The Sgr*A black hole is 4.2 million solar masses or about 13 million km Schwarzschild radius. A signal at the speed of light can easily move across or around the horizon within a day. Yet I admit my conjecture here could easily be wrong. LC -- You received this message because you are subscribed to the Google Groups "Everything List" group.
