Black Hole to Big Bang A Mathematically Consistent Chain in Eleven-Dimensional Loop Quantum Cosmology

I present a single physical scenario and the mathematical chain it sets in motion. A black hole containing the mass-energy of our observable universe is permitted by general relativity. If gravitational collapse to Planck density triggers a Loop Quantum Cosmology bounce in an eleven-dimensional setting, with the seven internal dimensions compactified on a manifold of G₂ holonomy as required by realistic M-theory phenomenology, then the resulting four-dimensional bounce produces output conditions consistent with the hot dense initial state from which observed cosmology evolves. I do not derive the dimensional reduction from eleven to four. I show that the published physics permits the chain, that the resulting four-dimensional critical density exhibits numerical consistency with the standard Loop Quantum Cosmology value at the order-of-magnitude level, and that the calculation that would render the chain rigorous is specified in a companion paper [12]. The present paper does not claim to close the chain. Its purpose is to make the case that the calculation specified in [12] is worth a specialist’s attention and to provide the cosmological context in which that calculation, if completed, would matter.
