Carroll Proposes Universe Is Eternal With No Beginning at Big Bang

What was said

"I've long wondered about this, and I wrote a paper years ago now with a woman who was a graduate student of mine at the time, Jennifer Chen, where we proposed that the Big Bang was not the beginning of our universe. The universe can be eternal. It can last forever."

Sean Carroll presented his theory that the Big Bang was not the beginning of the universe, but rather one of many events in an eternal cosmos driven by quantum fluctuations in empty space. His model suggests a symmetric U-shaped structure where new universes continuously form in both temporal directions, each with its own arrow of time defined by increasing entropy.
