An old but real ball lightning video exploding after train crossing and showing overload of negative charge decharging to metal poles and rails.

The negative charge of each ball lightning or Black Hole, can only be explained by the Q-FFF Theory.

see:

Examples : Ball Lightning going into the local wind sirection , by its self produced plasma tail rotating backwards and able to push the BJ into the wins ( for Nebula Hotspots : agianst the stellar radiation , or even against the local Axion vacuum grvity wind.

See; String Knot Black Hole Black Hole Splitting Big Bang.

Also: the Black Hole is described as a Bose Einstein Composite of photons compressed together by the gravitating Oscillating Axion vacuum.
