Many physicists believe that energy is quantitatively conserved. However, qualitatively speaking, there is a unidirectional change of this energy conventionally called entropy. In a final analysis, entropy is the change of energy from a more ordered configuration (useful) to a more chaotic (useless) configuration. Furthermore, this change of entropy is allowable only for all isolated thermodynamic systems far from equilibrium where there is no transfer of mass and energy across the system boundary enclosed by its control volume.

In light of the new conceptual definition of a time axis, each isolated system possesses its own unique time axis. This time axis keeps the system independently isolated from its neighboring mass-energy systems. The relative alignment of an individual time axis with other infinite axes determines the life-span of each individual system. Nevertheless, the effectiveness of the influence of other axes is restricted within the closest neighborhood that is in the immediate infinitesimal (catastrophic domain) region of the control volume.

When a singular time axis becomes aligned with a higher level (higher dimensional) time axis then the system reached a point of no return, from isolation, to closeness, to openness. Once it becomes an open system, all individual characteristics disappear, and the system is dead. Nevertheless, the singular time axis lives on becoming part of a bigger system by aligning with the bigger time axis. Collectively speaking, this bigger universal time axis is the set of all sets of time axes.

I beleive that the fact that entropy increses or decreases determines the direction of entropy in the time dimension. "TIME" is a dimension, and dimensions don't "move". I like to think about dimenisons as highways/motorways and the objects are the cars, bikes and trucks in the roads, moving one way or the other, faster or slower....But the roads don't move! They are the "ability to move" or "disposition to move".

GUILLE,

To the best of my knowledge, entropy always increases. Nobody has a good explanation why this is so. If it decreases then a perpetual motion machine is possible.

David gow told me that there are arguments (I don't know which) used to defend that entrpy decreses/can decrease.

That's why I said it. Anyway, my important point is that dimensions don't move, things move in dimensions.

GUILLE,

Increase of entropy need not be defended. It is experimentally verified. For example not being able to construct a perpetual motion machine.

What does the nonexistence of PMM have to do with disorder?

If PMM exists then entropy is negative that is to say it is less than zero.

[Guille]

Oh, thanks.

This is interesting: Is there any problem if entropy is negative?

No. Negative entropy also means clock running backward. Movies running backward. Anakin Skywalker starts from the darkside of the force turn into the brightside of the force and back into the womb of his mother. The universe contracting. Undoing all the mistakes we made.

NOOO!!!!!!!1111

First, anakin actually start in the dark side, chronologically in reality (for us, not for them), so the order that star wars movies would be: 3, 2, 1, 6, 5, 4. (wow! stranger than the current one).

Second, I beleive that it is mistaken that everything would be backwards. The clocks would be just going forward, in the same direction, same speed, the difference is not possible to be percieved or known, apart from one unique fact: the unvierse's size, we could see it contract.
