The Origin of Physical Laws and Sensations

Bruno Marchal, IRIDIA, Université de Bruxelles,
"I will first present a non constructive argument showing that the mechanist hypothesis in cognitive science gives enough constraints to decide what a "physical reality" can possibly consist in. Then I will explain how computer science, together with logic, makes it possible to extract a constructive version of the argument by interviewing a Modest or Löbian Universal Machine. Reversing von Neumann probabilistic interpretation of quantum logic on those provided by the Löbian Machine gives a testable explanation of how both communicable physical laws and incommunicable physical knowledge, i.e. sensations, arise from number theoretical relations."

Paper explores Marchal's ideas on how our physical laws and understanding of our perception of reality can be derived from his "comp" theory, often discussed with his participation on the Everything List.

Universal Dovetailer Concept

The idea of the Universal Dovetailer (UD), is basically the idea that there is a simple program that could list and execute every possible program that could run on a universal computer, which is a computer capable of running everything that is computable. In theory, a universal computer running a UD program given sufficient time and resources would create every experience and reality that is computable.

Mangled Worlds Quantum Mechanics

"This variation on the many worlds interpretation of quantum mechanics allows us to derive the Born probability rule via finite world counting and no new physics."
