The 4th Dimension

X, Y (AND Z??)

You probably know about the x and y-axes.  The x-axis is horizontal and the y-axis is vertical. Did you know that there are also both the z and w-axes?

The z-axis involves imaginary numbers. For more information about imaginary numbers, go to https://mathblogone.blogspot.com/2021/11/imaginary-numbers.html

If the area where a function lies on the x-axis is an imaginary number, the function will raise out of the graph like it was a 3D object. Imaginary numbers on a graph are represented not by length or width, but by depth. Essentially, the z-axis makes 2D items turn into 3D items.

The image above is showing a rotating tesseract. Let me explain to you what a tesseract is. Suppose you have one dot. You have another dot that is horizontally one inch away from the other. If you connect the dots, you get a one-inch horizontal line. You have two parallel lines. Connect the edges and you have a square. A square has all the measurements for 4 sides. A cube has all squares equal, and a tesseract has all cubes equal.

The fourth dimension is known as time. In the 4th dimension, time is not forward only. If there was a human in the fourth dimension, they will be able to move forward or back in time. In the fourth dimension, time is a spatial dimension where objects will have some form of the fourth dimension.
