Bubbles and Superbubbles
The Earth is enclosed in an electric/magnetic bubble extending out to the Earth-Sun L1 and L2 points
The Moon is enclosed in its own bubble inside this Earth-bubble
The Solar System is enclosed in its own bubble and in the superbubble of the galaxy.
The Lagrangian L1 and L2 define the extent of one bubble pushing into another of higher central pressure.
These bubbles are differentially spun by magnetic lines of force, and in the spin "gravity" is created.
