What is ball lightning and what is the science behind it?
AlchemistK said:that didnt help! What IS ball lightning?
Professional physicists have, in just the last three decades, proposed everything from ball lightning being an ionized gas, some weird electric dipole to explaining the ball lightning as the disturbance caused by the passage of a microscopic, transient black hole.AlchemistK said:that didnt help!

There are professional physicists that are proposing black holes as an explanation??arildno said:Professional physicists have, in just the last three decades, proposed everything from ball lightning being an ionized gas, some weird electric dipole to explaining the ball lightning as the disturbance caused by the passage of a microscopic, transient black hole.
Most definitely.DaveC426913 said:There are professional physicists that are proposing black holes as an explanation??
Danger said:Maybe the Druids were right... it's pixies.
pallidin said:Interesting. Seems that ball lightning is a true unexplained phenomenon.
AlchemistK said:Is it something caused only during storms? Can't it be that the huge current doesn't have a single low resistance path so it kind of diffuses as a sphere?
A Brazilian team has managed to make similar spheres of light in the lab, while getting them to bounce around for several seconds.
AlchemistK said:Well if what is written there is true,I guess the mystery is solved.
But isn't it weird that all the other well known websites claim the reason to be unknown?
phrak said:the quantum domain, especially the coherent part of it, produces plenty of some nonintuitive results on human scales. Could ball lightning be a naturally occurring laser.
jarednjames said:Well it doesn't say that is ball lightning, just that they produced something similar. It is only the article title that say's they've done it, the actual claims within the text aren't so.
An artificially induced image in the brain is called a "phosphene". Kendl adds:
“An observer located within few hundred metres of a long lightning stroke may experience a magnetic phosphene in the shape of a luminous spot."
The physicist says that this is much the simplest and likeliest explanation for ball lightning.
jarednjames said:Or it simply doesn't exist at all:

AlchemistK said:And phosphenes can be caught on cameras and then effect other human minds?
jarednjames said:Hey, I'm just giving you explanations.
Do we have verified video / photo evidence of ball lightning?
Do we know people see the same thing or their own version of it (multiple people experiencing the effects and then the 'group effect' - i forget the name of it - that leads to all persons reporting similar events).
Danger said:In a way, this is reminiscent of a very well-known documented phenomenon from the early days of telegraphy. Iron particles from the smoke of coal-fired steam locomotives used to get caught up in the magnetic fields surrounding telegraph lines (which always paralleled the tracks) and end up as glowing "doughnuts" strung along the wires like beads.
While I've never seen anything to suggest that particulate matter is involved in ball-lightning, I can't help wondering whether or not there is a correlation.

Ball lightning is a rare and unexplained phenomenon that appears as a glowing sphere of light, typically ranging from the size of a pea to a few meters in diameter. It is often associated with thunderstorms and can last for several seconds to minutes before disappearing.
The exact formation mechanism of ball lightning is still unknown, but it is believed to be caused by a combination of factors such as electrical discharges, plasma physics, and atmospheric conditions. Some theories suggest that it may involve the ionization of air molecules, while others propose that it could be a form of self-sustaining plasma vortex.
There have been reports of ball lightning causing damage to objects and even injuring people, but these cases are rare. Overall, ball lightning is not considered to be a significant threat to human safety as it tends to dissipate quickly and does not possess the same destructive power as lightning strikes.
Scientists have been able to produce ball lightning-like phenomena in controlled laboratory experiments, but these are not exact replicas of the natural phenomenon. The conditions and mechanisms involved in the formation of ball lightning in nature are still not fully understood, making it difficult to replicate in a controlled environment.
There are various theories and ongoing research on ball lightning, including its formation, properties, and potential applications. Some scientists are exploring the possibility of using ball lightning as a new source of clean energy, while others are investigating its potential connection to other natural phenomena such as sprites and elves.
