TRUE 6.1 – Rethinking Cosmic Expansion (Public-oriented Document – Version 1.1 – EN)

Public-oriented AbstractFor the past twenty-five years, the standard cosmological model (ΛCDM) has explained the accelerating expansion of the Universe by invoking a mysterious “dark energy,” assumed to be constant and to account for nearly 70 % of the cosmos.However, recent studies (Shajib & Frieman, 2025) suggest that its effect has decreased by about 10 % over the last billion years.The TRUE 6.1 framework, derived from the Universal Redistributive Theory (TRU), offers a different perspective:what we call “cosmic acceleration” would be the manifestation of a global imbalance that is now relaxing, quantified by a parameter κ(t).When κ is high, expansion is accelerated; as κ decreases, expansion slows and approaches the ordinary gravitational pace.TRUE 6.1 agrees with local observations (Type-Ia supernovae, BAO, H(z)) but predicts measurable deviations at high redshift (z > 1) and foresees the current acceleration as transient, not eternal.This vision avoids invoking an exotic force and provides a more natural and testable interpretation of the cosmos.
