There are many proposals to describe what's going on, ithing this goes back toa confinement. We don't really have a watertight way of just making predictions in this domains that are thentestable and at least can help us rule out a class of models for gravitary. I'm one of those people who expect gra to be modified in a way that will become quantum, rather than quantum theory becoming classical.
Traditional physics works within the “Laplacian paradigm”: you give me the state of the universe (or some closed system), some equations of motion, then I use those equations to evolve the system through time. Constructor theory proposes an alternative paradigm: to think of physical systems in terms of counterfactuals — the set of rules governing what can and cannot happen. Originally proposed by David Deutsch, constructor theory has been developed by today’s guest, Chiara Marletto, and others. It might shed new light on quantum gravity and fundamental physics, as well as having applications to higher-level processes of thermodynamics and biology.
