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.

Class of relativistic warship designed to transport and support smaller combat craft over interstellar distances.
- 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.

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.

Spacecraft containing, and propelled by, miniature space-time warps known as Void Bubbles.

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

That part of the Nexus and the Known Net which is used by archailects (SI:4 and above).
- Grazer - 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.
- 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.
- Kuranaba Gate - Text by M. Alan Kazlev
Originally 75 meter, now 150 meter gauge Wormhole connecting Kuranaba and Big Tor. There is talk of this being further upgraded to 250 meters.
- 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.
- Metric Bomb - Text by Todd Drashner
Godtech weapon capable of destroying planets or stars with virtually no warning.

Generic term for the size scale at which the nature and behaviour of matter and energy is determined by quantum effects.
- Reactionless Drives - Text by Todd Drashner and Adam Getchell
Propulsion without reaction mass.
- Reality Intratextualization Project - Text by Anders Sandberg
On ancient Old Earth (Information Age), the ailogist Hans Moravec had pointed out that there were an infinite number of nontrivial ways of transforming the actual universe into a representation following its own laws, where each event in the real universe would be represented but in a different context.
- 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 microguage 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.
- Spacetime Catapult - Text by Todd Drashner
Large, even megascale structure which uses magmatter accelerators to launch cargo to relativistic or near-relativistic velocity. The cost of construction and maintenance is extremely high, meaning only fairly developed and rich systems that are not part of the nexus can afford them.
- Stargate - Text by Stephen Inniss and Steve Bowers
Alternative term for a traversable wormhole.
- 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.

- Vega - Text by Steve Bowers

- 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.

- 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 archailect architecture. The term is also used to refer to wormhole links between interstellar-separated dyson nodes.
