Call it magic, call it destiny, but the size and weight of the moon allows the disc to fit exactly in place to block the sun periodically. Only the flaming corona can be seen during the total eclipse.
The corona on the outside of the sun contains the higher frequencies of energy. Physicists call that the “skin” effect. Compare it to a current moving through a copper wire; higher frequencies travel mainly on the wires’s surface.
Magnetism – current – the moon as a transormer of the sun’s rays. Evolution occurs at the edge, leading or cutting. The moon interrupts the normal flow of energy in a measure of time. The moon is essentially creating an alternating current at a high frequency.
