Description
The nature of dark energy is one of the most pressing open questions in physics. While the standard ΛCDM model assumes a static cosmological constant, alternative approaches suggest a dynamical scalar field as the source of cosmic acceleration. In this work, we propose a shockwave-driven model, where dark energy emerges as a high-energy vacuum excitation of a gravitationally coupled scalar field. This model suggests that metric fluctuations, quantum gravitational backreaction, and vacuum polarization dynamically alter the effective energy density of the universe, explaining the observed acceleration. Using a modified field-theoretic approach, we derive the time-dependent equation of state for dark energy, demonstrating how it naturally resolves the Hubble tension and predicts observable deviations from ΛCDM cosmology. This framework provides a testable link between quantum field fluctuations and large-scale structure formation, with potential constraints from CMB anisotropies, galaxy surveys, and gravitational wave experiments. If validated, this approach could provide a first-principles explanation for the dark energy problem, bridging cosmology, quantum gravity, and high-energy physics.
