In the popular video game Mass Effect on Xbox, you can find explanations about the technology that is used in the game. It seems that some of the technology is based on things that could be realized in real life and some that seem questionable.
For example in Mass Effect 2, you can have a cloaking suit, which I see can be realized with a combination of different meta materials in real life. Mass effect particles are something that are clearly made up, but could these be gravitons interacting with other particles or something?
My question is, how much of it is based on real physics that could one day come true, and how much of it is based on just made up stuff with techno-lingo?
