The dominance of dark energy in the universe has necessitated the introduction of a repulsive gravity source to make q0 negative. The models for dark energy range from a simple term to quintessence, Chaplygin gas, ...
Some Consequences of a Universal Tension Arising from Dark Energy for Structures from Atomic Nuclei to Galaxy Clusters

Sivaram, C; Arun, K; Kiren, O. V (Bentham Open, 2013-11-29)

In recent work, a new cosmological paradigm implied a mass-radius relation, suggesting a universal tension related to the background dark energy (cosmological constant), leading to an energy per unit area that holds for ...
