You guys are WAY off base. Stop thinking that the Normandy 2 is sending signals through space while travelling FTL. That's not what's happening. EDI makes it clear that they use quantum entanglement, and although quantum entanglement is real science, they expand on it with some fiction, and EDI explains the sci-fi spin on it quite nicely.

Let me explain in simple terms. A single particle of light, known as a photon, is split in two, but an unusual relationship between that two 'halves' exists that can't be explained by classical science. Einstein referred to this strangeness as "spooky action at a distance". What happens is that the two halves of the photons, basically appear to share the same existence, even though they are moved very far away from each other. Basically, one half responds to changes in the other half.

So in ME2 the idea of a quantum entanglement communications system is that you have one half of the entangled pair on the Normandy, and the other half is far away, maybe back on Earth. The communications system on the Normandy changes the state of its half of the entangled pair, and back on Earth, the communications system there instantly registers the changes in the other member of the entangled pair. Information is sent not across space, but via a protocol (perhaps binary or something similar), just between the Normandy and its own entangled particle. Then back on Earth, the communications system there registers the changes in its entangled particle, and thus can instantly translate the changes perceived into information via the same protocol.

So in ME2, information is not sent in a signal that travels through space, rather through a real life phenomena that transcends space. No tunnels, no need to move energy in waves or rays through space, no magical 'mass effect'.

The simplest way to understand FTL communication applies to all technology in Mass Effect:

Dark matter is magical.

???? If you talk to EDI in the game, she doesn't say that FTL communications use dark matter or the mass effect. She says it uses quantum entanglement, which may appear to be magical, but isn't.

You're thinking of the qunatum entanglement system linking the normandy to tIM.  Ordinarily, ftl communication is performed by piping lasers through ftl space between comm buoys.

You're thinking of the 'FTL com grid (network)', which has nothing to do with the Normandy specifically. It's a static grid the Normandy can interface with. The com grid couldn't use LASERs (Light Amplification by Stimulated Emission of Radiation), as they only emit light. Light only travels at the speed of light. You'd need to use tachyons (Greek for 'Faster than Light') for FTL communications that way. But tachyons aren't mentioned that I'm aware of.

The Normandy itself can only use FTL off the grid via quantum entanglement.

Btw... your link is a wiki, notoriously poor references.

I think he means this which is straight from the in-game Codex

Communications



Real-time communication is possible thanks to networks of expensive mass relay comm buoys that can daisy-chain a transmission via lasers.



Comm buoys are maintained in patterns built outward from each mass relay. The buoys are little more than a cluster of primitive, miniature mass relays. Each individual buoy is connected to a partner on another buoy in the network, forming a corridor of low-mass space. Tightbeam communications lasers are piped through these "tubes" of FTL space, allowing virtually instantaneous communication to anywhere on the network. The networks connect across regions by communications lasers through the mass relays.



With this system, the only delay is the light lag between the source or destination and the closest buoy. So long as all parties remain within half a light-second (150,000 km) of buoys, seamless real time communications are possible. Since buoys are maintained in all traveled areas, most enjoy unlimited instant communications. Ships only suffer communications lag when operating off established deep space routes, around uninhabited outer system gas giants, and other unsettled areas.



During wartime, comm buoy networks are the first target of an attack. Once the network is severed, it can take anywhere from weeks to years to get a message out of a contested system. In systems where a buoy network has not yet been built or has been destroyed, rapid communication means ferrying information through high-speed courier ships and unmanned data drones.

[dakkman]

Oh, I see what the wiki is suggesting, that every bouy is a mass effect relay. In that case, there would just be a bottleneck between the ship and the first bouy.

But is this supported in the game? I don't recall such an explanation in the game. (EDIT: Thanks A.N.A.N.)
 
In any case, the Normandy herself cannot send FTL signals, other than via quantum entanglement. This is made clear in the game (the link I posted).

Btw... does anyone realize how little 150k KMs is in space? Less than half way to our moon. You'd have to fly pretty close to the bouys to be on the grid. To cover the volume of our solar system with bouys, you'd need many billions of them.

This also makes me wonder... why not just have a buoy (mass relay) on the ship, to remove the need to contact the bouys via laser communication?

Because people at Council tech level don't have the tech to build mass relays?

I confess, the whole mass effect concept baffles me. I know dark matter pushes the galaxy to expand "faster than the speed of light" although that's really an inaccurate way of looking at it and it also wouldn't apply to physics within the galaxy.

Reducing a mass to zero magically might conceivably result in light speed travel without violating Einstein's speed limit but FTL? Maybe dark energy is supposed to create a negative mass or something.

Well, you can travel at infinity speed if your mass is negative, which is how the mass relays work I think.  I don't think it actually violates Einstein in a major way.  Einstein says that nothing can cross the light barrier; however, it doesn't mean that the light barrier is actually a speed limit.  If you are travelling faster than the speed of light, you can't go slower than the speed of light (eg tachyons).  Mass effect fields circumvent this in a plausible manner.

[Yxiomel]

EDI's quantum entanglement tech (which is based on real physics, buut with a nice dollop of sci-fi) only related to your comm link to TIM. The rest of your comms are through FTL bouys.

You can travel beyond light speed (but not below) if you are a tachyon, which is not negative mass, but imaginary mass (ie sqrt(-1)*mass). The idea is to get around imaginary masses by redefining mass so that while looking at tachyons, all tachyon amsses are real, but sub-light masses become the imaginary ones. Mass effect fields are meant to reduce mass, not give it a complex phase. Accoring to the codex entries, they do increase light speed though - so you don't have to break your presonal mass effect field specific light speed to travel faster than the conventional speed of light. Kinda makes sense. Kinda.
