E8×E8 heterotic string theory

E508536

heterotic string theory quantum gravity theory

E8×E8 heterotic string theory is a ten-dimensional string theory whose gauge symmetry is based on the product of two exceptional Lie groups E8, making it a leading candidate for unifying gravity with the forces and particles of the Standard Model.
