The following is a paper by H. Aspden published in Lettere al Nuovo Cimento, v. 38, 206-210 (1983).
Abstract: Predictions from the author's recent alternative explanation of the apparent time dilation evidenced by meson lifetimes suggest that the dilation of lifetime observed should be lower than that indicated by special relativity if the tests are made a low enough energies. Reported experimental data supporting this proposition are discussed.
Commentary: When scientists seek funding for new and better experiments needing more powerful equipment they concentrate their field of research into territory at one end of the experimental spectrum. Einstein's theory is supposed to hold valid over the whole spectrum. The subject paper shows that this author's alternative explanation of the apparent 'time dilation' of fast-moving muons and kaons points to differences from the Einstein predictions that can be tested experimentally over the mid-velocity ranges. The reported experimental data supports the author's theory and not that of Einstein.
