Multidimensionality and Alternate Reality: Theoretical Frameworks of Parallel Universes
Abstract The exploration of multidimensionality and alternate realities within the framework of parallel universes represents one of the most compelling intersections of physics, cosmology, and philosophy. This study synthesizes theoretical perspectives from quantum mechanics, string theory, and cosmological inflation to examine how higher‑dimensional structures may underpin the existence of alternate realities. By analyzing quantum decoherence and the Many‑Worlds Interpretation, the paper highlights how branching quantum states could manifest as distinct universes. String theory’s proposal of compactified dimensions and brane cosmology further expands the possibility of universes with divergent physical laws. The discussion integrates mathematical formulations of dimensional compactification with philosophical considerations of identity, causality, and epistemology, emphasizing the challenges of empirical validation. While direct observation remains unattainable, indirect approaches—s...
