Overall, technology in 2071 is very advanced, but limited by the complexity barriers: systems cannot become too complex, or they break down. "Big" technology like antimatter, space travel and terraforming works well, but organising a trillion nanodevices or writing a good AI is too complex to be achieved.


Nanotechnology has been around since the 2040's. Due to the complexity limitations it is rather inflexible, but it is possible to make nanomachines for different purposes. They are mainly used for chemical processing, smart materials, nanocomputers and making diamond in bulk. Terraforming is one of the biggest applications, and worries about runaway nanodevices are calmed by using them on uninhabited planets.


Optical computers or nano-manufactured computers. Extremely powerful computer networks and programs, but heavily subdivided and fortified from evolving viruses. All developed nations are part of a dynamic information economy.


Genetic algorithms create dangerous viruses if allowed to develop freely. Expert systems and neural networks produce reasonably good AI but not super-intelligent (except for within very narrow areas).

Space travel

Expansion at first motivated by energy shortages, later by overpopulation and environmental problems. The orbital habitats (immense rotating cylinders with internal artificial ecosystems) provide both clean environment, safety and living space. There are colonies in orbit and on planets in the solar system as well as elsewhere.


It is possible to create gravitational monopoles (either attracting or repelling), dipoles (can be used for drives, antigravity or as engines) and multipoles (usually only of academic interest). Gravitech requires a lot of energy.

Pulsed gravitech gobbles up huge amounts of energy but can produce extremely strong fields for a short time; mainly used for FTL.

Soliton transmitter: a way of sending FTL signals. It has low bandwidth, is very energy demanding, heavy and easily eavesdropped.

Human agrav uses metallic hydrogen in plates held together by diamond sandwhiches and superconducting coils (Varaiyas-modules). The most common for are the g-modules, hexagonal prisms 10 cm long and 2 cm wide, or 10 cm diameter and 2 cm thick. Usually they consist of massive diamond with coolant vents for superfluid helium.


Based on the Alcubierre warp drive geometry invented in the 20th century, but possible to implement first in 2026 using gravitational technology.

The Guest-Asali drive consists of a fan of "thorns" that are unfolded when activated or when returning to status geometry. They are connected to a central reactor using waveguides. In the reactor an electromagnetic pulse is created, which creates a soliton wave. Around the reactor there is a thick layer of quantum computers doing the detailled control.

Warping requires much power for starting, and a gravitational "short-circuit" for slowing down. Horrible stories circulate about ships who failed to slow down and ended up stranded light-years from any star or swept away into infinity.


Antimatter is produced in "amat farms", huge solar cell arrays where energy powers big destillation units. The antimatter is stored as frozen antihydrogen kept in place using intense magnetic fields between superconductors.

All amat containers are standardized and have at least three levels of backup.

Missiles: small (50 cm) pen-like systems with a small pellet of anti-ice as warhead. The destructive power is equal to nuclear weapons.

Hellflowers: anti-planet weapons. A charge of antimatter detonates in the stratosphere and irradiates the surface of the planet with gamma rays, killing everything within line-of-sight below.

Amat motors: combines water ice with antimatter. The amount of antimatter needed is quite small, and can be kept in small modules that can be ejected if they are damaged. Amat motors are easy to trace from their heat traces and secondary gamma emissions from the steam/plasma. Antigravity motors are extremely power-hungry but stealthy.
