Recently published findings on Milky Way’s barred central bulge bring more credibility to our evaluation of the bulge as the galaxy’s proton dump. Peer review can’t confirm that for us because even our betters are still on the wrong track and are unlikely to come off it anytime soon. Come to find out, only two spiral arms predominate. They connect to the central bar that spans Milky Way’s expanding central bulge. (http://www.newscientist.com/article/dn7854--bar-at-milky-ways-heart-revealed.html)
The spheroidal bulge that contains protons held aloft from the galactic center by combination of orbital velocity and electrostatic repulsion must inherently be traveling at lesser tangential velocities than star field matter confronted at its immediate upper strata. (Material above would require greater velocity to hold equivalent altitude without the protons’ electrostatic boost.) Thus, the encroaching bulge was a growing proton bag of some 27,000 light years’ diameter, just about 270 centuries ago. (The estimated length of the central bar that was halfway here at the time.)
Introduction of stellar system material from both major spiral arms into the proton atmosphere through which it must travel throws braking resistance against influx velocity with consequential heating of the enveloping proton atmosphere to incandescence. Any material attached to neutrons, a planet or helium atom for instance, turns downward, guiding into a totally vertical drop toward the event horizon. Protons stripped from simple hydrogen join the galactic bulge itself. The bulge should extend its radius as protons whipped ahead by captured matter rise into higher orbits. Kinetic energy transfers into heat in all of this commotion, and perhaps some distributed fusion dubs in a little more glow as galactic matter marches down to the super-massive black hole below. As a matter of fact, dismantled stars don't chill out any too quickly.
The bulge may well have become too portly to ever perform again as a disk for polar jetting. Milky Way would more likely be harboring an electron bath around her black hole. Our polar jetting tale should hold up well enough for much younger galaxies, and there are hints that second childhood can overtake an older one.
