An origin of the Universe determined by quantum physics and relativistic gravity
msra(2001)
摘要
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.
