Actually if you assume that tradelanes aren't superluminal, freelancer universe makes a bit of sense.
Quote:[01:59:58] Maverick O'Howell: So if you, as they say in game, "Initiate tradelane sequence", you start up the field of energy. Positive or negative as it is. Whichever it is, I don't know. Assumed positive. When a ship gets up to the lane, The ship starts up a field of its own which repells from the lane, shooting the craft worward within the network. Upon traveling, it reaches the next lane where it repells more. You travel so fast, that it's a brief repell, just to maintain speed. Upon exiting the lanes, the endlane has an early switch, repelling the craft. The fields working against each other, slows the craft down to an exit speed and turns off.
[02:00:44] Protégé: There's one hole in this theory.
[02:01:09] Maverick O'Howell: The constant accelleration after you leave that first lane. Thought about that.
[02:01:28] Protégé: Yes.
[02:05:06] Maverick O'Howell: The only way to make it plausible in this hypothesis would be that the field gets stronger. While the craft remains the same. You still have accelleration as long as the field is projecting outward from the lane, it would still propell the ship forward.
"On the other hand, what some physicists refer to as "apparent" or "effective" FTL depends on the hypothesis that unusually distorted regions of spacetime might permit matter to reach distant locations in less time than light could in normal or undistorted spacetime. Although according to current theories matter is still required to travel subluminally with respect to the locally distorted spacetime region, apparent FTL is not excluded by general relativity."
