From: HVAC on 20 May 2010 06:55 Ball lightning is a rare circular light phenomenon occurring during thunderstorms. Scientists have been puzzled by the nature of these apparent fire balls for a long time. Now physicists at the University of Innsbruck have calculated that the magnetic field of long lightning strokes may produce the image of luminous shapes, also known as phosphenes, in the brain. This finding may offer an explanation for many ball lightning observations. Physicists Josef Peer and Alexander Kendl from the University of Innsbruck have studied electromagnetic fields of different types of lightning strokes occurring during thunderstorms. Their calculations suggest that the magnetic fields of a specific class of long lasting repetitive lightning discharges show the same properties as transcranial magnetic stimulation (TMS), a technique commonly used in clinical and psychiatric practice to stimulate neural activity in the human brain. Time varying and sufficiently strong magnetic fields induce electrical fields in the brain, specifically, in neurons of the visual cortex, which may invoke phosphenes. "In the clinical application of TMS, luminous and apparently real visual perceptions in varying shapes and colors within the visual field of the patients and test persons are reported and well examined," says Alexander Kendl. The Innsbruck physicists have now calculated that a near lightning stroke of long lasting thunderbolts may also generate these luminous visions, which are likely to appear as ball lightning. Is the mystery of ball lightning solved now? Ball lightnings are rather rare events. The majority of researchers agree that different phenomena are likely to be summarized under the collective term "ball lightning." Over time, various theories and propositions about the nature of these experiences have been suggested. Other researchers have produced luminous fire balls in the laboratory, which appeared not completely unlike ball lightning and could explain some of the observations but were mostly too short lived. Other plausible explanations for some of observations are St. Elmo's fire, luminous dust balls or small molten balls of metal. In which cases then, can a lightning bolt invoke a ball-shaped phosphene? " Lightning strokes with repetitive discharges producing stimulating magnetic fields over a period of a few seconds are rather rare and only occur in about one in one hundred events," reports physicist Kendl. "An observer located within few hundred metres of a long lightning stroke may experience a magnetic phosphene in the shape of a luminous spot." Also other sensations, such as noises or smells, may be induced. Since the term "ball lightning" is well known from media reports, observers are likely to classify lightning phosphenes as such. Alexander Kendl's hypothesis that in fact the majority of ball lightning observations are phosphenes is strongly supported by its simplicity: "Contrary to other theories describing floating fire balls, no new and other suppositions are necessary."

Never saw a picture of ball lighning Hmmm Its said to be a plasma gas ball. Hmmm Live in the most lighning area on Earth,and nothing has been on ball lighning in many years. Maybe it relates to aliens,and Presley. Ghost,Gods and devils TreBert

I have seen a ball-lightning, and it was hanging in from of my open window for many seconds before exploding on the radio antenna between two trees downstairs, Just a ball, maybe 30 cm diameter, no heat radiation, no sound, and enough power to evaporate that antenna a few seconds later with a bang, VERY physical. I personally think ball-lightning could be an electron black hole. There are movies on youtube showing these balls floating in air, somebody should look at those. Camers have no BRAINS. An other bunch of nutcase researchers who do have no clue, and other paper for the round bin, time and money wasted, and other clueless PhD is born. Dinosaurs, humanity will go dinosaur's way that way. Bet nobody of them so called 'researchers' ever SAW one themselves.

The lightning stroke produces a magnetic pulse which in turn triggers neurons in the brain, which fire producing apparent spots before the eyes? Sorry, but that doesn't work. There would be no relationship, by this theory, between the position of the ball lightning and the path traversed by the lightning stroke. The "ball lighting," by this theory, is in the mind, not in the world. However, many reports of ball lightning do not fit that scenario. For example, one day many years ago I was driving while a storm was approaching. I was on a road near the edge of a cliff, which dropped off for about 30 feet, almost straight down, near the edge of the road to my right, to a flat field with grass and some widely scattered oak trees, one of which was very large. As it happened, I was looking at that tree, which was about 100 feet away, when it was struck by lightning. A bolt struck the tree and then, as it dissipated, it broke into thousands of glowing balls, each roughly the size of a basketball, which then disappeared. If the balls were a magnetically induced hallucination and existed solely in my brain, why did their positions perfectly line up with the path of the lightning bolt, which unarguably existed in the real world? Bottom line: lightning is real, and ball lightning is also real. --Mitchell Jones}*** ***************************************************************** If I seem to be ignoring you, consider the possibility that you are in my killfile. --MJ

And we all saw exactly the same thing, and heard the same strange crackling/hissing noise. I can not explain it to this day, nor do I even try, but just accept that it exists. |
