Supermassive black hole
Measurements by the STIS instrument also allowed astronomers to determine the movement of the blue stars and therefore pinpoint the black hole's mass.
This proved conclusively that it really is a supermassive black hole, with a mass 140 million times that of our Sun - three times more massive than previous estimates.
Until these observations, it had been impossible to rule out some highly unlikely alternatives for the object in the centre of the galaxy - including an extremely dense star cluster, says team member John Kormendy at the University of Texas, US.
"Nailing the black hole in Andromeda" will be remembered as one of Hubble's most important findings, Kormendy says. "It makes us much more confident that the other central dark objects detected in galaxies are black holes too."

Also, remember I mentioned consistency between parts of theories. In grav's gravity thread, you have the whole universe 'inside' a Black Hole, but in this thread you are saying that event horizons don't exist and there is no 'inside' to a Black Hole.
