Ball Lightning Caused By Magnetic Hallucinations

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."

      I'm not a doctor, but I predict undesirable side-effects from the interaction between your Tinfoil hat and multiple lightning strikes...

    A whole branch of my family was fathered by ball lightning! Happened back in the Great Storm of 1806. Granted, they always were the black sheep at the family reunions, but they were certainly real!

    It's clearly a bogus theory. In my experience, ball lightening is usually caused by filling it up with helium.

    Oooh yeah I'm really religiously "jumping" to conclusions. We've had DECADES to flesh this one out and the evidence is not there. The onus is on the claimant to prove the phenomenon exists, not on me to prove it doesn't. The religious ones are the ones who take flaky anecdotes and blurry photos as real evidence and reject any skepticism about their credulity as "hasty". No.

    Personal note: When I was a little kid my mother told me not to stare into the sun. So once when I was six, I did. At first the brightness was overwhelming, but I had seen that before. I kept looking, forcing myself not to blink, and then the brightness began to dissolve. My pupils shrunk to pinholes and everything came into focus and for a moment I understood. The doctors didn't know if my eyes would ever heal. I was terrified, alone in that darkness. Slowly daylight crept in through the bandages, and I could see, but something else had changed inside of me. That day I had my first headache.

    Remember, electricity follows the path of least resistance and copper in power lines provides far less resistance than does air, so perhaps it's just able to "live" longer with power lines around

    Don't anthropomorphize electricity, it makes it mad.

    a possibly fake observation hasn't been documented in incontrovertible ways after decades, therefore it does not exist. Galileo would be proud.
