     While the gravitational potential of that cannonball then   
     should travel outwards with speed c, that should not be a   
     gravitational wave, which is a transversal wave. However,   
     I'm not a expert on this. Moreover, I'm not sure whether   
     current theories deal with such out-of-nowhere matter at   
     all and can be applied to it.
