Once Before Time A Whole Story of the Universe [Audiobook]

Instead of a Universe that emerged from a point of infinite density, we will have one that recycles, possibly through an eternal series of expansions and contractions, with no beginning and no end. Bojowald's major realization was that unlike general relativity, the physics of LQC do not break down at the big bang. The greatest mystery surrounding the origin of the Universe is what cosmologists call the big bang "singularity" - the point at the beginning of the Universe, prior to the existence of space and time, when gravity, along with the temperature and density of the universe, becomes infinite. The equations of general relativity can't cope with such infinities, and as a result big bang theory has never been able to give any explanation for the initial condition of our universe, succeeding only in describing and explaining the evolution of the Universe from that instant onward. Bojowald's theory takes us right up to the first moment of the Universe - and then back, even before the big bang itself.
