Magnetism has be explained as a relativistic effect of moving charges. This was something we were shown in undergrad.
Is there a similar effect when masses move relative to each other?
1. Is there any difference between the gravitational force between a single massive particle and a very long "line" of mass at rest wrt the particle versus when the "line" of mass is traveling at relativistic speeds (in the same direction as the line) in relation to the particle?
2. Is there any difference between the gravitational force between two parallel lines of mass at rest wrt each other versus the lines of mass traveling at relativistic speeds (along the same directions as the lines) in relation to each other?
Why?
