Multiverse: One Universe or Many?

The inflationary theory of cosmology, an enduring theory about our universe and how it was formed, explains that just after the Big Bang, the universe went through a period of rapid expansion. This theory has been critical to understanding what’s going on in the cosmos today. But now, this long-held notion—which seems to suggest as-yet-unproven and perhaps unprovable features such as the multiverse—is under increasing attack. Through informed debate among architects of the inflationary theory and its prime competitors, this program explored our best attempts to understand where we came from.

It's 8 o'clock. Do you know where your Universe is? Start by imagining a tropical lagoon To the fish that live here this watery world is all their reefs This lagoon is their entire Universe they have no idea there's anything beyond. Well, they are fish… and that theirs is actually just one of a huge number of boddies of water on Earth surface – some like theirs and some very different. So now that you are fish what if you include that this world of ours is just a tiny lagoon in something much bigger? Could your fish brain handle that? unique we think that once an only Universe 14 billion years ago
