The Kardashev Scale is a concept developed by the Soviet astronomer, Nikolai Kardashev, to measure the level of advancement of civilizations based on their energy consumption. The scale consists of types I, II, and III, corresponding to the energy levels needed to control the resources of a planet, a star, and a galaxy, respectively. Some synonyms for the Kardashev Scale could be the "Civilizational Energy Scale," the "Intelligence Energy Scale," or the "Cosmic Energy Index." These terms emphasize the relationship between a civilization's advancement and its ability to harness energy from its surroundings and highlight the potential for cosmic expansion and achievement.
