ding,
Ding says motion has nothing to do with work and therefore the perpetual motion in the universe does not disprove his thermal equilibrium lie.

Motion IS the result of work!!!!!Motion is not the measure. Thermodynamic equilibrium occurs when a spatially uniform temperature is achieved. Thermal equilibrium only requires that temperature differences or other processes may no longer be exploited to perform work. And since we are no where near this point, the universe has not existed forever. That's why everyone who understands cosmology accepts that the universe is approximately 14 billion years old.At what temperature does all motion stop?The second law of thermodynamics states that the entropy of an isolated system never decreases. Such systems spontaneously evolve towards thermodynamic equilibrium. A thermodynamic system in its own state of internal thermodynamic equilibrium has a spatially uniform temperature. The second law of thermodynamics states that every energy transfer increases the entropy of the universe due to the loss of usable energy. During energy transfer, some amount of energy is lost in the form of unusable heat energy. Because energy is lost in an unusable form, no energy transfer is completely efficient. The more energy that is lost by a system to its surroundings, the less ordered and more random the system is. Entropy is a measure of randomness and disorder; high entropy means high disorder and low energy. Thermal equilibrium only requires that temperature differences or other processes may no longer be exploited to perform work. This is when the universe reaches maximum entropy.
The only way energy can no longer be exploited to do work is when all motion stops.
work = force x distance
