General Relativity and Quantum Cosmology

Title:Can Quantum Cosmology Give Observational Consequences of Many-Worlds Quantum Theory?

Authors:Don N. Page (CIAR and Department of Physics, University of Alberta)
Abstract: Although many people have thought that the difference between the Copenhagen and many-worlds versions of quantum theory was merely metaphysical, quantum cosmology may allow us to make a physical test to distinguish between them empirically. The difference between the two versions shows up when the various components of the wavefunction have different numbers of observers and observations. In the Copenhagen version, a random observation is selected from the sample within the component that is selected by wavefunction collapse, but in the many-worlds version, a random observation is selected from those in all components. Because of the difference in the samples, probable observations in one version can be very improbable in the other version.
