No Big Bang? Quantum equation predicts universe has no beginning...

If they're correct, the universe has no beginning and no end.

In physical terms, the model describes the universe as being filled with a quantum fluid. The scientists propose that this fluid might be composed of gravitons—hypothetical massless particles that mediate the force of gravity. If they exist, gravitons are thought to play a key role in a theory of quantum gravity.

In a related paper, Das and another collaborator, Rajat Bhaduri of McMaster University, Canada, have lent further credence to this model. They show that gravitons can form a Bose-Einstein condensate (named after Einstein and another Indian physicist, Satyendranath Bose) at temperatures that were present in the universe at all epochs.

Motivated by the model's potential to resolve the Big Bang singularity and account for dark matter and dark energy, the physicists plan to analyze their model more rigorously in the future. Their future work includes redoing their study while taking into account small inhomogeneous and anisotropic perturbations, but they do not expect small perturbations to significantly affect the results.

"It is satisfying to note that such straightforward corrections can potentially resolve so many issues at once," Das said.

Thing is, it doesn't address why all the movement in predictable patterns discovered by Edwin Hubble (the Hubble law).  I guess perhaps this quantum fluid and dark matter drive that?  But then...why always away from us?  Physics is hard and stuff.

You're on the right track -- the forces of quantum fluid and dark matter is pushing everything.

Will add a Reddit link if I find a good discussion of this there.
