Ganymede Hypothesis
Gravity is by 40 orders of magnitude the weakest force in nature. Asking gravity to form up a solar system from swirling dust or to hold a spiral galaxy together is like asking the littlest kid in the school to do the powerlifting event. What actually creates solar systems are cosmic Birkeland currents createed by plasma charge separations in space and the electromagnetic pinches where the current pairs of such a thing cross each other. Those pinches DO have the power to aglommerate the plasma of space into stars. Birkeland currrents with stars or protostars showing at their pinch points are called Herbig/Haro objects. HH objects are not gaseous "jets" as some sources claim; a gas jet would dissipate in seconds in the near vacuum of space.
The Ganymede Hypothesis is a theory of human and solar system origins based on the idea of our own solar system having originally formed as such a Herbig/Haro string.
