So, was there a Big Bang from which the universe expanded into the present form.? The Friedmann-Lemaître-Robertson-Walker metric, analysis of light spectrum from galaxies and the cosmic microwave background radiation all indicate that there was an initial state of infinite density and temperature.
But computational physicists like Neil Turok believe that the universe is anādi (without begining or end) and Big Bang is just one stage in infinite cycles of expansions and contractions.
Within a school of string theory known as m-theory, Turok said, “the seventh extra dimension of space is the gap between two parallel objects called branes. It’s like the gap between two parallel mirrors. We thought, What happens if these two mirrors collide? Maybe that was the Big Bang.[Physicist Neil Turok: Big Bang Wasn’t the Beginning]
The Catholic Church, always in search of Galileos, is against this theory. It is not that the priests have groked D-branes and NS-branes and all the extra dimensions to come with a scientific objurgation, instead they just dusted a timeless tactic: it goes against the scriptures
Wired: The Catholic Church hasn’t been very receptive to your ideas, either.
Turok: I think they like the Big Bang for obvious reasons. It’s a creation event, and they find that appealing. Whereas if you talk to most physicists, they’d prefer that there was not a creation event, because there are no laws of physics that indicate how time could begin. I’m not motivated by [theological considerations]. I’d be perfectly happy with a mathematically precise description of how time began. I see science and religion as being two completely different things. I don’t see science as relevant to the question of whether or not there’s a God.[Physicist Neil Turok: Big Bang Wasn’t the Beginning]
