"Researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) have found evidence of gravitational waves, a key feature of standard models of how the universe works."
In relation to the big announcement from the LIGO collaboration on Thursday February 11, 2016, CCAPP Postdoc Paul Sutter composed an article describing the physics and importance of gravitational waves.
"In general relativity, space-time is dynamic...It can warp and twist, and bend and flex. It can wave. It responds to the presence of matter and energy, and can influence the behavior of that same matter and energy, exactly as you can. Space-time is a thing."
