The Multiverse, Science and Theology: A Critical Inquiry
Professor Mann explains multiverse theory and what implications the acceptance of multiverse theory may have for science and theology. If the multiverse is rejected as an explanation for the particularity of our universe, scientists and theologians are left to address why our particular universe exists rather than every universe.
Professor Mann works on gravitation, quantum physics, and the overlap between these two subjects. He is interested in questions that provide us with information about the foundations of physics, particularly those that could be tested by experiment. Robert has a lively and energetic research group of about 10 graduate and undergraduate students, where he addresses interesting questions in physics, such as
- How would relativity influence how a quantum computer worked?
- Could we use a quantum probe to peek inside a black hole?
- Is it possible that the Big Bang could be replaced with a black hole at the beginning of time?
- New tests of the equivalence principle are being designed and investigated. Such tests provide uswith important information about the gravitational force, and may give some clues as to the structure of quantum gravity. Specific examples include gravitational redshifts of quantum vacuum energies, non-metric effects on anomalous magnetic moments, gravitational depolarization of polarized light and neutrino flavour mixing due to gravitational effects.
- Physical properties of black holes are being studied as a means of gaining insight into quantum gravity. The formulation of the thermodynamics of gravitating systems of finite size (such as a black hole in a box) is being carried out to this end. Pair production of black holes and quantum corrections to the laws of thermodynamics are being investigated as a means of gaining a fundamental understanding of the origin of black hole entropy.
- Theories of lower dimensional gravity are being investigated. Such theories model many important conceptual elements of classical and quantum gravity in a context that is mathematically simple and elegant. Specific projects include a study of the N-body problem, gravitational collapse, dilatonic black holes, and interior structure of black holes. Lower- dimensional black holes.He has also been involved extensively over the decades of his career in science and theology dialogue and reflection.
