I phrased it badly. When the U-wing left Jeddek it was in atmosphere, and it is the first time we ever saw a ship jump to hyperspace while in the gravity well of a planet. one of the major plot points of TFA was reverting from hyperspace in the planet's atmosphere to avoid the shields. Thus, it seems not that Gravity wells do not affect hyperspace travel anymor

I was more annoyed with that ship and how it moved it's wings. It moved them forward when it left atmo, as if it needed them to the side to fly in atmosphere. Ok fine, that makes sense, this is a universe with repulsor technology and artificial gravity technology (otherwise nobody would be walking around on those non-rotating ships), but sure, it needs wings to fly. But then when it lands on the new planet it flew to, it keeps the wings forward!! So why the heck do they move?!?! They serve no purpose other than to look cool and make fans go "oooh! it moves the wings!" *fangasm*

As to gravity effecting jumps, I still don't see the problem. All we have been told in the movies, that I can recall, is "Without proper calculations, you could fly right through a star, or bounce too close to a supernova, and that would end your trip real quick wouldn't it?" Nothing that was done in TFA contradicts that as far as I'm concerned. They never said you CAN'T fly close to gravity objects, just that it's a Bad Idea. Remember, the "we pull you out of hyperspace" thing is only in the games/books/etc, which is non-canon. Maybe they did it in Clone Wars, talking about bumping into a gravity well and it pulling them out, but I don't remember. The only time I recall anyone shutting down hyperspace was with a technological device, that messes with hyperspace drives that are close. That's not gravity, that's technology messing with technology.

The fact that Han was jumping into an atmosphere was still incredibly dangerous, because he might slam right into the planet...like what he warned Luke about. But he apparently had "precise calculations", and was an ace pilot.

Yes, real time conversations existed via the Holonet. But before SW:Rebels, The rebellion had no access to instantaneous communication (as far as we knew). If it were possible I think the rebellion would have found a way to make sure the Rebel Strike force lead by Han Solo on the forest moon of Endor had some way of communicating with the Rebel Fleet. Which would have allowed the rebel fleet to hyper in, as soon as the shields were down

How do you know the rebels didn't have access to that type of communication prior to rebels?

Please cite an example in ANH, ESB, or RotJ where the REBELS, or rebellion have faster then light communication

I am not disputing the fact of faster then light communication, i am disputing the fact we did not see the rebellion using it in the movies

Well we don't see them use toilets either, are we going to claim they didn't have plumbing technology either? Or air conditioning? My point is that this tech was presented in the prequels as already being common place. Or at least small scale enough to fit in a freaking fighter. Are you seriously implying that every non Imperial version of that technology suddenly vanished from the galaxy, without a trace, or an engineer that could build it, because he'd been working on it for years?

I hardly think something as common as a Toilet compares to Faster than light communication (AKA Holonet). In the Rebellion, whether they used holes in in the ground, or sonic bidets in Refreshers, it really does not matter.

But tactically, and strategically access to The Holonet is a HUGE deal with Galaxy spanning Civil war. If we are to assume the Empire is oppressive as it is, to me it would be a great tactical benefit if they could restrict or limit faster than light communication to only the Imperial navy and forces. Most sources on wiki and others explain the idea of the Empire Restricting access to the Holonet, or limiting how others could use it. So if access is restricted or limited, how do the Rebellion get around to using it? Except for Writers to be lazy and make things easy for the characters

I certainly could see some Moisture farmer family, going to the nearest space port and paying a fee to use and official Imperial holonet transmitter to see how their son was doing in the Imperial Academy, and wish him a happy birthday. Both sides knowing that it was quite likely the Empire was Evesdropping or recording and later listening to the conversation

Restricting FTL comms to only military use would mean economic suicide.

I imagine an easy solution is that their are multiple holonet systems or more likely they arent a wholey unified system.

Rather I could imagine the holonet being subdivided into sectors or regions of space. The infrastructure may hve additionally been made by many different corporations that used slightly different interface systems that dont effect use by ships for navigation but complicate maintenance and control. So the Empire doesnt have as firm a grasp on it as we would inagine they should.

Plus if the infrastructure of the holonet is hundreds of years old if not millenia then im sure many independent parties are involved especially the further into the outer rim you go.

These arent canon answers but its how I view it in my head as the concept has never been fully realized in the movies or shows.

There are also “pirate” holonet transceivers in the game. I imagine those are used for the most critical/high level rebel communications, but they’re expensive and I imagine that the Empire might be able to find them easily if they are used too much.

I don’t think the Empire would be inclined to prevent all non-military holonet use, but they would certainly monitor all known holonet access, and effective repressive regimes can make it very difficult for rebel organizations to communicate quickly and easily.

A communication system that widespread would likely have a federate structure, much like the internet - many networks connected together using well understood protocols for the transfer of information from one to another, or to individual nodes inside. At best, then, the internet could perhaps have a sort of 'Great Firewall of China' that would monitor traffic and prevent access of restricted materials. However this is effective in China because what they (mostly) want to prevent is access to resources outside of China itself. So, the Empire, for example, would find it easy(ish) to filter traffic into and out of Hutt Space extensions of the Holonet. Its much more difficult to monitor information inside of a country - think of if the NSA tried to monitor every email sent from anyone to anyone inside the united states. It would be damned hard, and just about impossible to do without the creation of some REALLY powerful artificial intelligence, not to mention MAJOR upgrades to the infrastructure of the network, since you'd suddenly be doubling the network traffic at least (every byte now has to be sent to an imperial processing node, and then out again to its destination). This is expensive, and time consuming considering that the Old Republic with its very loose confederacy of systems would've provoked outrage had it tried to institute something like this, and the Empire just hasn't been around that long - this is a WAY bigger project than the Death Star.

More likely, what the system would do, I think, is simply look for patterns along routes it knows (through human or other intelligence) to be suspicious. The emperor, for instance, would have close scanning occurring on the Alderaanian Royal Family's communiques, and a lower pattern level scanning on Adleraanian communication in general, simply because it knows its a dangerous place.

But then, the other thing to remember, I think, is that the canon materials (at least to my mind) simply give the impression that communication across the universe just ain't as instantaneous or comprehensive as it is on earth. This explains a lot of things: how easily the Empire could hoodwink systems throughout the galaxy about the 'betrayal' of the Jedi, how important it is to have info chants and news delivered by individuals. I like to think of it as a low-level relay - it can communicate some static traffic (the daily tv programs, sent once and distribute to requesters locally) and a small amount of dynamic traffic - important messages, expensive to send, usually highly minimized. More like telegraph than like internet. Pay by the word. So, those holonet transmissions are disgustingly expensive, the sort of thing you use if you're Darth Vader, or you're trying to impress a very important client. By that logic the really important things to filter - say, an impartial press - are much easier to suppress.

Restricting FTL comms to only military use would mean economic suicide.

Do you mean just the holonet or are you including FTL courier ships? If you mean both, then I agree.

But if you mean only the holonet is banned from public/economic use, there are still FTL comms in Star Wars. When/if the Empire took over the holonet and banned general, public use, a new industry would have arisen of transports carrying messages at FLT speed. Not instantaneous, but still well beyond FTL. Every transport, passenger liner, and freighter out there could be carrying public messages stored in the ship's computer or in small data crates stacked up in the cargo hold with destination worlds marked upon them.

Carrying a load of hyperdrive modules from Corellia to Alderaan? Be sure to drop by the local Interstellar Communications office and fill up the remaining corner of your cargo hold with data crates headed to Alderaan for some extra credits. There could be courier companies that do nothing but run constant routes back and forth with fast ships with nothing in the cargo bays but data storage.

ETA: The Traveller game universe used this method of communication. The Traveller Empire had a network of speedy communication ships constantly delivering messages of state.

Exactly what keeps airlines flying as cheaply as they do. Passenger aircraft typically carry the mail.

I mean comms. One of the biggest sanctions that can be applied by the US is to sever a nation's access to the SWIFT system, which is the currency transfer system for large monetary sums. You flip the switch on instantaneous comms in the galaxy and the economy collapses, there would be no way to make that happen with ships.

In October 2016, SWIFT recorded an average of 26.04 million FIN messages per day. The traffic grew by 7.8% versus October 2015. This brings the year-to-date growth to 6.0%. Reporting messages contributed to two-thirds of this growth.

That's just for our wee little planet, scale that up to a galaxy.

In 1996, AOL was doing millions of e-mail messages per day. That continued to scale as the number of users grew, to the peak of two dozen million e-mail messages per day. I know this because I was the Senior Internet Mail Administrator for AOL from 1995-1997, and I helped architect, build, and monitor that system.

These days, gmail and Facebook do billions of electronic messages per day.

The thing that is scary about SWIFT is the third-world banks that are connecting to the system using old insecure methods, thus allowing them to be hijacked and hundreds of millions of dollars immediately at risk, and over 11,000 other financial institutions that are also exposed.

So all those floppies and CD's were your doing? You bastard... not really... but you are the closest target

And the NSA has tapped into those email trunks and is sucking in all that data... trouble is sucking in everything is inefficient because finding the needle in the haystack is difficult...

We used them as drink coasters. We had a lot of free drink coasters in the company. There were guys there who prided themselves on how extensive their collection was of the various drink coasters that had been issued by the marketing department.

And the NSA has tapped into those email trunks and is sucking in all that data... trouble is sucking in everything is inefficient because finding the needle in the haystack is difficult...

Ironically, when I was working there, the lead developer of the AOL mail system had made a point of not keeping any backups of user mailboxes that were more than 24 hours old, and aggressively aging old messages out of user mailboxes once they had read them. This was intentionally designed to minimize our attack surface if Law Enforcement Officers decided to show up and start waving around court orders.

So far as I know, at least during the time I was there, no LEOs ever showed up, and no court orders for that kind of information ever came down.

With regards to spying, AOL has long since stopped being the real risk. AT&T, Verizon, and all the other major carriers are a much bigger issue.

This was going on long before Snowden helped bring it to light, but see https://www.nytimes.com/2015/08/16/us/politics/att-helped-nsa-spy-on-an-array-of-internet-traffic.html

pretty much how I feel also. But Disney canon seems to do whatever they want now because of lazy writing. So as far as the movies are concerned now, Galaxy spanning instant communication is possible, and everyone can have a Holocommunicator on their wrist.

So as far as the movies are concerned now, Galaxy spanning instant communication is possible,

"Now?"

Vader communicated instantly with the Emperor from the Anoat system to (presumably) Coruscant as far back as 1980.

Well Vader is a unique situation, he's party to the best the Empire has to offer...okay in technology maybe not officer staff *cough* Ozzel *Cough* Needa *Cough, cough*

And Palpatine issued Order 66 to all the Clone Troopers coms from Coruscant. And that was under George. This type of communication exists and the Rebels need to it to do what they did. They likely had to hack the system to do it. Kind of like how pirate radio stations used to do it

*sigh* You have not been reading the last few posts of mine. But this is the internet, someone will always show up to point a finger and say "YOUR WRONG" at the slightest statement taken out of context. I should say "It is possible for EVERYONE, including rebellion, and even can be done in hyperspace, literally no restriction now except maybe a dense asteroid field giving you a weaker signal"

do whatever they want now because of lazy writing.

Old George been doin that since the 70's!
