Astronomers have used the Hobby-Eberly Telescope at The University of Texas at Austin's McDonald Observatory to measure the mass of what may be the most massive black hole yet—17 billion Suns—in galaxy NGC 1277. The unusual black hole makes up 14 percent of its galaxy's mass, rather than the usual 0.1 percent. This galaxy and several more in the same study could change theories of how black holes and galaxies form and evolve. The work will appear in the journal Nature on Nov. 29.
great article. Only 17 billion suns? Still the black hole is only 14% of the total mass of the entire galaxy. If it indeed consumes the rest of its galaxy, it will be 120 billions times the size of our sun, then with nothing to feed on, it will go completely dark and wander around until it interacts with other galaxies or other rogue black holes.
I do believe that black holes have no limit as to size. We are made up of black hole stuff, and we will return one day to another black hole.
