Conceptual analysis outlines a fourth spatial dimension coupled to the observable universe, suggesting unified mechanisms for quantum entanglement, dark matter, and cosmic expansion.
The Exoverse Theory is a speculative fourth-dimensional framework developed by David S. Thompson of Waterloo, Ontario, Canada. The theory proposes that the observable universe is a three-dimensional domain embedded in and dynamically coupled to a fourth spatial dimension called the Exoverse. The Exoverse is described as a physical environment containing matter, energy, field activity and gravitational structure. It is not a black hole or a larger three-dimensional universe surrounding our own. This technical conceptual essay examines whether interactions with the Exoverse could provide a connected explanation for quantum entanglement correlations, accelerated cosmic expansion, dark-matter phenomena, the comparative weakness of gravity, missing supersymmetric particles and the origin of the Big Bang. The paper presents the theory’s foundational postulates, a preliminary 4+1-dimensional mathematical framework, possible observational consequences and the requirements necessary to develop the proposal into a quantitatively testable physical theory.
