"They *did* say that collisions like these happen often in nature. They didn't say these temperatures, the quark gluon plasma, etc occurred as well, because given the information that the collisions produce these conditions and that the collisions occur in nature, it should be unnecessary for them to do so."
They didn't say these collisions produce QGP in nature, nor has any other physicist nor have you produced supporting evidence to support it. It's the same tired argument used throughout this thread. I took the time earlier to investigate where QGP does occur and could only find it theoretically existing in the core of neutron stars. Please take the time to find a reliable source indicating that these collisions produce QGP in nature and I will happily apologize for my mistake. Until then rehashing the same line provides no new material for discussion.
