Fahrenheit -459: Neutron Stars and String Theory

DURHAM, N.C., Dec. 30, 2010 — Ultrachilled atoms trapped in a "bowl" made of laser light and then placed in a magnetic field have allowed scientists to measure the viscosity of a gas often considered to be the sixth state of matter. The measurements verify that this gas can be used as a "scale model" of exotic matter, such as superhigh temperature superconductors, the nuclear matter of neutron stars, and even the state of matter created microseconds after the Big Bang. The results may also allow experimental tests of string theory in the future. Duke physicist John Thomas made the viscosity measurements using...Read full article
