The wave function and probability of a universe with a black hole are calculated at the W K B level. The probability of a black hole creation is the exponential of one quarter of the sum of areas of the black hole and cosmological horizons. One quarter of this sum is the total entropy...
Less known is the fact that a black hole can be produced by the quantum process of pair creation in external fields. These black holes may have a mass much lower than their astrophysical counterparts. This mass can be of the order of Planck mass so that quantum effects may be important. ...
And from the sounds of things, to take her to the extreme outskirts of what the locals called a town. She lifted her foot, pushing aside the mosquito net around the bed and looked out of the open veranda door on the other side of the room. The ocean crept up on the black sand not...
Although these quantum effects violate the classical law that the area of the event horizon of a black hole cannot decrease, there remains a Generalized Second Law:S+1/4A never decreases whereS is the entropy of matter outside black holes andA is the sum of the surface areas of the event ...

stationary action condition is crucial to the validation of the WKB approximation. We are going to work at the WKB level for the problem of quantum creation of a black hole pair. A main unresolved problem in quantum cosmology is to generalize the no-boundary proposal for an open universe. Wh...
Erratum: Black Hole Particle Emission in Higher-Dimensional Spacetimes [Phys. Rev. Lett. 96, 071301 (2006)] In this Letter, Parikh–Wilczek tunnelling framework, which treats Hawking radiation as a tunnelling process, is extended, and the emission rate of a charg... V Cardoso,M Cavaglià,L...

An additional "integration constant" in the Friedmann equation -accompanying a term which dilutes like radiation- describes the tidal force in the fifth direction and arises from the mass of a spherical object inside the bulk. This could be a 5-dimensional black hole or a "parallel" brane-...
“Black Hole's team has been a pleasure to work with. They have created fantastic video recipes for our website and took great pictures of our premises and dishes. Besides, they have delivered great video contents of our opening party. I am glad I decided to hire them and I can't reco...
