Self proclaimed intellectuals clutch their pearls of learning as faithfully as a hopeful child does their rosary.
There is no definitive concensus on the universes origin.
"...But actually, what lay people like me didn’t know 30 years ago is that a transformation was already happening in the physics community. How people were thinking about the big bang was shifting. The big bang no longer necessarily referred to the beginning. And there may not have been a beginning at all – at least not in the traditional terms.
There have been two changes to the way physicists think about this cosmological timeline. The first is that research on
inflationary models, which study the exponential expansion of space-time, indicate that inflation may be an eternal process. As in, the universe may not have had a beginning moment, and we may live in what is called an eternally inflating universe, one that was expanding exponentially even before what we call the big bang. Mathematically, this seems the most likely scenario – assuming inflation is correct.

Second, these days, people often use “hot big bang” to refer to a time period, rather than a single moment. The story goes that in the early stages of our corner of space-time, what we might call the visible universe, the universe was very hot and dense. This hot big bang era was filled with an energetic goo from which atoms would eventually emerge and begin to cluster, along with dark matter, into the structures we observe today: stars, galaxies, planets and, yes, people.
In a recent email to me and my editor, one of these people structures – a thoughtful reader – sent in a question that points to this
transformation in how we think about the big bang. The reader noted that, for a while, it was fashionable to publish articles about the big bang and these days there are fewer. While I can’t speak to publishing choices by the editors at this magazine or any other, I can say that in recent years, there has been more (if not total) consensus in the cosmology community about the likely scenario for the inflationary universe – that our space-time went through a period of rapid, exponential expansion. A plethora of data supports the inflationary picture, which mathematically favours an eternal scenario.
There are, of course, detractors. Paul Steinhardt, one of the early thinkers on inflation, has since become one of its most vocal critics. But even in his competitor model of the universe, the big bang is replaced by a
big bounce and a cyclic universe. The key point, ultimately, is that physicists don’t like singularities, and the search has always been on for a more satisfying model. Much as the idea of a “beginning moment” might satisfy the intuition we have developed in a world where some of the most dominant religious traditions teach us that there is a definitive beginning, from a scientific point of view, the singularity is a mathematical problem to be solved.
Models of the very early universe are hard to test directly. That doesn’t stop people from trying..."
PART of what turned me into a theoretical cosmology enthusiast as a child was watching the documentary A Brief History of Time and hearing about the mystery around the big bang. It showed how the equations that we use to describe space-time broke down into a singularity when we ran time all the...
