Critics maintain that such verification is impossible due to the utter lack of any logical justification for that science fiction formula.

Cockcroft and Walton "''did not see their experiments as a ''test'' of Einstein's mass-energy relationship; rather, they simply used that relationship in their analysis, assuming it to be valid ''"<ref>Roger H. Stuewer: ''Mass-Energy'' in ''Einstein in Context'', Cambridge University Press</ref> The first to stress this aspect of the experiment was the eminent physicist Kenneth Bainbridge in 1933:
{|class="wikitable" style="background:lightgrey"
|The gain in energy in the reaction is 16.97×10<sup><small>6</small></sup> e-volts, an energy equivalent to 0.0182 mass units on the O<sup><small>16</small></sup> scale if ΔE =C²Δm. Taking Aston's values for the mass of helium and hydrogen and the author's value, 7.0146±0.0006 for Li<sup><small>7</small></sup>, the mass change is 0.0181 ± 0.0006 in the reaction which may be represented as Li<sup><small>7</small></sup> + p → 2α . Within the probable error of the measurements the equivalence of mass and energy is satisfied.'' --Kenneth Bainbridge
