Construction begins on Dyson Sphere or Alderson disk.ß, Stress caused by size of civilization, at this point it can fragment into multiple planetary civilizations—reversion from single civilization early in type 1
Trends:
Increasing levels of technology, Increasing levels of space exploration, space based energy sources increase, offworld civilization centers increase, increasing energy usage, increasing area of habitation
decreasing levels of centrality, societies and civilizations increasingly are not the same, due to time differences breaking single social bonds 1
Stress caused by size of civilization, at this point it can fragment into multiple solar system based civilizations—reversion to single star based civilization early, Automated Galatic colonization effort may begin 3
Trends:
Increasing levels of technology, Exponential growth in stars that are colonized, centralized systems increasingly draw resources from further systems which have not had their resources harvested–– driving increased expansion
decreasing levels of centrality, increasing likelihood of fragmentation into single star systems if resources cannot be adequately transferred from central sources, resource based wars may remerge after disappearance during Type I
Highly hypothetical at this point, there are no proposals for this level.
Trends:
Increasing levels of technology, centralized systems increasingly draw resources from further systems which have not had their resources harvested–– driving increased expansion
Slow growth in galaxies that are colonized due to speed limitations, making centrality impossible
