Timeline for the /sci/verse:
2000/2100: The Diamond Age
Nanotech Revolution, wealth reaches every level of society, expansion into space by independent groups of like-minded nerds that now have the means to build their own spacecraft.
2050: First multi-purpose, fully-functional, Drexlerian molecular assembler built. Soon spreads into the general public.
2054: Telepresence becomes a standard formality in most countries across Asia and the Americas.
2055: Earhport is built on Lima November One site.
2057: Large settlements on the Moon.
2058: Fullairs in cities work as aeroponic farms.
2060: First commercial low-scale fusion plant.
Lightcraft from Earthport take 2000 tonnes of cargo into space every day, spaceplanes and Lightcraft in total take 20,000 people.
2070: Construction of the Asimov Array begins.
2077: Mercury Power Project begins.
2081: Ceres Settled
2090: Destructive, partial, error-prone mind uploading.
2100/2500: The Golden Hour
Most of the solar system is settled, huge economic growth and trade, massive megastructures built using molecular nano, no posthuman AI but genetically-engineered posthumans are created. Great Houses begin to form, most of them ruled by the posthumans, sometimes openly, sometimes secretly.
2110: First Sidehuman (Humans modded so they are different from humans,
but not necessarily posthuman. See also: Baseline human, nearbaseline).
2111: Banks Orbital in orbit around the Sun.
2115: 50,000 people living on cisjovian space.
2117: Luddite Revolution
2120: Chimaera for military purposes.
2128: Luddite takeover of Earth, most commerce and immigration/emmigration cut.
2130: Fullairs on Titan.
2135: 400,000 people living off-Earth.
2140: First manned, relativistic (0.6c) interstellar mission.
2145: Microbot assemblers (Molecular assemblers mounted on microscale robots)
2175: First O’Neill cylinder, Lagrange.
2230: Arcologies on Earth and Mars
2250: Underground settlements underneath Venus.
2301: Nanobot assemblers (Molecular asseemblers mounted on nanoscale robots).
2500/3400: The Interstellar Age
Expansion into the interstellar medium objects (Brown dwarfs and icy planetoids) and into other star systems by the Great Houses, manned missions often precede the first settlers.
3400/3800: The First Great War
War erupts between the Great Houses of Sunspace that have begun to use more advanced weapons against each other, the posthuman-run Houses play their little game of chess with trillions of human and posthuman lives. Most of the solar system left uninhabitable, with the notable exceptions of Venus, Earth, the Moon, and Mars, which were sterilized but soon recovered by some groups of posthumans.
3800/4200: The Land Rush
As billions of refugees escape into interstellar space, the current colonies turn to beacons signaling shelter, but these soon are crowded, so most settle for the Oort cloud, the brown dwarfs and other objects in the interstellar medium, while other nearby systems are colonized.
4200/4800: The Settlement Age
Most of the refugee-funded colonies, along with the previous ones that had to start themselves without any help or commands from the original Great Houses, have finished their settlement, and have established their limited borders and names as polities.
4800/8100: The Guild Age
Most of the large polities soon form 'Guilds': Most research is kept as a Guild secret and most trade is handled by them. The masses have little access to mass communications, and even though they are granted some access to immortality and nanotech, this is determined by governments that are often run by posthumans or superhumans.
8100/19,900: The Second Great War
A war erupts between the Guilds, this time, monopole-catalyzed fusion bombs and relativistic bombs are used, rendering most of the targets uninhabitable.
19,900/34,000: The Rediscovery
With most of the inhabited habitats driven to new Dark Ages (The cycle of wars and restarts of civilization is a characteristic of the setting's cyclic history) a few people that escaped the war come back and reintroduce science to the decimated habitats. Some are worshipped as Gods and chose to start a pastoral/feudalist system.
Other civilizations carried the torch of science and managed to recuperate, but this process was just as slow as the others.
34,400/45,000: The Commonality Age
Most of civilization has recovered now, and a group rules above most: The so-called Commonality of Mankind, a benevolent group of people. Individual polities have their power, but the Commonality, with endless tools at their disposal, enforces their policy and keeps peace on most worlds.
45,000/67,300: The Expansion Age
Driven by an economic Golden Age brought by the Commonality, relativistic exploration of the galaxy begins. Fake saints, true morons, bold explorers, believers and people trying to get rich, all embark on the expeditions to new worlds.
67,300/89,700: The Galactic Age
Most of the Galaxy has been colonized. This era has a sense of widespread “Galactic Community”. Few sentient alien species have been found, and the Commonality has enforced peaceful First Contacts with as many as possible, although this could not be guaranteed on all cases.
89,700/100,000: The Exploration Age
Exploratory missions are sent to the nearby galaxies, dwarf galaxies, using a network of faster-than-light Krasnikov tunnels that posses negative energy densities. These connect the long-distances between galaxies, star clusters, and satellite galaxies and dwarf galaxies, but they do not reach into the stars within a galaxy: Slower-than-light travel still remains a constant within the galaxy, but people got used to it.
100,000/Deep Time: The Long Years
Civilization continues to expand, there are billions of settled worlds, planets, moons, wandering moons, interstellar planets, suns, gas giants, brown dwarfs, Halo worlds, colonies in interstellar space. The human species has split into millions of subspecies, sometimes out of curiosity, others out of need, worlds have been disassembled, others put together, circumstellar megastructures built. Life exists in incredibly different types, organic life, mechanical life, electronic life, quantum life, chemical-pool life, and endless others. Some civilizations have become incredibly advanced, and have taken forms incomprehensible to humans and posthumans. There are Dyson spheres and people who have chosen to live virtual lives in the complex information ecologies. Most civilizations don't use “Maximum Efficiency Paradigms”, that is, they don't force billions to upload to computronium or Dyson Sphere every star in the galaxy: After all, if some species have proven that we have barely scratched the surface of what is possible, why the rush? There's no need to attempt to outrun the Heat Death, since eventually, we'll be able to reverse that – Or restart that.
Life goes on, civilizations reach apotheosis, others end themselves.
