The scientific journal, Science, has chosen as its 2016 Breakthrough of the Year the discovery of tiny ripples in spacetime called gravitational waves – a finding that confirmed a century-old prediction by Albert Einstein. LSU faculty and graduate students are part of the 1,000-member LIGO Scientific Collaboration responsible for the discovery. LSU Department of Physics & Astronomy Professor Gabriela González serves as the spokesperson for the LIGO, or Laser Interferometer Gravitational-wave Observatory, international collaboration.
