Potential Evidence for Evolving Spacetime Dimensions from DESI

Abstract

Recent results reported by the Dark Energy Spectroscopic Instrument (DESI) suggest that Dark Energy (DE) may be weakening over time. The hypothetical time-dependence of DE raises a major challenge to standard cosmology, which is built on the assumption that DE represents the cosmological constant (CC) of Einstein’s equations. Here we point out that DESI’s findings reinforce the conjecture that, a) well above the range of electroweak interactions, spacetime dimensionality is continuous and runs with the observation scale, and b), the energy content of the CC stems from the cumulative contribution of energies stored in the fractal structure of Dark Matter/Cantor Dust.
