The triangular universe
Article Abstract:
The casual dynamical triangulation (CDT) method is emerging as a promising approach to solving the problems in physics like unifying the laws of gravity with those of quantum mechanics. The CDT has constructed spacetime geometries from simple triangular structures and they have generated model universe, which can reproduce features seen in standard cosmological theories, such as the expansion and contraction of space overtime.
