When she was talking about the 3 different structures she believes are most efficient, when she said a ring I immediately thought of the Halo franchise. In the game the covenant builds 7 ring worlds that wiped out all sentient life within 3 radii of the site. The game is also set in 2531 so thats so fricken neato. This was a great episode!!!,(reply>), Same here! Can’t wait to see the halo ring in the new tv series. 🤘
