What does LIGO mean in OBSERVATORIES
LIGO stands for Laser Interferometer Gravitational-Wave Observatory. It is an observatory that uses laser interferometry to detect gravitational waves emitted from astrophysical sources such as the merging of two black holes or neutron stars in our universe. The observatory consists of two 4 kilometer long arms that form an “L” shape, and at the end of each arm are mirrors that send and reflect the laser back along the same path. When a gravitational wave passes through, it stretches and compresses space-time which alters the path of the beams of light sent out from the lasers - this slight difference is then detected by the scientists studying them. LIGO has revolutionized astrophysics and proved Einstein's predictions about spacetime right - opening up a new window into astronomy!

Essential Questions and Answers on Laser Interferometer Gravitational-Wave Observatory in "MISCELLANEOUS»OBSERVATORIES"
What is LIGO?
LIGO stands for Laser Interferometer Gravitational-Wave Observatory. It is a large-scale physics experiment that utilizes lasers and interferometers located in the United States to detect faint ripples in the fabric of spacetime known as gravitational waves.
How does LIGO work?
LIGO consists of two massive detectors, one located in Livingston, Louisiana and the other located in Hanford, Washington. Each detector contains two perpendicular arms of 4 kilometers (2.5 miles) long. A laser beam is sent along each arm and reflected off of a mirror at the end back to the beginning where it is split into two beams which travel back along the arms before being recombined at a common detector. Any imperfection or disruption in spacetime will cause slight differences between how the two beams interacted at their point of recombination, allowing scientists to detect these extremely small disturbances known as gravitational waves.
Who invented LIGO?
The idea behind the concept of Laser Interferometer Gravitational Wave Observatories was first proposed by Caltech's Professor Rai Weiss in 1967. Then over several decades until its launch, numerous physicists worked on developing the necessary technology and instruments needed for this ambitious project including co-founders Professor Kip Thorne and Rainer Weiss from MIT, Ronald Drever from Caltech, as well as Barry Barish and David Hahn who took part in leading roles during its construction.
When did LIGO become operational?
The Laser Interferometer Gravitational-Wave Observatory became fully operational on Sep 18th 2015 when it detected its first detections referred to as GW150914 and GW151226, marking an incredible milestone in modern science history by proving Einstein's theory on General Relativity which had eluded humanity for nearly 100 years since its initial theoretical prediction!
What has been discovered using LIGO?
Since its activation in Sep 2015, several groundbreaking discoveries have been made using the data obtained by LIGO such as black holes merging with one another, binary neutron stars crashing into each other emitting powerful gamma rays across space & time! All these findings have indeed helped revolutionize our understanding of gravity & physics today!
Who funds LIGO?
Funding for Laser Interferometer Gravitational Wave Observatory comes from a variety of sources ranging from public funding from countries like USA (National Science Foundation NSF) & UK (Science & Technology Facilities Council STFC), to private donations from institutions such as Microsoft Research Ltd., Sherman Fairchild Foundation etc., and charitable bodies like National Geographic Society & Heising Simons Foundation.
Is there a timeline for any future observations?
Absolutely! Starting 2021, another major upgrade called Advanced-LIGO Plus will be implemented which will increase the sensitivity level even further allowing us to observe even fainter ripples through spacetime than current levels! This should help us explore new areas of physics never previously accessible before!
Final Words:
In conclusion, LIGO stands for Laser Interferometer Gravitational-Wave Observatory – a powerful tool used to study phenomena across our Universe. Its importance lies not only in its ability to provide proof for Einstein's theories about gravity and spacetime, but also its capacity to expand our knowledge on some of astronomy's greatest secrets!
