The impression I got was that this is a long straight thing that is spinning. “14 nearby galaxies rich in hydrogen gas, arranged in a thin, stretched-out line about 5.5 million light-years long and 117,000 light-years wide.”
You don’t have to think about that very long to see something strange. A line spinning around a common point must go slower in the middle and faster on the ends, just to keep up and even be a line of things.
If the whole line maintains a uniform speed, the middle will complete a rotation much faster than the edges, and what was a line shortly becomes a spiral.
Or, that’s the way shit is supposed to work. Unless you’re a galaxy. And in that case, people make shit up to explain your non-Netwonian dynamics. There isn’t enough info in the article to understand if they are implying a vast halo of dark matter to support this rotating structure. Christ. Something that big, spinning, with lobes, would send out gravity waves. The whole set of ideas here is just a fraught mess.








Well, it was an interesting article, and I agree with all their points. I’m not sure what I expected. The article was a bit more wide-ranging than just a list of facts. Yes, it did predictably start off with climate denialism, but it went other directions too. Worth a read.
Edit … Heh. I’ve rescanned it a few times. I love the way the guy shits on AI on the way out the door. Good work.
More edit … um … this guy’s a freeeak. Love it. He’s got a podcast called Starts With A Bang. He looks like Dr. Robotnik.
