    This is perhaps the most common question about general relativity. If gravity isn't a force, how does it accelerate objects? General relativity says that energy (in the form of mass, light, and whatever other forms it comes in) tells spacetime how to bend, and the bending of spacetime tells that energy how to move. The concept of "gravity" is then that objects are falling along the bending of ...
