%0 Journal Article %T Will relativistic heavy-ion colliders destroy our planet? %A Arnon Dar %A A. De RšČjula %A Ulrich Heinz %J Physics %D 1999 %I arXiv %R 10.1016/S0370-2693(99)01307-6 %X Experiments at the Brookhaven National Laboratory will study collisions between gold nuclei at unprecedented energies. The concern has been voiced that ``strangelets''-hypothetical products of these collisions - may trigger the destruction of our planet. We show how naturally occurring heavy-ion collisions can be used to derive a safe and stringent upper bound on the risk incurred in running these experiments. %U http://arxiv.org/abs/hep-ph/9910471v1
