gravitation, gravitomagnetism, Milky Way, bar galaxy, evolutionary classification
The Milky Way might be a bar galaxy. In this paper, we show that bar galaxies are spiral galaxies with an orientation change of the bulge's gravitomagnetic field. The tilting of the gravitomagnetic field evolves from the bulge to the galaxy's extremities at wave speed and the physical acceleration of the stars away from the disc follow soon. Finally, this will result in a new, slightly elliptical galaxy that will again turn into a disc galaxy and then a spiral galaxy. If the Milky Way really is a bar galaxy, the solar system will some day get a novel acceleration (an apocalyptic sway?) towards a new, widely oscillating position in the galaxy. Finally, we come to a Gravitomagnetic Evolutionary Classification of Galaxies that is different from the usual classifications.
