Annals of the New York Academy of Sciences, 2001 Abstract: The basic workings of inflationary models are summarized, along with the arguments that strongly suggest that our universe is the product of inflation. It is argued that essentially all inflationary models lead to (future‐)eternal inflation, which implies that an infinite number of pocket universes are produced.

Stochastic eternal inflation is in the swampland
Journal of High Energy Physics, 2019 We demonstrate that there is no controlled description of stochastic eternal inflation consistent with the refined swampland de Sitter conjecture.

Is non-minimal inflation eternal? [PDF]
Nuclear Physics B, 2010 The possibility that the non-minimal coupling inflation could be eternal is investigated. We calculate the quantum fluctuation of the inflaton in a Hubble time and find that it has the same value as in the minimal case in the slow-roll limit. Armed with this result, we have studied some concrete non-minimal inflationary models including the chaotic ...

Can backreaction prevent eternal inflation? [PDF]
Physical Review D, 2015 We study the effects which the back-reaction of long wavelength fluctuations exert on stochastic inflation. In the cases of power-law and Starobinsky inflation these effects are too weak to terminate the stochastic growth of the inflaton field. However, in the case of the cyclic Ekpyrotic scenario, the back-reaction effects prevent the unlimited growth

Local Observation in Eternal Inflation
Physical Review Letters, 2011 We consider landscape models that admit several regions where the conditions for eternal inflation hold. It is shown that one can use the no-boundary wave function to calculate small departures from homogeneity within our past light cone despite the possibility of much larger fluctuations on super horizon scales.

First Observational Tests of Eternal Inflation [PDF]
Physical Review Letters, 2011 Companion to arXiv:1012.3667. 5 pages, 2 figures. v3: replaced with version accepted by PRL. Significant extensions to the Bayesian pipeline to do the full-sky non-Gaussian source detection problem (previously restricted to patches). Note that this has changed the normalization of evidence values reported previously, as full-sky priors are now employed,

Entropic force scenarios and eternal inflation [PDF]
Physical Review D, 2012 We examine various entropic inflation scenarios, under the light of eternality. After describing the inflation realization and the normal condition for inflation to last at the background level, we investigate the conditions for eternal inflation with the effect of thermal fluctuations produced from standard radiation and from the holographic screen ...
