I have to thank you. From the replies you've gotten I got a new insight. What Stenger said and what you have been told by actually practicing physicists is that within GR there is no force of gravity. It is the force that is being discussed not gravity.
Quite.
To expand on my quotations from physicists:
Back in the Middle Ages, people would have told you that the natural state of a body was to be at rest. If it moved, some force must be moving it.
Following Newton (whose own terminology was somewhat confused, but had the right idea) people came to realize that this was false. The natural state of a body was to move in a straight line at a constant velocity and it took the application of
force to make it do something else. Its natural state was to move in a straight line (in Euclidian space).
But then along came Einstein and said that the natural state of a body was to move along a geodesic (the equivalent of a straight line) in Einstein's space, (which was not Euclidian but was bent by the presence of mass) and it would take an external force to make it do something else. Newton's "force" of gravity explaining why things didn't move in straight lines was, from this perspective, like the medieval concept of the "force" that explained why things didn't remain at rest. It would take a
force to prevent the Earth from orbiting round the Sun;
without a force acting on it that is what it would do.
