A team of physicists says there may be another universe running backward in time prior to the Big Bang:
Scientists, led by University of Edinburgh professor Neil Turok, have a new theory about how our universe operates. They say that another universe may have existed before the Big Bang, moving in reverse through time.
They call it the "anti-universe," and it's basically a reflection of our own with oppositional time.
The paper was accepted for publication in the journal Annals of Physics.
This elegant idea could help explain some of the biggest mysteries in cosmology, including the imbalance between matter and antimatter and the nature of dark matter, while offering an alternative to prevailing theories Turok describes as overly complex.
The theory builds on the concept of symmetry in physics, where particles, forces, and even time have mirrored opposites.
However, our universe appears lopsided — time moves only forward, and particles outnumber their antimatter counterparts. Turok's "mirror hypothesis" restores that balance, envisioning a universe that mirrors ours in perfect symmetry. "The progress we have already made convinces me that there are alternatives to the standard orthodoxy," Turok said, urging cosmology to break free of its current constraints.
