Cosmology - New or classical physics
Abstract
The question of the apparent expansion of the universe is examined from the standpoint of the big bang theory, whereby the primeval matter coalesced into galaxies and continues to expand, and from the standpoint of a steady state theory, which assumes historical uniformity for each locality of an infinite universe. Phenomena such as redshift lend themselves to an acceptance of the first hypothesis, but exceptions to a uniform redshift have been noted, e.g., in the Quintet of Stephane, which may disprove the rule. According to the second, i.e., steady state hypothesis, the anomalous redshift may be an effect of the projection of galaxies at different distances in the terrestrial sky. A third possibility is also presented which combines elements of the other two theories, namely a situation whereby a new particle of matter is created for each unit of expansion. Attention is given to the universality of gravitation, noting that no matter which cosmological hypothesis may prove valid, objects must move to overcome the gravity which would draw them together.
