Scientist Baldevkrishan Sharma’s theory of Natural Universe Expansion (NUE) revolutionizes our understanding of cosmic acceleration. Unlike standard models that depend on hypothetical "dark energy," NUE offers a mathematically grounded alternative. This model introduces the Nu Constant, incorporating time as a dynamic factor in cosmic expansion. Sharma’s 25-year research challenges Hubble’s Law and Big Bang Theory, opening fresh pathways for astrophysical exploration.
