This Universe of de Sitter was expanding in an infinite flat space (k = o) but he visualized an empty Universe (r=o). the expanding model of the Universe appeared strange to the physicists at that time, about a decade before Hubble’s discovery of receding galaxies. In de Sitter’s Universe, r = p = k= o, when Eqn. yields
R(t) = Ro exp [c2 Ù]1/2 t
Since R/R = H, the Hubble constant, the age of the de Sitter Universe can expressed by
It can be noticed that if in such an empty Universe we assume further that Ù= o, then we get a static Universe of undetermined extent. The basic weakness of de Sitter Universe is that it is empty and thus unphysics
