Inflationary Multiverse: Self-Reproducing Cosmos appears as an extended branching of inflationary bubbles. Changes in color represent “mutations” in the laws of physics from parent universes. The properties of space in each bubble do not depend on the time when the bubble formed. In this sense, the universe as a whole may be stationary, even though the interior of each bubble is described by the big bang theory.
