"Universe Merging: The Theory of Expansion Through 'Baby Universes'"

Astronomers have proposed a new theory suggesting that our universe's accelerating expansion may be driven by merging with smaller "baby" universes, rather than solely by dark energy. The study's mathematical model offers a potential explanation for the universe's expansion and aligns more closely with observations than the Standard Cosmological Model. The researchers also suggest that early cosmological inflation may have been caused by our young universe colliding with a larger universe, leading to the absorption of "baby" universes.
