Constraints on Dark Energy Models from Weak Gravity Conjecture
-
Abstract
We study the constraints on the dark energy model with constant equation of state parameter w=p/ρ and the holographic dark energy model by using the weak gravity conjecture. The combination of weak gravity conjecture and the observational data gives w<-0.7 at the 3σ confidence level. The holographic dark energy model realized by a scalar field is in swampland. -
