University Teams Challenge Big Bang Theory with New Cosmological Models

Recent scientific research is challenging the traditional Big Bang theory of the universe's origin. A team from the University of Bonn suggests that the cosmic microwave background radiation, a key evidence for the Big Bang, may have been significantly overestimated or might not exist at all, which could force a fundamental reconsideration of cosmology. Meanwhile, researchers at the University of Portsmouth propose an alternative 'Black Hole Universe' theory, where our universe formed from the rebound of matter inside a massive black hole within a larger parent universe, avoiding the singularity problem of the Big Bang. This model aligns with both general relativity and quantum mechanics and offers a testable framework, suggesting cosmic creation as a cyclical bounce rather than a singular explosion. These findings highlight a growing scientific debate and indicate that our understanding of the universe's beginning may be evolving beyond the traditional Big Bang narrative.
