Abstract

Although the basic approach of the many-worlds interpretation is that the ontology of our universe is a unitarily evolving highly entangled wavefunction, we live in a world in which we only perceive a tiny part of the global wavefunction, and the quantum state corresponding to our world does not evolve unitarily, making our world an effectively open system. Recently, the common approach that within a world conservation laws hold only for an ensemble of measurements was questioned. The paper analyzes how this can affect viewing worlds as open systems and proposes a possible resolution of the unitarity puzzle.
