Investigative mythologist, William Henry returned to the show to share cosmic theories related to earth changes and human evolution. He discussed the notion of a "galactic superwave," Dr. Paul LaViolette's term for an intense volley of cosmic rays that comes from the center of our galaxy. This occurs around every 13,000 years, Henry said, sending out electromagnetic pulses and a gravity wave which could trigger tsunamis and cataclysmic events on our planet. This might have been what happened to Atlantis, he suggested.

Through his analysis of ancient artworks and artifacts, Henry postulated that some civilizations were aware of this galactic superwave. He cited the design on pottery made in Crete as an example. The Egyptians were aware of cosmic activity also, he said, and he interpreted a depiction of King Tut, as showing him being anointed with a manna-like material "milled" from galactic emissions. A similar transformative substance, called ITZ was described by the Mayans as a "cosmic sap," he added. View William's related images.

Planes & Lasers

First half-hour guest, optics consultant Michael Fulton discussed recent laser incidents affecting commercial pilots. He suggested that film coatings embedded in either a plane's windows or spectacles/contact lenses worn by pilots could offer protection from the distracting and blinding properties of lasers.
