TL;DR
This paper applies an extended 5D general relativistic theory to estimate the minimum sizes of galaxies like the Milky Way, Andromeda, and M87, achieving results consistent with observations.
Contribution
It introduces a 5D Ricci-flat spacetime framework to extend general relativity and applies it to galactic size estimations, aligning theory with empirical data.
Findings
Estimated galactic size lower limits match observations
Extended theory provides a new approach to galactic scale calculations
Results support the validity of the 5D extended relativistic model
Abstract
Considering a five-dimensional (5D) Riemannian spacetime with a particular stationary Ricci-flat metric, we have applied the recently developed Extended General Relativistic theory to calculate the lower limit for the size of some relevant galaxies: the Milky Way, Andromeda and M87. Our results are in very good agreement with observations.
