Marginalia: The Geometry of Closed Flows

This Habr article explores fundamental questions regarding the geometric formulation of relativistic physics. The author challenges the traditional approach where spacetime structure with a Lorentzian metric is taken as a given. In modern physics, the electromagnetic field is treated as a secondary object imposed on an existing geometric background. The author questions why physical geometry must be based on Lorentzian spacetime from the outset and proposes rethinking the sequence of mathematical descriptions for physical phenomena. The text is theoretical in nature and invites readers to discuss the nature of space, time, and fundamental fields, offering a different perspective on the standard postulates of general relativity. It is a profound reflection on the mathematical foundations of the universe, likely to interest specialists in theoretical physics and mathematics.
