...conditions in RHIC could produce a strangelet disaster, physicists argue, then we would probably be dead already...
...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...
Gabrielse said that high-energy collisions that could be produced inside RHIC already occur—naturally—on the lunar surface. “There have been highly energetic cosmic rays colliding with the moon for a long time, and these sorts of things don’t seem to have happened,” Gabrielse said...
...moon will tend to scatter the nuclei that it hits, making it less likely that they will clump”—and thus produce strange matter—“than if the collision were head on,” as it would be inside RHIC. So, the fact that the moon has existed for 4.5 billion years without condensing into a tiny ball does not necessarily refute Posner’s argument...
...Harvard physicists’ rejection of Posner’s calculation suggests the risk of catastrophe posed by RHIC might fall within a margin that most of us would be willing to tolerate...
