Here is Yahoo! News reprinting a Reuters story on the Laser Interferometer Gravitational-Wave Observatory (LIGO) and its recent announcement that it had detected a third gravitational wave signal. This particular ripple through space and time originated from a black hole collision approximately 3 billion light-years from Earth. Georgia Tech researchers are well-represented within LIGO, and Laura Cadonati, professor in the School of Physics, is the international research team's deputy spokesperson.
