well, according to one physicist in 'What the bleep do we know?', levitating the Pentagon would be physically possible, as is walking on water. According to him and a few others from the movie/documentary, positive and negative thoughts are proven to have a physical effect on the world around us. He says, theoretically, that if you were to actually believe that you can walk on water, then you'll walk on water. The only problem is, if you try and believe something like that, the one thread of positive thought will only be covering up the innumberable threads of negative thought. So until somebody can control every aspect of their brain, conscious and subconscious, nobody is going to levitate the pentagon. im stoned
