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.

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.

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.
