<P> The heat death of the universe is a plausible ultimate fate of the universe in which the universe has diminished to a state of no thermodynamic free energy and therefore can no longer sustain processes that increase entropy . Heat death does not imply any particular absolute temperature ; it only requires that temperature differences or other processes may no longer be exploited to perform work . In the language of physics , this is when the universe reaches thermodynamic equilibrium ( maximum entropy ) . </P>
