Explanation:

Bodi West hills at Pattipuram near Devaram in Theni district. Here the Neutrino observatory will come up. A pioneer in the field of neutrino science, India was a world leader in 1965. In the mid-1990s, with the closing of the Kolar Gold Fields which was the site of the experiments, experimental neutrino research in India came to a halt, and the INO is expected to revive the lost advantage.

The three types of neutrinos, which were initially thought to be mass-less, are now believed to have a small mass. This was shown by observations of neutrino oscillation, which is a phenomenon by which one type of neutrino transforms into another.
