Yeah, warp drive is a popular theory and was when Star Trek was created. To understand FTL in Mass Effect, some things must be understood about physics. As velocity increases, an object's inertia increases. That means the faster something is moving, the more energy it takes to make it go even faster, approaching infinite energy the closer it gets to the speed of light. The amount of this inertia is called relativistic mass. Mass effect fields reduce the relativistic mass of everything in the field, including light, effectively raising the "speed limit" in that pocket of the universe. Right, but back into the relativity equation, reducing mass is only one part of it. Even if we managed to "teleport" a human to another galaxy, time on Earth would pass faster than it does for the person that's been transported. The farther away they are, the more time "dilates". Which is back to the original point I had made. Because of relativity, the first scene of ME:1, when they hit the first relay to get to the citadel, by the time they got to where they were going, the time would actually be BEFORE they hit the relay. Further, objects in space with a positive mass attract objects to them (gravity). Since, as you said, the Mass Effect field reduces an object's mass to zero, we now have an object traveling much faster than the speed of light, entering a system with a 0 mass. The resulting "push" (massless objects or objects with negative mass repel in space) would likely be catastrophic for any planets nearby. I don't think distance has anything to do with it, only velocity. Though there would be two images of the ship: first, it would appear to pop into existence as soon as it dropped out of FTL. Then you would see it traveling toward you in the distance until vanishes at the point it dropped out of FTL. Mass effect fields don't reduce mass to zero, they just reduce it by some unstated amount. Something with zero mass would reach infinite speed at the slightest thrust. The wiki says specifically that this type of FTL doesn't experience time dilation, so I assume that is stated in the codex of one or more of the games. The wiki doesn't say why, but I have a theory. Time dilation occurs because the speed of light must remain constant to the outside observer for the universe to make any sense. Mass effect fields accelerate the speed of light. Now, because light from the ship would not retain its speed once it leaves the mass effect field, watching the ship in transit would not tell you where it is or even where it was in the same way you can observe any other object. But in that pocket of the universe enveloping the ship, relativity works differently because its speed is relative to a new speed of light. |

Distance has everything to do with it. That's a part of relativity and what I've been trying to get through to you.
The International Space station, for example, experiences time that is .00000014% slower than that on Earth. It's not traveling at any significant speed. It's location is the reason it experiences dilation. The FARTHER you get from any given point, the MORE you have it. There are a lot of people that believe that relativistic physics only apply to the speed of light, but it's general relativity that we're talking about when it comes to this distance. IE: Your RELATIVE location to Earth.
This is a part of relativity that isn't based on local phenomenon.
Many TV shows/Movies ignore it because so many people are confused by it, but it's a very basic law of physics. If you leave Earth's orbit, you're literally aging slower than everyone on Earth.

If you leave Earth's orbit, you're literally aging slower than everyone on Eart Everything in the universe is some distance from everything else in the universe. So if distance dilates time, everywhere is both faster and slower than everywhere else. Time is slower on the ISS because it is moving faster. Gravity slows time, not speeds it up. Velocity is just making up for it on the ISS. I love learning about this stuff, so if you just haven't been explaining it well, please try again or link to something that you think does a good job. |

Velocity is just making up for it on the ISS. I love learning about this stuff, so if you just haven't been explaining it well, please try again or link to something that you think does a good job. I had to correct my own understanding. Distance matters in relation to gravity sources. Point is briefly illustrated here: VideoYour statement, that everywhere is faster/slower than everywhere else is true...depending on gravity... (the video is Neil deGrasse Tyson) This is better example of what I'm referring to (NDT says 2 factors affect time speed and gravity) it seems that the the more gravity you have, the slower time passes. It's not the same point I was trying to make before, but it still furthers the idea that the Mass Relays would not be able to "nullify" relativity. They would have to modify the gravity on each individual world to make time pass at the same rate and, if you read the codex of each planet in ME, you can see that they have different "G" forces on each planet. Video 2
Edit: I like the concept of expanding my understand of things. This conversation as revealed a misconception of mine about relativity, but I WAS correct about the relays being unable to "correct" the second factor in relativity (gravity). Sure, they can maybe account for and correct time dilation in relation to velocity, but not for gravity. |

Only in a Mass Effect thread could you go from QTE communication to Neil deGrasse Tyson in less than 2 pages XD

Didn't Alec said in none of his final logs that none of the QEC set for communicating with Milky Way work? Implying that end points of QEC in Milky Way were destroyed by Reaper War. He did receive early reports when they were already on travel about both the Alliance and the Hierarchy getting attacked by the Reapers so the QEC were working at least for a short time. The Reapers destroying everything is likely considering they took all home planets (except Surkesh i think), but i still wonder if the Benefactor didn't have people inside the Nexus and each Ark sabotaging those comunicators to not leave anything to chance. All except one Ark. The Lost Ark. But then who and when would they have done it? I could see some agents doing it, but would it be while en route? Or possibly directly after reaching Andromeda. Or maybe it wasn't even agents. It could have been...programmed that upon arrival the system was to be severed. |

Ofc, the Scourge may have had a negative impact on the longer range capabilities of any QEC without us even knowing.
The Kett were having the same problem trying to communicate back with their Empire home base. That was some kind of sabotage, though. But they were sending messages back to the empire, but the empire was not getting them, and complaining about it.
