The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a largescale
physics experiment and observatory to detect cosmic gravitational waves and to
develop gravitational-wave observations as an astronomical tool.
LIGO INDIA- INDIGO
INDIGO, or IndIGO (Indian Initiative in Gravitational-wave Observations) is a
consortium of Indian gravitational-wave physicists.
This is an initiative to set up advanced experimental facilities for a
multiinstitutional observatory project in gravitational-wave astronomy located at
Aundha, Hingoli, Maharashtra.
What’s the point of finding gravitational waves?
Well, gravitational waves give us another way to observe space. For example,
waves from the Big Bang would tell us a little more about how the universe
formed. Waves also form when black holes collide, supernovae explode, and
massive neutron stars wobble. So detecting these waves would give us a new
insight into the cosmic events that produced them.
Finally, gravitational waves could also help physicists understand the
fundamental laws of the universe.
