Changing Acceleration Rate (Cosmological Constant) Endogenous to Empirical Fractal Cosmology Model

This paper supplements the author’s fractal-cosmology paper by discussing recent DESI Survey observations that suggest the cosmological constant (lambda) may not be constant throughout the universe's evolution and may be weaker than it was earlier in the universe’s evolution. While these findings are at most a 4.2 sigma, this observation is extraordinary and demands an explanation.

In the author’s 2024 paper, Experiment on Inverted Fractal Corresponds with Cosmological Observations and Conjectures, the changing acceleration rate of expansion with respect to time and distance was empirically found to be a property of a growing fractal, along with Hubble-Lemaitre and accelerated expansion. In this paper, this finding was re-presented in the context of the DESI observations. The fractal, the geometry of our time, explains and predicts, independently, these phenomena and thus should be part of the discussion.
