I'm not saying it's magic because it's incomprehensible, I'm saying it's magic because they pulled it out of their backsides as a convenient and science-sounding way of making their space opera work. Most sci-fi works on at least a tiny bit of space magic; some try to stick as close as possible to currently acceptable theories and really explore the ramifications of the technology. Most, like Star Trek, gloss over the details and focus on the stories it makes possible. Mass Effect exists on the softer side of the scale, using comic-book style logic because it translates well into video games, hence we have a substance that allows FTL travel in both warp-drive and worm-hole style, creates artificial gravity, enhances (enchants?) weaponry, and gives people magical powers.
