A professor at Montana Tech has suggested the UFO phenomenon may be evidence of time travel. In his new book, Identified Flying Objects, anthropology professor Michael P. Masters argues UFOs are time machines occupied by humans from the future. "The phenomenon may be our own distant descendants coming back through time to study us in their own evolutionary past," he said. As evidence, Masters (who will be our guest on the Thursday 3/28 show) notes abductees often describe their encounters with entities who appear human-like.
