The Laser Interferometer Gravitational-Wave Observatory is a large-scale physics experiment and observatory to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool.
The three most prominent physical differences between LIGO, a gravitational wave observatory, and astronomical observatories- First - LIGO is blind, Second - LIGO is the opposite of round. , Third - LIGO cannot function alone.
LIGO operates two gravitational wave observatories in unison: the LIGO Livingston Observatory (30°33′46.42″N 90°46′27.27″W) in Livingston, Louisiana, and the LIGO Hanford Observatory, on the DOE Hanford Site (46°27′18.52″N 119°24′27.56″W), located near Richland, Washington.
LIGO’s arms are so long that the curvature of the Earth is a measurable 1 meter (vertical) over the 4 km length of each arm.
Construction of LIGO's original gravitational wave detectors was completed in 1999.
Length: 4,000 m (13,123 ft 4 in) , Wavelength: 43–10000 km; (frequency 30–7000 Hz)
LIGO will be used for research into the nature of gravity, and it will open up an entirely new window onto the universe. It will thus be a scientific tool both for physics and for astronomy.
The gravitational waves detected by LIGO on that fateful day were generated by two black holes colliding and merging into one nearly 1.3 BILLION light years away!
LIGO-India, or INDIGO, is a planned collaborative project between the LIGO Laboratory and the Indian Initiative in Gravitational-wave Observations (IndIGO) to create a world-class gravitational-wave detector in India
LIGO is designed to detect a change in distance between its mirrors 1/10,000th the width of a proton! This is equivalent to measuring the distance to the nearest star to an accuracy smaller than the width of a human hair!
