Eternal inflation, bubble collisions, and the persistence of memory

Jaume Garriga, Alan H. Guth, Alexander Vilenkin

A ``bubble universe'' nucleating in an eternally inflating false vacuum will experience, in the course of its expansion, collisions with an infinite number of other bubbles. In an…

Freak observers and the measure of the multiverse

Alexander Vilenkin

I suggest that the factor $p_{j}$ in the pocket-based measure of the multiverse, $P_{j} = p_{j} f_{j}$ , should be interpreted as accounting for equilibrium de Sitter vacuum fluctuations, whi…

Probabilities in the Arkani-Hamed-Dimopolous-Kachru landscape

Delia Schwartz-Perlov

In a previous paper we found that in the context of the string theory ``discretuum'' proposed by Bousso and Polchinski, the cosmological constant probability distribution varies wi…

A measure of the multiverse

Alexander Vilenkin

I review recent progress in defining a probability measure in the inflationary multiverse. General requirements for a satisfactory measure are formulated and recent proposals for t…

Eternal observers and bubble abundances in the landscape

Vitaly Vanchurin, Alexander Vilenkin

We study a class of ``landscape'' models in which all vacua have positive energy density, so that inflation never ends and bubbles of different vacua are endlessly ``recycled''. In…

Probabilities in the Bousso-Polchinski multiverse

Delia Schwartz-Perlov, Alexander Vilenkin

Using the recently introduced method to calculate bubble abundances in an eternally inflating spacetime, we investigate the volume distribution for the cosmological constant $Λ$ in…
