Talk:Faster-than-light communication/Archive 1

Is it really FTL?

It should be noted that just because the Cylons can transmit signals over long distances, that doesn't necessarily mean those signals travel faster than light. A sufficiently strong signal could (in theory) travel very long distances, especially if the Cylons have set up amplifiers at strategic points in space. Only when the time it takes for the signal to arrive is very short can we assume it's FTL. I personally think very few of the examples are FTL communication:

(Note: 1 AU = 150 million kilometers, the average distance between the Earth and the sun)

• Tracking the Olympic Carrier in "33"
  • A radio signal can travel 594 million kilometers (~4 AU) in 33 minutes, which is less than the distance between Jupiter and the sun (~5 AU), and not nearly the distance between Pluto and the sun (~39 AU). Since the Fleet has shown to be able to jump from one system to the next, it's likely it did just that during the jump chase. This means the tracking on the Olympic Carrier was either an FTL signal, or the ship transmitted the jump coordinates to the Cylons before jumping away.
• Resurrection
  • We know there was indeed a Resurrection Ship following the Fleet, which could even have FTL-capable transmission drones to transmit Boomer's consciousness to Caprica. A Raider may also have been able to do just that.
• D'Anna's documentary
  • Again, a fleet of 2 basestars, associated Raiders (around 1,500) and a Resurrection Ship was following the Colonial Fleet. The Raider D'Anna called in didn't have to come from very far, and the signal could have taken its time. Also, D'Anna says "two Raiders were lost relaying it back to the fleet", which indicates the Raider transmitted the documentary to the Fleet rather than transmitting it to Caprica directly. The Fleet may have dispatched a Raider (plenty of them around, anyway) to jump to Caprica and deliver the documentary there.
• Tracking the tylium ship
  • The Cylons are a long time behind on the Fleet. Note that the Cylons only get to the Fleet's previous location 6 to 12 hours after they've jumped away. Since the Fleet waits 12 hours for the Raptor to rendezvous with them, they only jump every 12 hours minimum. In 12 hours, a signal can travel 13 billion kilometers (=86,4 AU), which is a quite realistic distance to jump.
• Basestar communication
  • Use Raiders as go-betweens. Every basestar has 800 Raiders, so they can spare a few.

I suggest this article be revised to say "possible FTL communication", since there is a plausible alternative in each case. --Catrope^{(Talk to me or e-mail me)} 10:27, 21 March 2007 (CDT)

The article says that the Cylons might have FTL communication. It isn't definite, but just lists possible evidence. It's true that the Cylons could follow the Fleet in a really short distance. But personally I really have the impression that they are hanging several star systems behind.

However, I don't really see any concrete evidence for basestars communicating with each other. And that would the best situation to use Raiders as relays. --Serenity 10:48, 21 March 2007 (CDT)

Nothing more to add here, other than the fact that the only instance of two basestars communicating to each other is "Torn", where the Baltarstar receives communication from the hybrid on the infected basestar at Lion's Head. -- Joe Beaudoin ^{So say we all - Donate} 17:01, 21 March 2007 (CDT)

Yeah, the page is here for people to list examples of potential FTL communications, or definite ones if we find them. FTL via raider-messenger only works to a ship if you know where it is to jump to it. That requires all ships to constantly send raiders back every time they jump to keep central command aware of all their movements. Possible, but pretty difficult. I must admit it is never explained why it takes 33 minutes to re-track the fleet each time. As for 33, recall that the Carrier fails to jump, and 33 minutes later, no Cylons, and this is why they suspect the ship. Had the transmission been pre-jump, there would have been a Cylon attack 33 minutes later, and then no attack 66 minutes later. This strongly suggests the OC is transmitting somehow from the new location. The Cylon resurrection ship can't be just a short distance away all the time -- it's quite big, I would have to believe they would see it (with optical telescopes) as well as detect any radio noise etc. Tracking the mining ship is harder -- there is no way to track a lightspeed signature unless you get very close to it first. Everything we've seen suggests you can't tell where a ship jumped to by watching it jump, else we would have seen double-jumps every time they flee the Cylons etc. There is clearly a distance limit on Cylon FTL and resurrection. The ship in Torn that is infected is many light years away, and IIRC they move ships to stop them from resurrecting. If it were their own isolated resurrection ship for just that tiny area of space at lightspeed, no need to do that. In fact, one wonders how the dead basestar sent word of the infection if its raiders were disabled, except via FTL.--Bradtem 04:29, 22 March 2007 (CDT)

Source?

I've read and re-read the article and the talk page on this topic to make sure I understood its message. The conclusions are possible and is something to note at least in the continuity errors article, just as when the Fleet's size "magically" grew from around 44 ships to 74 ships from the Miniseries to "33". Otherwise, there is no aired source that suggests an FTL component to their communications, only that the writers have not dealt properly with the relativistic effects of communication. This was apparent in the Miniseries during the 2nd missile attack on Colonial One where Galactica and the liner were apparently able to talk in real-time but had to be quite distant. Many many other instances have happened. "Possible" does not equal probable, which is supported by and explained in a marginal or passive fashion by episode events.

Here are two items: Cylon resurrection has yet to explain its communication method and its technology (a wireless transmitter in the body), which, I feel, would need a little insight before determining how fast transmission can go. The second involves D'Anna's documentary. Transmission to a nearby Raider is, of course, cited. How D'Anna did this without tripping off Colonial monitoring (which has also been established in season 1 and 2 episodes) is one thing, but it is more plausible to suggest that such a transmission is picked up by a out-of-range-to-DRADIS Raider after a few minutes (such a transmission would go approximately 200 million miles in about 16 minutes), then it jumped to Caprica with the film. I should add a third: Boomer was killed while a Cylon fleet followed Galactica. After the Fleet left, the slower download transmission of Boomer would get to the Resurrection Ship in it as it entered the same relative space where the battlestar existed as it continued its pursuit of the Fleet. And nothing supports the notion that Boomer was resurrected on anything other than a resurrection ship as yet. Her consciousness, like any other data, could be stored for later reintegration, or she was simply flown to Caprica after resurrection. I don't remember any citation as to where she was. I'm sorry, but there are too many "possibles" here. I like the article's noting of questioning what is going on with this apparent speed of communication. I don't, however, like to draw it into plausibility since FTL communication isn't a plausible just because we say it is here--that's classic fanwanking. These are a series of large gaping continuity errors that we can't explain away like this and should leave be for now except as an error (with maybe asking a question to Bradley). Comments? --Spencerian 08:04, 22 March 2007 (CDT)

I don't think this belongs to "continuity errors". There is nothing that outright says that all communication in the series is bound by the speed of light. It's just what one would assume, and personally I'd prefer it that way.

That a transmission is sent at the SOL and then picked up by the Cylon fleet after jumping into range, still requires that this fleet finds out the position of the rag tag fleet. How can that method be used to track the Fleet if they don't know where they are in the first place? It can explain the resurrection if the position of the Fleet is known, but not the tracking. --Serenity 08:44, 22 March 2007 (CDT)
