MCM Research Notes No. 1: Physical Constants as Observational Quantities – Measurement versus Cosmological Extrapolation This publication is the first issue of the MCM Research Notes series and serves as a methodological introduction to the Monistic Continuum Model (MCM 10.1). The work does not challenge the experimental foundations of modern physics. Instead, it examines the distinction between direct observation and cosmological interpretation. Particular attention is given to physical constants such as the speed of light, Planck's constant, and the gravitational constant. MCM 10.1 fully accepts the experimentally observed constancy of these quantities. At the same time, it distinguishes between the direct measurement of a physical constant and statements concerning its validity throughout the entire cosmological past and future. The study introduces the concept of the cosmological epoch problem, emphasizing that all measurements are performed within a specific stage of cosmic evolution. It further examines the dynamics problem of physical constants, asking why invariant physical constants are observed within a universe that is itself understood as a dynamic and evolving system. The central methodological position of this work is that observation, interpretation, and cosmological extrapolation should be treated as distinct categories of scientific statements. From this perspective, the observed constancy of physical constants is not rejected but regarded as a legitimate subject of further scientific inquiry. This issue establishes the methodological foundation for subsequent publications within the MCM Research Notes series.
