Nonlinear Continuum Mechanics, Electrodynamics and Ether Theories

All attempts of describing fundamental physics with continuum mechanics in the 19th century have been falsified by the famous experiments by Michelson and Morley that seem to have disproved the concept of an aether. The aether theorists however never thought of particles as being topological defects creating a displacement field - which is not astonishing, since the first examples of such defects, dislocations in solids, were discovered in 1934 by Taylor, almost 30 years after aether theories had disappeared from the stage of theoretical physics. In view of the results of Frank (1949) and others, however, one must say that the wrong concept was not describing spacetime as an elastic continuum but a wrong or missing picture of particles moving in it The hypothesis that elementary particles could be topological defects in an elastic continuum is backed by interesting results of modern nonlinear continuum mechanics (Truesdell 1960, Beatty 1987, Hayes 2000). This is discussed in the papers
