Query: On Gravitational Casimir Effect and Stefan-Boltzmann Law at Finite
  Temperature   Gravitons are described by the propagator in Teleparallel gravity in nearly
flat space-time. Finite temperature is introduced by using Thermo Field
Dynamics formalism. The Gravitational Casimir effect and Stefan-Boltzmann law
are calculated as a function of temperature. Then an equation of state for
gravitons is determined.
