The Subjective Computable Universe
Marcus Hütter · WORLD SCIENTIFIC eBooks · 2012
Nearly all theories developed for our world are computational. The fundamental theories in physics can be used to emulate on a computer ever more aspects of our universe. This and the ubiquity of computers and virtual realities has increased the acceptance of the computational paradigm. A computable theory of everything seems to have come within reach. Given the historic progression of theories from ego- to geo- to helio-centric models to universe and multiverse theories, the next natural step was to postulate a multiverse composed of all computable universes. Unfortunately, rather than being a theory of everything, the result is more a theory of nothing, which actually plagues all too-large universe models in which observers occupy random or remote locations. The problem can be solved by incorporating the subjective observer process into the theory. While the computational paradigm exposes
