From Technology Review:
Shu’s idea is that time and space are not independent entities but can be converted back and forth between each other. In his formulation of the geometry of spacetime, the speed of light is simply the conversion factor between the two. Similarly, mass and length are interchangeable in a relationship in which the conversion factor depends on both the gravitational constant G and the speed of light, neither of which need be constant.
So as the Universe expands, mass and time are converted to length and space and vice versa as it contracts.
This universe has no beginning or end, just alternating periods of expansion and contraction. In fact, Shu shows that singularities cannot exist in this cosmos.
But what about the cosmic microwave background, considered the best evidence for the Big Bang?
How it might arise in Shu’s cosmology isn’t yet clear but I imagine he’s working on it.

I’m not about to jump on the bandwagon of any new cosmology, but I do think it is interesting that new ones keep coming out.
What does that tell us about the current Standard Model?
Perhaps it is not as factual as everyone would like to think.
Obviously there are some scientists, even secular scientists like this guy, who see the holes in it.
There are lots of problems with the Standard Model, and I know of no physicists who thinks otherwise.

Of related note;
To dodge the Theistic implications of a beginning for the universe many times Materialists/Atheists also try proposing a universe which expands and contracts infinitely. Even at first glance, the ‘oscillating universe’ conjecture suffers so many questions from the second law of thermodynamics (entropy) as to render it effectively implausible as a serious theory, but now the oscillating universe conjecture has been totally crushed by the hard evidence for a ‘flat’ universe found by the ‘BOOMERANG’ experiment.
A ‘flat universe’, which is actually another very surprising finely-tuned ‘coincidence’ of the universe (since the universe could, theoretically be an almost infinite number of things other than flat), means this universe, left to its own present course of accelerating expansion due to Dark Energy, will continue to expand forever, thus fulfilling the thermodynamic equilibrium of the second law to its fullest extent (entropic ‘Heat Death’ of the universe).
This decay of the universe towards ‘heat death’ is a Theistic presupposition:
Well, if I wanted to go to Whimpering Chutney, I wouldn’t start from ‘here….’
