Description

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.
