Well, that’s pretty weird.
There are no so many waves filling the earth’s atmosphere (TV, AMFM radio, walkie talkies, ipods, ipads, Blackberries, cell phones, etc., etc., etc.), that maybe they are finally combining with all the natural waves that pound earth from the sun to produce their own sounds.
Sounds like the harp project people doing a lot of directed elf. They do it to control the weather, supposedly. Then again, the Russians have their own version of harp so it could be their directed elf against us. Either way who cares.
