Dyson's eternal intelligence

Dyson's eternal intelligence is a theoretical framework, proposed by Freeman Dyson in his 1979 paper "Time without end: Physics and biology in an open universe," through which an intelligent form of life could perform an infinite number of computations, and thus experience an infinite subjective time using only a finite amount of energy. This concept relies on the life form adapting its metabolism and speed of thought to the decreasing temperature of an open, ever-expanding universe. The mathematical precision of the theory is rooted in the principles of thermodynamics, information theory, and the ultimate physical limits of computation.
