The following is a paper by H. Aspden published in Physics Education, v. 21, pp. 261-262 (1986).
Commentary: Here, in this periodical which is published by the U.K. Institute of Physics for physics teachers, the author draws attention to the alternative non-relativistic ways of explaining the perihelion anomaly of planet Mercury. Quite deliberately, the author did not refer to his earlier paper [1980b] in the main periodical series published by the U.K. Institute of Physics, which showed first-principle justification for alternative non-Einstein theory. The reason was that referees in their 'peer review' activity do not approve of author's urging acceptance of physics which they see as controversial, particularly if attention is drawn to earlier work in a way which leaves them no room for doubt or dissent. The science community is now wedded to Einstein's theory and the bond is so strong that the author believes it will take a powerful breakthrough on the vacuum energy front before physicists will turn away from their mathematical abstraction and focus on reality!
