Thermodynamics and weak cosmic censorship conjecture of dRGT black holes
As one of the revised gravity theories.the theory of mass gravity is of great significance for exploring the accelerated expansion of the universe and explaining the problems of dark energy and dark matter.In this paper we study whether the first law of thermodynamics,the second law of thermodynamics and the weak cosmic supervision hypothesis are valid for the spherically symmetric black holes under de Rham-Gabadadze-Tolley(dRGT)mass gravity in conventional phase space.The influence of the differential change of entropy with the change of event horizon rd,and the influence of dimensionless free parameters α,β and graviton mass related to dRGT black hole on the image are explored.In the research process,the first law of black hole thermodynamics is verified by introducing the energy-momentum relationship of scalar particles,and the second law of black hole thermodynamics is verified by observing the influence of event horizon on the differential change of entropy.The study finds that the black hole absorbs particles at the same time,its event radius always exists,so that the singularity is never exposed.The results show that the first law of thermodynamics,the second law of thermodynamics and the weak cosmic supervision hypothesis are valid for the spherically symmetric black holes under dRGT mass gravity.
