oopsss... hope I've not disclosed any secret! :-)

Ah, Ok. [And thanks also for the rectification about the decreasing entropy, which is, obviously, increasing]
Actually, I have in my mind the gas expansion, that is a classical picture used to explain entropy. That's why, maybe, I'm so fixed about volume.
The particularity of universe is that the system is not expanding IN space. It's expanding space itself! The NEW space is necessarily empty, thus, we have new order. Immediately, mass and energy will fill it, creating new disorder. In few words, all we have to do is simply invent a machine to convert the expansion of universe into heat :-)
Waiting for your (more serious than my message) essay....
bye, Marco
