A &#039;&#039;&#039;Resurrection Ship&#039;&#039;&#039; is a large, slim vessel specifically dedicated to the &amp;quot;[[Resurrection (RDM)|resurrection]]&amp;quot; of [[humanoid Cylon]]s who are killed or lost to the Cylon fleet ([[TRS]]: &amp;quot;[[Resurrection Ship, Part I]]&amp;quot;). &lt;br /&gt;
&lt;br /&gt;
== Design == &lt;br /&gt;
[[Image:Res Ship Int.jpg|thumb|left|Extra Cylon copies are seen behind the large glass facades.]]&lt;br /&gt;
The Resurrection Ship is a long, slim vessel composed of a large glass facade underneath a large metal superstructure sectioned off into individual frames. Underneath the glass, are stored the extra Cylon bodies the ship carries, maintained by artificial means until its ready for a new &amp;quot;host&amp;quot; consciousness. The aft end of the ship contains a large antenna, the FTL and sublight engines.&lt;br /&gt;
&lt;br /&gt;
The interior matches with the Cylon basestar: Spartan metallic rooms with square, dim, light fixtures placed on the walls and ceilings. The rooms are occupied by rebirthing tanks, in which a spare body is placed, thus beginning the downloading and resurrection process ([[TRS]]: &amp;quot;[[Rapture]]&amp;quot;).&lt;br /&gt;
&lt;br /&gt;
The ship carries no offensive or defensive armaments of any kind, and must rely on the bulk of the Cylon fleet for defense. If left alone, Resurrections Ships are completely vulnerable to even the smallest of attacks ([[TRS]]: &amp;quot;[[Resurrection Ship, Part I]]&amp;quot;).&lt;br /&gt;
&lt;br /&gt;
== History ==&lt;br /&gt;
[[Image:RS Algae.jpg|thumb|left|A Resurrection Ship in the vicinity of the [[Algae planet]].]]&lt;br /&gt;
The ship&#039;s existence is first discovered by surviving colonials by a Raptor scout detached from the battlestar [[Pegasus (RDM)|&#039;&#039;Pegasus&#039;&#039;]] (BS 62) two to three months following the [[Fall of the Twelve Colonies]], after it began tracking a large Cylon fleet jumping to systems with natural resources. Upon further examination, this Cylon fleet was found to be tracking a large Colonial fleet, led by the battlestar [[Galactica (RDM)|&#039;&#039;Galactica&#039;&#039;]] (BS 75). Following a series of internal struggles, the Colonials utilize both battlestars, and [[Battle of the Resurrection Ship|attack the Cylon fleet]], destroying both basestar escorts and the Resurrection Ship ([[TRS]]: &amp;quot;[[Resurrection Ship, Part II]]&amp;quot;). Despite the Colonial victory, the celebration is short lived - this Resurrection Ship was just one among many, and while the destruction of the ship put the Cylons on notice, it wasn&#039;t long before another was moved up in its place ([[TRS]]: &amp;quot;[[Lay Down Your Burdens, Part II]]&amp;quot;). Since the Colonial attack, the Cylons allot more basestars to its defense ([[TRS]]: &amp;quot;[[Torn]]&amp;quot;).&lt;br /&gt;
&lt;br /&gt;
Following the outbreak of the Cylon Civil War, all constructed Resurrection Ships fall under the control of [[John Cavil]]&#039;s loyalist forces. They are hidden out of downloading range when he moves to attack the rebel fleet ([[TRS]]: &amp;quot;[[The Ties That Bind]]&amp;quot;). [[Rebel basestar|One basestar]] survives, and as retribution, seeks to destroy the main [[Resurrection Hub]] - the central control facility that mediates all Resurrection Ships. Without the Hub operational, Resurrection Ships would cease to function. The [[Battle of the Resurrection Hub|attack]] is successful, and Cylon resurrection is destroyed along with the Hub ([[TRS]]: &amp;quot;[[The Hub]]&amp;quot;). Following the battle, the Resurrection Ships disappear from view, and are presumed to have been staged in a safe location, while the remaining Cylon loyalists attempt to rebuild resurrection technology following the kidnapping of the child [[Hera Agathon]] from &#039;&#039;Galactica&#039;&#039;&amp;lt;nowiki&amp;gt;&#039;s&amp;lt;/nowiki&amp;gt; fleet ([[TRS]]: &amp;quot;[[Someone To Watch Over Me]]&amp;quot;). However, the Colonials strike back at the Cylons, attacking the [[The Colony|Colony]] where Cavil took the child. &#039;&#039;Galactica&#039;&#039; is successful in rescuing the child, thus preventing the rebuilding of resurrection technology. By complete chance, the Colony is [[Battle of the Colony|destroyed]] shortly after, taking along with it the Cylon&#039;s only chances of regaining resurrection abilities. What becomes of the Resurrection Ships after this point, is unknown ([[TRS]]: &amp;quot;[[Daybreak, Part II]]).&lt;br /&gt;
&lt;br /&gt;
&amp;lt;div style=&amp;quot;clear:both;&amp;quot;&amp;gt;&amp;lt;/div&amp;gt;         &lt;br /&gt;
&lt;br /&gt;
== Notes ==&lt;br /&gt;
*The Resurrection Ship bears a strong resemblance to the United States [http://www.greatbuildings.com/buildings/Air_Force_Academy_Chapel.html Air Force Academy chapel].&lt;br /&gt;
*Given that without a Resurrection Ship the Cylons face permanent death even before the Hub&#039;s destruction ([[The Hub]]), it seems that the Resurrection ships work as a kind of  &#039;booster&#039; for the range of the Resurrection Hub, suggesting that the Hub&#039;s effective download range is limited without its accompanying ships.  Given that the Hub contains birthing tanks, it acts as a kind of Resurrection Ship itself also.&lt;br /&gt;
*Before Baltar briefs Adama and Cain on its true function, Cain speculates that it might be a command ship, while Adama states that it might be a Raider factory. While it is not stated how Raider personalities are resurrected, the caution that the [[Scar|Cylons exhibit after the destruction of the Resurrection Ship]] suggests that they support the Raiders in some fashion.&lt;br /&gt;

&lt;div&gt;&#039;&#039;&#039;&amp;quot;Actual&amp;quot;&#039;&#039;&#039; is the [[wireless]] callsign for the commanding officer, borrowed from the real-world communications term for the officer-in-charge (e.g. the commander of a military vessel, task force or unit). &lt;br /&gt;
&lt;br /&gt;
It is used to distinguish the commanding officer from other personnel who may use the communications channel, without resorting to a code name or other identification. It is frequently used when sensitive information needs to be communicated directly to the officer-in-charge or when a direct and urgent order must be rendered.&lt;br /&gt;
&lt;br /&gt;
Example: A pilot from battlestar &#039;&#039;Pacifica&#039;&#039;, callsign &amp;quot;Joker&amp;quot;, is ordered to engage a target.&lt;br /&gt;
&lt;br /&gt;
: &#039;&#039;&#039;Pacifica&#039;&#039;&#039;: Joker, Pacifica.  Engage the unidentified craft, weapons free.&lt;br /&gt;
: &#039;&#039;&#039;Pilot&#039;&#039;&#039;: Pacifica, Joker. Confirm.&lt;br /&gt;
: &#039;&#039;&#039;Pacifica&#039;&#039;&#039;: Joker, Pacifica Actual.  Execute the order.&lt;br /&gt;
&lt;br /&gt;
When communicating over wireless aboard &#039;&#039;[[Galactica (RDM)|Galactica]]&#039;&#039;, [[William Adama]] is &amp;quot;Galactica actual&amp;quot;. &lt;br /&gt;

&lt;br /&gt;
== Summary ==&lt;br /&gt;
&lt;br /&gt;
A viper squadron led by Troy and Dillon chases Xavier through space. Suddenly, three Cylon fighters attack them. During the battle, one viper is destroyed and Dillon&#039;s viper is severely damaged. The entire squadron except for Troy is forced to return to the Galactica.&lt;br /&gt;
&lt;br /&gt;
Troy continues to pursue Xavier who is attacked by another Cylon raider. Then the Ship of Lights appears (from the BG episode War Of The Gods). Its high-pitched whine causes Troy to fall unconscious, and his ship is captured. Meanwhile, Xaviar activates his time-travel device and enters a time warp. The Cylon raider follwing him is caught in the time warp and is pulled into it as well.&lt;br /&gt;
&lt;br /&gt;
On the Galactica, Dr. Zee and Adama see images of what has happened to Xaviar and the Cylon raider. Because Troy&#039;s viper is gone, they assume he had been killed. Meanwhile, Troy wakes up on the Ship of Lights in disbelief. He is welcomed by Lt. Starbuck, who was lost and believed dead fourteen years earlier.&lt;br /&gt;
&lt;br /&gt;
Dillon lands on the Galactica and is told Troy is dead. He puts his grief aside to work on the problem with Xavier. He goes to Earth to get Jamie and takes her to the Galactica. While mourning the death of their friend, the two kiss. On the Ship Of Lights, Troy is confused. Starbuck says that he&#039;s going to help him stop Xaviar. He tells Troy that he (Starbuck) didn&#039;t die. He merely evolved to another plane of existence. Starbuck says that this is the ship of the Guardians of the Universe, the beings who gave the Colonials the coordinates to Earth many years back (in War of the Gods).&lt;br /&gt;
&lt;br /&gt;
Jamie and Dillon prepare to go 2,600 years into the Earth&#039;s past. Troy asks what happened to Apollo, his father, but Starbuck says there is no time to discuss it. Moments later, Troy wakes up on his viper, activates his time-warp synthesizer, and goes into the past.&lt;br /&gt;
&lt;br /&gt;
Xaviar arrives in the [[wikipedia:Chaldea|Chaldea]] desert in 592 B.C. followed by the Cylon raider. Seconds later, Troy arrives and gives pursuit. He and Xaviar agree to team together to destroy the Cylon raider.&lt;br /&gt;
&lt;br /&gt;
In the desert below, the people watch the aerial battle with fascination. The Cylon raider is damaged and plummets toward the earth, giving the appearance of a giant wheel spinning in the sky. Xaviar then time-warps into another period. Troy&#039;s viper is also damaged and he crashes.&lt;br /&gt;
&lt;br /&gt;
Dillon and Jamie then arrive and investigate the crashed viper, believing it to be Xavier&#039;s. They are stunned when they see Troy climb out. Before Troy can explain, a damaged Cylon who survived the crash comes at them firing his laser. Troy and Dillon blast him and he falls. As the three are about to destroy what remains of the Cylon raider, the supposedly dead Cylon rises and fires at his ship, causing an explosion which knocks Dillon senseless. Then the Cylon aims at Troy, who can&#039;t fire back because his laser is jammed. Jamie grabs Dillon&#039;s laser and shoots the Cylon, exploding it in a shower of sparks. They then set explosive charges on the Cylon raider and completely incinerate it. They board their vipers and fly into another time-warp and vanish, unaware that they were observed by a man on a sandy knoll.&lt;br /&gt;
&lt;br /&gt;
On the Galactica, Adama and Troy are reunited. Afterwards, Jamie realizes that the Cylon Raider was the &amp;quot;Wheel of Fire&amp;quot; (the famous vision from the Old Testament prophet [[wikipedia:Ezekiel|Ezekiel]]) seen in 592 B.C.&amp;lt;ref&amp;gt;&#039;&#039; Galactic Sci-Fi Television Series Revisited.&#039;&#039; Alpha Control Press, 1995.&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Notes ==&lt;br /&gt;
* This script is the sequel to the classic Galactica 1980 episode [[The Return of Starbuck]]. &lt;br /&gt;
* It is revealed why Angela from &#039;&#039;The Return of Starbuck&#039;&#039; was judging Starbuck. She was testing him to see if he was worthy to become one of the Guardians of the Universe on the Ship of Lights. &lt;br /&gt;
* Troy asks Starbuck what happened to Apollo but is told that there isn&#039;t time to discuss it. Apparently, Apollo&#039;s death was a mystery. &lt;br /&gt;
* Romance begins to develop between Dillon and Jamie. They were only friends in the produced episodes of the series.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;:&#039;&#039;For information on the [[Battlestar Galactica (TOS)|Original Series&#039;]] modes of propulsion, see [[Propulsion (TOS)]].&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
{{RDM science series}}&lt;br /&gt;
In the [[Re-imagined Series]], propulsion systems are powered by fuel refined from [[tylium|tylium ore]]. A ship&#039;s primary propulsion systems, referred to as &amp;quot;sublight engines&amp;quot;, allow it to travel at a slight fraction of the speed of light, which is sufficient to traverse the distances between planets in a solar system in relatively short timeframes.  Most ships in the series also have a secondary system, called a [[Propulsion in the Re-imagined Series#Faster-Than-Light travel|&#039;&#039;&#039;faster-than-light drive&#039;&#039;&#039;]] (or &#039;&#039;&#039;&amp;quot;FTL&amp;quot;&#039;&#039;&#039;), that enables a ship to travel interstellar distances almost instantaneously, by &amp;quot;folding up space&amp;quot; in between the ship and its destination. Since, under normal circumstances, a ship that has used its FTL drive cannot be followed without explicit information about its destination, this technology is used extensively in strategic and tactical manuevers. &lt;br /&gt;
&lt;br /&gt;
==Sublight propulsion==&lt;br /&gt;
&lt;br /&gt;
In the Re-imagined Series, all ships have some manner of sublight flight ability. Sublight propulsion is convenient for intra-solar system travel (such as to or from the planets that comprise the [[The Twelve Colonies (RDM)|Twelve Colonies]]), but cannot be used for travel outside of a solar system as the time to arrive at a destination may exceed the fuel supply of the ship or the lifetime of the crew that fly the ship.&lt;br /&gt;
&lt;br /&gt;
As many of the ships of the [[The Fleet (RDM)|Fleet]] are capable of landing on and taking off from planets, (such as [[New Caprica]]) it is clear that sublight engines work in an atmosphere as well as in space. &#039;&#039;Galactica&#039;&#039; is never seen doing this, and its large mass might prohibit planetary landings altogether, but it employs sublight engines for normal spaceflight. Few of the ships appear to have extremely large propellant tanks as would be required for rocketry as it is presently understood, in spite of having aft-mounted thrusters. This may be explained by the very high energy density of [[tylium]] fuel. Smaller vessels are known to employ rocketry-based [[Navigation in the Re-imagined Series|RCS thrusters]] for maneuvering and small course adjustments.&lt;br /&gt;
&lt;br /&gt;
Vipers are equipped with a thrust reversal system to counteract or arrest their forward momentum ([[The Hand of God (RDM)|The Hand of God]]). No such mechanism exists on capital ships, but such vessels might turn by 180° to decelerate.&lt;br /&gt;
 &lt;br /&gt;
Cylons [[Basestar (RDM)|baseships]] do not have any visible exhaust nozzles or other external structural mechanisms that suggest propulsion ability. It is possible that force fields of the [[Gravity in the Re-imagined Series|artificial gravity]] generators are the source of the sublight propulsion. &lt;br /&gt;
&lt;br /&gt;
Both Colonial ([[Hero]]) and Cylon missiles used in combat appear to be rockets, leaving a trail of gas behind them.&lt;br /&gt;
&lt;br /&gt;
The law of conservation of momentum requires that any propulsion system which adds momentum to a spacecraft or missile in one direction must equal the amount of momentum that is imparted in the opposite direction to something else, as in the example of the controlled combustion of rocket fuel creating thrust in the opposite direction of a ship&#039;s or missile&#039;s movement. &#039;&#039;[[Pegasus]]&#039;&#039;, for example, possesses two very large thrusters on the bow of the ship to counteract the force of the main engines ([[Razor]]). However, many other vessels don&#039;t appear to have such thrusters.&lt;br /&gt;
&lt;br /&gt;
===Relativistic Sublight travel ===&lt;br /&gt;
The [[Thirteenth Tribe (RDM)|Thirteenth Tribe]] did not have jump drive technology, so FTL travel was unavailable to the [[Final Five]] on their voyage from [[Earth (RDM)|Earth]] to the [[Twelve Colonies (RDM)|Twelve Colonies]]. They instead used a sublight drive able to reach relativistic speeds (a substantial fraction of the speed of light.)  The journey took about 2,000 years according to a planetary reference frame, but a more modest (unspecified) number of years in their ship&#039;s reference frame.&lt;br /&gt;
&lt;br /&gt;
==Faster-Than-Light travel==&lt;br /&gt;
[[Image:FTL1.jpg|thumb|&#039;&#039;Galactica&#039;&#039; FTL jump.]]&lt;br /&gt;
&#039;&#039;FTL&#039;&#039; is an abbreviation for &#039;&#039;&#039;F&#039;&#039;&#039;aster-&#039;&#039;&#039;T&#039;&#039;&#039;han-&#039;&#039;&#039;L&#039;&#039;&#039;ight.  The term refers to a means of interstellar propulsion utilized by the [[Cylons (RDM)|Cylons]] and the [[The Twelve Colonies (RDM)|Colonials]]. A common shorthand term for FTL travel is &#039;&#039;&#039;&amp;quot;jumping&amp;quot;&#039;&#039;&#039;, as this  space-folding drive involves making instantaneous &amp;quot;jumps&amp;quot; across vast distances in space.&amp;lt;ref&amp;gt;http://www.scifi.com/battlestar/about/index.php?sub=glossary&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
[[Image:Basestar FTL Jump The Plan.png|thumb|Basestar FTL jump.]]&lt;br /&gt;
&lt;br /&gt;
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 [[Cylon homeworld|home-world]].  However, not all ships &amp;amp;mdash; from small to large &amp;amp;mdash; are outfitted with these drives ([[Miniseries]]). &lt;br /&gt;
&lt;br /&gt;
It is likely that FTL drives are not commonplace on many civilian ships because of the costs involved in using and maintaining the drive and the amount of [[tylium|fuel]] available. For some civilian ships that travel comparatively short distances between some destinations, such as the ill-fated [[Botanical Cruiser]], FTL may simply be impractical or unnecessary.&lt;br /&gt;
&lt;br /&gt;
The technology behind FTL systems is such that, providing the relevant data is known (how that data is acquired, for instance how ships can determine what obstacles are present at their destination, despite never having traveled there before, is not known) ships can jump with a high degree of accuracy, allowing ships to rendezvous in space and even &amp;quot;park&amp;quot; in a synchronous orbit directly above a given point on a planet&#039;s surface ([[Miniseries]]). Proper FTL use even enables vessels to arrive in crowded areas, such as the middle of an asteroid field or other ships, without the risk of collision and damage ([[The Hand of God (RDM)|The Hand of God]]).&lt;br /&gt;
&lt;br /&gt;
[[Image:Ftl_display.jpg|thumb|FTL drive display]]&lt;br /&gt;
&lt;br /&gt;
Little specific information on the technology of an FTL drive has been given in the Miniseries or regular series. We know only that &#039;&#039;Galactica&#039;&#039; has two FTL drives&amp;lt;ref&amp;gt;Dialogue from Colonel [[Saul Tigh|Tigh]] to Lt. [[Felix Gaeta|Gaeta]] instructs the tactical officer to &amp;quot;spin up FTL drives 1 and 2&amp;quot; in the [[Miniseries]].&amp;lt;/ref&amp;gt;, and that other smaller or civilian ships have a single drive. Ships also do not need to be in motion for the FTL drive to work, or at least smaller craft do not need to be, as Raptors during the Battle of the Colony jump directly from Galactica&#039;s starboard flight pod without engaging in forward momentum.&lt;br /&gt;
&lt;br /&gt;
FTL drives on &#039;&#039;Galactica&#039;&#039; are said to be &amp;quot;spun up&amp;quot; in preparation for a jump, contain components such as the &amp;quot;spinner&amp;quot; (&amp;quot;[[The Captain&#039;s Hand]]&amp;quot;) and &amp;quot;spin-sync generator&amp;quot; (&amp;quot;[[Faith]]&amp;quot;) and display a rotational and possibly electromagnetic operation. Until the final-season episode, &amp;quot;[[Blood on the Scales]]&amp;quot;, the expression was theorised by many fans to be either a turn of phrase, or an anachronism dating back to another form of propulsion, much like the use of the term &amp;quot;air&amp;quot; in reference to fighter operations in the vacuum of space (&amp;quot;[[Commander Air Group]]&amp;quot;, &amp;quot;[[Combat Air Patrol]]&amp;quot;, &#039;&#039;inter alia&#039;&#039;) and the real-world use of &amp;quot;sail&amp;quot; and &amp;quot;set sail&amp;quot; in reference to self-propelled vessels.&lt;br /&gt;
&lt;br /&gt;
[[Image:Ftl2.jpg|thumb|&#039;&#039;Galactica&#039;&#039;&#039;s FTL drive.]]&lt;br /&gt;
&lt;br /&gt;
An operational FTL drive was first seen in &amp;quot;Blood on the Scales&amp;quot;, specifically one of &#039;&#039;Galactica&#039;s&#039;&#039; two. Indeed, an assortment of long, thick shafts spin as part of the FTL drive mechanism.  The FTL engine room includes a control terminal for diagnostic and auxilliary control.  In order to prevent Felix Gaeta and his mutineers from jumping &#039;&#039;Galactica&#039;&#039; to an unknown location, former Senior Chief Petty Officer [[Galen Tyrol]] attempted to log into the engine room terminal which refused him access, recognising his duty status as &amp;quot;inactive&amp;quot;.  He was nevertheless able to manually disable the drive by removing a the synchronisation coil.&amp;lt;ref&amp;gt;Part identified in dialogue in &amp;quot;No Exit&amp;quot;.&amp;lt;/ref&amp;gt;  Gaeta made no attempt to use the other FTL drive, indicating either that the other drive was inoperative, the two drives are not entirely independent, that neither drive alone is sufficient to jump the ship, or that Gaeta simply decided that the mutiny and Coup d&#039;état were doomed and futher attempts were pointless.&lt;br /&gt;
&lt;br /&gt;
FTL jump drives can be used &#039;&#039;within&#039;&#039; an atmosphere. This Colonial tactic is used often to evade Cylon detection. While [[Raptor]]s primarily perform these kind of jumps, Admiral [[William Adama]] performs a daring intra-atmosphere jump at approximately 100,000 feet altitude with &#039;&#039;[[Galactica]]&#039;&#039; during the [[Battle of New Caprica]] to evade immediate Cylon detection. The battlestar jumps back to space a few thousand feet above the planet&#039;s surface after its Viper deployment.  When &#039;&#039;Galactica&#039;&#039; jumps, the clouds surrounding it and the re-entry fires consuming its hull are &amp;quot;sucked&amp;quot; into the vacuum created by the sudden loss of volume. A clap of thunder is heard afterward, likely caused by air rushing into the aforementioned vacuum ([[Exodus, Part II]]). A similar phenomenon occurs when &#039;&#039;Pegasus&#039;&#039; jumps from the attack on the [[Scorpion Fleet Shipyards]]; the resulting displacement not only draws in the burning gases from the nearby berthing superstructure, but also defuses two nuclear warheads bound for &#039;&#039;Pegasus&#039;&#039; itself ([[Razor]]).&lt;br /&gt;
&lt;br /&gt;
[[Image:Ftl3.jpg|thumb|&#039;&#039;Galactica&#039;&#039;&#039;s engine room.]]&lt;br /&gt;
&lt;br /&gt;
An area of spatial distortion of some sort is also produced when a ship jumps.  This effect has been observed twice thus far.  Once, when the tylium refinery ship &#039;&#039;[[Hitei Kan]]&#039;&#039; is approached by a pair of Vipers and a Raptor in an effort to quell a mutiny aboard the ship.  The &#039;&#039;Hitei Kan&#039;&#039; unexpectedly jumps and the Vipers and Raptor are repelled away by some force as soon as the ship dematerializes ([[A Disquiet Follows My Soul]]).  The second time this is seen is when a Raptor stolen by [[Sharon Valerii|Sharon &amp;quot;Boomer&amp;quot; Valerii]] executes a jump mere meters away from &#039;&#039;Galactica’s&#039;&#039; hull.  When the Raptor disappears into the jump the section of the hull it was adjacent to is instantaneously indented.  Just prior to that, Col. [[Saul Tigh]] expresses his fears of even greater damage should Valerii jump the Raptor while inside &#039;&#039;Galactica’s&#039;&#039; flight pod ([[Someone to Watch Over Me]]).  During the [[Battle of the Colony]], several Raptors actually do jump within &#039;&#039;Galactica’s&#039;&#039; sealed off starboard flight pod causing significant damage to the landing bay within the pod and most likely contributed to the catastrophic failure of her hull after the battle ([[Daybreak, Part II]]).  It is not clear how this distortion field, which seems to produce effects like a shock wave, also coincides with the known effect of a jump acting as a sort of vacuum, which instead of producing an outwards wave should pull the surrounding space into it. The two effects might occur consecutively, the vacuum effect left in the ship&#039;s wake, then the expelled shock wave, as hangar equipment in the flight pod is seen being pulled towards the vacuum before being expelled outwards.&lt;br /&gt;
&lt;br /&gt;
Later, the Fleet&#039;s FTL drives are upgraded by the Rebel Cylons so they can now travel as far and as fast as a Cylon ship.  Not all ships are apparently upgraded as for some reason, the Raptor Boomer steals lacks the upgraded drive.&lt;br /&gt;
&lt;br /&gt;
=== Limitations of Colonial FTL ===&lt;br /&gt;
&lt;br /&gt;
* The effectiveness of a [[Raptor]]&#039;s FTL is limited to brief, short-distance jumps. Raptors require a sequence of short consecutive FTL &amp;quot;hops&amp;quot; to reach the same destination as a Colonial capital ship with a full-sized FTL drive ([[Miniseries]]).&lt;br /&gt;
* Colonial FTL systems are prone to breakdown after repetitive use over an extended period of time ([[33]]).&lt;br /&gt;
* Colonial FTL systems appear to be a holdover from the [[History of the Twelve Colonies#Exodus|Exodus]] from [[Kobol (RDM)|Kobol]], and their current designs have been developed to meet the needs of jumping between the [[The Twelve Colonies (RDM)|Twelve Colonies]], and their outposts in other star systems. Colonial FTL capabilities are generally limited in effective range compared to Cylon FTL.&lt;br /&gt;
* Colonial FTL computers are prone to glitching, often jumping ships to the wrong coordinates ([[Lay Down Your Burdens, Part I]]).&lt;br /&gt;
* Navigators must be careful to plan FTL jump paths in order to keep a safe distance from planets or other large objects ([[Kobol&#039;s Last Gleaming, Part I]]).&lt;br /&gt;
* &amp;quot;Spooling up&amp;quot; a Colonial FTL drive takes at least 20 minutes when the drive has been offline ([[Crossroads Part II]]). Because of this, when ships enter dangerous situations, they keep their FTL drives &amp;quot;spun up&amp;quot;. Drives cannot be kept spun up indefinitely, as system crashes or serious damage to the drive will occur. A &amp;quot;cooldown&amp;quot; time is required after a jump for new jump calculations, so a ship that has jumped into a new location cannot jump to another location for a brief period of time.&lt;br /&gt;
* Colonial capital ships (at least older ones of the Galactica type) require the flight pods to retract before a jump, prolonging jump prep time. Should the ship jump with extended pods, serious structural damage can occur.&lt;br /&gt;
&lt;br /&gt;
Colonial FTL performance can be improved, demonstrated when a [[Raptor]] is successfully refitted by a team apparently led by Lieutenant [[Felix Gaeta]] with the navigational computer from a captured [[Heavy Raider]] (presumably the one used by [[Kara Thrace]] to return from Caprica in &amp;quot;[[Home, Part I]]&amp;quot;) and, with the cooperation of a [[Sharon Agathon|Number Eight]], is used to navigate a squadron of Raptors back to Caprica on a rescue mission to retrieve a [[Caprica Resistance|group of resistance fighters]] ([[Lay Down Your Burdens, Part I]]). A massive distance that would have taken Galactica 241 jumps one way (~482 jumps total), the Raptor squadron does in only 20 (10 to Caprica, 10 back).&lt;br /&gt;
&lt;br /&gt;
Colonial FTL computers can be affected by highly-charged sub-atomic particles, corrupting their calculations and possibly causing a jump beyond the [[Red Line]], as in the case of [[Raptor 718]] ([[The Face of the Enemy]], Episode 2).&lt;br /&gt;
&lt;br /&gt;
The FTL drive apparently puts significant strain on a ship&#039;s structure.  &#039;&#039;Galactica&#039;&#039; has substantial cracks in her hull adjacent to the FTL drive which Tyrol disabled. ([[Blood on the Scales]])  While discussing structural repairs with Adm. Adama, Tyrol asks him not to jump the ship for a while, whilst his crews upgrade the structure. ([[No Exit]])&lt;br /&gt;
&lt;br /&gt;
FTL jumps can apparently induce nausea or discomfort in some people, such as [[Cally Henderson]] ([[Miniseries, Night 2]], &amp;quot;[[Kobol&#039;s Last Gleaming, Part I]]&amp;quot;).&lt;br /&gt;
&lt;br /&gt;
=== Cylon Advantages in FTL ===&lt;br /&gt;
&lt;br /&gt;
* Cylon FTL systems can be manufactured to be much more compact than their Colonial equivalent, thus allowing the [[Cylon Raider]] to be outfitted with an FTL drive. ([[Miniseries]]).&lt;br /&gt;
* Cylon FTL drive systems are far more efficient than their Colonial equivalent. Tests with the Raider captured by the [[Battlestar]] &#039;&#039;[[Galactica]]&#039;&#039; ([[You Can&#039;t Go Home Again]]) demonstrated that the drive could enable the Raider to jump directly from the vicinity of [[Kobol (RDM)|Kobol]] back to [[The Twelve Colonies (RDM)#Caprica|Caprica]] ([[Kobol&#039;s Last Gleaming, Part I]]) - a jump completed by Lieutenant [[Kara Thrace]] during her search for the [[Arrow of Apollo]] ([[Kobol&#039;s Last Gleaming, Part II]]). This superiority is not from FTL drives themselves, but from the superior Cylon navigation system, resulting in more accurate jump calculations.&lt;br /&gt;
&lt;br /&gt;
Cylon FTL drives are—using the most conservative estimation—three times more effiicent than their Colonial counterparts ([[A Disquiet Follows My Soul]]).  Despite being well-versed in maintaining &#039;&#039;Galactica&#039;&#039;&#039;s two FTL drives and being a [[Final Five]] [[Cylon]], former [[wikipedia:Senior Chief Petty Officer|Senior Chief Petty Officer]] [[Galen Tyrol]] is baffled by Cylon FTL technology and defers to &amp;quot;[[Number Six|Sixes]], [[Number Eight|Sharons]] and maybe even some [[Number Two|Leobens]]&amp;quot; to upgrade Colonial ships&#039; drives. The Fleet later gets the upgrade and the difference can be clearly seen in the jump capabilities: a Raptor stolen by Boomer which for an unknown reason doesn&#039;t have the upgraded drive, takes over a dozen jumps to reach The Colony, but &#039;&#039;Galactica&#039;&#039; and even an upgraded Raptor are able to make the distance that took that Raptor over a dozen jumps, they make in &#039;&#039;one&#039;&#039;.&lt;br /&gt;
&lt;br /&gt;
The Cylons may also be capable of [[faster-than-light communication]].&lt;br /&gt;
&lt;br /&gt;
==FTL jump ranges==&lt;br /&gt;
The range that &#039;&#039;Galactica&#039;&#039; can jump at has never been specified on-screen. However, in a deleted line from the mini-series the jump from Ragnar to the [[Prolmar Sector]] is said to be &amp;quot;30 light-years&amp;quot;&amp;lt;ref&amp;gt;[http://web.archive.org/web/20060517022749/http://www.curemode.com/battlestar/bgarticle26.htm An early draft of the mini-series script]&amp;lt;/ref&amp;gt;, which is way beyond the [[red line]] (maximum safely calculable jump range). This is consistent with Colonel Tigh saying that &#039;&#039;Galactica&#039;&#039; could search every planet within 12 light-years for water before having to jump to another sector altogether ([[Water]]). On this Wiki, producer Bradley Thompson suggested that internally, the writers had been working on the idea the Fleet had been jumping about 5 light-years at a time, although that does not have to have been its maximum range. Finally, on composer Bear McCreary&#039;s blog&amp;lt;ref&amp;gt;[http://www.bearmccreary.com/blog/?p=1760 Bear McCreary&#039;s blog]&amp;lt;/ref&amp;gt;, science advisor Kevin Grazier and producer Bradley Thompson suggested that the final six digits for the jump coordinates Kara interprets from [[the Music]] represent distance in [[SU]]s. 999,999 SUs - the maximum possible distance that can be inputted - would relate to 15.812 Colonial light-years. The distance inputted during the Battle of the Colony is 365,321 SU or 5.77 Colonial light-years, which is presumably the distance from the Colony to Earth ([[Daybreak, Part II]]). There may also be a factoring scale at work, and at close ranges &#039;&#039;Galactica&#039;&#039; appears to be able to jump much more accurately, as demonstrated by its jump from several million kilometers directly into New Caprica&#039;s atmosphere 100,000 feet above the surface ([[Exodus, Part II]]), or a jump of unknown range to within one kilometre of the Colony&#039;s surface ([[Daybreak, Part II]]).&lt;br /&gt;
&lt;br /&gt;
Cylon FTL ranges are considerably larger. At the end of the series, the Fleet&#039;s larger ships have their jump ranges tripled by the installation of Cylon technology ([[A Disquiet Follows My Soul]]). However, during the rescue of Colonial resistance forces from Caprica three years earlier, a Raptor squadron outfitted with a Cylon FTL navigation computer traversed in 10 jumps ([[Lay Down Your Burdens, Part I]]) a distance that &#039;&#039;Galactica&#039;&#039; would have required a minimum of 230 jumps (conservatively) to cross ([[Pegasus (Extended Version)|Pegasus]]), an improvement by a factor of 23.  However, this rescue team was just using the navigation computer to improve their jump calculations.  Another example is how many jumps it ended up taking to reach The Colony.  When Boomer stole a for some reason un-upgraded Raptor, it took her over a dozen jumps to reach The Colony.  But the recon Raptor that was dispatched and even &#039;&#039;Galactica&#039;&#039; herself were able to make that distance in &#039;&#039;one&#039;&#039; jump with their upgraded FTL drives.  Lee Adama even specificly said that The Colony was in &#039;&#039;Galactica&#039;s&#039;&#039; FTL range which it wouldn&#039;t have been before with the un-upgraded drive given Boomer&#039;s journey there.  With the upgraded drives, Tyrol said that the efficency of the Fleet&#039;s jump drive would be trippled and give them a much longer jump range which they believed was key to finding a new world for humanity to settle on.  Cylon FTL&#039;s were so complicated that even Tyrol didn&#039;t understand them fully and said they were going to need rebel Cylons just to do the upgrades.&lt;br /&gt;
&lt;br /&gt;
==Background to FTL in the Re-imagined Series==&lt;br /&gt;
&lt;br /&gt;
{{Plausible speculation}}&lt;br /&gt;
&lt;br /&gt;
In establishing the series the creators of the [[Battlestar Galactica (RDM)|Re-imagined Series]] determined to keep everything within the show very &amp;quot;[[Naturalistic science fiction|natural]]&amp;quot;. 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?&lt;br /&gt;
&lt;br /&gt;
===Underpinning Theories===&lt;br /&gt;
&lt;br /&gt;
[[Image:Wormhole-demo.png|thumb|FTL: &amp;quot;Folding Space&amp;quot;]]&lt;br /&gt;
The FTL drive technology used within the Re-imagined Series might be based on the use of [[Wikipedia:Superstring Theory|Superstring Theory]] and [[Wikipedia:M-Theory|M-Theory]] that essentially enable the &amp;quot;jump drive&amp;quot; systems to &amp;quot;fold&amp;quot; space, reducing the distance between any two points by creating a &amp;quot;corridor&amp;quot; through space that links them together (essentially forming a wormhole, or Einstein-Rosen Bridge). Such &amp;quot;corridors&amp;quot; are allowed by the general theory of relativity; what [[Wikipedia:M-Theory|M-Theory]] does is provide a way to change the topology of space-time dynamically.&lt;br /&gt;
&lt;br /&gt;
The use of such wormholes is based on the tenet that space is curved. Hence the term &amp;quot;[[Wikipedia:Wormhole|wormhole]]&amp;quot;, 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:&lt;br /&gt;
* By crawling over the surface, or&lt;br /&gt;
* By burrowing through the apple (creating a &amp;quot;wormhole&amp;quot;).&lt;br /&gt;
Obviously, the second option is considerably shorter than the first.&lt;br /&gt;
&lt;br /&gt;
===Relativistic Acceleration===&lt;br /&gt;
A key point concerning the use of wormholes within the new &#039;&#039;Battlestar Galactica&#039;&#039; is that they do not break the fundamental limiting factor of our universe: the speed of light. Vessels in &#039;&#039;Battlestar Galactica&#039;&#039; do not accelerate to faster-than-light velocities. Rather, they use the wormhole to reduce the distance to their destination, thus giving the &#039;&#039;impression&#039;&#039; of faster-than-light travel. &lt;br /&gt;
&lt;br /&gt;
However, the FTL jumps in the series do allow information to be sent faster than light can send it, which results in a violation of causality within the special theory of relativity.  (ie. If event A comes before B from one viewpoint, there will be other equally valid viewpoints where event B takes place before A.) Causality is not violated by FTL  in a universe that has a special fixed reference frame, however this contradicts current understanding.&lt;br /&gt;
&lt;br /&gt;
This is the reason why FTL jumps are virtually instantaneous within episodes. It also means that the only &#039;&#039;direct&#039;&#039; form of propulsion available for vessels is generated by their [[Sublight Propulsion|sublight drive systems]]&amp;lt;ref&amp;gt;In turn, this is why vessels exiting from a jump are traveling at the same velocity as when they committed to the jump ([[Miniseries]], &amp;quot;[[33]]&amp;quot;, &amp;quot;[[The Hand of God (RDM)|The Hand of God]]&amp;quot; and other episodes).&amp;lt;/ref&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
===Feasibility===&lt;br /&gt;
While the use of wormholes in this manner is not currently possible, work is progressing on superstring and M-Theory which may make the creation of wormholes possible in the future. The limiting factor is the ability to generate negative energy densities, which are allowed (though severely restricted) by quantum mechanics. As such, the use of such systems again meets one of the stated desires of the the producers of &#039;&#039;Battlestar Galactica&#039;&#039;: not to rely on the &amp;quot;traditional&amp;quot; trappings of science-fiction that require exotic science and technology. Theoretical physicist [[Wikipedia:Kip Thorne|Kip Thorne]] has carried out extensive research into wormholes, and helped develop a scientifically-consistent means of wormhole travel used by [[Wikipedia:Carl Sagan|Carl Sagan]] in his novel [[Wikipedia:Contact (novel)|&amp;quot;Contact&amp;quot;]] which bears a remarkable similarity to the technology employed within &#039;&#039;Battlestar Galactica&#039;&#039;.&lt;br /&gt;
