What is in the News ?
- The Union Cabinet on Thursday approved a project to build an advanced gravitational-wave detector in Maharashtra at an estimated cost of Rs 2,600 crore.
- The facility’s construction is expected to be completed by 2030.
Gravitational Waves
- Gravitational waves are ripples in the fabric of space and time that travel at the speed of light.
- They are created by the motion of massive objects, such as black holes or neutron stars, which generate gravitational waves when they orbit or collide with each other.
- According to Albert Einstein’s theory of general relativity, any object with mass warps the space-time around it. When two massive objects orbit each other or collide, they produce ripples or waves in space-time that propagate outward at the speed of light.
- Gravitational waves are extremely weak and difficult to detect. They were first directly detected by the Laser Interferometer Gravitational-Wave Observatory (LIGO) in 2015, a century after they were predicted by Einstein’s theory.
LIGO-India
- It shall be built in Hingoli district, Maharashtra.
- It shall be built by Department of Atomic Energy and the Department of Science and Technology with an MoU with the U.S. National Science Foundation.
