Supermassive black holes found spiraling in at seven percent light speed

Recent HN thread on a NY Times article talking about the same work: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10233874" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10233874</a><p>That thread also contains an excellent description of the last parsec problem by HN poster antognini.

&gt; Supermassive black holes are expected to come in pairs pretty often. That’s because every galaxy has its own supermassive black hole, and galaxies often merge, bringing the two together.<p>Okay, but following this reasoning, we should also see triples and quadruples, I would say.

Hmm, I wonder what it would be like to fall into a black hole rotating at light speed then? In addition to the spaghetti effect, would it be a whorled spaghetti effect? What would it be like to fall in from the top versus the equator or another latitude? I wonder what the singularity at the center would be like besides just a hoop. Can you make the singular hoop (english sure is strange here) process if there is another large black hole nearby?<p>Man, I need more or less coffee, I can&#x27;t tell which though.

What would happen mathematically if two singularities orbiting each other merged? Would it become one singularity or some super nasty complex mathematical system?

Don&#x27;t really &quot;weird&quot; things start to happen when physical matter hits 10% speed of light?

&quot;The Final Parsec Problem&quot; -- not to be confused with the Last Mile Problem :p
