: Well, according to the information on the "The Starlost" fansite they have the show bible and it lists the size of the ARK to be 200 miles long with the domes being 50 miles in diameter, and it has 36 domes. Each dome is at least 2,000 square miles in area, so I don't think it makes any sense. It may just be a mistake or it might have been taken from something else.
