Abstract: This study tackles the impact dark energy in different systems by a simple unifying formalism. We introduce a parameter space to compare gravity tests across all cosmic scales, using the McVittie spacetime (MCV), that connect spherically symmetric solutions with cosmological solutions. By analyzing invariant scalars, the Ricci, Weyl, and Kretschmann scalars, we develop a phase-space description that predicts the dominance of the Cosmological Constant. We explore three cases: (1) the local Hubble flow around galaxy groups and clusters, (2) spherical density distributions and (3) binary motion. Our results show that galaxy groups and clusters exhibit Kretschmann scalar values consistent with the Cosmological Constant curvature, indicating where dark energy dominates.

This study focuses on understanding the impact of dark energy in various systems using a simple unifying formalism. The authors introduce a parameter space that allows for a comparison of gravity tests across all cosmic scales, using a mathematical framework called the McVittie spacetime (MCV). MCV connects spherically symmetric solutions with cosmological solutions, aiding in the analysis of invariant scalars such as the Ricci, Weyl, and Kretschmann scalars.
Through their analyses, the authors develop a phase-space description that predicts the dominance of the Cosmological Constant. They explore three specific cases to support their findings: (1) the local Hubble flow around galaxy groups and clusters, (2) spherical density distributions, and (3) binary motion. The results indicate that galaxy groups and clusters exhibit Kretschmann scalar values consistent with the curvature expected from the Cosmological Constant, suggesting that dark energy dominates in these regions.
