To do so, we propose a classical-quantum duality. We also generalize the Schordinger equation to the spacetime and obtain a relativistic wave equation. This will lead a generalization of Einstein's formula $E=m_0c^2$ in the spacetime. In general, we have $E=m_0c^2 + \frac{\hbar^2}{12m_0}R$ in a spacetime.15 pagesGeneral Relativity and Quantum CosmologyAn Equation of Motion with Quantum Effect in Spacetimetext
