Narendra Modi

Rajnath Singh

Correct Answer : Narendra Modi

Prime Minister Narendra Modi laid the foundation stone of multiple scientific projects worth more than Rs 5800 crore on 11th May 2023.

* One of the most significant projects is the Laser Interferometer Gravitational-Wave Observatory, the Prime Minister said, "LIGO-India will include us in one of the few countries to have such observatories in the world. It will give our students and scientists new and advanced opportunities."

* The LIGO-India, to be developed in Hingoli, Maharashtra, will be one of the handful Laser Interferometer Gravitational-wave observatories in the world.

* It is an extremely sensitive interferometer of 4 km arm length, the interferometers act as 'antennae' to detect gravitational waves.

* The LIGO-India will work in synchronization with two observatories operating in the United States; one in Hanford, Washington, and the other in Livingston, Louisiana.

* When LIGO-India is completed, it will join a global network of gravitational-wave observatories that includes Virgo in Italy and KAGRA in Japan.

What are Gravitational Waves : A gravitational wave is an invisible (yet incredibly fast) ripple in space. Gravitational waves travel at the speed of light (186,000 miles per second). These waves squeeze and stretch anything in their path as they pass by.

* Einstein predicted that something special happens when two bodies—such as planets or stars—orbit each other. He believed that this kind of movement could cause ripples in space.

* These ripples would spread out like the ripples in a pond when a stone is tossed in. Scientists call these ripples of space gravitational waves..
