“KIC 8462582: The Plot Thickens”, is a new 17 minute video about a star hidden by unexplained debris.
Science fiction author John Michael Godier updates the theories about Tabby’s Star, 1500 light years away. It's official name includes a seven-digit phone number! Now he speculates that self-replicating robots could have mined asteroids and built an O’Neill cylinder around the entire orbit of a planet, maybe as part of a Dyson Sphere structure.
The film shows at least two O’Neill landscapes.
