Moon landing conspiracy theorists will tell you it was too hard to paint a realistic sky on a sound stage in 1969 so all the moon landing footage has a black sky instead. Bogus. Thanks to this article we know we had planetariums as early as 1925. The moon landing is real
NASA knew that people new that planetariums existed, so they didn't paint a realistic sky because people would think they used a planetarium. Game theory!
