String Theory posits that the universe's fundamental particles are one-dimensional strings, whose vibrations determine particle properties. It seeks to unify quantum mechanics and general relativity, explaining all forces within a ten-dimensional framework. The theory's development, from describing the strong nuclear force to a potential 'theory of everything', has influenced both physics and mathematics, introducing concepts like supersymmetry and extra spatial dimensions.
