Back to the drawing board. Magnetic fields is the essence that draws cosmic plasma to the center of the galaxy where stars are formed each of them in essence a magnetic field, then fusion creates the electricity, and the neutrino's, and the magnetic fields. We all agree that gravity on its own can't keep the universe or even the Milky Way together, and instead of introducing occult matter into the equation let's keep it real. Black holes is a theoretical impossibility someone smarter than me calculated, besides why would they sit in the center of the galaxy and eat the freshest baby stars of the galaxy, doesn't make sense. Indeed if true I doubt we would exist out in one of the relaxing lowradiation suburbian arms of the milky way as a 4th generation recycled star, with plentyful heavy metal!
