Big Bang singularity in the Friedmann-Lemaitre-Robertson-Walker
spacetime    [PDF]

Ovidiu-Cristinel Stoica

We show that the Big Bang singularity of the Friedmann-Lemaitre-Robertson-Walker model does not raise major problems to General Relativity. We prove a theorem showing that the Einstein equation can be written in a non-singular form, which allows the extension of the spacetime before the Big Bang. These results follow from our research on singular semi-Riemannian geometry and singular General Relativity (arXiv:1105.0201, arXiv:1105.3404, arXiv:1111.0646) (which we applied in previous articles to the black hole singularities: arXiv:1111.4837, arXiv:1111.4332, arXiv:1111.7082, arXiv:1108.5099).
