OJ287 binary black hole system perihelion shifts
J= - 1.731669280*10^16 total angular momentum per unit mass and E= 1.015569493 total energy per unit mass. Weinberg gives in his book p. 187 formula for dP/dt = J*(1-2*M*G/r)/r^2, M=3.648591540*10^43 g. G=6.674083100*10^(-8), c=1 and cgs units. I give this due orbit seems to be strange pendulum orbit with no proper aphelion. Best Regards, Hannu Poropudas, Finland.
