Le problème cosmologique et ses hypothèses. III. Hypothèses de la théorie de Hoyle et Narlikar.
Abstract
The author examines the underlying assumptions of the new gravitational theory of Hoyle and Narlikar (1971, 1972). The fundamental hypothesis is that the laws of physics must be invariant under a conformal transformation of the Riemannian spacetime geometry. Others are: all particles produce at each point of spacetime a scalar mass field of variable strength from point to point; the mass of a particle at any point in spacetime is proportional to the mass field at that point; the density of the fluid filling spacetime is either variable from point to point or constant; regions of the universe where the mass field maintains a constant sign are large compared to the range of presentday astronomical observations. Some consequences of these hypotheses are briefly examined on some examples of conformal transformations of the geometry of Friedmann models.
