Mati,
The loss to which I refer causes Mercury's perihelion to advance, but is
present in all of the orbits around our Sun. I don't fully grasp why the
entire orbit does not decay except that it is relativistic and makes the
orbit itself orbit. Thus my question.
Calculations have indicated to me that near a black hole, the advance can be
the entire orbit.
Sincerely,
