very sci-fi for me
A new heavy ion accelerator, RHIC, has recently started operation in the United States. It aims to produce energy densities sufficient to produce a new phase of hadronic matter -- a Quark-Gluon Plasma. It may be that the inclusion of strange quarks (a strangelet) could achieve a lower energy state by reducing the Fermi energy. This led to a possible doomsday scenario, in which a negatively charged glob of strange quark matter might start to accrete normal nuclei, and in principle swallow up the Earth. This scenario has now been shown to be exceedingly unlikely.
and if it matters :wink:
