The Hilden Cosmology v2.0

The Hilden Cosmology v2.0 is a non-dynamical interpretive framework for understanding large-scale cosmic behaviour through informational access rather than geometric evolution. It extends the informational-time concept introduced in the Hilden Principle, where time is defined as T = dφ/dτ, with φ increasing monotonically along every physical worldline. The framework explores how observers may experience cosmological phenomena through the evolution of informational access while remaining fully compatible with General Relativity (GR). Version 2.0 introduces the concept of gravitational spheres as an interpretive model for extremely compact objects. Within this perspective, black holes are described as compact cores surrounded by gravitationally dominated regions whose observational influence may extend far beyond the physical size of the core itself. The framework examines light bending, observed black-hole structures, and black-hole mergers through this interpretive lens without modifying GR or established gravitational-wave physics. The cosmology also explores informational interpretations of redshift, periodic astrophysical sources, large-scale cosmic structure, and hypothetical superluminal observation while maintaining consistency with the causal structure of relativity. In addition, the framework considers the possibility of a gravitationally dominated compression limit and introduces the Hilden Explosion as a purely interpretive and hypothetical concept describing a potential informational transition between cosmological epochs. It is not presented as a model of the Big Bang, a physical mechanism, or a replacement for standard cosmology. The model is conceptual and complementary: it introduces no new physical fields, modifies no Einstein equations, does not replace ΛCDM, and does not compete with established gravitational theory. Instead, it offers an alternative perspective on how observers may perceive the universe through the evolution of informational access and gravitational structure.
