Not my >department, Michael. You ask useless questions Nope. Huge difference. Once you get something rotating, it will continue to rotate with the same rate forever, barring friction/external forces, and as long as something (gravity) holds it together. Angular momentum is a conserved quantity. On the other hand, retarded precession requires a continuous EXTERNAL torque which is constantly changing the angular momentum. Again, angular momentum is a conserved quantity but is constantly changing now, so it has to come from/go SOMEWHERE. Where? And how? You have no answer for that, and otherwise it violates conservation of angular momentum. And energy. Plus your retarded precession solves NOTHING. Other than the demand for your OCD to be fed. No open questions of physics answered, no nothing. Rotation, yes, it plus gravity keeps galaxies together without collapsing into a black hole or something. Precession: Nada. And, you avoided the question of how can something that doesn't even rotate at a fixed constant rate. like a galaxy, possibly precess in a 1:2 ratio, when the inner parts completes more revolutions than the outer parts during the same time? That's because you can't answer that! Every single star in the galaxy orbits INDEPENDENLY. What is the rotation rate of a hurricane in revolutions per hour? There is no answer because the inner part (just outside the eye) has the fastest winds and the shortest distance to complete one revolution, while the outer parts have slower winds and have much further to go for one revolution. Spiral galaxies are much the same.
