In this final state the universe is one uniform space where nothing happens and no work (moving something) can be done since there are no above average concentrations of energy left.
In this final state the universe is one uniform space where nothing happens and no work (moving something) can be done since there are no above average concentrations of energy left.
This state is called maximum entropy and is said to be in perfect disorder (although intuitively its uniformity would seem to be a state of perfect order) because it has become impossible to determine what happened in the past. ''i.e.'' There are an infinite number of ways (histories of the universe) maximum entropy could have been reached.

Some scientists think of the Second Law of Thermodynamics as being one that can sometimes allow local entropy decrease. This was corrected with the [[Generalized Second Law of Thermodynamics]].
