Unveiling the secrets of dark energy.(COMPUTING)(Brief article)

R & D, April, 2007

Lawrence Livermore National Laboratory (LLNL), Calif., and the Univ. of Chicago, III., have used their supercomputing expertise to take another step toward unveiling the secrets of dark energy. The scientists at the university's Center for Astrophysical Thermonuclear Flashes, with support from computer scientists at the U.S. Dept. of Energy's National Nuclear Security Administration, Washington, D.C., created a 3-D simulation of an exploding white dwarf star in extraordinary detail.

The simulation of an exploding 1 a supernova will enable astrophysicists to gain insight into dark energy--an unknown force pushing apart the cosmos--that accounts for two thirds of the cumulative energy in the universe. The LLNL scientists say it is vital to understand their output...
