TLC/DISC during one of my bouts with insomnia. I will look up a cite on the net and post when I have time.
Consider the possibility that the show you saw was one of those Erich Von Daniken Chariots of the Gods shows, or Arthur C. Clarke’s show about the paranormal. I’m aware that there are folks who think that Central and South American carvings portray things like haloes, astronauts, etc., but what I wanted was a cite from an actual archaeologist, or something like that.
Actually, I’ve long suspcted that halos were used as symbols of the holy y several grous independently. There are a lot of optical phenomena that produce halo-like emanations around one’s head. The most imressive is the Glory, which produces multicolored rainbow-like circles around the shadow of your head. It used to b that you could onl see this when looking doen on your shadow on a cloudbank when you were top a mountain (One example is “The Spectre of the BRocken” - see M. Minnaert’s book The Nture of Light and Color in h Open Air). But since air travel became affordable for everyone, ou ca see it around the shadow of your plane on the clouds below. I always look for it when I fly. Then th4re’s Hligenschein, in which you see a bright halo around your shadow’s head in dewy grass. And there’s a somewhat similar effect you see with your shadow in muddy water. There are other effects as well. Suffice it to say that it would be hard for people to miss opportnities or seeing enhanced light scattering around the hads o their own shadows in a variety of circumstances. And it’s always round one’s own shadow – not companions. So you always seem to be something special. Artists would pck up on that. (Minnaert pointed out that, when you photograph on of these, the halo is centered on the camera in the photo.)
No EM fields or auras needed.
