It suggests that time is an emergent phenomenon that comes about because of the nature of entanglement. And it exists only for observers inside the universe. Any god-like observer outside sees a static, unchanging universe, just as the Wheeler-DeWitt equations predict.
Quantum Experiment Shows How Time ‘Emerges’ from Entanglement [blog post on the above]
The above seems to give credence to the idea that our Universe lives within a black hole…
