The universe was quiet, vacuous. Very slowly, a weak attraction brought them together, creating a collision that made particles and energy.

They are only attempting to explain the evolution of the universe between now and the collapse, whereas we showed how this can be embedded in a larger cyclic scenario that leads to an eternal universe.

The pattern in which photons are blocked or not blocked had never really been computed. In the laboratory, we were able to construct a device that was effectively like doing a computer simulation to see the patterns of transmission.

Controlled light can be directed, switched and processed like electrons in an electronic circuit, and such photonic devices have many applications in research and in communications.

Because their proposal is based on rather specific models and assumptions and their is no current evidence for it, I would say it logically possible, but not compelling.

The search for a structure that blocks the passage of light in all directions has fascinated physicists and engineers for the past two decades.
