Ball Lightening Clarified
This actually works. Such a mass of heavy ions would have a natural channel to follow down to the ground generated by the lightening stroke itself and this would even draw it down and likely shape its dimensionality.
We have all naturally presumed that ball lightening consisted of a blob of electrons but that never made any sense at all. Mass confinement is certainly sufficient to allow a twenty second dwell time.
This problem has been kicking around forever and every high school physics student knows of its existence. Bravo!
Goodness, Gracious, Great Balls of Lightning!
Oct. 18, 2012 — Australian scientists have unveiled a new theory which explains the mysterious phenomenon known as ball lightning.
Sightings of balls of lightning have been made for centuries around the world -- usually the size of a grapefruit and lasting up to twenty seconds -- but no explanation of how it occurs has been universally accepted by science
Sightings of balls of lightning have been made for centuries around the world -- usually the size of a grapefruit and lasting up to twenty seconds -- but no explanation of how it occurs has been universally accepted by science. Even more mysterious are sightings of balls of lightning forming on glass and appearing in homes and in airplanes.
CSIRO scientist John Lowke has been studying ball lightning since the sixties. He's never seen it, but has spoken to eye witnesses and in a new scientific paper, he gives the first mathematical solution explaining the birth of ball lightning -- and how it can pass through glass.
Previous theories have cited microwave radiation from thunderclouds, oxidizing aerosols, nuclear energy, dark matter, antimatter, and even black holes as possible causes. Lowke disputes these theories.
He proposes ball lightning is caused when leftover ions (electric energy), which are very dense, are swept to the ground following a lightning strike. As for how they pass through glass, he says this is a result of a stream of ions accumulating on the outside of a glass window and the resulting electric field on the other side excites air molecules to form a ball discharge.
According to Lowke ball lightning is rare, but it has been witnessed in Australia many times. People just don't realize what it is when they see it.
