Episode notes

When i first heard about constructor theories, not that old, writers just a few years ago. A, i guess my question was, like, what is the constructor that picks up the earth and moves it to another point in its orbit? That's kind of an interesting question, sure. Ok, final e about the solar system, before we move on to other topics, just, and this is like the dumbest question, just for clarifying purposes. And that's something that maym not be true er. Andit will become clear in future whether it is.

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.
