What was that in the skies above Moscow on October 6, 2009? Some have suggested that it is a weather phenomenon known as a fallstreak hole. According to a Wikipedia article, fallstreak holes are created “when the water temperature in the clouds is below freezing but the water has not frozen yet due to the lack of ice nucleation particles. When a portion of the water does start to freeze it will set off a domino effect…causing the water vapor around it to freeze and fall to the earth as well…leaving a large, often circular, hole in the cloud.” Others, however, believe it to be a large alien spacecraft. What do you think? Let us know.
In nature, there are vortexes: the places where energy lines converge and create great havoc, including terrestrial black holes. The Bermuda Triangle is thought to be one such center of activity. But I’ve never heard of a vortex appearing in the sky.
I’d venture to say, from its mathematical precision (the circle appears perfect, like a wedding ring) that it is something not natural; something manmade. Perhaps the Russian government was testing a new aircraft?
