'The overview effect is a cognitive shift in awareness reported by some astronauts and cosmonauts during spaceflight, often while viewing the Earth from orbit or from the lunar surface.'
Take 19 minutes to watch The Overview Effect, a short film that explores this phenomenon through interviews with five astronauts who have experienced the "Overview Effect." The film also features insights from commentators and thinkers on the wider implications and importance of this understanding for society, and our relationship to the environment [source]. Also, keep an eye on the upcoming documentary film CONTINUUM, which was just fully funded via Kickstarter. The film about our interconnection with each other, the planet, and the universe.
