Holographic Multiverse
J. Garriga, A. Vilenkin
We explore the idea that the dynamics of the inflationary multiverse is encoded in its future boundary, where it is described by a lower dimensional theory which is conformally inv…
Predicting the cosmological constant with the scale-factor cutoff measure
Andrea De Simone, Alan H. Guth, Michael P. Salem +1
It is well known that anthropic selection from a landscape with a flat prior distribution of cosmological constant Lambda gives a reasonable fit to observation. However, a realisti…
Evolution of cosmic superstring networks: a numerical simulation
Jon Urrestilla, Alexander Vilenkin
We study the formation and evolution of an interconnected string network in large-scale field-theory numerical simulations, both in flat spacetime and in expanding universe. The ne…
Prediction and explanation in the multiverse
Jaume Garriga, Alexander Vilenkin
Probabilities in the multiverse can be calculated by assuming that we are typical representatives in a given reference class. But is this class well defined? What should be include…
Cosmic string formation by flux trapping
Jose J. Blanco-Pillado, Ken D. Olum, Alexander Vilenkin
We study the formation of cosmic strings by confining a stochastic magnetic field into flux tubes in a numerical simulation. We use overdamped evolution in a potential that is mini…
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…
