Re: Two solar masses (in energy) escaped
One theory to explain how gravity (gravitons if those exist) seemingly escapes the black hole is that it's space itself that holds and propagates (sort of remembers) the gravity field. It does not need to be connected to the mass inside. Within the space around the black hole there is then information about how much mass is inside the event horizon. But that is just one theory. It don't fully explains gravitons etc. there is a lot of phenomenas where quantum theory and general relativity don't play with each other.
