A Type II or K2 civilization has control over their solar system, and/or theoretically is able to harness all the power available in 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 would theoretically negate the probability of extinction.


Energy usage: 1026 W to 1036 W, Dyson sphere, Star lifting

Estimated Population: 100 Quadrillion (1017) people

Travel: alpha jumps (space folding)

Quality of life (gov): adhocracy, plutocracy

State of forms: hive minds (surrogacy or Avatar)

WMD scale: Trinity project

Longevity: 200 – 500

Social issues: Artificial Planet creation, Synthetic Life, Avatar prostitution, manipulating the Cultural focus of other species, Xeno Propaganda, trans-dimensional wmd, Dyson spheres, Dimensional portals to 3 universally different branes

Industrial revolutions: Dimensional portal, Dyson sphere

Arguments: Synthetic life, Spacer psionics

Dominant proliferation: dimensional miscegenation cults

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 mega structure projects

Class system: Ideology meaning the general availability of superiority makes your motivations and commitments a value set
