The Nobel Prize: A LIGO Q&A
A little more than a hundred years ago, Albert Einstein worked out a consequence of his new theory of gravity: Much like waves traveling through water, ripples can undulate through space and time, distorting the fabric of the universe itself.
Today, Rainer Weiss, Barry C. Barish and Kip S. Thorne were awarded the 2017 Nobel Prize in Physics for decades of work that culminated in the detection of gravitational waves in 2015—and several times since—by the Laser Interferometer Gravitational-Wave Observatory (LIGO).
Emily and Chris sat down with UMD physics professor Peter Shawhan, a member of the LIGO collaboration, to learn more about gravitational waves and hear a sliver of the story behind this year's Nobel Prize.

Deep within the ice covering the South Pole, thousands of sensitive cameras strain their digital eyes in search of a faint blue glow—light that betrays the presence of high-energy neutrinos.
More than 300 feet underground, looping underneath both France and Switzerland on the outskirts of Geneva, a 16-mile-long ring called the Large Hadron Collider (LHC) smashes protons together at nearly the speed of light. Sifting through the wreckage, scientists have made some profound discoveries about the fundamental nature of our universe.
But what if all that chaos underground is shrouding subtle hints of new physics? David Curtin, a postdoctoral researcher at the Maryland Center for Fundamental Physics here at UMD, has an idea for a detector that could be built at the surface—far away from the noise and shrapnel of the main LHC experiments. The project, which he and his collaborators call MATHUSLA, may resolve some of the mysteries that are lingering behind our best theories.
