After reading throught many theories on time, I suddenly got a thought. We all know that you can put three dimensions on a cartesian plane using the X, Y, Z axis. How would other dimensions look like on the cartesian plane? How would time be graphed on a cartesian plane? So I was wondering, is it possible to graph time on a cartesian plane? If it is, how would it look like? This would make it easier to visualize the whole concept of time and dimensions. It is kind of mind-boggling trying to visualize the fourth dimension as well as the fifth, sixth etc...
