:::*''It's in the realm of science fiction at best, and not as good as other types of science fiction.'' No, it's not - that's just wishful thinking of you part. Even undergraduates can perform experiments which show relativistic effects - see [http://arxiv.org/abs/1108.5977v1 Relativistic Electron Experiment for the Undergraduate Laboratory]

Actually, it gets demonstrated in practice about 3x10<sup>10</sup> times for every watt-second of power generated by a nuclear power plant. Aside from observation, the theoretical question of ''why'' it should be true (and why the proportionality constant must be c<sup>2</sup>) was logically deduced, by Poincare, Einstein, and perhaps others (Roger Schlafly would be an expert on this point), before it was ever observed. The last paragraph of Einstein's 1905 paper, after deducing it theoretically, speculated that it might actually be observed in Radium decay. It was, and the rest is history.
Clear expositions of why it must be true on theoretical grounds are not always easy to come by. I like to think that the page I wrote on another wiki gives a clear and concise proof. Anyone interested in my making it available here? [[User:SamHB|SamHB]] 23:06, 8 January 2013 (EST)
