Oppenheimer assembles a team consisting of Rabi, Hans Bethe, and Edward Teller, and collaborates with the scientists Enrico Fermi, Leo Szilard, and David L. Hill at the University of Chicago. Teller's calculations reveal an atomic detonation could destroy the world. After consulting with Albert Einstein, and having Bethe do his own calculations on the matter, Oppenheimer concludes the chances are "near zero". Teller attempts to leave the project after his proposal to construct a hydrogen bomb is rejected, but Oppenheimer convinces him to stay.
