Abstract : In the steady state universe of Bondi and Gold, matter is continuously created at the rate of 10 to the -46th power gms/cc sec. Hoyle is able to come to a similar conclusion by modifying the field equations of general relativity. Both theories yield an expanding universe in which the density of matter remains constant. In the former theory matter is not conserved. More generally, in Hoyle's formulation, the stress-energy tensor is no longer divergenceless, and again energy (mass) is not conserved. These theories yield a local creation of mass which in turn raises the question of the consistency of such theories with the principle of causality. In this paper we take the point of view that the 'static' field which accompanies such a mass is initiated with the creation of that mass and propagates away from it with the speed of light. It is presumed that the mass is the source of the propagating field energy. These causality and conservation of energy (viz. the particle is born in an environment in which energy is conserved) statements give rise to a self consistent integral equation for the mass. Notwithstanding some objections the investigation is nevertheless consistent with the continuous creation hypothesis originally formulated by Bondi and Gold.
