Could there be a looming vacuum catastrophe waiting to happen? Is the universe doomed? This is related to the Higgs boson and the heaviest fundamental particle we know of, the top quark. All systems tend to minimize energy. Just as in the case of atoms forming molecules to lower overall energy of the system, particles also have a propensity to lower their potential energy. A very simply potential energy diagram looks like a simple parabola. The Y axis is potential energy, and the X axis represents a parameter by which potential energy varies, such as position, energy, and field value. There's a minimum, or lowest point at 0 energy on the x-axis. What if we had two minima, where one minimum was at a higher energy state than the other minimum. A physical system trying to minimize energy would always seek to fall into the lowest possible minimum. But the key is that in order to do this, it has to overcome the barrier. This is the classical picture of how potential energy works. But the world is fundamentally quantum mechanical, not classical. The Heisenberg’s un
