The energy conditions and model selection in the local Universe
Namit Chandak, Fulvio Melia, Junjie Wei
The four principal energy conditions (ECs) in general relativity prohibit negative energies, repulsive gravity and superluminal energy flows. One must invoke exotic matter to viola…
The JWST early galaxy crisis resolved by a reionization degeneracy
