To solve a problem wherein integration of gravity and inertia force is only a hypothesis when no experimental proof exists, although the both are integrated by considering that the gravity and inertia force are generated with incidence of an ether flow, in particular, an energy flow with an angle into a body.

A geometric situation of a diagonal energy flow is concretely discussed when a landscape in a front side is observed magnifiedly under an acceleration motion. That is, the hypothesis is progressed remarkably as a nobel principle. The present invention proves that the landscape in the front side is observed magnifiedly under the acceleration motion.
