Astrophysical Constraints on the Gravitational Constant
Abstract
We study the astrophysical bounds on the change of the gravitational constant with time. We found that |Ġ/G|<10-12yr-1 is the condition that has to be satisfied in order not to cause a conflict with the observations. We find the condition to be in accord with the lower limits, the superstring theory predicts.
