The drive as depicted
The re-imagined Battlestar Galactica (miniseries written by Ronald D. Moore and directed by Michael Rymer, first broadcast 8 and 9 December 2003, then four seasons from 2004 to 2009) uses one method of interstellar travel, the jump [HIGH] S3. A ship with an FTL drive vanishes from one place and appears in another with no transit time and no passage through the space between; on screen the ship simply is not there any more, with a flash and a slight visual pinch [HIGH] S3. The miniseries defines the procedure before the first jump to Ragnar Anchorage. Colonel Tigh orders Lieutenant Gaeta to break out the FTL tables and warm up the computers; engineering reports "Spinning up FTL drives one and two"; and Tigh's warning to Adama is that if the calculations are off by even a few degrees "we could end up in the middle of the sun" [HIGH] S1 (miniseries dialogue, read from a fan transcript, S3). Civilian ships without FTL are left behind when the fleet jumps, and the Cylons destroy them [HIGH] S3.
The rules accumulate over the series and are kept. A drive that has been offline needs at least twenty minutes to spool up ("Crossroads, Part II"); ships in danger keep the drive spun up, at the cost of eventual system faults [HIGH] S3. Jumps are limited in distance by the accuracy of the calculation, not by the drive: the further the jump, the larger the error, and the maximum safe distance is the Red Line, which the miniseries has Adama order the fleet across, to the Prolmar Sector, as the only way to lose the Cylons [HIGH] S3. The series bible (an S3 document) puts the reason as a calculation that grows with distance, to the point that a hundred-light-year jump is a century's worth of arithmetic [MED] S3. Cylon navigation computers are much better: a Raptor fitted with a captured Cylon computer makes in ten jumps what took Galactica over two hundred, and the fleet's range triples when the upgrade is fitted ("The Passage" and after) [HIGH] S3. The episode "33" builds an hour of television on a fleet that must jump every thirty-three minutes because the Cylons arrive on that schedule; the drives are shown wearing out under the strain [HIGH] S3. Ships jump from inside an atmosphere in "Exodus, Part II", Galactica dropping to a hundred thousand feet over New Caprica, launching Vipers and jumping out, the departure sucking in the surrounding air with a clap of thunder [HIGH] S3. Fuel is tylium, and its shortage is a season-one plot [HIGH] S3.
What the series never does is say what a jump is. No episode explains the drive, names a field or a geometry, or states whether the ship tunnels, folds or teleports; the fan wiki's account that the ship "folds space" is the wiki's, and the show itself says only that nothing accelerates to light speed [HIGH] S3.
Origin and lineage
Moore's stated aim for the series was naturalistic science fiction: no aliens, no sound in space, ships that move like ships, with the jump drive the one concession [MED] S3. The 1978 original had a lightspeed drive and a very different feel; the 2003 jump is closer to the instant transitions of Starman Jones and the tramline jumps of the Alderson drive, minus their fixed points: a BSG jump goes anywhere within range [MED] S3. No real proposal is named and none was consulted as far as this catalogue can find; the drive is a plot device kept consistent by procedure rather than by physics. The physics cousin, for a device that moves a ship from one place to another with no transit, is still the wormhole of Morris and Thorne 1988; the difference is that Galactica makes its own, on demand, at both ends, which is exactly what CON-2 says cannot be done.
Which loophole, and why
L3, a shortcut with no fixed endpoints. The ship is at one place and then at another, and the series states that nothing exceeds light speed in between. There is no tunnel shown and no other space entered (which would make it L4), so the class is a shortcut of unstated geometry. The cousin is Morris and Thorne 1988, whose bill is negative energy at the throat scaling with its size, mass beyond engineering, a pre-laid route and a time machine once a mouth moves. Galactica pays none of it; its stated cost is arithmetic, and the arithmetic bill (calculation error growing with distance) is a rule with no physics behind it.
The rules it keeps
- Spool-up time. Twenty minutes from cold; drives kept spun up when in danger [HIGH] S3.
- Calculated jumps and the Red Line. A jump needs a plot from tables; error grows with distance; a maximum safe range exists and crossing it is a desperate act ("beyond the Red Line", miniseries) [HIGH] S3.
- No FTL, no escape. Ships without drives are abandoned; the series never cheats by towing them [HIGH] S3.
- Drives wear. "33" and the tylium episodes make fuel and maintenance limits on jumping [HIGH] S3.
- Better computers, longer jumps. The Cylon advantage is stated as navigation, not propulsion [HIGH] S3.
This is F2 by definition: internally consistent rules, applied with unusual discipline, with no physical content. Spool-up is a cooldown, the Red Line is a range cap, and none of it says what the drive does to space.
What it ignores
Everything about what a jump is. In a fleet that jumps as a unit, the ships arrive simultaneously in some frame, and the series never says which; jumps carry information faster than light (a Raptor can jump back with news), and no episode asks what that does to the order of events in a moving frame. There is no preferred frame, no rule of simultaneity and no time loop in four seasons, and the finale's leap of thirty thousand light years to a prehistoric Earth is treated as distance only [HIGH] S3. Absence dated: as of 2026-09-12 no episode addresses the causality of the jump. C-silent. The energy, stability, tidal and topology entries are untouched for the same reason: a drive that is never described cannot be priced.
Constraint scoring
Every entry in the register, one row each, verdict from the fiction vocabulary in GRADING.md, with a note that says where in the work the engagement or rule occurs.
| Constraint | Verdict | Note |
|---|---|---|
| CAU-1 | SILENT | Jumps move ships and news faster than light; no episode asks about the frame in which a Raptor's return precedes its departure. |
| CAU-2 | SILENT | No chronology protection and no time loop to protect against. |
| CAU-3 | SILENT | The drive makes no wormhole with mouths to move; the time-machine construction never arises. |
| CAU-4 | SILENT | Fleet jumps are simultaneous in some frame and the series never names it; there is no stated preferred frame. |
| CAU-5 | N/A | No entanglement signalling; communication is wireless at light speed and by jumping Raptors. |
| ENE-1 | SILENT | The drive's energy is tylium and its cost is fuel; the currency of a shortcut, negative energy density, is never mentioned. |
| ENE-2 | SILENT | That beating light needs negative energy somewhere is never raised. |
| ENE-3 | SILENT | No mechanism is described to which the quantum inequalities could be applied; a ship-sized shortcut opened for an instant would be priced by them and the show says nothing. |
| ENE-4 | N/A | Warp-bubble pocket geometry. |
| ENE-5 | N/A | Not a Natário-class warp metric. |
| ENE-6 | SILENT | No source of negative energy is named. |
| ENE-7 | SILENT | A jump is a shortcut visible from outside in flat space; topological censorship is never touched. |
| CON-1 | N/A | No warp bubble, so no bubble horizon. |
| CON-2 | SILENT | Jumps go to any calculated point with nothing laid in advance, which is the opposite of what CON-2 allows; the series does not raise it. The Red Line is a limit on calculation, not on infrastructure. |
| CON-3 | N/A | No Krasnikov tube. |
| STA-1 | N/A | Warp-bubble instability. |
| STA-2 | SILENT | A jump that connects two points is a wormhole with the throat unstated; nothing is said of what opens or holds it. |
| STA-3 | N/A | No wormhole is converted into a time machine and the geometry is unstated, so no chronology horizon can be identified. |
| HAZ-1 | N/A | Warp deceleration burst. The atmospheric jump in "Exodus, Part II" has a displacement effect, but it is air rushing into a vacated volume, not a particle burst from a bubble wall. |
| HAZ-2 | N/A | Warp-bubble Hawking flux. |
| HAZ-3 | N/A | Nobody crosses a throat; the ship is gone and then present, and no tidal question can arise in a transit that has no interior. |
| LOR-1 | RULE | The series states that ships do not accelerate to light speed and jump instead; the rule removes the object LOR-1 prices. |
| LOR-2 | N/A | No tachyons. |
| LOR-3 | N/A | No signal in a medium. |
| LOR-4 | N/A | Neither the Scharnhorst effect nor the OPERA anomaly bears on a jump. |
| WRP-1 | N/A | Not a warp metric. |
| WRP-2 | N/A | Not a moving shell. |
| WRP-3 | N/A | No positive-energy warp claim. |
| MAN-1 | N/A | No other space is entered; the ship never leaves the manifold on screen and the series never says it does. |
