"Hut and Rees,[8] however, have determined that because we had observed cosmic ray collisions at much higher energies than those produced in terrestrial particle accelerators, that these experiments will not, at least for the foreseeable future, pose a threat to our vacuum. Particle accelerations have reached energies of only approximately four thousand billion electron volts (4 ×103 GeV). Cosmic ray collisions have been observed at and beyond energies of 1011 GeV, the so-called Greisen-Zatsepin-Kuzmin limit. John Leslie has argued[9] that if present trends continue, particle accelerators will exceed the energy given off in cosmic ray collisions by the year 2150.
This event would be contingent on our living in a metastable vacuum, an issue which is far from resolved.[10] Worries about the vacuum metastability event are reminiscent of the controversy about turning the Relativistic Heavy Ion Collider on."
Eszerint legalabb 2150-ig egeszen bizonyosan biztonsagban van az Univerzum az embertol. :-) Utana meg ..... hat azt nem tudjuk.
