  • A video supposedly showing a rare, natural phenomenon known as a gobular bolt, or ball lightning, went viral in January 2020 with a posting on the Facebook page Cambio Digital that quickly racked up more than 4 million views: This video was frequently circulated with the caption: This is a globular bolt, better known as scintillation. They are tremendously rare and peculiar. This video, however, does not show a globular bolt, a scintillation, ball lightning, or sphere lightning. The video actually features a computer generated image. The video was created by Andrei Trukhonovets. It was posted to his YouTube page back in May 2019, along with a note stating that the footage featured CGI. Trukhonovets also responded to a number of comments and bemoaned the fact that this video was circulating as if it showed a genuine ball of lightning: Here's the original video created by Andrei Trukhonovets. This footage was also shared to Trukhonovets' Instagram page along with the tags #vfx #aftereffects #lightning #cgi #oc. https://www.youtube.com/watch?v=IwR14D3NA8c&feature=youtu.be While this video clearly doesn't show an actual globular bolt, scientists have been investigating the phenomenon, sometimes referred to as sphere lightning, for more than a century. In 1901, an illustration of l'eclair en boule, or a ball of lightning, appeared in the French science book La nature: revue des sciences et de leurs applications aux arts et à l'industrie (Nature: review of sciences and their applications to arts and industry), where it was described as one of the most curious manifestations of electricity. Numerous reports of ball lightning over the last century exist, but scientists have not completely wrapped their heads around this bizarre, natural phenomena. One theory, offered in the July 2019 issue of the journal Optik, holds that ball lightning is actually light trapped inside a thin bubble of air: EarthSky.org writes: In short, whatever ball lightning is, it is not depicted in this viral video.
