The Rydberg constant and time dilation
The argument below gives R(v)/R(0) = (2 − β²)β³, which equals Einstein's time-dilation factor β multiplied by (1 − v⁴/c⁴). The two agree to order (v/c)², so the experiments of 1995 could not tell them apart, as Aspden said. Fast-ion experiments now can: lithium ions at 34% of the speed of light match time dilation to ±2.3 parts in 10⁹ (Botermann et al. 2014), where this formula predicts a 2.6% shift. The earlier version in Physics Unified (1980) predicts 0.8%. Both are excluded. An aether theory need not fail this test: Lorentz's aether electrodynamics gives time dilation exactly.
Energy deployed in electrodynamic interactions is physically separate from the electric field and cannot be recovered fast enough to affect photon emission. An atom moving at speed u then has a spectral redshift proportional to 2β2-β3, where β is (1-u2/c2)1/2, identical to relativistic time dilation, apart from minor differences of order (u/c)4, but the latter put the relativistic interpretation in doubt.
"Manuscript Ho738:
Atomic Spectra and the Moving Atom, by H. Aspden
The paper is very nicely written but I do not think it is physics, more science fiction. The author is clearly very open minded about the foundations of his subject, being willing, apparently, to jettison relativity, quantum mechanics, even conventional classical electrodynamics. However, since these theories are accepted by almost everyone else, he must provide very strong arguments, which should be explicitly mathematical and include convincing detailed sample calculations, before a physics journal such as Physics Letters A should publish the ideas. I insist on the need for mathematical formulation of the ideas because it is all too easy to be carried away in a verbal phantasy which has only the lexicon of physics but none of its tight logical structure."
"Please find enclosed the response from the referee(s) on your paper. We regret that on the basis of the referee's report your paper is not suitable for publication in Physics Letters A. We must therefore unfortunately decline it. Thank you for submitting your work to our journal."
