The eternal inflation of many different Universes

. Is the World Necessary?

"The more I examine the universe, and the details of its architecture, the more evidence I find that the Universe in some sense must have known we were coming." — Freeman Dyson


"A bottom-up approach to cosmology either requires one to postulate an initial state of the Universe that is carefully fine-tuned — as if prescribed by an outside agency — or it requires one to invoke the notion of eternal inflation, a mighty speculative notion to the generation of many different Universes, which prevents one from predicting what a typical observer would see." — Stephen Hawking
