland when the sphere passes through the plane of flatland it simply looks like a circle that can change size. So a tesseract would appear to be a cube that change volume.
True. I'm using the language loosely and should apologize. We can't visualize 4 dimensional objects and so this is an animation of a 4 dimensional projection onto a 3 dimensional space. Similar to a sphere (3-d) projecting a circle (2-d) onto a sheet of paper.
though you have to remember that the 4th dimension is time, so would it be a true 4D cube we would see all of its states through the time of its lifecycle.
