We also have the flyby anomaly where multiple space probes flying past the earth do not exactly match the predictions of GR. So is GR therefore falsified?
I haven't really seen science work that way, since it isn't all that often we base our expectations solely on things we can completely account for. Science necessitates a certain amount of calculated projection. Theories are adjusted as new details are discovered, and only fools entertain themselves by resisting the bigger leaps needed to make actual discoveries.
The obvious parallel was https://en.wikipedia.org/wiki/Pioneer_anomaly which was finally solved. But who know at this point?
Personally I think GR has to be "wrong", since it conflicts with QM, and if the 20th century showed us anything it's that QM alway wins.
