A chaotic version of this process would result in fractal structuring and was proposed to be still continuing according to Linde.
Fischer and Schutzhold developed a simulation of this process in a Bose-Einstein condensate. This process' original formulation relied on bubble nucleation, which lead to the "graceful exit" problem; Steinhardt addressed that issue with the "slow-roll" variety of this process. A chaotic version of this process would result in fractal structuring and was proposed to be still continuing according to Linde. Proposed to solve the flatness, horizon, and monopole problems, evidence for this process includes the existence of anisotropies in the cosmic microwave background. FTP, name this process proposed by Alan Guth, in which the universe expanded very rapidly after the big bang.
