An infinite progress

[vulcanlogician]

So does, "before the big bang, the energy required to create the universe was spat out by the great Nordic serpent." But scientists don't entertain the Nordic serpent hypothesis (or yours) because there isn't good evidence backing it up... they aim for a degree of accuracy. A good scientific theory must "work" too, in the sense that it conforms with logic and evidence. Adding layers of accuracy, correcting errors and misconceptions (in a rinse/repeat fashion) is what science does next.

BTW, it is possible that the net energy of the universe is zero, so the Nordic serpent didn't really have to do anything

But the serpent is way cooler.
