Aschlafly, do you know what E=mc^2 means? You say that "E=mc² is a meaningless, almost nonsensical, statement that purports to relate all matter to light." No. What it says is that matter is just another form of energy. That's it! It says nothing about unification of electromagnetism and gravity. Moreover, the m in the equation is inertial mass, not gravitational mass! If you look at any decent book on SR, it is the inertial mass that appears in the equations of relativistic energy-momentum.

Many questions in the sections above are still unanswered and I'm especially waiting for Aschlafly to answer those in the section ''[[Talk:E%3Dmc%C2%B2#A_few_questions_for_Aschlafly_regarding_the_experiment_of_Cockcroft.C2.B9_and_Walton|A few questions for Aschlafly regarding the experiment of Cockcroft¹ and Walton]]''.
Aschlafly, could you at least provide me with your interpretation of the bolded sentence of Cockcroft's lecture: ''It was obvious then that lithium was being disintegrated into two α-particles with a total energy release of 17.2 million volts. '''This energy could be provided by a diminution of mass of 0.0184 mass units'''''? Feel free to show your calculations!
