What is the fifth dimension?

Answer 1

The fifth dimension is a hypothetical construct. Let's start with the dimensions below and work our way to the fifth.

A point is a zero-dimensional object and has an indeterminate size.

A line connects two points and it has one dimension: length

A two-dimensional object has length and width.

A three-dimensional object has length, width, and depth.

The above concepts are easy enough to understand. Here is where it starts to get sticky. The fourth dimension is considered to be time. We live in a three dimensional universe, where there is length, width, and depth. However, we can only exist at one point in time at any given moment. In the three dimensional world only our present self can exist. Hypothetically, in the fourth dimension, we can exist at all points in time, so our past, present, and future selves exist simultaneously.

Thus, a four-dimensional object is a time line.

The fifth dimension contains different possible time lines depending on the choices you make or chance events. In other words, let's say you are born in New York to a middle class family, go to school, then college, study to become a doctor, become a doctor, get married, have children, and then die. That would be only one time line. In another time line, you could be born in New York to a middle class family, go to school, then college, study to become a doctor, become a doctor, but die in a car accident before you can have a wife and family. That is an entirely different time line. In yet another time line, the situation could be completely different.

I hope I explained it clearly enough for you to understand.
