Member since:December 04, 2008Total points:89 (Level 1)While playing a game Mass Effect 2, it explained how the entire galactic civilization built their technology around older technology and a resource called element zero. while learning of this i asked myself " aren't we technically doing the same mistake, with fossil fuels being our resource, and our technology relying on it"? so i went searching the web for anyone who has written a similar theory, but my searches came back empty. has anyone even published anything on such a theory?Answer Question
