The following is a paper by H. Aspden published in The Toth-Maatian Review, v. 5, pp. 2827-2833 (1987).
Abstract: One of the most basic questions in physics is whether there is a degenerate form of the electron, a charge of smaller mass than that of electron. If there is then it is likely to be a primary constituent of the background field medium we recognize as sustaining electric displacement, namely the aether. This paper discusses the evidence indicative of the existence of such a particle, a sub-electron, having an effective mass of 1/24.52 that of the electron.
Commentary: In this general article the author introduces his aether theory and shows how the recognition of a sub-electron, in the form of the virtual particle which occupies the aether lattice sites in the vacuum medium to endow it with quasi-liquid crystal properties, plays a direct role in relation to three physical phenomena. These are in the determination of the temperature of the Sun, the solution of an unexplained mysterious fact of astrophysics, which has been named the Wesson constant, and the mystery of the mass of the neutral pion. This is besides the explanation 2.7 K cosmic radiation background temperature, as presented on p. 177 of the author's 1980 book 'Physics Unified'.
