We solve N=(8,8) super Yang-Mills theory in 1+1 dimensions at strong
coupling to directly confirm the predictions of supergravity at weak
coupling. We do our calculations in the large-N_c approximation using
Supersymmetric Discrete Light-Cone Quantization with up to 3*10^{12} basis
states. We calculate the stress-energy correlator <T^{++}(r) T^{++}(0)> as a
function of the separation r and find that at intermediate values of r the
correlator behaves as r^{-5} to within errors as predicted by weak-coupling
supergravity. We also present an extension to significantly higher
resolution of our earlier results for the same correlator in the N=(2,2)
theory and see that in this theory the correlator has very different
behavior at intermediate values of r.
