“The gravitational quantum metrological triangle may have applications in metrology and could be used to investigate the relation of the Planck constant to fundamental particle masses,” the ...

{r^2}\) The constant of proportionality is the universal gravitational constant ("big G") which equals \(6.674\times{10^{- 11}}N{m^2}k{g^{- 2}}\). Overall this equation is simpler than it looks as ...
