But the singularity is the only known origin of this universe, no? Else we might as well speculate about a (to us) supernatural world apart from our universe. We know there was a big bang, we know it came from a singularity . We may deduce that all the energy produced was what we can currently observe and measure, no? To me that presents as a mega-nova, a instantaneous mega quantum event producing all existent energy, from which our current universe evolved.
