How does gravity accelerate an object? Or should I say, how does gravity, "not accelerate" an object but just get it to move faster and faster towards something, due to the curving of space-time?

Einstein's curvature of space-time stills holds sway in regards to that space distortion causing a "change in direction" which equals acceleration while if gravitons (predicted by string theory) are ever discovered, than these particles would be a likely cause of the acceleration of mass.  One of the single, still unknown mysteries of physics is how to combine Einstein's GR (General Relativity) with string theory.
