I don't really understand what you're trying to say. I think there's two things going on in your comment: you want more information about emergent theories, and you want more information about how time emerges in a theory that is symmetrical under time reversal. For the first, perhaps you should try Sabine Hossenfelder's video and video-transcript at <https://backreaction.blogspot.com/2020/04/what-is-emergence-...> first, rather than something more technical. For the second: your paraphrasing, particularly "if you disagree your logic is broken" is in my view unfair to the quoted scientists…

> (or at all) Rovelli's position is that time is not fundamental, not that it does not exist. It emerges from something more fundamental. That is, he argues that there exists a theory (or family of theories) from which one can derive both General Relativity and Relativistic Quantum Field Theory in their effective limits, and that such a theory does not need to be paramaterized by time (or more broadly, does not need to explicitly reference the notion of time at all). More precisely, he and Connes propose[1] that statistical regularities in a generally covariant quantum system (our block…
