Minnesota-Made Supercomputer Used in Historic Experiment

BURNSVILLE, Minn. (AP) — A Minnesota supercomputing company has a role in the research that's being heralded as one of the biggest discoveries in the history of physics — the sound of gravitational waves.

When scientists captured the sound of two black holes colliding in space, they did it with a system of supercomputers designed and built by Nor-Tech of Burnsville.

The Star Tribune says the company has been working with the University of Wisconsin-Milwaukee and California State University, Fullerton for a decade on the cluster that made the detection of the gravitational waves possible.

The news announced by scientists Thursday exhilarated astronomers and physicists who will now be able to hear the soundtrack of the universe and listen as violent collisions reshape the cosmos. It confirms a theory that Albert Einstein predicted a century ago.
