The Influence of Dark Matter Interactions on the Fundamental Constants of Physics

Abstract: Dark matter is traditionally modeled as a non-interacting component of the universe, influencing astrophysical structures only through gravity. However, emerging theories suggest that dark matter may interact weakly with standard model particles or even affect the fundamental constants of nature, such as the fine-structure constant (α), the gravitational constant (G), and the electron-to-proton mass ratio (μ). This paper explores the possibility that dark matter interactions subtly modify these fundamental constants over cosmic timescales or in high-density astrophysical environments. We analyze potential variations in α, G, and μ using constraints from quasar spectral lines, atomic clock comparisons, and big bang nucleosynthesis (BBN) data. Additionally, we investigate how dark matter couplings to scalar fields, extra dimensions, or unknown bosonic mediators could induce local or large-scale variations in fundamental constants, leading to observable deviations in gravitational waveforms, cosmological evolution, and precision tests of atomic physics. Key Highlights: Theoretical models linking dark matter to the evolution of fundamental constants. Experimental constraints from atomic clocks, astrophysical spectroscopy, and BBN. Implications for cosmology, including early universe physics and structure formation. Potential gravitational wave signatures of dark matter-induced variations in G. New predictions for laboratory and space-based precision tests of fundamental physics. By integrating cosmological data, quantum field theory, and high-precision laboratory measurements, this paper explores the potential of dark matter as a driver of fundamental physics evolution, offering testable predictions for future observations.
