Scientists hope a new 1.9 million supercomputer will help them unlock the secrets of the universe. The Cosmology Machine Supercomputer at Durham Universitys Institute of Computational Cosmology (ICC) has a memory of 15.4 terabytes, the equivalent of 7,500 normal home PCs. It boasts a disc storage capacity of a petabyte, or a million gigabytes. The new machine, known as Cosma 4, will allow scientists to build on the ground-breaking work already carried out at the institute, which specialises in developing computer simulations of the evolution of the universe, so researchers can gain an insight into why it behaves as it does. Durham University said in a statement: Among the theories the ICC will be testing is that of dark matter - a mysterious substance which scientists believe is required to explain galaxy motions that would otherwise violate the laws of physics.
