From string to M-theory
The ultimate objective of physics is that unifying all natural interactions by a theory, and then describes the origin of universe.
Up to now, physicists have described the strong, weak, and electromagnetic interaction in QFT, however the gravity still only in the frame of general relativity.
String theory is a quantum theory in essence, also a theory which can interpret gravity. Thus, string theory is a primary candidate for the "Theory of Everything".
