A. While editing a magazine story about Albert Einstein, I became interested in his long, futile search for a unified field theory, a single set of equations that could explain all the forces of nature. I began to wonder what would've happened if he'd actually discovered the equations. Einstein's theory of relativity led to the development of the atom bomb; could a unified theory pave the way for even more terrible weapons? If so, Einstein might've decided to keep the theory secret. This scenario was the inspiration for "Final Theory."
