The universe as a thermal universal Turing machine
Alexandre Harvey-Tremblay · 2017
I suggest and formalize an alternative approach to understand the universe in which a large blob of irreducible facts, rather than a small list of axioms, define the theory. The blob of facts is given a physical interpretation when it is structured as a Gibbs ensemble. In the case where the facts are logically verifiable, the Gibbs ensemble describes a thermal universal Turing machine which spawns the whole system. The Lagrange multipliers of the partition function are the Planck units. The background, a thermal spacetime, emerges as a consequence of the limits applicable to the conjugate pairs. The background obeys Special and General relativity, dark energy, the arrow of time, the holographic principle, the Schrödinger equation and the Dirac equation.
