2001 Isaac Asimov Memorial Debate: The Theory of Everything

Tuesday, February 13, 2001

Can the entire Universe be explained with a single, unifying theory? This is perhaps the most fundamental question in all of science, and it may also be the most controversial. Albert Einstein was one of the first people to envision a unified field theory that might describe the behavior of all matter and energy in the cosmos with a single stroke of the pen; however, a definitive solution has eluded physicists to this day. As we enter the twenty-first century, the leading candidate for a theory of everything appears to be string theory, which considers every particle in the Universe as a multi-dimensional entity—a string—that manifests itself in our Universe differently depending on how it twists and vibrates.
