Our universe is expanding at an ever-accelerating rate — a phenomenon that all theories of cosmology agree upon but none can fully explain. Now, a new theoretical study offers an intriguing solution: Perhaps our universe is expanding because it keeps colliding with and absorbing"baby" parallel universes..
, scientists proposed the idea that the expansion of the universe may be driven instead by constantly merging with other universes. The scientists also computed the rate of expansion of the universe using their theory, and their calculations more closely fit with observations of the universe than the traditional Standard Cosmological Model, the researchers said.An illustration of the Euclid spacecraft scanning the sky. Euclid's mission is to hunt for traces of dark matter and dark energy in the ancient universe, to help explain the mysteries of cosmic expansion.
"The fact that the Universe has expanded … in a very short time, invites the suggestion that this expansion was caused by a collision with a larger universe, it was really our Universe which was absorbed in another 'parent' universe," the researchers wrote in their paper.
