In GR Mass is said to curve spacetime which is the explanation for Gravity versus Newtonian physics where it is explained as all matter attracts each other. My question is how does curved spacetime cause objects traveling at different velocities to follow different paths? If gravity was only due to spacetime being curved shouldn't objects follow the same path they are own regardless of their velocity?
In Newtonian physics it makes sense that objects with higher velocity with regard to a gravitating mass would be less effected because they spend less time near it as they pass by and so less acceleration is done to them. the object would follow a curved path dependent on it velocity with a flatter curve the faster it travels.
So, the only explanation I could come up with in GR would be that curvature of spacetime is relative velocity dependent meaning that the faster you are traveling relative to another object the flatter spacetime is due to gravity from that object. Is this what GR actually says? or is it explained another way?
