I am not going to argue this from the perspective of logic, but rather physics. The grand symmetry of the universe is a set of transformation on a vacuum state that keeps it a vacuum. The vacuum is as close to nothing as we can find in physics at this time. The grand symmetry, which I think is

My tendency is to say that wormholes do not exist. There are problems with these types of solutions. The biggest is they requires a source term that has negative energy or T^{00} < 0. This would mean the quantum field that defines this source is not bounded below. This means an infinite well
