  The cannonball model (CB) of gamma ray bursts (GRBs) is incredibly more
successful than the standard blast-wave models (SM) of GRBs, which suffer from
profound inadequacies and limited predictive power. The CB model is falsifiable
in its hypothesis and results. Its predictions are summarized in simple
analytical expressions, derived, in fair approximations, from first principles.
It provides a good description on a universal basis of the properties of
long-duration GRBs and of their afterglows (AGs).
