heat death
Cosmos's final equilibrium
Heat death is the theoretical final state of the universe in which all energy has dispersed evenly, leaving no temperature differences capable of doing work.
In this scenario, entropy reaches maximum and all physical processes cease: The heat death of the universe means everything eventually winds down to cold, uniform stillness.
The term applies figuratively to any system running out of useful energy or activity.
