Hi FQXi !
The model in the attached article is not "alternative". Just a slightly different look at the same reality.
In a nutshell, the model can be described as combining a relational view of physics with the concept of a "continuum". We consider the continuum as a "relata", as a non-relational entity in relational physical reality.
To read the article correctly, you need to understand and accept a relational position in physics: Relational quantum mechanics, information-theoretical approach to the interpretation of QM, Qbism and similar ones. The paper is based on this point of view.
The idea is very simple, just a little unintuitive. I hope you enjoy it.Attachment #1: 1_Relational_physics_and_the_concept_of_the_continuum_300721.pdf
