Episode notes

Quantum gravity could be used to create a thermodamic cycle within things like the maxel semon set up or the silan engine set up. There are fluctuations on the microscopic scale, which may have implications for information theory and work extraction. And i apologize for not having a better understanding of what you've said about this, but, i mean, i have the vague impression that a constructor theory is relevant here somehow.

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.
