This is something we’re all experiencing now, that sort of weird phenomenon where it's hard to tell what day it is. The documentary explores the idea that in certain environments, time takes on an entirely different meaning. The first scene inside the habitat depicts the oceanauts returning from a dive, lighting up a smoke, and pouring themselves a large glass of wine – this was in 1963 after all. Regardless, this project did result in an amazing documentary called World Without Sun, which takes you inside the daily life of an oceanaut living 32 feet beneath the surface. Williams speaks about his time with NASA's NEEMO project here – but the idea of undersea research colonies on a larger scale didn’t quite proliferate in the way that Costeau had envisioned it. Of course, this is currently happening – Dr. Spearheaded by the famous Jacques Cousteau, the Continental Shelf Station Two project experimented with the idea of humans using an undersea living habitat as a base for ocean research.
