In 1967, he went to United States to study General Relativity theory at "Central Studies of Gravitation" at Syracuse University under direction of Peter Bergmann and Joshua N. Goldberg whom were among the authoritative experts in general relativity after the inventor, Albert Einstein. Here, Pantur went furthermore studied one of the hottest topics in physics at the time which tried to unify quantum field and general relativity to find quantum gravity theory. It is one of Einstein's dream which had tried but failed to formalize the fourth interaction in the universe into one single theory called Grand Unified Theory.
