A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have formed inside a colossal black hole residing in a larger, parent universe. The Big Bang theory, along with Einstein's general relativity, has successfully explained major cosmological phenomena, including the cosmic microwave background, the universe's large-scale structure, and its accelerating expansion often linked to dark energy.
Yet, fundamental problems remain with this theory, such as the unexplained nature of dark energy and dark matter, the singularity at the Big Bang, and inconsistencies between general relativity and quantum mechanics. "Most scientists have responded by proposing either a mysterious new form of energy — [called] dark energy — or by modifying the laws of physics," Enrique Gaztañaga, professor at the University of Portsmouth, told Space.com. "But these are drastic steps."
