摘要：
We present a method, which we shall call the probablistic evolutionary process, based oil the probabilistic nature of quantum theory to offer a possible solution to the problem of time in quantum cosmology. It offers ail alternative for perceiving an a-row of time which is compatible with the thermodynamical arrow of time and makes a new interpretation of the FRW universe in vacua which is consistent with creation of a de Sitter space-time from nothing. This is a completely quantum result with no correspondence in classical cosmology. (C) 2009 Published by Elsevier B.V.
