The vacuum breakdown of the Lightning channel is assumed to be the origin of the super conduction of high speed lightning charge without vacuum or air resistance.
Last year, it was professor L.Dwyer who found x-ray/gamma-ray evidence inside "leaders" of lightning strokes.
See: Physorg: december 2010.
“You can see the X-ray source descending,” Joseph Dwyer, a physics professor at the Florida Institute of Technology, told a group of lightning specialists gathered Monday in San Francisco. “You start to see the air glow in X-rays.”
Dwyer took his pictures in July and August in collaboration with a team from the University of Florida at the International Centre for Lightning Research and Testing. He turned 25 of them into video clip that shows 2.5 millionths of a second in the life of one lightning strike. It is a painstaking look at an elusive subject".
Conclusion: there is a firm reason to suggest that Ball Lightning is the remnant of one of the descending micro black holes of a lightning leader, before they are evaporated!! Secondly Ball Lightning /microComets are the remnants of a fireball produced by so called Sprites at high altitude (70-100km)!
This is reason to show here the video of fireball production, inside so called Sprites always located above thunderstorms, made by the Langmuir Laboratory. (USA)
Werner Burger reported: some raindrops fell, a Thunderstorm was far away.
This fact is a strong support for the hypothesis that Sprites located at the top of heavy Thunderstorms produce Fireballs (micro black holes), which can travel over long distances and present themselves as micro Comets or Ball lightning, even far away from the Thunderstorm.
Mysterious Ice Chunks, falling from the sky, seem to be the remnants of these Micro Comets/ Ball lightnings if we adopt the principles of my Quantum FFF theory, including the new black hole paradigm.
However one of them seems to be in tact as the nucleus of a very small micro Comet, with a clear hole in the centre, showing the evaporated micro black hole location.
The possible relation between Hyperion and a Megacryometeor, as the nuclei of Comets large and small.
