String Theory and Big Bang in a 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.

String theory is an active research framework in particle physics that attempts to reconcile quantum mechanics and general relativity.^[1] It is a contender for a theory of everything (TOE), a manner of describing the known fundamental forces and matter in a mathematically complete system.
