## Research Overview

In the 1970s it became known that, of the four interactions that act upon elementary particles, the electromagnetic interaction, the weak interaction and the strong interaction can be described by means of gauge theory; this has been well verified by experiments. In 2002 it was confirmed that the phenomenon known as violation of CP symmetry can be explained in detail using the six-quark theory proposed jointly by
Makoto Kobayashi and myself. The remaining issue would seem to be supersymmetric particles, and it is probably just a matter of time until they are confirmed by experiments.

Another issue that remains is quantum gravity. Promising candidate theories for this problem such as string theory have been advanced, and particle physicists all over the world are competing to complete the theory. Recall that the Newtonian mechanics, which could not be applied to the microworld and objects moving at nearly the speed of light, was eventually replaced by new theory that satisfy the requirements of quantum mechanics and relativity theory. Similarly to this, I consider quantum gravity to be a problem of space-time in the hyper microworld, and I hope to reconstruct the concept of space-time to satisfy the requirements of this world. I don't think this problem is a simple one, but as I have received a certain amount of public recognition of my work
thus far, I think it might be a good idea to try an approach that differs somewhat from the current fashion.
