"content": "Black holes in general tend to rotate very fast, as they try to conserve angular momentum while shrinking in size.\n\nThe supermassive black hole at the center of our galaxy Sgr A* (4.3 million solar masses!) is spinning with an angular velocity that is ~60% of the max possible value, and with an angular momentum of ~90% of the max possible value.\n\nSgr A*'s spin causes the spacetime around it to be squashed down to the shape of a football.\n\nhttps://www.nasa.gov/image-article/telescopes-show-the-milky-ways-black-hole-is-ready-for-a-kick/\n#quasar #Chandra\n5/n\nhttps://cdn.fosstodon.org/media_attachments/files/112/750/731/445/066/125/original/7923697929268fac.webp\n",
