NOTES
Solutions to Einstein's equation for orbits exist
Stable for test particles, very slowly decaying for massive particles
Observed decay of binary systems match predictions
Einstein's equation has light speed built in
Therefore, the model in which van Flandern has shown the flaws, isn't GR - he's oversimplified the theory to do his calculations
What's missing? This is:
Tensor field contains information about the direction to the source, and how that direction changes, allowing a steady motion to be anticipated
