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

  • A new paper proposes that the Big Bang occurred inside a black hole formed by a gravitational collapse in a larger universe.
  • This black hole universe model arose to address the Big Bang singularity problem proved by Roger Penrose in 1965.
  • The model shows the collapse leads to a bounce inside the black hole, avoiding a singularity using general relativity and quantum mechanics without exotic physics.
  • It predicts slight positive spatial curvature, like Earth's surface, which future missions such as Euclid may confirm as evidence for a bounce origin.
  • This suggests we witness a cosmic cycle continuation inside a black hole rather than an absolute beginning, offering new insights on early universe mysteries.
