13,000-Year-Old Alien Satellite? Unraveling the Black Knight Conspiracy Theory
The Black Knight legend links Nikola Tesla’s 1899 reports of periodic radio signals from Colorado Springs to the idea of an ancient satellite in Earth orbit. In 1927 Jørgen Hals observed long-delayed echoes, and in 1973 Duncan Lunan claimed a star map pointing to Epsilon Boötes suggesting a 13,000-year-old alien probe, later retracting parts of the interpretation. In 1954 Donald Keyhoe asserted the Air Force had detected two unknown satellites, a claim with little evidence and likely a publicity stunt. In February 1960 the U.S. military detected an unidentified dark object in polar orbit, later identified as Discoverer 8 debris
