String theory researchers simulate big-bang on supercomputer

(PhysOrg.com) -- A trio of Japanese physicists have applied a reformulation of string theory, called IIB, whereby matrices are used to describe the properties of the physical universe, on a supercomputer, to effectively show that the universe spontaneously ballooned in three directions, leaving the other six dimensions tightly wrapped, as string theory has predicted all along. Their work, as described in a paper pre-published on the arXiv server and soon to appear in Physical Review Letters, in effect, describes the birth of the universe.
