This is probably obvious to most Vorts, but I would like to expound a little on the meaning of dimension
We all grew up with the term dimension referring to the physical, as in two dimensions, or three dimensions, and we can easily relate to the three spatial dimensions. But to the physicist/mathematician, dimension is a more general term referring to the number of degrees of freedom or variables in a mathematical equation. Prior to Relativity, physicists could describe a point/object in the universe using the 3 physical or spatial dimensions. Relativity added time as a 4th fundamental variable to the 3 spatial ones but time itself is not a spatial dimension; it is just another variable in the equations for Relativity The articles referenced by Jones argue for a different meaning for time, and the first article is about a group of researchers whose treatment of time simplifies at least some of the math in physical theories, and avoids the paradoxes arising from the current definition of time. The articles were a good read, and I hope they continue their work formulating a new theoretical framework with a different definition for time, since it is long overdue and frankly, for many including myself, 3D+T was the proverbial bean under the mattress of fundamental physics.

From: Roarty, Francis Ø Time is a real dimension mediated by virtual particles. In the end this argument dissolves into semantics. At least in the absence of data, it does. For instance the argument that time-is-not-the-4th-dimension essentially can be parsed to prove that the fourth dimension is time.
