Hi Claudio, this might not be the way it happened, but the numbers are
reasonable. (grin)

The last collapsing universe bounced when it had contracted
ALMOST to a singularity, at the graviton pressure limit (which is
analogous to the neutron pressure limit of 10^15 grams/cc) and the
resulting false vacuum state contributed a cosmological constant about
10000 times larger than it can be today. The corresponding repulsive force
caused the universe to inflate exponentially, doubling its size roughly
once every 10-35 seconds. After at least 85 doublings, the temperature
dropped to very low values near absolute zero. At the low temperature the
true vacuum state had lower energy than the false vacuum state and this
supercooling of the universe therefore induced a rapid phase transition
from the false vacuum state to the true vacuum state, in which the
cosmological constant became essentially zero. This transition would have
released the energy differential which reheated the universe to high
temperatures and from this temperature bath then emerged the particles
and antiparticles, long before this universe's first second had elapsed!
Thanks to this once-in-a-universe bounce and subsequent almost
super-natural inflation, the new universe filled a volume of 3 light years
at the end of its first second! A free lunch indeed!
