Time Hypothesis

This paper introduces a hypothesis about the nature of time, proposing that it is not a universal background parameter, but rather an internal and interactive property of physical systems. Each system has its own intrinsic time, which may remain hidden or latent until it interacts with another system. From this interaction arises an effective time, defined as a coupling of internal times and described mathematically as a harmonic mean. This effective time governs observable dynamics and provides a bridge between classical, relativistic, and quantum regimes.
