I draw your attention to following quote:
The Universe doesn't end, as counter-intuitive as this seems. Once again, language confuses concepts. We speak of a ‘Big Bang' but don't mean a ‘bang' like an explosion, which has a centre and a shock wave that moves spherically out into air from the explosion.
Instead, the ‘Big Bang' happened everywhere in the Universe at once, with no centre. Shortly after the ‘Big Bang', density and pressure of the Entire Universe were the same everywhere. So, pressure difference could not possibly create an explosion. The ‘Big Bang' wasn't a bang at all.
Humm... so the universe appeared everywhere all at once. Sounds like the Genesis account to me.
