| | #REDIRECT [[Propulsion in the Re-imagined Series#Faster-Than-Light travel]] |
| | |
| Acronym for <u>F</u>aster-<u>t</u>han-<u>L</u>ight. This is a term used to describe a means of astral propulsion utilized by the [[Cylons]] and the [[Colonials]].
| |
| | |
| The FTL drive makes interstellar travel possible for both the [[Colonials]] and [[Cylons]]. No longer confined to their own home solar system, the Cylons managed to avoid Colonial interference for 40 years after the [[Cylon War]] and establish their own homeworld. However, not all ships -- from small to large -- are outfitted with these drives. ([[Mini-Series]]) Likely because of the cost involved, energy and fiscally speaking.
| |
| | |
| The technology behind FTL systems is such that, providing the relevant data is known, ships can jump with a high degree of accuracy, allowing ships to rendezvous in space and even "park" in a synchronous orbit directly above a given point on a planet's surface ([[Mini-Series]], it even enables vessels to arrive in crowded areas, such as the middle of an asteroid field, without the risk of collision and damage ([[The Hand of God]]).
| |
| | |
| == Colonial Limitations ==
| |
| | |
| * Colonial FTL systems are not small-scale, and cannot be installed into vehicles such as the [[Viper]]. They can, however, be used on the [[Raptor]], which is limited to brief, short-distance jumps. ([[Mini-Series]]).
| |
| * Colonial FTL systems cannot be used multiple times over a long period of time, for they are prone to breakdown after excessive, repetitive use. ([[33]])
| |
| * The wormholes generated by Colonial drive systems are limited in size; this defines the maximum size to which a colonial vessel can be built (hence the need for [[Battlestar|battlestars]] to retract their landing pods and reduce their overall cross-section prior to a jump ([[Mini-Series]], [[33]], etc.).
| |
| * Colonial FTL systems appear to have been developed to meet the needs of jumping between the [[Twelve Colonies]] and their attendant [[Cyrannus|star system(s)]]. As such, Colonial FTL capabilities have defined limits, referred to as the [[Red Line]], obeyond which jumps may not be possible / could result in damage to a vessel's drive system / lead to navigational inaccuracies that might put the ship at risk
| |
| | |
| == Cylon Advantage ==
| |
| | |
| * Cylon FTL systems can be manufactured on a smaller scale to their Colonial equivalent, thus allowing the [[Cylon Raider]] to be outfitted with an FTL drive. ([[Mini-Series]]).
| |
| * Cylon FTL drive systems are far more efficient than their Colonial equivalent. Tests with the Raider captured by the [[Battlestar]] ''[[Galactica]]'' ([[You Can't Go Home Again]]) demonstrated that the drive could enable the Raider to jump directly from the vicinity of [[Kobol]] back to [[Caprica]] ([[Kobol's Last Gleaming, Part I]]) - a jump completed by Lieutenant [[Thrace, Kara|Kara "Starbuck" Thrace]] during her search for the [[Arrow of Apollo]] ([[Kobol's Last Gleaming, Part II]]).
| |
| * The extreme ranges over which Cylon vessels can jump would indicate that Cylon nagivation systems are far better integrated with their FTL system to enable such long-distance jumps to be accurately plotted.
| |
| * Given that the Cylons left Colonial space to find their own planet, it is possible that their longer-range FTL capability was created in response to a desire to be able to cover the distance between their adoptive homeworld and those of the [[Twelve Colonies]] with a single jump.

| ==Background to FTL in New BSG==
| |
| In establishing the series the creators of the [[Re-imagined|new Battlestar Galactica]] determined to keep everything within the show very "[[Naturalistic science fiction|natural]]". This means steering away from the standard clichés of television science-fiction: no bumpy-head aliens, no remarkable technology such as matter/anti-matter conversion, etc. So how is the concept of faster-than-light travel possible within this precept?
| |
| | |
| ===Underpinning Theories===
| |
| | |
| [[Image:Wormhole-demo.png|thumb|FTL: "Folding Space" (credit: Wikipedia)]]
| |
| The FTL drive technology used within the [[Re-imagined|new Battlestar Galactica]] appears to be based on the use of [http://en.wikipedia.org/wiki/Superstring_theory Superstring Theory] and [http://en.wikipedia.org/wiki/M-Theory M-Theory] that essentially enable the "jump drive" systems to "fold" space, reducing the distance between any two points by creating a "corridor" through space that links them together (essentially forming a wormhole, or Einstein-Rosen Bridge.
| |
| | |
| The use of such Wormholes is based on the tenet that space is curved. Hence the term "[http://en.wikipedia.org/wiki/Wormhole wormhole]", which arises from the analogy that space can be seen as an apple. A worm can travel from one side of the apple to the other in two ways:
| |
| * By crawling over the surface, or
| |
| * By burrowing through the apple (creating a "wormhole").
| |
| Obviously, the second option is considerably shorter than the first.
| |
| | |
| ===Relativistic Acceleration===
| |
| A key point concerning the use of wormholes within the new Battlestar Galactica, is that they do not break the fundamental limiting factor of our universe: the speed of light. Vessels in the new Battlestar Galactica series do not accelerate to faster-than-light velocities. Rather, they use the wormhole to reduce the distance to theit destination, thus giving the <i>impression</i> of faster-than-light travel.
| |
| | |
| This is the reason why FTL jumps are virtually instantaneous within episodes (e.g.[[33]]). It also means that the only <i>direct</i> form of propulsion available for vessels is generated by their [[Sublight Propulsion|sublight drive systems]]. In turn, this is why vessels exiting from a jump are seen to be travelling at the same velocity as when they committed to the jump ([[Mini-Series]], [[33]], [[The Hand of God]], etc.)
| |
| | |
| ===Feasibility===
| |
| While the use of wormholes in this manner is not currently possible, work is progressing on string, superstring and M-Theory which may make the creation of wormholes possible in the future. As such, the use of such systems again meets one of the stated desires of the the producers of the new Battlestar Galactica: not to rely on the "traditional" trappings of science-fiction that require exotic science and technology. Theoretical physicist [http://en.wikipedia.org/wiki/Kip_Thorne Kip Thorne] has carried out extensive research into wormholes, and helped develop a scientifically-consistent means of wormhole travel used by [http://en.wikipedia.org/wiki/Carl_Sagan Carl Sagan] in his novel [http://en.wikipedia.org/wiki/Contact_%28novel%29 "Contact"] which bears a remarkable similarity to the technology employed within Battlestar Galactica.

| ==Notes==
| |
| # In the [[Mini-Series]], the impression is given that an FTL jump hasn't taken place in some 20 years. Given the preponderance of ships with FTL drives (some 63 comprising the suriving Colonial fleet alone ([[33]]), this seems unlikely for the following reaons:
| |
| ## Why build ships with the added mass and complexity of FTL systems if they are not going to be used?
| |
| ## Two decades puts the cessation mid-way between the [[Cylon War]] and present-day times, so the reason for halting FTL jumps cannot be related to any fear that FTL systems may be infiltrated by Cylons
| |
| # It is therefore probable that in making the comment in the [[Mini-Series]], [[Tigh, Saul|Colonel Tigh]] was referring to the last time the ''[[Galactica]]'' herself made an FTL jump.
