Is GR flawed?
There are at least two inconsistencies that stand out:
1. An object approaches a star's gravity well. The linear momentum of the object is such that it becomes a satellite. As the satellite tends toward the star, from where is its momentum replenished, to keep it in orbit?
2. What is the force applied to the satellite that causes it to follow the space-time gradient toward the star. If gravity is a result of the curvature of space-time, from where does that force come ---since there is no tether (action at a distance) pulling them toward each other?
