The Kardashev scale is a method of measuring a civilization's level of technological advancement based on the amount of energy they are able to use. The measure was proposed by Soviet astronomer Nikolai Kardashev in 1964. The scale has three designated categories:

• A Type I civilization, also called a planetary civilization—can use and store all of the energy available on its planet.
• A Type II civilization, also called a stellar civilization—can use and control energy at the scale of its stellar system.
• A Type III civilization, also called a galactic civilization—can control energy at the scale of its entire host galaxy.
