A new study suggests that ghostly lights like will-o'-the-wisps may be caused by microlightning, tiny electrical sparks that occur in gas-liquid interfaces, providing a scientific explanation for these mysterious phenomena and possibly even the origin of life.
The flickering blue flames known as will-o'-the-wisps, often mistaken for spirits, are caused by the ignition of methane gases in swamps, though the exact mechanism of ignition remains unknown.
Scientists have confirmed that will-o'-the-wisps are caused by tiny lightning sparks igniting methane gas in marshes, revealing a scientific explanation for this ghostly phenomenon and highlighting the role of microlightning in natural chemical processes.
