The giants arcs as modeled by the superbubbles
  The giant arcs in the clusters of galaxies are modeled in the framework of
the superbubbles. The density of the intracluster medium is assumed to follow a
hyperbolic behavior. The analytical law of motion is function of the elapsed
time and the polar angle. As a consequence the flux of kinetic energy in the
expanding thin layer decreases with increasing polar angle making the giant arc
invisible to the astronomical observations. In order to calibrate the
arcsec-parsec conversion three cosmologies are analyzed.
