Great video on Loop Quantum Cosmology

YouTube user Skydivephil has produced another amazing video where they interview some of the scientists working on Loop Quantum Gravity, and the kind of quantum cosmological models that come out from it.

They touch on the Borde, Guth, Vilenkin theorem that apologists love to cite as evidence that the universe "must have had a beginning" and most importantly they explain why the theory doesn't necessarily lead to that conclusion.

There's a lot we don't know here, but this is an example of how science is progressing on the issue in cosmology rather than throwing our hands up in the air and saying "god did it".
