The universe began in a Big Bang nearly fourteen billion years ago, and has been expanding ever since. But how does the universe expand and what is it expanding into? Sajan Saini explains the existing theories around the Big Bang and what, if anything, lies beyond our universe.
Eternal inflation suggests a multiverse wherein our particular universe is subject to the anthropic principle: the fundamental physical constants of our universe necessarily attained values that inevitably led to the formation galaxies, stars and planets, and life. Critics of eternal inflation argue the principle represents a non-scientific truism for a fine-tuned universe, tantamount to intelligent design; supporters argue we can still ascertain something about an ensemble of potential universes beyond our own. What do you think? Might the anthropic principle ultimately limit our ability to model the birth of our universe?
