What is / are the primary criticism(s) against Einstein-Cartan-Evans (ECE) field theory?
I'm searching for an undergraduate-level* explanation of the criticisms / details.
(The first link is openly accessible [i.e. arXiv], but the others are from MathSciNet; (as I don't have access to MathSciNet, I'm wondering if someone with access may provide their take on the contents.))
(*To be specific, I have background in the following courses: Physics: First-year Mechanics, Basic E&M (but not electrodynamics); Math: Calculus I, Linear Algebra, some Differential Equations.)
