Gravitational Waves

In Recent times, Gravitational Waves have been in the news, even the noble award this year was given for the contribution towards discovery of Gravitational Waves. India has also decided to go for LIGO (Laser Interferometer Gravitational Wave Observatory) Projects.

Gravitational waves were first proposed by Einstein as part of theory of relativity. These are like the repulse created in the fabric of space and time. Whenever we move mass, we always get Gravitational Wave. When these wave pass through earth, the earth also vibrates but this vibration is very minute and we need advanced equipment to figure out these vibrations.

Such equipment is LIGO, it consists of two long laser tubes perpendicular to each other, when earth vibrates these laser tube create interference at center which can be used to study the Gravitational Waves.

Gravitational waves can travel throughout the universe without any obstruction. Hence, they can give picture of the universe which we have not seen. This may lead to rise of entirely new branch of astrophysics.

LIGO India will add to ability of the scientists about being more accurate towards the study of Gravitational waves. It will give scientific training to Indian scientists on the international parameters.

LIGO India project will be mainly conducted by three institutions in India. Which are as follows:

  • Institute of Plasma Research, Gandhinagar, Gujrat.
  • Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune.
  • Raja Ramanna Centre for Advanced Technology, Indoor.
