Abstract: | TRAUTMAN has postulated1 that the usual space-time singularity occurring in classical cosmological models and in the gravitational collapse of massive objects could be averted if intrinsic spin effects are incorporated into general relativity by adding torsion terms to the usual Einstein field equations, that is through the Einstein-Cartan theory. Invoking a primordial magnetic field for aligning all the individual nuclear spins he shows that his universe consisting of 10/Sup80 aligned neutrons collapses to a minimum radius of the order of 1 cm with a corresponding matter density of 10/sup55 g cm/sup-3. |
