heat death
Quick Summary
The "heat death" of the universe is a hypothetical ultimate state of thermal equilibrium. According to the laws of thermodynamics, the universe, as an isolated system, is constantly increasing in entropy. Entropy is a measure of disorder within a system. As entropy increases, all parts of the universe will eventually reach a uniform temperature, resulting in zero available energy for useful work. This state of maximum entropy implies that no further changes or processes would be possible.123
