To me the equation E=MC^2 appears to be fiction as well. It doesn't work in experimental analysis. I've never seen anyone verify or prove it. Just looks like propaganda to me.
How about pair production:

"the loss of mass to an atom and a neutron, as a result of the capture of the neutron and the production of a gamma ray, has been used to test mass–energy equivalence to high precision, as the energy of the gamma ray may be compared with the mass defect after capture. In 2005, these were found to agree to 0.0004%, the most precise test of the equivalence of mass and energy to date."
