Kardashev Scale

The Kardashev scale is a method of measuring the power/territory of a group of entities. The measure was proposed by Nikolai Kardashev in 1964. The original Kardashev scale divides civilizations into Types 1-3, although extensions used on this wiki are also commonplace. In the original scale, a type 1 civilization corresponds to being interplanetary, type 2 is interstellar, and type 3 is intergalactic. Type 1 civilizations consume 10^16 watts of energy, type 2 consume 10^26, and type 3, 10^36. A hypothetical subplanetary Type 0 will consume 10^6 watts. However, we can continue with a type 4 civilization that could consume 10^46 watts, equivalent to harnessing a supercluster, and a type 5 possibly colonizing the entire observable universe. If energy usage becomes meaningless (e.g. negative types), then the amount of space colonized is used instead.
