Energy
Herein I want to stress, and make the point__ Energy is not a physical entity.
Energy is only the ability or capacity to do work!
Energy is always measured by the work done.
* * * *
If work is done and energy is expended to accelerate a body against the resistance of Space... Then Space* must be working and expending energy to oppose the accelerated motion of said body.
Resistance is usually the quality of a body that is called inertia. In this case it is Space* resisting... Might it be that Space* can have inertia?
If Space* is photons that are without mass unless set into motion... it might have "effective" (next chapter for effective) inertia, meaning it is only in action when the photons are being forced to move.
This type of logic is part of why photons seem to fit for Space* filler.
[* go to the chapter for my concept of Space... being 3 D space contents... whatever it may be]

(4/20/2006) It seems pretty obvious that Energy existed three billion years ago and beyond. However as I mentioned otherwise, Work, is not a common place item of Earth way back then. So, the above definition of Energy needs modifying.
If you read what I wrote about Pressure, and Force; you will understand my usage and definition of Pressure, as the only basic force.
Thus I now define Energy as: The ability and capacity to cause the exertion of pressure by Universal entities. Again, Energy is only an ability or capacity. And, Energy is always a measure of expended pressure.
A measurement of pressure is like pounds per square inch. But, like speed, in miles per hour, it needs more to be useful. Pressure needs to be measured over some duration to give some value in Energy, for mankind to describe. The word and definition of Energy, is again something that was not required 3 million years ago___ things just happened without anyone calculating how much Energy was expended. In electrical, power is measure in watts, and over time is watt/hours for example. And I guess there could be pressure measured as pound/hour or kilo/hour. I, however, would like it to be more of a direct relation to something like light speed distance, LSD. Pressure could be measured as Energy units of Kilo/LSDs for example... This would make it more Universal.
It is difficult to get away from Time. But, this type of time, if kept in context, is just a comparison. Nothing more, quote the raven evermore... For, three billion yore, nary a person had heard of Lenore.
