Professor Tomozawa's studies include theoretical and experimental work on the solar neutrino problem (the depletion of solar neutrino flux). His work on the enhancement of neutrino cross-sections by magnetoplasma properties attempts to explain observed anticorrelation of the solar neutrino flux and solar activity in recent experiments. Professor Tomozawa is also exploring the possibility of an efficient neutrino detector and a control of radioactivity.More recently, Professor Tomozawa found that the Schwarzschild metric does not fit the data of time delay experiment in the field of general relativity. He 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, it explains the dark energy.
