Since this topic related to Julian Barbour's theories was locked, I follow up with an interesting video documentary about his theories. Documentary Noorderlight (webpage is in Dutch but the documentary is in English. By the way: why was the prior topic locked? Is Julian Barbour now considered a crackpot by the resident moderator? By the way the site also has small documentaries of 't Hooft, Smolin, Kauffman and others.
