"The results of our study support the idea that galaxy magnetic fields are generated by a rotating dynamo effect, similar to the process that produces the Sun's magnetic field," Mao said.
Pincho says... We live in a Gravitational Universe which creates magnetism, and the rotating dynamo effect is to contain gravity at a point, because spin is local to an area. When gravity is all moving towards a point it builds the Universe...
So magnetic outflows have been in my theory for over ten years now...
So overall you have a galaxy forming from gravitational umbilical cords in a transparent backdrop to create opacity from rotating magnetic tubes of light. The outflow expands the Universe secondary to the creation of the universe.
