- The Kardashev scale is a method of measuring a civilization's level of technological advancement. The scale is only theoretical and in terms of an actual civilization highly speculative; however, it puts energy consumption of an entire civilization in a cosmic perspective. It was first proposed in 1964 by the Soviet Russian astronomer Nikolai Kardashev. The scale has three designated categories called Type I, II, and III. These are based on the amount of usable energy a civilization has at its disposal, and the degree of space colonization. In general terms, a Type I civilization has achieved mastery of the resources of its home planet, Type II of its solar system, and Type III of its galaxy. Below is the scale
* Type 0 - Only able to use a portion of a planet's energy.
* Type I - Able to use an entire planet's energy.
* Type II - Able to use an entire star's energy.
* Type III - Able to use an entire galaxy's energy.
* Type IV - Able to use an entire universe's energy.
* Type V - Able to use several universes' energy.
* Type VI - Able to use an entire super universe's energy.
* Type VII - Able to several super universe's energy.
* Type VIII - Able to use all of Havona's energy.
* Type IX - Able to use all of Havona's energy and beyond. As of 2099, humankind lays somewhere between Type I and Type II.
- The Kardashev Scale is a means of ranking a civilization (or similar entity or group) by measuring its power generation and usage capacity. It is often misunderstood by assuming that it measures size; however, a civilization that spans an entire galaxy might be of a lower type than expected if it does not actually use the entire galaxy's energy. The three basic types are as follows:
* Type 1.0 Civilization: Able to use the entire solar energy available to an Earth-sized planet. (1016 watts by Carl Sagan's definition of the scale.)
* Type 2.0 Civilization: Able to use the entire energy output of a star. (1026 watts)
* Type 3.0 Civilization: Able to use the entire energy output of a galaxy. (1036 watts) The decimals indicate that by more precisely measuring power usage, one can arrive at a value in between the main types; a civilization using 1021 watts could be considered Type 1.5. Various extensions to the scale have been proposed; two are particularly relevant here. One says that simply multiplying each new type's power by 1010 brings it to the next type, so a Type 4.0 Civilization would use 1046 watts, a Type 5.0 Civilization would use 1056, and so on. The other is to simply keep going up from the "planet, star, galaxy" progression, so a Type 4.0 would use the power of a universe, a Type 5.0 would use the power of a multiverse, a Type 6.0 would use the power of a megaverse, and so on. The Archverse chain would encompass all natural numbers after 12, 12 being Yottaverse, and the omniverse would be א0(aleph null).
