| Apr 17, 2020 at 22:21 | comment | added | Bingohank | The thought of my question was that if black holes swallow even light then 2 smbh should swallow each other and not even be able to orbit unless far apart. The fact that they can orbit but that it decays and they merge answers my question. But the effects of the jets from both smbh is still something I would like to know about. | |

| Aug 2, 2019 at 3:06 | comment | added | PM 2Ring | @Mark "Simple" calculations of the SMBH merger time result in times longer than the current age of the universe. Yet it appears that SMBH mergers have occurred, so the simple calculations aren't adequate. This is known as the final parsec problem. | |
| Aug 1, 2019 at 20:09 | comment | added | tuomas | I just added a link to one source with more details about the merger. I haven’t read through all the papers this article refers to, but they seem interesting and relevant, and might shed some more light into question about the eventual merger and its timescales | |

| Jul 31, 2019 at 22:32 | comment | added | Bingohank | Are they stable or are they destined to merge? What about their axis of rotation, are they parallel, if not, what happens where the jets collide? What are the effects in the region between the 2? | |
