Abstract
The effect of the torsion induced by the Dirac field on gravitational singularities is investigated. An exactly soluble example of the Dirac source is presented, which satisfies the energy condition for singularity theorems in the Einstein-Cartan theory. The self-induced Dirac torsion appears to enhance rather than avert singularity formation. The zero-mass limit and the neutrino limit of the energy condition for the Dirac sources are also discussed.
