: We have use multi-dimensional theories such as general relativity, superstrings theory etc.. we have only considered one dimension of time and the rest are all spacial dimensions. The current one dimensional time have only forword or backward but if there's two time dim. it becomes a plane! interesting to know what would it be like to live in such universe.

Wayne: Time is nothing more than a yardstick. It provides us with a means of describing motion. Since motion is linear, time is linear. Without matter, and motion combined, there is nothing to change in the way of "relationships" among "physical" bodies. Time has one, and only one function. That is to describe some increment of change. Since increments, by definition, are unchanging (an inch is always an inch & a second is always a second) time is fixed. In other words it won't warp or bend. If it warps it ain't time. Kip Thorne's book uses the phrase: "Einstein's outrageous legacy" Outrageaus is a good choice of words. Einstein was a brilliant thinker, but buying into Minkowski's "curving" (he didn't like the word warp) time because that was the only way he could make relativity make sense. Was not his most brilliant thought.
