SUMMARY
Gravitational waves cannot exist in a truly static spacetime, as their presence inherently introduces time derivatives, thus making the spacetime non-static. The discussion highlights that while gravitational waves can be analyzed as small perturbations on a static spacetime, this approach contradicts the definition of static conditions. The consensus is that gravitational waves are fundamentally linked to dynamic spacetimes, particularly in expanding models.
