Geometric Matching of Local Static Regions in Cosmological Spacetimes with an Evolving Lapse
Seokcheon Lee
The generalized cosmological time (GCT) framework introduces a modified lapse function, N(t)\propto a^{b/4}, as a geometric extension of the standard FLRW description. Like other d…
A Unified Interpretation of Supernova, GRB, and QSO Time Dilation Signals in a Generalized Cosmological Time Framework
Seokcheon Lee
Cosmological time dilation (CTD) serves as a fundamental probe of cosmic expansion, historically verified through the characteristic (1+z) broadening of Type Ia supernova (SNe Ia)…
Revisiting Varying Speed of Light in Cosmology: Insights from the Friedmann-Lemaître-Robertson-Walker Metric
Seokcheon Lee
In the Friedmann-Lemaître-Robertson-Walker metric, a varying speed of light (VSL) reflects a change in the clock rate across hypersurfaces, described by the lapse function. This va…
Perturbation Theory in the Minimally Extended Varying Speed of Light (meVSL) Model
Seokcheon Lee
Cosmological perturbation theory provides a fundamental framework for analyzing the evolution of density fluctuations and gravitational potentials in the Universe. It plays a cruci…
3+1 formalism of the minimally extended varying speed of light model
Seokcheon Lee
The formalism provides a structured approach to analyzing spacetime by separating it into spatial and temporal components. When applied to the Robertson-Walker metric, it sim…
Cosmography of the minimally extended Varying Speed of Light Model
Seokcheon Lee
Cosmography, as an integral branch of cosmology, strives to characterize the Universe without relying on pre-determined cosmological models. This model-independent approach utilize…
Review on the minimally extended varying speed of light model
Seokcheon Lee
It has been known that dimensional constants such as , , , , and are merely human constructs whose values and units vary depending on the chosen system of measu…
