Okay, here’s what I’m thinking: - Take a newly-forming planet as Earth was at one point and give it a metal-rich core that is spinning from the momentum of the formation process; - As the crust and upper mantle begin to solidify, the metal-rich core continues spinning unabated within a blanket of liquid magma; - [...]

Quantum energy inside all element atoms. One basic energy source that creates different reactions, products, bi products, and fields when played upon different matter. Or substances. Like magnetic fields or ferromagnetic fields. I look at this basic idea played upon earth and it’s magnetic belts. Like the shifting poles and changes in earths magnetic field. [...]
