Video Information

All right, let's go. Number seven, the false vacuum collapse already in progress.
In 1980, physicists Sidney Coleman and Frank De Luccia published a paper in Physical Review D that introduced a concept most people have never heard of, but that keeps cosmologists awake at night. They proposed that the universe might not exist in its lowest possible energy state. Instead, reality could be sitting in what they called a false vacuum, a temporary configuration that appears stable but is actually one quantum fluctuation away from catastrophic collapse.
