In What Could Be a Decisive Moment in Physics, a Major Breakthrough for SuperString Theory: Precision Lattice Test of the Gauge/Gravity Duality at Large-N – the First Confirmation of the Supergravity Prediction We pioneer a systematic, large-scale lattice simulation of D0-brane quantum mechanics. The large-N and continuum limits of the gauge theory are taken for the first time at various temperatures 0.4 ≤ T ≤ 1.0. As a way to directly test the gauge/gravity duality conjecture we compute the internal energy of the black hole directly from the gauge theory and reproduce the coefficient of the supergravity result E/N2 = 7.41T 14/5 . This is the first confirmation of the supergravity prediction for the internal energy of a black hole at finite temperature coming directly from the dual gauge theory. We also constrain stringy corrections to the internal energy.
