The dimension of space is then a dynamical real variable. The generalized Friedmann equation, derived from a Lagrangian, and the generalized equation of continuity for the matter content of the universe, give the dynamics of our model universe. This leads to an oscillatory non-singular model with two turning points for the dimension of space.4 pages, Latex file, contribution to Journees Relativistes 96General Relativity and Quantum Cosmologytext
