Open Paradoxes of Cosmology and the Dynamic Cosmic Medium Model

Contemporary cosmology achieves considerable precision in describing manygravitational and astrophysical phenomena, yet when extended to galactic,cosmological, and extreme scales it encounters problems that are often interpretedthrough several separate auxiliary constructions. This article presents the DynamicCosmic Medium Model (DKMM) as an alternative conceptual framework in whichthe same difficulties are interpreted not as a consequence of the geometry of emptyspace, but as a consequence of the state of a real medium that fills space.In DKMM, time is absolute, space is not a physically active empty background but aframework filled with a dynamic cosmic medium, and vacuum does not represent azero state but rather the equilibrium state of the medium with a positive base level.Stable structures are not understood as objects inserted into space, but asorganized states of the medium whose origin and stability are connected withcirculation. Gravitational and cosmological phenomena are interpreted in thisframework as consequences of state gradients of the medium, modulation ofprocesses, and long-term evolution of structures in an active environment.The article systematically goes through five main areas in which the currentstandard framework encounters conceptual limits: galaxy rotation, acceleratedexpansion, limiting collapse states and the beginning of cosmic evolution, themismatch between gravity and quantum description, and the problem of large-scalehomogeneity. The aim is not to claim that DKMM is an experimentally confirmedtheory, but to show that, as an alternative model, it offers a more unified andphysically more direct interpretive axis for phenomena that are today oftenexplained through several separate hypothetical constructions.
