Decoherence and the Many-Worlds Interpretation

This chapter explores the complex theories of decoherence and branching within quantum physics, focusing on how decoherence increases with particle count and manifests differently across multiverse branches. It delves into the implications of these concepts on history structures in a finite Hilbert space, as well as the dynamics of coherence and classical observations. Additionally, the chapter considers the interplay between time's arrow and various interpretations of quantum mechanics, advocating for open dialogue among differing theories.
