“Double rainbow, oh my god what does it mean?”Interesting question, although I think you are seeking a superstitious answer. Anyone have a scientific answer as to why this happens?

Future computers that modify themselves
Scientists at Northwestern University have developed a new nanomaterial that can “steer” electrical currents. The development could lead to a computer that can simply reconfigure its internal wiring to become an entirely different device, based on changing needs.
It’s a myth that most Facebook users never change their default privacy settings, said Facebook CTO Bret Taylor today. “The majority of people on Facebook have modified their privacy settings,” he said.
In reality, this assumption is probably less of a myth and more of an outdated statistic. Back in December 2009, when Facebook started more overtly mucking with its privacy defaults and options, the company stated that only 15 to 20 percent of Facebook’s 350 million users had ever modified their settings, as I reported at the time.
But today, Taylor said, Facebook’s 800 million users — especially the more active ones — are extremely savvy about their privacy settings.
