compound, so it becomes effectively meaningless to describe space as anything less than infinitely dimensional. At that point, what you have is volume, with lots of different points moving about and the concept which effectively describes that is temperature. The scalar level of activity within an area. The same logic which uses the speed of light to say time is an additional dimension of space, could use a given quantity of energy to say that temperature is another parameter of volume, since changing its volume would proportionally change the temperature. Another observation about space and energy is that energy is what exists, while space is what doesn't exist. Without the energy, it would be completely empty and featureless. It would have a temperature of absolute zero and time wouldn't exist. It is necessarily infinite, because any limiting factor would be a force of some kind. So space alone would be both absolute and infinite. The parameters of relative energy, without being parameters that can be defined by any physical means. Steve, Consider that motion creates and erases the series of events called time. The physical energy doesn't go anywhere. It simply is. It is the configurations of that energy which change. They go from being in the future to being in the past. Rather than the flow of time going from past to future, it actually goes future to past. The earth isn't traveling the fourth dimension from yesterday to tomorrow. Tomorrow becomes yesterday because the earth rotates. It is
