I want to understand physical meaning and possible implications of few terms often used in physics specially with regards to gravitational waves / space-time fabric
Space-time fabric is disturbed by the presence of a body. The body produces ripples which propagate like waves. Does it mean that the only way for these ripples to be formed is when an object is created (possibly from energy or from events like black holes merger etc)?
If Space-time fabric is disturbed by bodies, does their movement also disturb it? Meaning, if a body moves, does it also cause ripples in the space-time fabric?
If waves are induced in space-time fabric by bodies, can we expect phenomenon like "turbulence in fluid mechanics" to be present in gravitational waves too?
