As I said above Mass Relays are explained as some sort of teleportation tech, but this 200X or 4382x light speed is space magic, with dragons and unicorns. Sure you might get there, but you might get there at the prime of the Prothean Empire timeline. Or 43820000 years into the future if you went 1000 Lys
Canonically FTL works by using mass effect fields to lower the mass of the ships. Yeah, it's space magic, but any form of FTL (including things like wormholes or the mass relays) is because as far as we know in real life FTL is simply completely impossible.
FTL is basically like warp drive. It's just some form of getting around the universe at high speed while ignoring relativity. And at 12 light-years per day it's already much faster than the official figures for Star Trek's warp drive (although ships in Star Trek more often moved at the speed of plot).
And you can't use relativity to calculate time dilation above light-speed, because relativity explicitly isn't valid at or above light-speed.
Oh I get that but even in stat trek they explained (or tryed) the physics of warp travel. Here its space magic, since the speed of light is basically the speed of light photons, if in theory you wanted to go 200x or whatever faster then that by reducing that mass of the object, the reduction would be of 200x that of a proton.
A photon has 0(zero) mass
Overall even a mass effect FTL cannot work by reducing the mass of an object or even making it negative. Since you still have your standard issues of time dilation which becomes negative as you get into FTL ranges. (meaning a ship would be able to return to it's starting point before it actually left)
That breaks causality and as such cannot be the FTL in mass effect or anywhere else really. Doesn't help that your mass becomes infinite the moment you hit LS.
Due to time dillation not being an issue in ME, we can actually infer, that the ships don't actually travel in normal ways.
What instead probably happens, is that the mass effect FTL drives create an alcubiere drive or something similar.
- Essentially a buble of real space that moves faster that the speed of light. But what moves inside of this buble still has it's own frame of reference. It basically works by contracting and expanding space time before and after the ship.
What a mass relay seems to do, is propel this bubble forward even faster.

"No, because of 2 things
i) You're attempting to use RL physics in a science FICTION game. As i already said, any dicussion must use the framework established by the author which in this case is large represented by the CODEX
ii) Negative mass as a property of exotic matter and resulting anti gravity properties have already been talked about before in the formation of wormholes http://en.wikipedia....i/Negative_mass"
----------------------
In theoretical physics, negative mass is a hypothetical concept of matter whose mass is of opposite sign to the mass of normal matter.
That means, maybe, could be, I think so, I have faith and all that.
The problem Im haveing with FTL is that the author of this game doesnt explain how this is posible.
He doesnt have to explain it using RL physics, it can be donald duck physics, but it still has to make logial sense. I have read alot of SF, and the thing was even if the author made up a new form of mathermatics the FTL was still explained logically within the frame of the story physics.
The problem in this game is that they are using RL physics to explain something that is disproved by those physics.
Obviously we have to make a suspension of disbelief. Because when you think about it, Earth could currently defeat any reaper ground force that would make a landing. The repears and husks are pretty much instant dead and outmaneuvered on earth.
As our current weapons are somewhat stronger and tougher than anything in the MEuniverse. Obviously they could pummel us from orbit and we'd have no real way of retaliation. But on the ground they don't stand a chance. (or Earth's atmosphere. Harvesters and their aircraft would be fodder even for old migs).
For reference - a capital reaper's main cannon is weaker than current nuclear weapons. A dreadnaught shell is only strong as two nagasaki sized nuclear weapons.
But even so, we can still have some fun theorycrafting what a situation would be and on what principle and speeds some of the thing in the ME universe work. FTL is one such example.
The fact that the universe is not hard sci fi shouldn't stop us from doing this. Obviously most universes tend to have some internal logic. It's certainly possible to work with that internal logic.
