In 2016, an international team of scientists found definitive evidence--tiny ripples in space known as gravitational waves--to support one of the last remaining untested predictions of Einstein's theory of general relativity. The team used the Laser Interferometer Gravitational-Wave Observatory (LIGO), which has since made several gravitational wave discoveries. Each discovery was possible in part because of a global network of supercomputer clusters, one of which is housed at Penn State. Resear...
