| contents | <p>The problem of gravitational halos remains one of the central unresolved interpretational issues in modern cosmology. Within the standard ΛCDM framework, halo phenomena are attributed to the presence of an additional non-luminous material component—dark matter—introduced as an independent physical substance with its own dynamical properties. Alternative approaches, including modified gravity theories, alter the fundamental laws of interaction but often sacrifice universality or consistency with general relativity.</p> <p> </p> <p>In this work, we propose a different interpretation of halo phenomena within the framework of Finite-Relaxation Geometry (FRG), an interpretational extension of general relativity in which spacetime geometry possesses a finite relaxation time toward local Einstein solutions. In this approach, gravitational halos are not material components and not stationary states, but manifestations of slow, incomplete geometric relaxation following non-adiabatic gravitational events. We show that this interpretation naturally accounts for the spatial extent, stability, diversity, and formation-history dependence of observed halos without introducing new particles or modifying the Einstein field equations.</p> |
