News-Gazette (Feb. 12) -- A billion light years from Earth, two dense objects known as black holes collide at enormous speed, sending giant ripples through the fabric of space-time. Albert Einstein predicted such an event a century ago as part of his theory of relativity, and scientists have been searching for those ripples, known as gravitational waves, ever since. The announcement of their discovery sent waves of excitement around the globe Thursday, including at the National Center for Supercomputing Applications in Urbana, created 30 years ago to help scientists solve enormous computational puzzles like this one.
