The Unique Nature of Cosmology

George Ellis

Mathematics Dept. University of Cape Town

Ellis takes a generally sceptical view of cosmology‘s attempts to explain the origins of the universe, and in particular emphasises the difficulties of substantiating the currently fashionable inflation theory. He argues that attempts at explaining the origin of the universe depend on assuming that at least some of the laws that govern spacetime in our universe, also comprised a pre-existing set of physical laws before the Big Bang. They assume the properties of quantum field theory and of fields and laws that seemed to have existed independently of the universe or anything to act on. The manner and location of their existence is unclear to Ellis.
