final sentence of conclusions:

"...our results show that the quantum geometry in the Planck regime serves as a ‘quantum bridge’ between large classical universes, one contracting and the other expanding."

words leading up to the above:

"...we constructed the physical Hilbert space, Dirac observables and semiclassical states, thereby extracting physics of the Planck regime, going significantly beyond the demonstration of singularity resolution..."

Quantum Nature of the Big Bang

Abhay Ashtekar, Tomasz Pawlowski, Parampreet Singh

4 Pages, 2 Figures

"Some long standing issues concerning the quantum nature of the big bang are resolved in the context of homogeneous isotropic models with a scalar field. Specifically, the known results on the resolution of the big bang singularity in loop quantum gravity are significantly extended as follows: i) the scalar field is shown to serve as an internal clock, thereby providing a detailed realization of the 'emergent time' idea; ii) the physical Hilbert space, Dirac observables and semi-classical states are constructed rigorously; iii) the Hamiltonian constraint is solved numerically to show that the big bang is replaced bya big bounce.Thanks to the non-perturbative, background independent methods, unlike in other approaches the quantum evolution isdeterministic across the deep Planck regime."

So Ashtekar has officially signed on deterministic bounce, connecting contracting regions to expanding ones.

Where I think this is leading is that he---or someone continuing his line of investigation---may eventually take issue with Stephen Hawking's claimed resolution of black hole information "loss". If there is a bounce in the hole then information that appears "lost" comes out on the other side of the Planck regime to an expanding continuation of spacetime. No loss, it's just a fork in the road of time.
