Earlier quoted context omitted.
something of a coincidence Orcas do go in for fads (look up 'orca salmon hats') but experts oftentimes dismiss things as coincidence because they don't have a theory and don't want to look stupid by speculating. When I was growing up reports of ball lightning were dismissed as hallucinations or optical illusions until video and spectrographic technology advanced sufficiently to capture the phenomenon: https://en.wiki…
That link says: “Owing to the lack of reproducible data, the existence of ball lightning as a distinct physical phenomenon remains unproven”
Ball lightning is one of those things that you'd expect to be easier to detect because of the increased use of cameras. Why isn't Youtube flooded with dozens of videos showing lightning balls? There are a few, but none of them are convincing. (One is clearly a drone being flown in a thunderstorm.) Most are fakumentaries. (3 seconds of shaky zoomed-in "proof" and 5 minutes of a so-called expert breathlessly talking about it.) How can ball lightning both have lots of people claiming to see it, but is infrequently caught on video?
My suspicion is people are encountering normal lightning discharges at close range and the "ball" is an illusion caused by how eyes work. If someone attempted to get ball lightning on camera they'd be disappointed to see the recording look nothing like how they remembered it.
