Existence of a limit to the refinement of physical theories

Determine whether there exists a fundamental limit to the refinement of physical theories in depth—i.e., whether the process of constructing ever-deeper theoretical descriptions of physical reality terminates—thereby establishing whether a final, exhaustive theory of fundamental physics exists.

Background

This paper discusses the notion of a “final theory” that would provide an exhaustive description of physical reality, from which all other physical theories emerge as approximations or limiting cases. The author notes that current accepted theories are considered approximate and raises the question of whether the deepening of physical theory can continue indefinitely or must terminate at some point. The text briefly mentions that any potential limit might be connected to Planck-scale physics, thereby motivating the inquiry.
