Frequently Asked Questions
Anecdotal reports suggest it can be, capable of causing burns, damage to property, and even fatalities, though it typically vanishes harmlessly.
While thousands of credible sightings exist, reproducible laboratory creation of long-lasting, macroscopic balls matching all descriptions remains elusive, placing it at the frontier of atmospheric physics.
Ball lightning is associated with thunderstorms and is a luminous sphere of light. Will-o'-the-wisp is a faint, flickering light often reported over marshes, historically attributed to gases, and not directly linked to storms.
Yes, many reports describe it passing through windows, walls, or even appearing inside aircraft cockpits, adding to its mysterious nature.
