The use of metric engineering to manipulate the structure of space and time. Manipulation and fine control of space-time allows the creation of artificial wormholes, reactionless drives, and artificial universes. However almost all forms of space-time engineering can only be successfully performed by minds of a high toposophic level.
Deep Well Industrial Zone - Text by Todd Drashner Heavy duty industrial and manufacturing zones are most often found in the Inner Sphere and most heavily developed areas of the Middle Regions.
Displacement Cannon - Text by Adam Getchell and Todd Drashner A maneuverable explosive device with a range in the hundreds of light years that moves at close to light speed and delivers energies on the order of kilotons to gigatons. It depends on transapient level metric engineering. Very occasionally made available to modosophonts, most notably in the war against the Amalgamation.
Einstein Bridge - Text by M. Alan Kazlev Wormhole linking Sol System and Tau Ceti. It is the oldest macroscopic wormhole still in operation and, apart from a period during the Version War when it was shut down, it has been in continuous operation since the middle Expansion Age.
Grazer Wormhole - Text by Adam Getchell Purpose-built spherically symmetric wormholes carried into systems, such as globular clusters, that are rich in material and energy but (usually) poor in planetary materials.
Halo Drive - Text by Todd Drashner, Adam Getchell At Singularity level:5 Void Bubbles can be coupled to the craft using gravity and magnetic forces, and a halo of void bubbles can be established at the front of the ship, essentially dragging the vessel along behind it in real space.
Interstellar Spacetime Catapult - Text by Todd Drashner Halo Drive based accelerators used to launch cargo to relativistic or near-relativistic velocity. The rarity of the S5 (or higher) minds needed to construct them and supply the necessary control interfaces means that only fairly developed and rich systems that are not part of the Nexus can afford them.
Kepler Arc - Text by M. Alan Kazlev Important wormhole connecting Djed and Kepleria.
Known Net, The - Text by M. Alan Kazlev; additional comments by John Snead The interstellar information network and interlinked cybercosms that has grown over thousands of years from the old pre-singularity Internet and InterPlanetNet.
Light-cone - Text by Stephen Inniss The path that light created at a single point in space and time and travelling in all directions would take through spacetime. The concept of a light cone is important to an understanding of causality.
Reality Intertextualization Project - Text by Crossroads Project with the mission to detect other realities; determine, if possible, what conditions are like in these realities; and to contact any intelligent beings that may live there. In 10495, the RIP claimed to have detected indisputable evidence of intelligent life in one of these realms. Efforts to contact them are underway.
Relay - Text by M. Alan Kazlev A hardware node in the Known Net which usually includes computronium servers, docks, service stations, and multiple nano- and microgauge wormhole gates. In some cases, relays may also incorporate flat-space communication systems, and catapults for transport of cargo and hard matter data storage systems.
Relay001 - Text by Todd Drashner The first major wormhole plexus and relay system built in the Inner Sphere. Became the model for later Relay systems.
Shatterbomb - Text by Todd Drashner Godtech weapon that is believed to operate by creating a brief, intense and localized increase in the expansion of space-time resulting in the disruption of any matter within the affected volume.
Tipler Oracle - Text by Todd Drashner A semi-mythical godtech device said to be created by the AI Gods when they have a particularly intractable computational problem to resolve.
Valhalla Cluster - Text by Todd Drashner Colloquial term for massive artificial concentrations of matter believed to be operating as archai level (Fifth Singularity or higher) industrial centers.
Visser Effect - Text by Xaonon Principle that dictates that no system of wormholes can be configured in such a way as to permit time travel. The ends of any single wormhole cannot be brought more closely together than the time difference between them; i.e. if one mouth is a year younger than the other, the ends can't come closer than a light-year without causing a collapse.
Weylforge - Text by Todd Drashner A Weylforge is an array of devices handling different aspects of wormhole construction.
Wormhole Bus - Text by M. Alan Kazlev, with additions by Steve Bowers Dedicated hyperbandwidth wormhole used to link remote parts of megascale brains in order to avoid the effects of the Beckenstein Bound. An essential part of archailectarchitecture. The term is also used to refer to wormhole links between interstellar-separated dyson nodes.
