I investigate whether eternal inflation is possible when the inflaton originally travels upslope the scalar potential and inevitably reaches a turn-around point where its classical kinetic energy momentarily vanishes. This behaviour occurs regardless of the steepness of the potential slope. Such steep eternal inflation, if achieved, would satisfy the recent swampland conjecture and allow eternal inflation in the string landscape.

  1. Eternal Inflation in Swampy Landscapes

    gr-qc 2019-08 conditional novelty 6.0 of 10

    Eternal inflation persists in landscapes where de Sitter vacua are rare or absent, via flyover transitions between isolated dS vacua or inflating bubble walls nucleated around saddle points.
