I was watching a show about black holes at the centers of galaxies. And (perhaps I misheard), but there was a one line comment made to the effect that stars in a spiral galaxy don't always move around the center of a spiral galaxy in accordance with Kepler's laws (which, by that, I assume they meant, with each star carving out equal areas in equal time, i.e. closer stars go around more quickly, father stars more slowly). Instead, the stars, (if I heard right), circle at a nearly even rate regardless of distance from the center, like someone drew the galaxy's spiral on a piece of paper, and started turning the paper. 1) Is that even close to true (i.e, I misheard, or, a hard working writer that was a bit over his or her head trying to write the dialog for this subject, blew a line). 2) If that is true, how is it accounted for?
