The study of the mathematical properties of black objects is a major research theme of contemporary theoretical physics. This review presents a comprehensive survey of the various versions of the first law and second law of black hole mechanics in general relativity and beyond. The emphasis is to understand how these laws can constrain the physics beyond general relativity.falseArticlehttps://arxiv.org/pdf/1905.04466157295321 May 20192363arJournal25WOS:000467567400001
