Hello there, I am filming a documentary on cutting-edge physics, and I was wondering what constitutes a "professionally researched theory." What is it about ST and LQG that make them "professionally researched?" Are there other non-profesionally researched theories out there? Thanks so much! I have an undergrad degree in physics from Harvard, but I am now in film school--go figure!! I enjoyed Deja Vu--I read that Brian Greene of THE ELEGANT UNIVERSE was the leading consultant on the movie, which includes time-travel and wormholes. Speaking of which, are wormholes and time travel "professsionally researched" theories? Thanks!
