+joc Posted October 8, 2019 #2 Share Posted October 8, 2019 maybe a silly question but.... Do all galaxies have a blackhole at their center? 1 Top Link to comment Share on other sites More sharing options...

I think that's a good question joc. All spiral galaxies obviously spin around something Extremely massive at their centers...most likely a black hole? But there are other types of galaxies, including what is called an irregular Galaxy. 1 Top Link to comment Share on other sites More sharing options...

As far as we can observe it does appear that most spiral galaxies formed around supermassive blackholes.

Thank you... Which makes since because galaxies are rotating... as if they were slowly being sucked down the bathtub hole..which gives rise to another question. What eventually happens to a black hole? 1 Top Link to comment Share on other sites More sharing options...

It is thought that eventually they will evaporate due to something called Hawking radiation, but how that works is way above my paygrade so here is a link instead: https://en.wikipedia.org/wiki/Hawking_radiation 1 1 Top Link to comment Share on other sites More sharing options...

lightly Posted October 9, 2019 #8 Share Posted October 9, 2019 (edited) I wonder why spiral galaxies form a flattened Disk shape? I've probably read about it before ,but I don't remember any explanations for that . . . . . The discs are bulged in the center.... And elliptical galaxies are roundish ,rather than flat.
