Information-Probabilistic description of the Universe

We describe the universe as a single entangled ensemble of quantum particles. Total entropy of this world ensemble, which can be expressed as a sum of information, thermodynamic and entanglement components, is assumed to be always zero. This condition suggests information quantization, which we associate with Planck's action. Then the entropy neutrality condition for the universe leads to the zero-action principle. We show that main concepts of classical space-time and gravity naturally emerge in this picture. Generalized least action principle, which embraces maximal entropy principles of information theory, is introduced.
