Metric Engineering

Look at all the stars

Also known as space-time engineering, metric engineering involves the manipulation of the structure of space-time itself. Only transapient entities such as the so-called AI Gods, are capable of producing and controlling such technologies, but their production forms the basis for much of Terragen civilization. Neither the Known Net nor the Nexus, the very cornerstones of the Sephirotic empires, could exist without the use of metric engineering.

    The higher-dimension space within which the brane which defines our universe is imbedded.

    Semi-mythical godtech device capable of exploiting wormholes displaced globally in time for excess processing power.
  • CTC Wormhole  - Text by Anders Sandberg
    A wormhole that forms part of a loop of wormholes enabling a closed timelike curve (CTC). Such wormholes lose stability and cease to function. For this reason wormhole networks must be arranged with care.
  • 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.

    The common term for averaged null energy condition (ANEC)-violating negative energy, also sometimes known as phantom energy.

    Space-time catapult pair used for rapid transport of cargo and passengers between the primary wormhole pairs of a Relay system.

  • 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.

    A power generation system using a minute black hole and space-time metric technology.

    System using Metric Technology that rapidly transports spacecraft across the Wormhole Nexus and Godweb.
  • 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.
  • 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.

    The study of the physics of time.

  • 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.
  • Void Bubble  - Text by Adam Getchell and Todd Drashner
    A warp bubble is a region of space time enclosed in a fold, or bubble, of highly curved space. By expanding the space time metric behind the bubble and contracting the metric in front, the bubble can be made to move without the use of propellant mass.
