The National Science Foundation (NSF) announced yesterday the detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) which consists of a pair of ground-based observatories in located in Hanford, Washington, and Livingston, Louisiana.
It was Albert Einstein who predicted the existence of gravitational waves in his general theory of relativity.
A panel of researchers from Perimeter Institute for Theoretical Physics discussed the meaning and implications of LIGO's announcement regarding the search for gravitational waves.
The panel included Perimeter Director Neil Turok, along with faculty members Asimina Arvanitaki, Latham Boyle, and Luis Lehner. Science journalist Kate Lunau moderated the discussion.
