A space researcher has offered what he believes is the correct solution to a mystery that's been flying around cyberspace for the past week: A strange tangle of white lines in China's Gobi desert discovered in Google Map images. Military pundits, armchair investigators, and conspiracy theorists have had a field day with the strange set of lines.
It's a UFO landing strip!
It's a mockup of the streets of Washington, D.C., constructed for nefarious military purposes!
It's a top-secret military installation doing experiments in controlling the weather!
It's a nuclear testing range!
It's a hoax: the Google Map images themselves are fakes, and the lines are not actually there!
A previous Discovery News piece concluded that it probably had some military connection (such as target practice range, based in part on the fact that other similar sites in the area had airplanes sitting in them), and now a NASA scientist thinks he's got it figured out.
