What is the Kardashev Scale, and what does it measure?
gpt
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 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 planetary system, and a Type III civilization—also called a galactic civilization—can control energy at the scale of its entire host galaxy.
