Holographic multiverse and the measure problem
Speaker(s): Alexander Vilenkin
Abstract: We explore the duality, conjectured in earlier work, between the wave function of the multiverse and a 3D Euclidean field theory on the future boundary of spacetime. We propose that a measure for the multiverse, which is needed in order to extract quantitative probabilistic predictions, can be deriv... read more

Meet a Scientist - Alexander Vilenkin
Speaker(s): Alexander Vilenkin
Abstract: Theoretical models for cosmology – from standard to exotic (e.g. cosmic strings and monopoles). “Quantum creation” of multiple universes out of nothing; eternal inflation and the anthropic selection of a world that would ultimately become hospitable to life.

Measures of the multiverse
Speaker(s): Alexander Vilenkin
Abstract: Inflation is generically a never ending process, with new 'pocket universes' constantly being formed. All possible events will happen an infinite number of times in such an eternally inflating universe. Unless we learn how to compare these infinities, we will not be able to make any predictions at a... read more
