Regulating Eternal Inflation with the UV/IR connection
Speaker(s): Benjamin Freivogel
Abstract: I will discuss a recent proposal to regulate the infinities of eternal inflation by relating a late-time cutoff in the bulk to a short-distance cutoff on the conformal boundary of the spacetime.

Eternal Inflation, Bubble Collisions, and the Disintegration of the Persistence of Memory
Speaker(s): Benjamin Freivogel
Abstract: I will compute the probability distribution for bubble collisions in an inflating false vacuum which decays by bubble nucleation. The number of collisions in our backward lightcone can be large in realistic models without tuning. In addition, we calculate the angular position and size distribution o... read more
