I read somewhere that James Cameron made the planet Pandora as scientifically plausible as possible according to his scientific advisers. Are the Na'vi's physically possible? having a humanoid structure and being like 10 feet tall and being so athletic like they were in the movie. Also, how their skeletal structure was coated in carbon fiber, it was also interesting how they could bond with the plant and animal life on the planet with their "hair". Is this all scientifically possible?
