The Fermionic Universe Hypothesis (FUH): Revision of Cosmological Foundations and the Physical Nature of the Medium

This paper presents a revision of fundamental concepts regarding the structure of space-time. The FUH hypothesis proposes a shift from geometric abstraction toward a physically dense medium—a fermionic condensate. The proposed model eliminates singularities in cosmological solutions and explains the nature of the hidden mass through the fundamental constant m-ψ.
