The Cosmological Constant is Probably Zero, and a Proof is Possibly Right
Zhong Chao Wu
Hawking proposed that the cosmological constant is probably zero in quantum cosmology. Duff claimed that Hawking's proof is invalidated. Using the right configuration for the wave…
Creation of Kerr-de Sitter Black Hole in All Dimensions
Zhong Chao Wu
We discuss the quantum creation scenario of a Kerr-de Sitter black hole in all dimensions. We show that its relative creation probability is the exponential to the entropy of the b…
The Topological Origin of Black Hole Entropy
Zhong Chao Wu
In gravitational thermodynamics, the origin of a black hole's entropy is the topology of its instanton or constrained instanton. We prove that the entropy of an arbitrary nonrotati…
Can Black Hole be Created at the Birth of the Universe?
Zhong Chao Wu
We study the quantum creation of black hole pairs in the (anti-)de Sitter space background. These black hole pairs in the Kerr-Newman family are created from constrained instantons…
Entropy of a Black Hole with Distinct Surface Gravities
Zhong Chao Wu
In gravitational thermodynamics, the entropy of a black hole with distinct surface gravities can be evaluated in a microcanonical ensemble. At the level, the entropy becomes…
Quantum Creation of BTZ Black Hole
Zhong Chao Wu
The constrained instanton method is used to study quantum creation of a black hole. It is found that the relative creation probability is the exponential of the negative sum…
