2097 - Large civilian population on Mars
22nd - 23rd centuries Edit
2101 - Start of the terraformation of Venus
2103 - FTL technologies becoming a reality
2108 - Probe to Alpha Centuri
2113 - Planetary colonies are gaining independence from Earth.
2114 - Manned colonization of Saturn's moons (Mainly to study methane based life)
2127 - Probes to exo-planets
2136 - Possible discovery of microbes on exo-planets
2141 - Asteroid Terrorism
2157 - Supreme weapon systems
2165 - A large chunk of Mars is now habitable
2178 - Phobos and Deimos are now large mining colonies, supplying Mars with minerals
2182 - Martian space elevator
2187 - Venusian space elevator
2190 - Manned colonization of the entirety of the solar system, humans have entered the Galactic Stage
2201 - Manned colonization of exo-planets
2200s - Superhuman powers
2220s - Guns are made useless
2250s - The human race is adapting to different enviroment
2270s - First definite contact with extra terrestrial lifeforms.
23rd - 31st centuries Edit
2300s - Rich businessmen buy whole solar systems to build colonies. Some of these aren't accessible at the current technologies
2400s - Humans are adapting to different environments
2500s - A large chunk of multiple terraformed planets are habitable.
2600s - Force fields are now in military use
2700s - Intelligent alien races are in contact
2800s - 3000s - At some point in this period, interstellar colonies are having interstellar wars. The result is multiple habitable planets are now destroyed by multiple weapons such as planetkiller arrays, asteroid redirection and global disasters.
2900s - Diamonds are worthless, now 55 Cancri E has now a permanent mining colony.
3000s - The solar system is privatized, with a Dyson sphere around Sol to power a system-wide force-field and toll booths
3rd - 10th Millenniums Edit
4000s - Colony ships are now bringing civilians to 'Rimworlds' or Earth-like planets. They tend to find destroyed cities, structures and information from precursor races that have destroyed themselves.
