On Explaining Everything

This work explores foundational issues related to many-worlds theories in Cosmology. It is argued that the metaphysical picture drawn by these theories arise from metaphysical assumptions made during their formulation—most of which are problematic. I elucidate the nature of these assumptions and examine their legitimacy. I conclude the metaphysical presuppositions responsible for the apparent reliability of many-worlds theories in Cosmology are unmotivated and unwarranted by evidence. On this basis, the questions many-worlds models in Cosmology attempt to solve turn out to be a non-starter because their presupposed metaphysical grounding is ill-founded.
