Attempts to prove E=mc² (view source)
Revision as of 04:21, October 1, 2016
, 04:21, October 1, 2016→Experimental claims: Rebuttals should be indented.
Scientists commonly claim that E=mc² is true for what are, in fact, ordinary chemical reactions that emit energy, even though the mass change implied by such reactions is far too small to measure. This is because the formula can be proven (see below) for ''all'' interactions. So no one claims that chemical reactions ''prove'' or ''verify'' E=mc², just that it logically must be true. Nuclear reactions are another matter. The formula is verified constantly, and, in fact, its consequences can be seen in the atomic weights in periodic table charts hanging in science classrooms all around the world. Nuclear-fusion reactions, such as the transformation of hydrogen to helium, also demonstrate the validity of the formula E=mc². The transformation of 4 atoms of <sup>1</sup>H into one atom of <sup>4</sup>He occurs constantly in the Sun, and has a mass defect of .02916 amu, which works out to 27.162 MeV. Several interactions are involved in the total transformation, and their energies have been observed in the laboratory. Alpha decay energies have been measured for many isotopes, and agree with the mass change. See [[Quantitative Analysis of Alpha Decay]].

Broken clocks are correct twice a day. E=mc² is correct all the time.
