| Abstract: | We investigate the gravitational collapse of a spherically symmetric, inhomogeneous star, which is described by a perfect
fluid with heat flow and satisfies the equation of state p=ρ/3 or p=C
ρ
γ
at its center. Different from the ordinary process of gravitational collapsing, the energy of the whole star is emitted into
space. And the remaining spacetime is a Minkowski one at the end of the process. |
