What if the Big Bang Wasn't the Beginning? Research Suggests It May Have Taken Place Inside a Black Hole

  • A new model proposes that the Big Bang occurred inside a black hole formed by a gravitational collapse rather than as a singular beginning.
  • This idea arises from the limitations of the Big Bang model, which begins with a singularity where physics breaks down, a problem proven by Roger Penrose in 1965.
  • The model shows gravitational collapse can lead to a bounce inside the black hole, producing expansion phases using only general relativity and quantum mechanics without speculative physics.
  • It predicts slight positive spatial curvature in the universe, which ongoing missions like Euclid may confirm, offering a testable sign of the bounce origin.
  • This black hole universe concept suggests the cosmos is a continuing cycle shaped by gravity and quantum mechanics, providing new insight into cosmic mysteries and our place in the universe.
