Conceptual analysis explores the divergence of observer and time definitions in relativity and quantum mechanics, suggesting a new ontological framework.
As the two pillars of modern physics, relativity and quantum mechanics have both achieved overwhelming experimental success in their respective domains, yet they have never realized self-consistent unification at the underlying logical level. Most existing studies focus on the mathematical technical difficulties of quantum gravity, while generally neglecting the structural divergence of the core concepts of "observer" and "time" between the two theories. Through conceptual analysis and logical tracing, this paper points out that the observer in relativity is essentially a massless geometric coordinate marker with no intrinsic clock, which only undertakes the functions of event marking and reference frame mutual translation. It belongs to the object level concept within the classical world, and can be summarized as the translator of the ready-made world. The observer required by quantum mechanics is a physical entity that can trigger wave function collapse and carry the time metric benchmark. It is the logical premise for the generation of the observable classical world, belonging to the meta-level concept, and can be summarized as the legislator of the real world. The divergence between the two is not an isolated terminological difference. Its deep root lies in the completely heterogeneous presuppositions of the two theories on "time": time in quantum mechanics is a transcendental, uniform global background parameter "before the birth of clocks", that is, a "logical concept before measurement"; time in relativity is a local, operable relative metric result "after the birth of clocks", that is, a "logical concept of the classical deterministic motion world". As physical theories both belonging to the principle theory paradigm, both actively skip the construction of the physical ontology of time and directly presuppose the functional role of time, which eventually leads to the double logical dislocation of observer and time concepts. Relativity lacks the "first chapter" of deriving observers from the vacuum substrate, and quantum mechanics lacks the physical carrier definition of observers, which are essentially two manifestations of the same ontological gap. Metretics Dynamics (MD; formerly Time Field Theory, TFT) takes the scalar time field as the only physical ontology, defines mass as the local condensed state of the time field, and deduces the ontological proposition that "mass is the observer". It eliminates the absolute division between meta-level and object level from the ontological level, and reduces "global background time" and "local relative time" to the apparent forms of the same physical field under different condensation degrees. The continuous unitary evolution of the wave function corresponds to the uniform rhythmic flow of the time field in its diffuse state, while wave function collapse is essentially a local state mutation of the time field when coupled with a macroscopic mass condensate. Both processes are unified under the intrinsic dynamical laws of the time field. Within a unified framework, it simultaneously accommodates the metric anchor of quantum measurement and the coordinate mutual translation mechanism of relativity, providing a constructive ontological path for the conceptual compatibility of the two major theories.
