| Nov 29, 2014 at 1:48 | comment | added | Yashank Dixit | Ya that seems to be more possible than the star theory | |
| Nov 28, 2014 at 14:51 | comment | added | HDE 226868 | The gas cloud idea is interesting. I think it's more probable than the star idea because massive gas clouds may not need a lot of accretion to grow so large. | |
| Nov 28, 2014 at 2:15 | comment | added | Yashank Dixit | It may be because of star but the one interesting theory here is the collapsing of massive gas clouds and is more impressive as believed by some scientist.Don't yo think so? | |
| Nov 27, 2014 at 7:27 | comment | added | ProfRob | @KyleKanos Another possible solution: The collapse of very massive ($10^5 M_\odot$) stars unto seed black holes, which then merge and accrete material over billions of years. Perhaps. | |
| Nov 27, 2014 at 2:16 | comment | added | Kyle Kanos | @RobJeffries: You are correct, it is only part of the solution. The other part is a billion years worth of accretion (the authors neglect mergers in their study). Following the links sometimes helps ;) | |

| Nov 26, 2014 at 22:01 | comment | added | HDE 226868 | @RobJeffries Yes, it would only be the beginnings of a solution. Both the universetoday article and the paper Kyle Kanos cited say that these stars would only be the "seeds" of a supermassive black hole. | |
| Nov 26, 2014 at 21:58 | comment | added | ProfRob | How does the collapse of a $10^{5}M_{\odot}$ star make a supermassive black hole? This could only be part of a solution right? Supermassive blackholes are 10-10,000 times more massive than this. | |
| Nov 26, 2014 at 19:20 | comment | added | HDE 226868 | @KyleKanos I hadn't seen that paper, but that was what I was trying to get at with the last bullet. | |
| Nov 26, 2014 at 15:09 | comment | added | Kyle Kanos | Another possible explanation: collapse of $\sim10^5$ solar mass star. | |

| Nov 26, 2014 at 14:56 | comment | added | HDE 226868 | @ChrisWhite Okay, I'll add something to that effect. | |
| Nov 26, 2014 at 14:55 | comment | added | user10851 | I'd add that we can adjust parameters for various models for the growth and mergers of these black holes, and this can lead to either underpredicting or overpredicting their abundance. So it's not a situation of "we can't explain where they come from" but rather "there are many ideas that work, we're not sure which most accurately depicts reality." | |
