strangelet
n.— «But Wagner and Sancho’s court papers raise theoretical scenarios in which the LHC could create particles that gobble up the Earth, such as “killer strangelets.” Strangelets are hypothetical blobs of matter containing “strange” quarks, as well as the usual “up” and “down” types that make up ordinary matter.» —“Particle smasher ‘not a threat to the Earth’” by Hazel Muir New Scientist Mar. 28, 2008.
