abstract
I summarize the arguments that strongly suggest that our universe is the product of inflation. The mechanisms that lead to eternal inflation in both new and chaotic models are described. Although the infinity of pocket universes produced by eternal inflation are unobservable, it is argued that eternal inflation has real consequences in terms of the way that predictions are extracted from theoretical models. The ambiguities in defining probabilities in eternally inflating spacetimes are reviewed, with emphasis on the youngness paradox that results from a synchronous gauge regularization technique. Although inflation is generically eternal into the future, it is not eternal into the past: it can be proven under reasonable assumptions that the inflating region must be incomplete in past directions, so some physics other than inflation is needed to describe the past boundary of the inflating region.

In a wafer-modified Bousso-Polchinski model, 99.95% of the 532 million Calabi-Yau fourfold configurations in the Schöller-Skarke database allow vacuum energy spacings of 10^{-120} or smaller, with membrane nucleation transitions dominated by giant flux leaps under thin-wall approximations.
In canonical single-field eternal inflation, stochastic upward fluctuations do not violate the SNEC within the semiclassical slow-roll regime due to parametrically bounded drift and a strong timescale hierarchy N_SNEC ≫ N_BR.

Does Eternal Inflation Violate the Smeared Null Energy Condition?
In canonical single-field eternal inflation, stochastic upward fluctuations do not violate the SNEC within the semiclassical slow-roll regime due to parametrically bounded drift and a strong timescale hierarchy N_SNEC ≫ N_BR.
