Obviously, that's a bit in the air right now as to whether or not its the entire fleet ...
Fair enough, but the video with producer Jesse Huston answering questions from fans, he clearly says the Alliance Navy has been practically wiped out. I'll edit this post later when I've found the link.
EDIT: Here it is
http://live-event.ea...at/mass-effect] Video Walkthrough and Q&A with Mass Effect 3[/url] Starting June 8th at 2PM PT / 5PM ET. The quote is from ME3 producer Jesse Huston.
21:30 – “At that point, the Reapers have basically wiped out the entire Alliance Navy.”
This pretty much explains what happened to Batarians as well. Reapers are killing machines honed to perfection.
What comes to communication, why weren't Batarians plead for help from the Council, remember those dark switches from mass relays? They can be used to control mass relay locally.
Now, practically all FTL communication (excluding Cerberus stuff on Normandy SR2) goes trough mass relays. When Reapers take control of mass relay in area they are going to attack, they can also cut out all the FTL communications, be that warning, or request for help.
What comes to Alliance spying satellites or such, they may be there but they also use mass relays to transmit information back home. Also, Alliance stealth tehcnology weren't effective against Collector cruiser, which I think used Reaper technology.
Then speed... at least some Reapers are huge. They can indoctrinate masses and get them inside, jump to earth and "passengers" in this case Batariens are made Cannibals, Batarian husks on flight. We saw something like this in already in ME2.
There are weak points in my theory though. If Reapers took control of when Charon relay when they arrived in Sol system, how would Shepard ever escape?
My speculative fan ****** is that Batarians tried to fight Reapers by themself or for some other reason didn't tried to inform the Citadel Council what is happening.
However, perhaps Alliance navy, in their hopeless battle against the invading Reaper fleet bought just enough time for Alliance, to inform Citadel Concil about the events, and as Citadel can control all mass relays in the mass relay network, they can keep Charon relay open from there for Shepard, remains of Alliance fleet and perhaps civilian refugee ships to escape trough it.
Side note:
Anyone recall Prothean recording on Ilos from ME1?
