Brought to the stage of the Marylebone Theatre, the production retains the fable-like quality of the original; Samantha Spiro plays the narrator, telling the fable from a storybook with the help of only sparse props, mainly confined to an armchair. Bekenstein proved that in Einstein's gravity minimally coupled to one (or many) real, Abelian, Proca field, stationary black holes (BHs) cannot have Proca hair.

We present a survey of the known cosmological and black hole solutions in ghost-free bigravity and massive gravity theories. Physicist John Archibald Wheeler expressed this idea with the phrase "black holes have no hair", [1] which was the origin of the name. At the classical level, the two stars have the same gravitational potential, but at the quantum level, the potential depends on the star composition. Thus any black hole that has been isolated for a significant period of time can be described by the Kerr–Newman metric in an appropriately chosen reference frame. The first version of the no-hair theorem for the simplified case of the uniqueness of the Schwarzschild metric was shown by Werner Israel in 1967.We present the domain of existence of one family of KBHsPH, as well as its phase space in terms of ADM quantities.

This means that the spontaneous symmetry breaking associated with local U(1) cannot be realized in this theory. Dr Fiona Barry lifts the old stigma around menopause, she says knowledge is power during this new and lengthy phase of life.In a paper published in the journal Physical Review Letters, Michigan State University’s Professor Stephen Hsu and colleagues demonstrate that black holes are more complex than originally understood and have a gravitational field that, at the quantum level, encodes information about how they were formed. Here we provide details on their construction, discussing properties of the ansatz, the field equations, the boundary conditions and the numerical strategy. The purpose of this issue is to collect some of the interesting models of alternative compact objects and hairy black holes that the community has been studying in recent years, together with discussions of observations that can help discriminate these models. Featuring some of Australia's toughest animals, suspiciously hairy holes in the desert and a crash course on the wonderful world of the internet, this hilarious graphic novel will crack you up and take you on a 'kray-zay' ride - one the whole family will enjoy, hairy or otherwise.
