Query: Relativistic Gravitational Collapse by Thermal Mass   Gravity and thermal energy are universal phenomena which compete over the
stabilization of astrophysical systems. The former induces an inward pressure
driving collapse and the latter a stabilizing outward pressure generated by
random motion and energy dispersion. Since a contracting self-gravitating
system is heated up one may wonder why is gravitational collapse not halted in
all cases at a sufficient high temperature establishing either a gravo-thermal
equilibrium or explosion. Here, based on the equivalence between mass and
energy, we show that there always exists a temperature threshold beyond which
the gravitation of thermal energy overcomes its stabilizing pressure and the
system collapses under the weight of its own heat.
