Strangelets do not exist on the Moon

Science : The Moon isn’t made of green cheese and almost certainly doesn’t harbor hypothetical particles called " strangelets ,” an analysis of lunar soil has shown. The result undermines a possible strangelet sighting a decade ago and strengthens the case that the bizarre particles, which protesters once feared might emerge from an atom smasher and consume Earth, don’t exist."I’m not surprised,” says Frank Wilczek , a theorist at the Massachusetts Institute of Technology (MIT) in Cambridge. “It would be a great discovery to find strangelets, but the theoretical case for them is pretty shaky.” Still, he says, “it’s not crazy” to look for them.
