Huh? So what would happen or what would be the effects on a galaxy if say a Supermassive black hole eventually vaporized in the center of the Milky Way? I understand stars would no longer disappear etc. but would the galaxy be any different?
The Galaxy would in theory would loose its one unifying component - These Supermassive Black holes act as gravity wells for solar systems. Though I'm sceptacle regardless. What they're talking about is mini 'big bang' effects where the point of the black hole just doesn't hold together anymore and vaporizes.
If we're just talking abut Black Holes just loosing mass over time, one that holds a Galaxy together like the Milky Way, in theory, the milk way would potentially drift apart. I'm not really sure how a black hole would loose mass, especially one that feeds off a Galaxy.

I read somewhere that Super massive black holes tend to eject energy out. Maybe that's why? But if our black hole were to cease to exist, the Milky Way would cease to exist. The stars and solar systems would just drift, without a dense body forcing them towards the center, inertia would just spread everything out.

Well, that's for smaller black holes. I believe larger black holes need less energy to sustain themselves.

i agree wit fragkrag if SBH disappear then nothing will hold MWG together so it wud just be spread apart

Einstein proved that gravity changes travel just as fast as light and are not instantaneous so unless the blackhole vaporized a long time ago we don't have anything to worry about in our lifetime.

large black holes emit radiation, x-rays and other shit. In billions ------- of years, the only thing that will exist in this universe will be black holes because everything is expanding and the density of the universe will be so dispersed. And after some more time, those Black holes too will disappear.
check out a documentary called time.
its a 4 part series, you can find it on torrents.

Considering the universe is estimated to only be about 14 billion years old. By the time billions of billions of years have passed there wouldn't be any galaxies in the conventional sense left anyway so the question is pretty much irrelevent. All the stars would have decayed by then.

I understand stars would no longer disappear etc. but would the galaxy be any different? yes... because the galaxy would lose the thing basically holding it together... i wouldn't be able to predict what could happen, but bad shit may happen really fast or nothing noticeable might happen, to us in our own lives.
