Kardashev Scale Wiki

A Type II or K2 civilization has control over their solar system, and may be able to harness the power equivalent of a single star. It extracts fusion energy, information, and raw-materials from multiple solar systems; it is capable of evolutionary intervention, interstellar travel, interstellar communication, stellar engineering, terraforming, and star cluster-scale influence; the resulting proliferation and diversification may negate the probability of extinction. Complete control of the fate of its home planet where threats like ice ages and global warming can be avoided.

A utopian outcome would be a hybrid galactic culture, with millions of cooperating worlds in a galactic community. Poetically, this would be a mammoth archipelago of solar system societies, a multitude of civilized islands separated by the vastness of the oceans of space.

A dystopian path is also possible. Aggressive and ruthless expansion could lead to an uncontrolled sprawl far beyond any form of functional government, regressing into societal collapse and eventually a form of interstellar barbarism with little regard for life.

Detail

Energy usage 1026 W to 1036 W. Total usage is the same as Type I multiplied across star systems.
Population 100 Quadrillion (1017) people
Existence 4d (awareness of 5d) and 1r (reality)
Travel
Quality of life (government)
  • Adhocracy: flexible, adaptable, multidisciplinary government ideally suited to interstellar sprawl; opposite to bureaucracy
  • Hegemony: interstellar sprawl or alien influence leads to sector dominance
  • Military: protection against alien invasion or uncontrolled dissent might lead to a dystopian society ruled by an iron fist
  • Post-scarcity utopia: achieved once the species is beyond interstellar barbarism and has settled into sophonce, or the best path to progressing in civilzation.
State of forms Hive minds (surrogacy or avatar)
WMD scale Trans-dimensional; monopole enhanced nuclear weapons; Q-ball world destroyers
Longevity 350 – 500+
Industrial revolutions
Social issues
Arguments
  • Synthetic life
  • Spacer psionics
Dominant proliferation
  • Dimensional miscegenation cults
  • Unified transhuman society
Social weakening Dimensional fallout or hyper radiation where dimensionally alternate 2d has disastrous effects on health (solution – Avatar allowing re-hosting of the contaminated)
Social dream Eden or religiously motivated megastructure projects
Class system Ideology meaning the general availability of superiority makes your motivations and commitments a value set

Sub-Types

2.0

Interstellar age

2.1

HoloAge

2.2

XenoAge

  • Power consumption: 1028 W to 1029 W
  • 100 star systems colonized.
  • Meeting with alien species, and either trading or warring with them (assuming similar levels of advancement).
  • Interstellar communication systems are being developed.
  • Weapons become used only against alien threats. Interstellar tracking systems are developed around the Dyson sphere which could be transitioning from a swarm to a secure solid sphere as more solar masses are gathered.
2.3

Transhuman age

  • Power consumption: 1029 W to 1030 W
  • 1,000 star systems colonized.
  • Natural wormholes are explored.
  • First object sent to intergalactic space.
  • As the transhuman era emerges, humanoid settlers begin to become independent in their own colonies.
2.4

Posthuman age

  • Power consumption: 1030 W to 1031 W
  • 10,000 star systems colonized.
  • Ability to use wormholes and devices like stargates, as some faster-than-light technology is too slow for vast interstellar distances.
  • Beginning of the posthuman era; the species of the planets colonized in the past by humans become a separate people with their own culture.
2.5

Age of essence

  • Power consumption: 1031 W to 1032 W
  • 100,000 star systems colonized.
  • First time travel using relativistic time dilation.
  • Huge Matrioshka brains are created, capable of making a civilization and its data become at one with itself. Dyson spheres are now solid.
2.6

Dark Matter Age

  • Power consumption: 1032 W to 1033 W
  • 1,000,000 star systems colonized.
  • Species now may move towards sophonce and be one of the leading civilizations in a bustling galaxy of cooperation and trade, and respond to common threats.
  • Dark Energy reactors are built and there are multiple catastrophic core failures.
2.7

Second Magnetic Age

2.8

Black Hole Age

2.9

Galactic Age

  • Power consumption: 1035 W to 1036 W
  • Galaxy Colonized.
  • Remote contact with aliens from another galaxy. A higher type civilization could support the pre-K3 civilization, with late-K3 alien civilizations potentially helping the civilization.
