Yukio Tomozawa obtained DSc in 1961 from Tokyo University. He was Assistant at Tokyo University (1956- ), and at Tokyo University of Education (1957-1959): Member at the Institute for Advanced Study, Princeton, NJ (1964-1966). He was Assistant Professor (1966- ), Associate Professor (1968- ), Professor (1972- ) and Emeritus Professor (2003- ) at the University of Michigan, USA. Research Interest: Dr. Tomozawa found that the Schwarzschild metric does not fit the data of time delay experiment in the field of general relativity. He has introduced a physical metric which fits the data. It was constructed with the constraint that the speed of light on the spherical direction is unchanged from that in vacuum. This modification changes the way we understand the nature of gravity drastically. In particular, the nature of compact objects, neutron stars and black holes, is very different from that described by the Schwarzschild metric. It also explains the dark energy, supernova explosion and high energy cosmic ray emission from AGN (Active Galactic Nuclei), massive black holes.
