Spinning Black Holes

On understanding the origins of

If supermassive

holes

increased in size primarily by feeding on a constant flow of matter from within their own galaxy, their rapid rotation would be expected to be very large because the angular momentum of this matter would be more or less aligned, so it would accumulate over time, but instead, if supermassive black holes propagate mainly by merging with other massive black holes, they could be expected to have lower rotation speeds because the rapid rotation of two holes blacks would probably be randomly oriented. that aligned because We are able to measure the rapid rotation of more black holes in different ways further away and therefore further back in time, we should be able to better understand their growth, and since supermassive black holes are located in the centers of most galaxies, they are also at the center of our understanding of how these galaxies formed and gradually evolved over billions of years.
