    Dive into the shadows of the Cold War with host Tom McKenzie as Unexplained History uncovers the chilling reality of Project MKUltra. In this episode, we peel back the layers of the CIA’s most infamous and illegal operation: a top-secret quest for mind control.

    We also examine the massive cover-up ordered by CIA Director Richard Helms in 1973 and the lingering questions that remain today.

  • Episode 28: The Piri Reis Map - Ancient Antarctica & The Impossible Chart of 1513

    Episode 28: The Piri Reis Map - Ancient Antarctica & The Impossible Chart of 1513
    Jan 27 2026
    Join host Tom McKenzie on Unexplained History as we unroll one of the world's most baffling cartographic mysteries: the Piri Reis Map. Discovered in the dusty archives of Istanbul’s Topkapi Palace in 1929, this gazelle-skin chart drawn by an Ottoman Admiral in 1513 contains details that shouldn't exist.

    How did Piri Reis depict the coastline of South America with such accuracy just decades after Columbus? And more chillingly, does the map truly show the coast of Antarctica free of ice, centuries before the continent was officially discovered? We examine the controversial theories of Charles Hapgood, the possibility of lost ancient civilizations, and the skeptical arguments regarding historical compilation.

    Is this map a misunderstanding of geography, or evidence of a forgotten chapter in human history? Listen in to navigate the unknown.

  • Episode 27: The Baghdad Battery – Did the Ancients Discover Electricity?

    Episode 27: The Baghdad Battery – Did the Ancients Discover Electricity?
    Jan 22 2026
    In the sands outside Baghdad, archaeologists uncovered a strange object that may challenge everything we think we know about ancient technology.

    Known as the Baghdad Battery, this collection of clay jars, copper cylinders, and iron rods dates back nearly 2,000 years—and may have been capable of producing electricity long before the modern age.

    In this episode of Unexplained History, we trace the discovery of the Baghdad Battery, the scientists who tested its electrical potential, and the fierce debate over its true purpose. Could ancient civilizations have used electricity for electroplating, medicine, or ritual practices? Or is this one of history’s most misunderstood artifacts?

    We explore the Parthian Empire, experimental reconstructions, skeptical explanations, and fringe theories that suggest lost knowledge may have existed—and vanished—long before modern science.

    Was the Baghdad Battery a revolutionary ancient invention… or a coincidence shaped by modern imagination?
