He is a cosmologist of international repute and best known for his work on the conformal gravity theory, together with his mentor Fred Hoyle. He also set up the Inter-University Centre for Astronomy and Astrophysics in Pune. More recently, he was involved in an effort to sample air from the atmosphere at heights of 41km for microorganisms. This study reported at least two strains of bacteria and one fungus that were cultured in the lab. If these findings hold up to further enquiry, they provide a new perspective on life on earth and its beginnings. (en) |
