Gene and cohost Tim Swartz present very prolific author Nick Redfern, who will discuss his recent book, “How Antigravity Built the Pyramids: The Mysterious Technology of Ancient Superstructures.” Throughout history, folklore, and mystery, tales have circulated of massive stones being moved through the air effortlessly by sound. Bizarre? Well, yes, it is. That doesn’t take away the fact that sound was, and still remains, the key to the construction of the pyramids of Egypt, Stonehenge, the stone figures of Easter Island, and the massive stones at Baalbek, Lebanon. Were they the work of ancient humans or of equally ancient extraterrestrials? Nick is a full-time author and journalist specializing in a wide range of unsolved mysteries.
