"The Fate of the Universe: From Beginning to End"
The question of whether the end of our Universe will mirror its beginning through a new Big Bang triggered by dark energy remains unanswered. Cosmic inflation, which set up the hot Big Bang, ended in a second-order phase transition, while vacuum decay scenarios rely on first-order phase transitions, suggesting fundamental differences. Although dark energy and inflation may be related, any discussion of a future vacuum decay scenario remains speculative, with no evidence to validate it. The possibility of such a scenario occurring is open, but firmly in the realm of pure speculation at this point.
