Quantum Field Theory Constrains Traversable Wormhole Geometries
L. H. Ford, Thomas A. Roman
Recently a bound on negative energy densities in four-dimensional Minkowski spacetime was derived for a minimally coupled, quantized, massless, scalar field in an arbitrary quantum…
Uncertainties of predictions in models of eternal inflation
Serge Winitzki, Alexander Vilenkin
In a previous paper \cite{MakingPredictions}, a method of comparing the volumes of thermalized regions in eternally inflating universe was introduced. In this paper, we investigate…
Predictions from Quantum Cosmology
Alexander Vilenkin
After reviewing the general ideas of quantum cosmology (Wheeler-DeWitt equation, boundary conditions, interpretation of ), I discuss how these ideas can be tested observationall…
Refutation of C. W. Misner's claims in his article "Yilmaz Cancels Newton''
C. O. Alley, P. K. Aschan, H. Yilmaz
It is shown that an article by C. W. Misner contains serious errors. In particular, the claim that the Yilmaz theory of gravitation cancels the Newtonian gravitational interaction…
Averaged Energy Conditions and Evaporating Black Holes
L. H. Ford, Thomas A. Roman
In this paper the averaged weak (AWEC) and averaged null (ANEC) energy conditions, together with uncertainty principle-type restrictions on negative energy (``quantum inequalities'…
Making Predictions in Eternally Inflating Universe
Alexander Vilenkin
Eternally inflating universes can contain large thermalized regions with different values of the constants of Nature and with different density fluctuation spectra. To find the pro…
