In Quantum FFF Theory, Lightning bolts are made of a splitting Quantum knot of real rigid quantum strings, forming (Micro) Black Hole nuclei.
They EAT and evaporate into the vacuum lattice (Axion Higgs Field) and leave a temporary superconducting channel behind, E.g. for fast lightning charge transmission.

These Quantum knots can have all sizes, from the Big Bang exploding nucleus, to supernova black holes down to Lightning knots.
