Present status of the Penrose inequality

Abstract: The Penrose inequality gives a lower bound for the total mass of a spacetime in terms of the area of suitable surfaces that represent black holes. Its validity is supported by the cosmic censorship conjecture and therefore its proof (or disproof) is an important problem in relation with gravitational collapse. The Penrose inequality is a very challenging problem in mathematical relativity and it has received continuous attention since its formulation by Penrose in the early seventies. Important breakthroughs h… Show more

“…A review of the status of WCC and the Penrose inequality appears in Refs. [2,3] In this paper we study a generalization of this inequality for asymptotically anti-deSitter (AAdS) spacetimes in 4-spacetime dimensions. This requires definitions of AAdS data and quasi-local mass.…”

“…An excellent survey of this conjecture is found in [24]. Suppose that the Cauchy data (M 3 , g, k) is complete, satisfies the nonnegative energy density condition µ ≥ |J|, and is Schwarzschild at infinity with total mass m in a chosen end.…”

“…Penrose's heuristic argument for a future apparent horizon in this conjecture is described in more detail in [5] and [24] but roughly goes as follows: If, as is generally thought, asymptotically flat spacetimes eventually settle down to a Kerr spacetime [16], then in the distant future inequality 10 will be satisfied since explicit calculation verifies this fact for Kerr spacetimes, where A is the area of the event horizon. Given that some energy may radiate out to infinity, the total mass of these slices of Kerr may be less than the original total mass.…”

“…This result was proved by [27] and [7]. The general case remains open, see the review article [29]. Finally, we have discussed the concept of total energy and linear momentum of an isolated system.…”

“…Integrating this equation in R 3 , using for the first term in the right-hand side the Gauss theorem, the condition ψ → 1 as r → ∞ and the expression (1.23) for the energy we finally obtain 29) where dv 0 is the flat volume element. This formula proves that for metric of the form (1.17) we have E ≥ 0 if R ≥ 0 and E = 0 if and only if h ij = δ ij .…”
