Some locals ascribed the nocturnal illuminations to UFOs, while others blamed swarms of fireflies or glow-worms. Some even swore they were
caused by luminous vegetation eaten by birds.
Now a scientist has gone and spoiled all the fun, finding a perfectly rational explanation. John Pettigrew, a professor of neuroscience at Queensland
University, has discovered that the eerie lights are caused by atmospheric refraction that occurs when cold air is trapped below warmer air – when a
cool night follows a hot winter's day, for instance.
Doesnt cold air naturally sit under warm air? I would not say cold air gets trapped under warm air. Maybe he means a temperature inversion of warm air
under cold air. Hell, I could have come up with this explanation, the US Air Force has used it for 50+ years to explain alot of ufo sightings. I also
notice how conveniently car head lights and bush fires are used to explain the sightings that have been reported for thousands of years. But maybe he
is right... what the hell do I know? Although, if he had said the lights were caused by piezoelectric forces within the earth I might be more inclined
to believe his "explanation". Whatever...
