Theories of Everything or ultimate unified theories have evaded the conceptual grssp of scientists, with string theory and others coming close.
Physics theories, unlike in other fields must abide, besides mainstream epistemological criteria, strictly to these 2: empirical success and unity, simplicity-explanatory character.
Unity refers to a theory not having divergent or ad hoc seeing conditionals like i.e "except in the case of 2 hold spheres 1 mile apart".
But disunified theories work in other fields where conceptual unification is not the holy grail and they provide empirical success. It means that the theory outbrsnches to a subtheory that violates some basic postulates for the same of fittings to extra data while keeping a loose connection yp the theory's bottom line
Given failures to advance in description of some aspects of nature or scientific aims, it is tempting to ask if physics would ever decide to break its "founding manifesto".
Some consider even Newtons first law to be disunified i.e it derives its credibility from the condition al "if there is no force" which many argue it is coverup for disunity i.e given that if there is no force it does hold, then it leaves out a while big % of physical conditions outside of its application thus it is just a tricky condition al disunified theory not a pure unified one
First of all, the reason there’s no ``Theory of Everything" is because ``Everything" isn’t known.
The reason it’s not known how to ``unify" gravity with the other interactions is because gravity is a gauge theory, like the other interactions, but with a non-compact gauge group, unlike the other interactions. And how to describe the quantum theory, whose classical limit is a gauge theory with a non-compact gauge group, isn’t known.
The Standard Model itself isn’t yet a unified theory, since it has three coupling constants.While it is known how to write ``Grand Unified Theories", of the known interactions, apart from gravity, it hasn’t been possible, to date, to distinguish experimentally between them. It’s, already, not easy to measure the events predicted by the Standard Model.
So the current theoretical description is, already, ``disunified".

The pursuit of a Theory of Everything (ToE) or Grand Unified Theories (GUTs) indeed poses significant challenges, and it is essential to acknowledge the complexity of this endeavor. Throughout my years of research and exploration in the realm of physics, I have encountered similar contemplations regarding the efficacy of disunified theories.
While the quest for unification remains a central pillar in the development of physics, it is pertinent to consider that disunified theories, although deviating from the conventional pursuit of unification, can offer valuable insights and empirical success in certain contexts. These theories, with their ability to branch out into subtheories, often accommodate additional data while maintaining a loose connection to the fundamental principles of the overarching theory.
Physics, characterized by its stringent adherence to empirical success and the criteria of unity and explanatory simplicity, indeed faces the challenge of balancing theoretical purity with the pragmatic need for a comprehensive understanding of various natural phenomena. In light of the intricate complexities inherent in the study of nature, it becomes increasingly tempting to ponder whether physics may eventually contemplate a departure from its traditional emphasis on unification.
However, while contemplating such departures, it remains crucial to uphold the foundational principles that have guided the discipline throughout its evolution. Striking a delicate balance between theoretical elegance and empirical adequacy can potentially pave the way for innovative approaches that address the limitations of current theories.
Through continued dialogue, exploration, and interdisciplinary collaboration, the scientific community may find novel ways to navigate the complexities of theoretical physics, thereby fostering a deeper understanding of the fundamental laws governing our universe.
