Comment on “Bell’s Theorem Versus Local Realism in a Quaternionic Model of Physical Space”

In this paper, critical errors found in the paper “Bell’s theorem versus local realism in a quaternionic model of physical space,” by J. Christian, published in IEEE Access, are pointed out. The above paper, in fact, contains several conflicting models. None of them form counterexamples to Bell’s theorem. Most of Christian’s paper is devoted to a model based on the detection loophole due to Pearle (1970).
