Einstein has been proven wrong about FTL, because there are sub-atomic particles capable of traveling faster than the speed of light. Besides, who are we to say the Laws of Physics have been discovered, and Science will never find new "facts"? Just because we can't travel faster than light now doesn't mean it is impossible. Every time I hear someone quote Einstein I get mad... Back in the Medieval Ages, there were many scientific phenomena that were "unexplainable" and were treated as mystical and/or witchcraft. That didn't make it any more fake or "fantastical", did it? Now we know the scientific truth to a great many of these so-called magical occurrences. Who knows, 100 years from now we could have civilization on Mars, something that many people would swear to you was impossible only 100 years past. BTW, even though this GAME has many realistic features, it is still a GAME and there are plenty of un-realistic things about it, such as Kerbals, the coloring of the planets, etc. So, it is perfectly reasonable to find FTL drives in this GAME. It isn't a simulator, after all... Maybe a suggestion to a mod to close this thread? After typing this response, I realized that there are many threads regarding this subject already on the forums. No need to keep beating a dead horse. The horse has been beat; lets just wait until KSP has been around a while longer and see what the future has in store.
