My theory is based on this fact but does not need G, M or GM to predict/calcualete vtr. > Until you reveal you formulas, we cannot pointed out, where they are wrong. As they ARE wrong if they need not G, M or G.M For a small object on circular orbit of radius r and speed v, the needed centripetal acceleration a_cp = v^2 / r = (2.pi.r/ T)^2 / r = 4.pi^2. r / T^2 For a small object orbiting on circular orbit the object of mass M, the gravitational acceleration of classical gravity is a_gr = G.M/r^2 As a_gr must be equal a_cp, therefore for v: v^2 / r = G.M/r^2 v = sqrt (G.M / r) resp. for T > 4.pi^2. r / T^2 = G.M/r^2 4.pi^2. r^3 = G.M . T^2 T = sqrt ( 4.pi^2. r^3 / (G.M)) And now, tell us, how can you calculate v or T from r without G and M or G.M..
