Is Time a “Physical” Dimension?
A. – No. In a description of the physical nature of matter, everything in physics can be described in a space having a width, a depth, and a height. Nothing more is necessary. Of course, such a description can be different later. A new three-dimensional description might be necessary after a given time interval. That description can also vary as a function of temperature and various other parameters. It exists no physical description in a mathematical equation being able to transform “one second” into “meters” (or vice versa) (called space-time transformation). Mathematics is a tool to predict numerical parameters. Mathematics does not give a physical description of phenomena. Mathematics is not physics. Just try to explain to a friend how to proceed to make a physical transformation of a “space” into “time” (space-time transformation). Mathematically it is easy. You simply write “Space” = “Time”. Physically, it is non-sense. It is not because you can write a mathematical formula relat
