N2 - By using a computer to solve the ten-dimensional Einstein equations in superstring theories, we find that the present value for the time variation of Newton's gravitational constant is in the range of -1 × 10-11 to -6 × 10-12 yr-1 in the case of the flat internal potential, which confirms the previous perturbative estimate.
