I note without really understanding an interesting new model where time is an emergent property rather than a fundamental feature of physics.
It is not reality that has a time flow, but our very approximate knowledge of reality. Time is the effect of our ignorance.
Time is so deeply fundamental to human experience that conceiving of reality otherwise seems beyond our capability to directly grapple with such a concept. We can consider anything with sufficient degrees of abstraction, increasingly distancing our thinking from that actual reality it attempts to represent.
Whether or not this new model will prove to have merit, it’s wonderful to see after so much research in fundamental physics for so many years that human imagination still concocts new ideas.
