Will a black hole 500 billion times the mass of the sun suck the galaxy away?

500 million times it hasn't been found so big. If there is, the black hole with the largest mass that has been discovered now is 3.5 billion light years away from the earth, 65.438+0.8 billion times the mass of the sun in the center of OJ287 quasar, and there is also a cloud in front of it. The greater the mass, the greater the gravity, because too much mass will collapse into a black hole. Basically, celestial bodies with 3.2 times the mass of the sun will become black holes, but even if the gravity is great, its influence range is limited. You can search "schwarzschild radius" in detail. According to the existing research and analysis, this supermassive black hole exists in the center of a spiral galaxy like the Milky Way. Of course, it is different in size, but our Milky Way still exists. This is a kind of balance. Of course, if it is too close, the matter that is basically close will basically die, just like an asteroid may hit the earth, because it is too close to please the gravity of the earth.
