We present a numerical model of a collapsing radiating sphere, whose boundarysurface undergoes bouncing due to a decreasing of its inertial mass density(and, as expected from the equivalence principle, also of the ``gravitational''force term) produced by the ``inertial'' term of the transport equation. Thismodel exhibits for the first time the consequences of such an effect, and showsthat under physically reasonable conditions this decreasing of thegravitational term in the dynamic equation may be large enough as to revert thecollapse and produce a bouncing of the boundary surface of the sphere.Comment: 14 pages, 6 figures.
