:::::::::WHY would it invalidate every counterexample here? There's a lot more to relativity than e=mc<sup>2</sup>. --[[User:ClearView2011|ClearView2011]] 14:13, 3 December 2011 (EST)

::::::@GMilhouse: Newton's second law is not <math>F=ma</math>. It is <math> F=\dot p</math> (Newton's formulation in ''Principia Mathematica''!), where <math>p=mv</math> (non-relativistically) is momentum. This includes the possibility of varying mass - necessary for instance when modelling rocket flight. Plus, can you provide a reference to an experiment where a non-zero mass particle was accelerated to the speed of light? --[[User:FrederickT3|FrederickT3]] 14:06, 3 December 2011 (EST)

:Maybe I should cut to the chase. Yes or no. Does the fact that nuclear reactors exist invalidate every possible counter example on this page, and every valid example merely represents a physics that the current theory does not yet accommodate? If so, then surely this entire page should be deleted. --[[User:GMilhouse|GMilhouse]] 14:16, 3 December 2011 (EST)
