Seven years after it was cleared and sanctioned funds, the Indian Neutrino Observatory is nowhere in sight. Even two and a half years after PM Narendra Modi batted for it, it is stuck in the web of political foolishness, bureaucratic red-tapism, and judicial tunnel vision. Following a complaint from the Department of Atomic Energy at a review meeting last week, the PM has done the obvious: he has tasked cabinet secretary PK Sinha to remove all bottlenecks in the country's most ambitious science project. The Neutrino Observatory would be set up in a 4,300-feet deep cave in Tamil Nadu's West Bodi hills on the border with Kerala. The Observatory would enable scientists to study atmospheric neutrinos which are massless particles. They are supposed to carry clues to some of the unsolved mysteries of the universe.
