Hi Eugenio:
Sounds like you actually subscribe to the oscillating universe concept .. Bang .. Crunch .. Bang .. Crunch .. etc, etc. Unfortunately, this can't easily be explained in terms of the Second Law of Thermodynamics, (temperature, pressure etc, balance out in an isolated physical system), due to the rise in entropy and ultimate heat death. Ie: there ain't no such thing, (in the real world), as a perpetual motion machine .. (for good reasons) !
The Cyclic universe theory overcomes this however, as it is based on String/M-Theory 'branes', which moderates entropy.
Cheers
