Ball Lightning is an unstable Magnetic Interference String Knot.

.

Quantum Function Follows Form Theory says:

1: Black Holes ( even ball lightning) are knots of primary substance strings, compressed by the Casimir oscillating vacuum and dilute it by absorbing the vacuum.

2: BHs create and reject all propeller shaped Fermions at their horizon by the local concentration of the opposing  oscillating vacuum particles, like in the LHCollider. see also: https://vixra.org/author/leo_vuyk
