Infighting over "inflation" & the Big Bang...they can't even agree....what does that tell you? I've known of this infighting since 2010 when Discover Magazine ran an article about how the newer mathematics doesn't support the inflationary theory required for the big bang...PASS THE POPCORN & sit back and watch the ring side fight over the big bang by evolutionary cosmologists... enjoy...
"Stephen Hawking and his fellow scientists have written an angry letter responding to a recent Scientific American article about how the universe began. In it, they declare their “categorical
disagreement” with several of the statements made, and explain why the theory of inflation is still one of the best models for the origin of the cosmos.
The article in question was published in February. Titled “Pop Goes the Universe,” physicists Anna Ijjas, Paul J. Steinhardt, Abraham Loeb examine the latest measurements from the European Space Agency relating to cosmic microwave background (CMB).
CMB is the oldest light in the universe—light emitted just after the Big Bang around 13.7 billion years ago. In 2013, a map of the CMB appeared to show how the universe inflated extremely fast, before settling down to become the universe we see today. This, many experts said, backed up models relating to inflation theories, where the universe expanded exponentially fast a fraction of a second after the Big Bang.
However, Ijjas, Steinhardt and Loeb disagreed with this interpretation. “If anything, the Planck data disfavored the simplest inflation models and exacerbated long-standing foundational problems with the theory, providing new reasons to consider competing ideas about the origin and evolution of the universe,” they write.
The physicists argue that since the 2013 map was produced, more precise data has been gathered. And this data, they say, adds more evidence to the argument that the Big Bang and inflation do not adequately explain how the universe started. “Yet even now the cosmology community has not taken a cold, honest look at the big bang inflationary theory or paid significant attention to critics who question whether inflation happened,” they say.
Instead, they claim the idea of a “big bounce” is a more likely scenario. In this theory, the universe works on a cyclical basis of expansion and contraction. At the moment, it is expanding. However, when it runs out of energy (or whatever happens to stop its expansion), it will start contracting. Eventually, it will get to the point where it is so small it starts expanding again.
They point to
several flaws in inflation theory,
*including that we are yet to discover primordial gravitational waves—ripples in spacetime created by the Big Bang.
*Another problem is that inflation requires the existence of “inflationary energy,” for which there is no direct evidence.
“Given all these problems, the prospect that inflation did not occur deserves serious consideration,” they write. “Today we are fortunate to have sharp, fundamental questions imposed on us by observations. The fact that our leading ideas have not worked out is a historic opportunity for a theoretical breakthrough. Instead of closing the book on the early universe, we should recognize that cosmology is wide open.” msn

Q: How's this for a BIG BANG?
And God said,
Let there be light:
and there was light.
