• Resumen

  • The article presents research on how the hot early universe or colliding neutron stars may have created so-called strange quark matter, an extremely dense mix of up, down and strange quarks. Because a strange nugget would far outpace sound underground, seismographs would record it as a simultaneous tremble from many points along a line. Careful sifting through one million seismic reports between 1990 and 1993 revealed one set of reports from November 1993 that has the right properties for a nugget strike, say Vigdor L. Teplitz and his colleagues at Southern Methodist University.
