Because the Saturn gas giants are not main attached to the star, but simply suck in so much energy with their dynamo they stay attached to the Universe, these are leach gas giants on natural formations, and artificial formations they would be used to steer and drive the Universe around like the wheels of a car, the Saturn rings reaching out into space and grabbing as they spin with their multiple rings. The rings could also be used as hands, reaching out satellites into deep space outside our Universe using slingshot velocities that swing the satellites out to grab or do something then it circles back around to the Saturn gas giant.
