| Popis: | We derive the dark energy fluid equation of state $P = -\epsilon = {\rm const.}$ as an extremum of entropy, subject to the Hamiltonian constraint of General Relativity. However, we identify perturbations that can render this extremum an entropy minimum designating a thermodynamic instability and specify the mathematical condition for this to occur. |
