The One with the hutt

A theory of everything (TOE) is a hypothetical framework explaining all known physical phenomena in the universe. Researchers have searched for such a model ever since the development of quantum mechanics and Albert Einstein's theory of relativity in the early 20th century. 

Each of these pillars of modern physics describes its respective area of inquiry — the very smallest and the most massive things in the cosmos — with astounding accuracy, but both quantum mechanics and relativity fail when applied to each other's subject matter. So far, an overarching theory of everything has eluded scientists, and some believe the ultimate goal is unrealistic.
