Nikola Tesla reported rhythmic signals in 1899, Jørgen Hals recorded long-delay radio echoes in 1927, the US Navy tracked an unknown object in 1960 that turned out to be a lost Discoverer capsule, and in 1998 shuttle mission STS-88 photographed a thermal blanket that drifted away during assembly of the space station. No file connects any of these to a 13,000-year-old satellite.
The merged story claims the probe has orbited for 13,000 years, broadcasts a star map pointing to Epsilon Boötis, and that governments erase the footage. The name Black Knight came from a 1950s newspaper nickname and was never an official designation of anything.
The interesting claim is structural: the Black Knight is the clearest case of an egregore built by citation, where each new unexplained sighting retroactively joins an object that exists only as the sum of its sightings. It shows how a myth gets manufactured in real time out of genuine but unrelated documents.
If five unrelated events each get the same nickname, who named them, and why did the name stick?
