LIGO supercomputer upgrade will speed up groundbreaking astrophysics research

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. Researchers use this network, known as the LIGO Data Grid, to analyze the gravitational wave data.
