what is the tessaract , i.e. the fourth dimension????????

Answer 1

a theory in the book "A Wrinkle in Time"
the1st d is a line
the 2nd d is a flat figure
the 3rd is a 3d figure u can touch all around in real life
the 4th d (the tesseract) it how u can get a line in space and take the two ends, fold it over to touch the two ends together so you cut out the middle and that is a "shortcut" in space basically time travel but not back in forth in "time" but 4 d is time
confusing i know
in the book it shows a diagram and describes it a bit more nicely
just flip thru the book, its the only pictures in the book and shouldnt be hard to find

Answer 2

A cube is a three dimensional object. On a two dimensional piece of paper, draw two off set squares and connect appropriate corners to show a representation of the cube on a 2D surface. Well, a tesseract, is a representation in 3 dimensions of a 4 dimensional "hypercube". Just like the drawing on the paper (2D) is not a real cube (3D), a tesseract (3D) is not a real hypercube (4D). To try to imagine a hypercube, imagine a cube inside another cube with all the respective corners connected. Here's the problem, in a real hypercube, all the lines connecting the corners of the two cubes intersect at right angles. Have fun wrapping your brain around that.

The source has a 2D representation of one

Answer 3

A tessaract is a four-dimensional object.

The fourth dimension is created by taking an axis which is perpendicular to the each of: "length" axis, the "width" axis and the "depth" axis simultaneously.

Answer 4

A tesseract is a theoretical object of four spatial dimentions, that is analagous to a cube in 3 dimensions.

Just as you can construct a cube out of six squares, so you can (in theory) construct a tesseract out of eight cubes, as follows:

Cube 1 goes on the "bottom".

Cube 2 goes above cube 1; it is the "middle" cube.

To each of the four lateral sides of cube 2, affix cubes 3, 4, 5, and 6. Now's where it starts getting wierd, because we're dealing with four dimensions:

The "bottom" of each of these cubes (3, 4, 5, and 6) attached to the "sides" of cube 1 (the bottom cube). Got it? Yes, I know it's not really possible, but this is 4-dimensional reality we're imagining.

Cube 7 goes above cube 2 (the middle cube). We will call cube 7 the "top" cube. And, you guessed it, the lateral sides of cube 7 attach to the "top" sides of cubes 3, 4, 5, and 6.

Finally, cube 8 (drum roll, please): The bottom of cube 8 attaches to the top of cube 7 (the top cube), while the top of cube 8 attaches to the bottom of cube 1 (the bottom cube). The four lateral sides of cube 8 attach to the "outer" sides of cubes 3, 4, 5, and 6.

And there you have it! Your tesseract is complete!

Answer 5

This isnt related to your question but worth mentioning .The Tessaract is also a bad *** independent movie, that won at the Sundance film festival. If you ever get the chance, watch it.

Answer 6

A tesseract is a four dimensional cube.
