The Multiverse: Another Speculation

"The big bang model has some problems - homogeneity, flatness, and lack of magnetic monopoles.

"Cosmic Inflation occurred when the entire universe shortly after its beginning, expanded exponentially fast for a fraction of a second. One implication of this is that the universe on large scales may not be so homogenous. Inflation could have ended at different times in different places. This would mean that the universe is bigger and more complex than we realize. This concept is called ETERNAL inflation."
