A QuasiSteady State Cosmological Model with Creation of Matter
Abstract
A universe is envisioned in which there was a major creation episode when the mean universal density was about 10 to the 27 g/cu cm. Explicit equations are given for the creation of matter; in a cosmological approximation, these equations lead to expressions for the timedependence of the cosmological scale factor S(t), but do not entail, as big bang cosmology does, that S(t) tend to zero at some finite time t. The equations therefore possess a universality that is absent from big bang cosmology. Creation occurs when certain conservation equations involving the gradient of a scalar field C(i) are satisfied.
