Ok I'll provide a definitive answer as to why I believe there is a fundamental difference between what occurs in nature and what will occur in the lab.
The first collision will be similar to a cosmic ray collision. However further collisions occurring in each test will occur under increasing temperatures. The energy release of each individual collision will remain consistent, but the final collisions in the "experimental programme" will occur at "temperatures more than 100 000 times hotter than the heart of the Sun, concentrated within a minuscule space". This is not the temperature at which cosmic rays collisions take place in nature. They fail to qualify that in their safety statement.

Another of my lovely analogies. A doctor using a rectal thermometer versus a torturer using a red-hot poker on your bum.
