According to Einstein, the constant would be a repulsive force that counteracts gravity, keeping the universe from collapsing in on itself. Einstein later discarded the idea when astronomical ...

{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 ...
