This research aims to demonstrate that a geometric modification of cosmic time can resolve significant cosmological tensions without relying on dark energy.
Developed a nonlinear time-curvature framework.
Distinguished observer clock-time from true cosmic evolution parameter.
Applied the mapping equation τₑ = t^α to model cosmic phenomena.
Utilized datasets including Pantheon+, SH0ES, and Planck for analysis.
Explored the implications of 'Golden Alpha' value for cosmology.
Resolved five major cosmological tensions without modifying FLRW metric.
Reproduced supernova Hubble diagram and matched SH0ES Hubble constant.
Extended cosmic age estimation to approximately 20 billion years.
Suppressed structure growth to align with DES/KiDS lensing results.
Provided a consistent alternative to ΛCDM’s linear-time cosmology.
