Time Variation of the Gravitational Constant,s have limited the variation to be less than 10.yr.. In the next few years, that limit may be reduced as a result of the Soviet-Franco-American dynamics experiment on the Soviet mission to Phobos in 1990.

https://doi.org/10.1007/978-981-97-6814-1We review some . models to calculate the dimension less constants α = e./4πε.ћc, β = M./m. (or β′ = m./m.), γ = G. m./cћ. and δ = G. m./4πε.) which are associated with the four different . (electromagnetic, strong, weak and gravitational) of a possible single interaction.

Sichao Tian,Peiyan Yuan,Qing-Hua XuWe like to consider two astrophysical empirical laws, try to give some theoretical basis for them and to show that the fine structure constant α is a typical dimensionless parameter not only of atomic physics but also of gravitational physics.
