It implies a much bigger universe than the observable one: the inflation never ends in the universe, and the central role is given to the concept of false vacuum -- a metastable state characterized by higher energy than the rest, negative pressure and strong repulsive gravitational field -- which, as a probabilistic process, drives the accelerated cosmic expansion, for the universe undergoes a phase transition from false | + | The inflation theory, as the exponential expansion of space, with a less accelerated rate after the period of inflation, tries to give some answers to these puzzles since the early 1980s.
