We discuss the evolution of the Universe from what might be called its quantum origin. We apply the uncertainty principle to the origin of the Universe with characteristic time scale equal to the Planck time to obtain its initial temperature and density. We establish that the subsequent evolution obeying the Einstein equation gives the present temperature of the microwave background close to the observed value. The same origin allows the possibility that the Universe started with exactly the critical density, Omega =1, and remained at the critical density during evolution. Many other important features of the observed Universe, including homogeneity and isotropy, Hubble's constant at origin, its minimum age, present density etc. are all predictions of our theory. We discuss also the testability of our theory.
