Query: Energy emission from high curvature region and its backreation   A strong gravity naked singular region can give important clues towards
understanding classical as well as spontaneous nature of General Relativity. We
propose here a model for energy emission from a naked singular region in a
self-similar dust spacetime by gluing two self-similar dust solutions at the
Cauchy horizon. The energy is defined and evaluated as a surface energy of a
null hypersurface, the null shell. Also included are scenarios of spontaneous
creation or disappearance of a singularity, end of inflation, black hole
formation and bubble nucleation. Our examples investigated here explicitly show
that one can model unlimitedly luminous and energetic objects in the framework
of General Relativity.
