Sundala Starzone Setting Mechanics

Average Sub-Light Velocities


These are the average speeds and acceleration curves employed in setting, mostly determined by the efficiencies of the various propulsion systems employed by the myriad of factions. Speeds can be exceeded but usually in a specific context as excess fuel will be used or the various means of lowering the effects of G-forces may not be able to prevent issues beyond the framework presented below.

Civilian Spec Drive

  • Average Mean Velocity
    0.0012 (0.12%) C
    (359 Km/s or 17 Minutes 50 Seconds from the earth to the moon)

Military Spec Drive

  • Average Mean Velocity
    0.0032 (0.32%) C
    (960 Km/s or 6 Minutes 40 Seconds from the earth to the moon)

Small Craft Drive

  • Average Mean Velocity
    0.0045 (0.45%) C
    (1,349 Km/s or 4 Minutes 44 Seconds from the earth to the moon)

Munitions

Roth-Fujita Jump Drive FTL Drive


The Roth-Fujita Singularity Jump Drive (often simply called the Jump Drive for shorthand) is a superluminal propulsion system designed by humanity after the long term study of abandoned fragments of ancient Ozymandian alien technology - mostly consisting of inactive derelict trans-light gates and the occasional fragment of a vessel found scattered across the reaches of the Sundala Starzone.

Core Mechanism

The drive generates a controlled singularity forward of the vessel, the tear in space time linking to the destination point derived from the vessel's navigational calculations. Gravitational influence and a stability field will then draw the singularity over the vessel, shunting it to it's destination instantaneously.

  • External Observation: A brilliant sphere of light forms at the bow, expands to envelop the vessel from front to back, and then vanishes in a burst of exotic particles and light, leaving no other trace.
  • Internal Observation: No conventional sensation of momentum or acceleration occurs, the transition to internal observers is near instant with respect to the ships internal frame of reference.

Unlike the Alcubierre drives utilized by non-Sundala races, the Roth-Fujita Jump Drive and simliar systems are not affected by celestial bodies between their initiation and destination points due to the nature of the drive 'folding space' rather than traveling through it.

Power Source

Antimatter capacitors are employed to feed the massive prompt energy requirements of the fold drive and its short lived generated singularity.

Derived from the abandoned fragments of Ozymandian technology, most were in the form of derelict gates and vessels seemingly left behind long before mankind's arrival to the Sundala Starzone. The jump drive or Roth-Fujita Translight Singularity Drive is a superluminal method of travel that involves the vessel essentially forming singularity and then drawing the vessel through it. To an outside observer the vessel seemingly produces a ball of light off its bow before drawing it over itself and vanishing in a flash of exotic particles. For the vessel there is actually no momentum, merely a transition through a 'hole' in space time. Unlike Alcubierre style drives they are not affected by celestial bodies between the origin and destination points as they fold space to reach their destination.

Antimatter, due to its prompt and massive energy impulse, is the primary method of powering the drive. The mass of the object employing the jump drive as well as the distance to be traveled determines the amount of power and thus antimatter mass needed to perform he jump. Additionally calculations must be carried out by the craft's navigation systems to precisely place both the entry and the exit point of the singularity. The greater the distance, the greater the time needed in order to perform these calculations. Charting and pre-existing knowledge of the destination can dramatically reduce the amount of computational time required.

Due to the lack of the need for massive fusion systems to power the drive they can be mounted on craft as small as shuttles and fighters.

Superluminal Travel Methods


Fixed Position FTL 'The Gates'

  • Marii Translight Gate System
    • All gates are linked to the same bulk space so one can enter and exit anywhere in the system, gates are also 'closer' on the bulkspace side of the gates and thus ships have faster travel time.
    • Created by the Marii Race hundreds of millions of years ago.
  • Kylev-Muldoon Gate System
    • Kylev-Muldoon Gates are all 'paired' systems with an entry point and exit point and do not share bulkspace with other KM Gates. Thus a ship must exit at each system along the network slowing travel times.
    • Created by humanity as a rough attempt at our own point to point FTL gate system.
  • The gates link to bulk space 'tunnels' within an isolated higher pocket dimension.
  • Gates essentially encapsulate ships in a bubble of normal dimensional space and dispatch it toward the receiving gate they signaled for.
  • Due to the far shorter distances between the gates from within the bulk space travel time which would take normal FTL methods days can be done in hours.
  • Ships within bulkspace are isolated in their own pockets of normal dimensional space and cannot interact with other vessels transiting within the bulk.

  • Concentrated Regions of Dark Matter
    Areas where dark matter has congealed and condensed into dense clouds, effectively blocking all forms of FTL. The gates bypass this restriction.

Superluminal Communications


Riemann-Kennedy Mechanism 'RK Box'

  • Effectively a microscopic FTL gate that links to a series of pre-selected micro bulkspace dimensions, this allows radio waves to travel across the space between the RK boxes at near instantaneous speed.
  • The synced RK Boxes must be travelling at a predictable speed and direction or the connection to the bulkspace will destabilize.
  • RK Boxes must have a shared bulkspace 'frequency' in order to sync.
  • Range is fundamentally unlimited.

Shimura-Jost Array 'SJ Device'

  • An FTL Radio more or less.
