Ball Lightning Caused By Magnetic Hallucinations 269
KentuckyFC writes "Transcranial magnetic stimulation involves placing a human in a rapidly changing magnetic field powerful enough to induce eddy currents in the brain. Focus the field in the visual cortex, for example, and the induced eddys cause the subject to 'see' lights that appear as discs and lines. Move the field within the cortex and the subject sees the lights move too. Physicists have calculated that the fields associated with certain kinds of multiple lightning strikes are powerful enough to induce the same kind of visual hallucinations in anybody unlucky enough to be within 200 meters or so. These fields ought to induce hallucinations that would take the form of luminous lines and balls that float in front of the subject's eyes, an effect that would explain observations otherwise classed as ball lightning, say the scientists."

Look, I'm sorry to piss on everybody's parade, but its time to relegate ball lightning to its rightful place in history alongside phrenology and N-rays [wikipedia.org]. The invention of the CCD and the associated UNBELIEVABLE proliferation of personal digital imaging devices over the past decade means that virtually everyone has a camera in their pocket at all times now. If the phenomenon of ball lightning existed at all, we should be seeing like one multiply reported HIGHLY CONVINCING video a week uploaded to the internet showing this. In fact, the number of ball lightning sightings and recordings over the past who knows how many years has pretty much stayed constant. If ball lightning exists at all, it's in the heads of observers, either as a result of a terrified mi-d thunderstorm hallucination or a result of some magnetic field induced phosphene as reported in this new paper.
If ball lightning were an actual physical phenomenon, the number of video observations of it should have skyrocketed over the past 10 years along with the availability of personal digital imaging devices in the same way that once Red Sprites and Blue Jets were first reliably observed with very high speed video in 1994, observational replication around the world was practically IMMEDIATE [youtube.com] and widespread.

Not so fast, what do most people do when a severe storm blows in? They put their camera away and run for shelter. Unlike Sprites and Jets, ball lightning is typically small and often seen close to the ground such that you won't capture anything useful from miles away.
Most of those digital cameras out there are in the possession of people who have no idea how to take a well focused non-blurry and non-shaky picture or video with them in even the best conditions. In addition, they're mostly cheap cellphone cameras with barely adequate lenses that are just about good enough to take a few snapshots while out with friends. The odds that they would get a decent picture of a light source that isn't just a big blur and doesn't look like a reflection from the lens are nearly nil.
The key to getting good images of sprites was to figure out a few places where they were nearly sure to be seen and to get ready in advance with high end cameras fixed to good solid tripods. A bunch of amateurs with their disposable Kodak cameras and cellphones still won't likely photograph a blue jet.
There are several easily reproducible phenomena that might be what people are describing or it might be something else (even magnetically induced eddy currents in the visual cortex).
There is actually little doubt that ball lightning is a real phenomenon. There is a great deal of doubt as to what it is. There are a number of crackpot theories that are almost certainly wrong. There are a few good theories that might be correct. It's hard to gather enough evidence to say which is better since we haven't narrowed down where one should go and under what conditions to reliably see any. It's down to sheer luck.

If these are equivalent to migraine auras, I'm very skeptical that they can explain ball lightning. I've periodically experienced migraines and what doctors assure me is an aura preceding it. I don't know about others' subjective experience with auras, but while it's an annoying visual artifact covering some or all of my visual field, at no point did I ever perceive it as some localized 'ball' with anything like a defined position, distance relative to me, etc. as ball lightning is often described. It was always something I perceived as an internal static that makes my vision mostly useless, not some external object.
Again, there could just be subjective difference, but I've never heard a fellow migraine sufferer describe an aura as some ball of light.
For those that suffer from migraines, these lights and balls should be familiar as "aura", or scintilating scotoma. For migraineurs, these lights last longer because they are caused by changing bloodflow to the occipital lobe over a longer period of time. It most assuredly activates the same neurons that this magnetic stimulation of neurons produces.

Actually, this ability to be "tracked" is common in color/light optical hallucinations that are produced in the "front end" of your brain's visual processing, as opposed to more life-like and realistic (i.e. a deceased relative) visual hallucinations that occur father down the image-processing pipeline.
