The Tesseract and the Fourth Dimension

682 Words2 Pages

The Hypercube is a three dimensional representation of a polygon existing in the fourth dimension. For over two centuries mathematicians have been thinking about the fourth dimension. It was during this time that Möbius discovered the unique properties of a two dimensional strip when twisted into three dimensional space. Charles Hinton was a mathematician in the mid 1800s who was interested in what objects existing in the fourth dimension may look like. He wrote an article in New Era of Thought entitled 'What is the fourth dimension?' in which he theorized ways in which a four dimensional object could be visualized in three dimensions. He coined the term tesseract from the Greek word meaning four rays of light. This is proven to be difficult for people to visualize.
To understand the concept of a fourth dimension (4D), it is helpful to start with the simplest construction of space. Dimensions are designated by a "n" plus an integer, that represents the dimensional space. For example, n- 2 refers to a two dimensional space. When n equals zero, it results in a geometric point in space. A line connecting two such points, will reside in the first dimension or n- 1. This first dimensional line has length only, but no width or depth. If another line crosses perpendicular to this line the resulting plane which has length and width, but no depth is in the second dimension. If depth is added to this existing plane,it will result in a coordinate system, which has both length width and depth. In fact, any point in this system can be referenced by a corresponding (x,y,z) coordinate. This is third dimension and is
the easiest for humans to visualize because it is the world in which we live. If another dimension is added to the cube in the th...

... difficult to visualize it becomes increasingly difficult to do do with higher dimensions.
This fascinating four dimensional cube stretches the mind to look at and stretches the mind even farther to attempt to understand the cube. Marvel Studios used the tesseract in their movie The Avengers. Marvel used it as a portal to the other side of space, in our world the tesseract has applications of a wormhole. At least, that is what the math tells us. Even if a wormhole is a stretch of the imagination, Marvel could have used the tesseract correctly. The Hypercube blows the mind of everybody because for humans it is so difficult for us to grasp and make sense out of it. I know I can't visualize anything in the fourth dimension or anything in the

other dimensions beyond the fourth. The tesseract is insanely cool to study and the mathematicians who discovered it are genius.
