Welcome to the Kardashev Scale Wiki

The Kardashev scale is a method of measuring a civilization's level of technological advancement, based on the total energy usage of a civilization. The scale is exponential and hypothetical and regards energy consumption on a cosmic scale. It was proposed in 1964 by Nikolai Kardashev and modified in 1973 by Carl Sagan, which is the scale we use.

The purpose of this wiki is to include an exhaustive list of sapient human and alien civilizations with an attempt to classify their origins, existence, technologies, computing level, energy usage, longevity, travel, communication, possibility of extinction, and so on. When categorizing civilizations, we take factors like data usage, travel capabilities and sub-type predictions into account, in addition to energy usage.

This wiki is a fusion of real science, theoretical science, hypothetical science, and futurism. There are many futures, or infinite futures, so grab a chair and enjoy this content with an open mind. Come chat on our Facebook Group or on Discord.

Commercially published books, movies or games must be cited, and links to their Fandom pages are encouraged. Fiction is allowed, but must feel as a natural extension and not contradict a pre-existing page. Alternatively, content can be taken from established fiction and/or non-fiction.

A sci-fi book about accelerated evolution and near-future real and hypothetical science can be found here.

We have finally decided to move from the old Roman numerals to decimals. All sub-types are fine-grained, so this makes it scientifically accurate. We think this gives it a modern look and adds flexibility and clarity.

Civilization categories of the scale

Type 0	K0	Pre-planetary	Extracts its energy, information and raw materials solely from planetary resources, and can travel beyond its home planet.
Type 1	K1	Planetary	Can use and store the equivalent of all of the energy in and reaching its home planet, and become interplanetary.
Type 2	K2	Stellar	Can harness the total energy equivalent of an entire star's output, and become interstellar.
Type 3	K3	Galactic	Can control energy equivalent on the scale of an entire galaxy, and become intergalactic.
Type 4	K4	Universal	Can control the energy equivalent of its home universe, have instantaneous travel, and manipulate the fabric of spacetime.
Type 5	K5	Multiversal	Can escape their universe of origin and explore the multiverse, and have time travel to the future.
Type 6	K6	Megaversal	Can exist in an infinite amount of simultaneous multiverses and instances, with unlimited spacetime travel.
Type 7	K7	Omniversal	God-level traveler and manipulator of all universes, multiverses, and megaverses.

There are also Microdimensional categories of the scale proposed by John Barrow. This reverses the classification downward from Type 1-minus to Type Omega-minus.

In an attempt to classify all of existence using the concept of realms, the scale has been extended thus:

Navigation to Kardashev Type

 Omniverse: Type 0 - Type 1 - Type 2 - Type 3 - Type 4 - Type 5 - Type 6 - Type 7
Hyperverse: Type 8 - Type 9
Outerverse: Type 10 - Type 11 - Type 12 - Type 13
   Adverse: Type 14 - Type 15 - Type 16 - Type 17 - Type 18 - Type 19
    Beyond: Type 20. This is the final official type.
