Does the Borde-Guth-Vilenkin theorem definitively demonstrate that the Universe cannot be past-eternal, whatsoever? Does it not assume a classical space-time while the real world requires Quantum mechanics?
Are there successful models in Cosmology that are Past-Eternal?
Why might Alan Guth say the Universe might be eternal in the past, when he himself wrote a theorem in 2003 saying it most definitely isn't?
