Eternal Inflation in the Light of Quantum Cosmology
Speaker(s): James Hartle
Abstract: If the universe is a quantum mechanical system it has a quantum state. This state supplies a probabilistic measure for alternative histories of the universe. During eternal inflation these histories typically develop large inhomogeneities that lead to a mosaic structure on superhorizon scales consi... read more

Quantum Mechanics with Extended Probabilities
Speaker(s): James Hartle
Abstract: We present a new formulation of quantum mechanics for closed systems like the universe using an extension of familiar probability theory that incorporates negative probabilities. Probabilities must be positive for alternative histories that are the basis of settleable bets. However, quantum mechanic... read more

Quasiclassical Realms and Copenhagen Quantum Theory in a Quantum Universe
Speaker(s): James Hartle
Abstract: One of the most remarkable features of our quantum universe is the wide range of time, place, scale, and epoch on which the deterministic laws of classical physics apply to an excellent approximation. This talk reviews the origin of such a quasiclassical realm in a universe governed fundamentally by... read more
