Replication Regulates Volume Weighting in Quantum Cosmology
James Hartle, Thomas Hertog
Probabilities for observations in cosmology are conditioned both on the universe's quantum state and on local data specifying the observational situation. We show the quantum state…
The Classical Universes of the No-Boundary Quantum State
James B. Hartle, S. W. Hawking, Thomas Hertog
We analyze the origin of the quasiclassical realm from the no-boundary proposal for the universe's quantum state in a class of minisuperspace models. The models assume homogeneous,…
The No-Boundary Measure of the Universe
James B. Hartle, S. W. Hawking, Thomas Hertog
We consider the no-boundary proposal for homogeneous isotropic closed universes with a cosmological constant and a scalar field with a quadratic potential. In the semi-classical li…
Are We Typical?
James B. Hartle, Mark Srednicki
Bayesian probability theory is used to analyze the oft-made assumption that humans are typical observers in the universe. Some theoretical calculations make the {\it selection fall…
