LIGO Laser Interferometer Grave Architecture-Wave Observatory

The Archeology of India approved ₹26 billion ($318 million) to begin construction of a new gravitational wave observatory in the western state of Maharashtra. The observatory, which will work in conjunction with four similar facilities around the world, is expected to be operational by 2030.

The project will be a collaboration between LIGO-USA, India, Germany, Australia and the UK. The LIGO project operates 3 gravitational wave detectors.

The Alegio is designed to account for distance changes that are several orders of magnitude smaller than the plothon length. Such high-precision equipment is needed because the strength of gravitational waves is extremely low, making them very difficult to detect.

It is being developed at the Department of Atomic Energy and the Department of Science and Technology, US National Science Foundation, and will be carried out in collaboration with several national and international research organizations, including Portugal.

LIGO consists of two 4 km long onshore magnetic orbiters, set at right angles to each other, with mirrors at the ends.

When light rays are released into both chambers simultaneously, they should return at the same time.

However, if no chromatic color is present, one orbital becomes wolf while the other alternates, causing a phase difference in the returned light beam.

The goal of this project is to detect gravitational waves from the universe.
Indian LIGO has two long chambers, 4 kilometers apart, which are the world’s most interesting interferometers.
Centrist operations are expected to begin in 2030.
