Cosmological Redshift Without Expansion presents a physical reinterpretation of cosmological redshift within the framework of Quarkbase Cosmology. In contrast to the standard geometric interpretation based on expanding space, the redshift is explained as a consequence of the evolution of a real physical medium, the Ψ-field, which underlies light propagation and local measurement processes.
Light is described as a non-dissipative luminal resonant mode of this medium, while frequency is defined operationally through its coupling to local material resonators. The redshift is shown to arise from differences between the state of the Ψ-field at emission and observation, summarized by the relation:
1 + z = n(tobs) / n(temit)
This approach reproduces the observed redshift–distance relation without invoking expanding space, accelerated cosmic expansion, or dark energy, and reframes cosmological redshift as a direct probe of the physical state and temporal evolution of the universe’s underlying medium.
