...cannot be accurate because the event that the LHC is trying to recreate already happens in nature. Particle collisions of an energy equivalent to those planned in the LHC occur when high-energy cosmic rays collide with the earth's atmosphere. What's more, some scientists believe that the Tevatron accelerator at Fermi National Accelerator Laboratory (or Fermilab) near Chicago has already created Higgs bosons without incident; the Fermilab scientists are now refining data from their collisions to prove the Higgs' existence.

Nielsen counters that nature might allow a small number of Higgs to be produced by the Tevatron, but would prevent the production of the large number of particles the LHC is anticipated to produce. He also acknowledges that Higgs particles are probably produced in cosmic collisions, but says it's impossible to know whether nature has stopped a great deal of these collisions from happening. "It's possible that God avoids Higgs [particles] only when there are very many of them, but if there are a few, maybe He let's them go," he says...
...once has been able to find the Higgs boson in the stream of debris emitted when two particles are smashed together at high speeds. Scientists at another CERN particle collider, LEP, felt they came close before the accelerator shut down in 2000. Scientists using the Tevatron accelerator at Fermilab near Chicago are still hoping to publish a discovery before CERN starts analyzing data later this year. Higgs says he is 90% sure that the LHC will find it, but he doesn't have the final word. "With all respect to our theoretician friends, experiments find out the truth," explains Tejinder...
...concentration of the energy (which is what matters for creating new and exotic particles) achieved by RHIC is much less than what Tevatron has been doing for many years,” Associate Professor of Physics Masahiro Morii wrote in an e-mail, alluding to a federally-financed accelerator west of Chicago...
...energy concentrators reached inside the Tevatron are child’s play on a cosmic scale. According to Morii, “the universe has its own ways of accelerating particles to energies that we experimental physicists can only dream...
