This alternative cosmological model proposes a reinterpretation of the universe's apparent expansion by introducing a variable Planck length that decreases over time. Rather than attributing redshift solely to metric expansion, the model suggests that fundamental units of measurement evolve, which results in an apparent cosmological expansion when measured with today's standards. The emission time of light from distant objects is recalculated through a new equation that relates redshift with a modified time-dependent function. The model also redefines the comoving distance accordingly, aligning with this evolving metric framework.
