Assuming a flat, static spacetime, what would the effective force between two objects, with mass m1 and m2 respectively, separated by a distance r from one another, both moving in the same direction with relativistic velocity v, be ?
When Einstein conceived GR he added the cosmological constant in an attempt to create a static universe model. The problem with this was that it was unstable.
I've recently read about static spacetime (static spacetime admits a global, non-vanishing, timelike Killing vector field K which is...
