Civilization types: - Type I: A civilization that can harness all the energy that falls on its planet from its parent star. - Type II: A civilization that can harness all the energy output by its parent star. - Type III: A civilization that can harness all the energy in its galaxy. The Earth can be seen as an [[Entropy|entropy]] machine. It receives low-entropy energy from the Sun in the form of sunlight, and it radiates this energy back into space as high-entropy heat. This process is what allows life on Earth to exist and evolve. The Kardashev Scale can be seen as a measure of a civilization's ability to control and manage entropy. The higher a civilization is on the Kardashev Scale, the greater its ability to control entropy and utilize energy efficiently. #kardashev-scale #humans #energy
