Abstract

Spatially-homogeneous and anisotropic Bianchi type-1 space time is investigated in Barber’s second self creation theory (Gen. Rel. Grav. 14, 117(1982)) and also in Rosen’s [Gen. Rel. Grav., vol.4 (1973)435] bimetric theory of gravitation, when source of the gravitation is perfect fluid. Models found in both the theories of gravitation have been compared and shown that Barber’s second self creation theory is more consistent than that of Rosen’s bimetric theory of gravitation.

Keywords
