Singularity prevention and broken Lorentz symmetry

M Gasperini

Show affiliations


It is shown that, if the local gauge symmetry of general relativity is broken, the singularity theorems may be evaded, and in particular the cosmological singularity of the standard model may be prevented, even if the gravitational sources satisfy the strong energy condition.
