In colloquial terms, the main achievement of our recent CQG article is simple to state: We have proven that the angular momentum J of an axially symmetric black hole (the Noether current) with surface area A satisfies the bound.equation Walter CQG+ post

Here \Lambda is the cosmological constant –  a standard ingredient in Einstein’s Continue reading
