The Quantum Bounce: Universe Emerged From Dying Twin

Until very recently, asking what happened at or before the Big Bang was considered by physicists to be a religious question… But in the past few years, a new theory called Loop Quantum Gravity (LQG) has emerged. The theory suggests the possibility of a “quantum bounce,” where our universe stems from the collapse of a previous universe. Yet what that previous universe looked like was still beyond answering.

Now, physicists Alejandro Corichi from Universidad Nacional Autónoma de México and Parampreet Singh from the Perimeter Institute for Theoretical Physics in Ontario have developed a simplified LQG model that gives an intriguing answer: a pre-Big Bang universe might have looked a lot like ours.

Before the Big Bang: A Twin Universe?

  1. This simply forces the theme of Ronald Moore’s reimagined Battlestar Galactica to resound in my head: “This has all happened before, and will all happen again.”

    I’ve seriously wondered about this for years, “The Infinite Universe Loop”.

    Did this evil twin universe sport a waxed moustache?

    Isn’t that what Galactus is supposed to do when he’s finished eating?

    Robert J. Sawyer, “Calculating God”. Utterly fascinating SF book. Running in the background from about halfway on is the idea that the universe is periodically reborn in a series of Big Bangs and Big Crunches. It’s cool to see some real-life science backing this up.

    Liam — this IS the origin of Galactus. Seriously, did these physicists use issues of the Fantastic Four as textbooks when they went to school?
