The two-dimensional XY spin glass is studied numerically by a finite size defect energy scaling method at T0ex0ex=0ex0ex0 in the vortex representation which allows us to compute the exact (in principle) spin and chiral domain wall energies. We confirm earlier predictions that there is no glass phase at any finite T. Our results strongly support the conjecture that both spin and chiral order have the same correlation length exponent νₛ0ex0ex=0ex0exνc≈2.70. Preliminary results in 3D are also obtained.
