Some people are having issues with Mass Effect 3 and it's allegations of space magic. Do I need to remind everyone that all Sci-fi is space magic on some level? So instead of questioning the plausibility of how the hell Mass Effect fields work and how even Faster than Light Drive is possible by reducing the weight of an object to zero, you guys are stuck up criticizing the game's scientific implausibility as a criticism to either the premise of the whole game or its ending
I'll give you one example, the quantum entanglement device used for communication in Mass Effect 2, 3, which is when one particle on one side affects another particle on the other (therefore being entangled) allows real time communication across the galaxy. I'm sorry to say, but that's not how Quantum entanglement works, it does not allow communication to be faster than light.
All Sci-fi is space magic, just because it's explained to you in a science way, doesn't mean it's actually plausible or that's how it works.
