Phase Change of the Universe?? I was listening to Coast to Coast radio this morning on the way to work and they had some scientist on who was saying that the when the CERN particle accelerator is turned on in November 2007 one of its main goals is to find the Higgs Boson particle. However, he went on to say that some scientists fear that when we do this we may cause a phase change in the Universe since we are trying to approximate the conditions an instant after the big bang. Apparently, at the energy levels the accelerator will see, it may cause a chain reaction type event. Although a low probability he said it is still a risk because we are going into uncharted waters. The scientist went on to say that we would not even know it happened because we would die instantly as the Universe instantly changed. This is the first time I heard of this concern. Any thoughts?
