Abstract A set of infinitesimal Virasoro L ⊗ Virasoro R diffeomorphisms are presented which act non-trivially on the horizon of a generic Kerr black hole with spin J. The covariant phase space formalism provides a formula for the Virasoro charges a

Abstract We describe the conformal symmetries of asymptotically flat spacetime. These represent an extension of the BMS group that we call the conformal BMS group. Its general features are discussed.

Abstract It is shown that black hole spacetimes in classical Einstein gravity are characterized by, in addition to their ADM mass M, momentum P → $$ \overrightarrow{P} $$ , angular momentum J → $$ \overrightarrow{J} $$ and boost charge K → $$ \

First published in 1973, this influential work discusses Einstein's General Theory of Relativity to show how two of its predictions arise: first, that the ultimate fate of many massive stars is to undergo gravitational collapse to form 'black holes';

In the classical theory black holes can only absorb and not emit particles. However it is shown that quantum mechanical effects cause black holes to create and emit particles as if they were hot bodies with temperature\(\frac{{h\kappa }}{{2\pi k}} \a

We address the question of the title from the scientific, economic, and cultural points of view, and argue strongly for a positive answer. We respond to various issues that have been raised.

Perché esistiamo? Da dove veniamo? Stephen Hawking, dalla frontiera della fisica e dell'astrofisica moderne, ha ripercorso le più profonde risposte filosofiche elaborate nel corso della Storia umana a queste domande e ce ne ha restituito poi un'avv
