An international team of physicists led by Professor Enrique Gaztañaga of the Institute of Cosmology and Gravitation at the University of Portsmouth has questioned the idea that the Universe began with the Big Bang.
This new theory challenges the traditional Big Bang model by proposing that our universe was born inside a black hole from a previous universe.
Published in Physical Review D, the model uses Einstein–Cartan theory, which includes quantum "torsion" to prevent singularities. Instead of a singular beginning, the universe undergoes a "bounce" inside the black hole, expanding outward to become a new cosmos.
This bounce naturally explains both the early rapid expansion (inflation) and the current accelerated expansion (dark energy), without needing exotic new particles or fields.
The model also predicts a slightly curved, closed universe—something future space missions like ESA’s ARRAKIHS or NASA’s SPHEREx may be able to detect.
One of the most compelling predictions is that our universe could carry the spin of the parent black hole, potentially explaining why two-thirds of galaxies seem to rotate in the same direction.
If confirmed by future observations, this cosmic spin could be a key signature supporting the theory.
In essence, this bold idea reimagines our universe not as the beginning of everything, but as part of a cosmic cycle, where each black hole could spawn a new universe—each with its own evolution.
