Kingpins Gravity force is a product of solar activity . So comes to us free . Gravity is the main force for life .IMO scientists have absolute no idea where is the neutral point in the earth , or the strongest point . There is some spots on earth where a ball will roll upwards , instead downwards . That means when you have a free spinning wheel , if you can drop the gravitational force from one side , even by a few grams , that wheel will spin for ever , if no friction is involved .
Don't run in your garage . Is not as easy as it sounds
