| Abstract: | We study the astrophysical bounds on the change of the gravitational constant with time. We found that | /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. |
