Einstein's space-time is a typical example of a so called "geometrized theory". It is an elegant mathematical presentation but hides the view to the physics behind.
Roman Sexl has once given the direction for a physical explanation of gravity: We know very precisely that the speed of light is reduced in a gravitational potential. If this is applied to a photon which passes the sun (e.g. the sun eclipse observation of 1922 which made Einstein famous), then the photon is subject to a classical refraction in the gravitational field. If this is computed, the result is exactly the one which was observed. There is absolutely no need to use space-time curvature to explain this.
If this refraction process is applied to the internal oscillations within an elementary particle, the particle's acceleration towards the source of gravity is also exactly what we observe. With conventional space-time. It also covers the relativistic aspects of it (like the perihelion shift of the planets.)

By my understanding this is true for most of the threats I have read here. And it is of no surprise. Einstein himself has only given descriptions and no explanations regarding relativity.
