Query: Dynamical Origin of Duality between Gauge Theory and Gravity   Dynamical origin of duality between gauge theory and gravity is studied using
the dual transformation and the formation of graviton as a collective
excitation of dual gauge bosons. In this manner, electric-magnetic duality in
gauge theory is reduced to the duality between gauge theory and gravity.
