Does modern science describe one unified physics or multiple frameworks?

As we delve into foundational theories, a recurring point of debate emerges. I’m trying to reconcile the grand promise of a "Theory of Everything" with the pragmatic reality of our highly effective but separate models. It feels like we have different rulebooks for different scales of reality.

In my experience, the situation is nuanced. Operationally, we work with multiple, brilliantly successful frameworks quantum field theory for particles, general relativity for cosmology. I have seen promising bridges, like string theory, but they remain computationally detached from experimental verification. Currently, physics is a patchwork of domain-specific "laws." I would recommend viewing unification not as a description of current practice, but as a profound guiding motive that drives the field forward, even as we rely on our best-fit models for now.
