Connections between quantum theory and cosmology:: An unconventional view

Quantum theory is the most fundamental theory which is known today. There is not any part in nature which suggests its failure. For an introduction to the philosophy of quantum theory see [5]. For many cases in nature classical physics is sufficiently good. Only the,existence and stability of a ground state is beyond any reach of classical concepts. From the mathematics of quantum theory it follows by its first principles that it is a theory for the "wholeness' - irrespective of the point of extensions. At present we can see that quantum theory has its most fundamental aspect in the field of information. Quantum computing gets a rising importance, but also at the interconnection of quantum theory and general relativity, in case of the Bekenstein-Hawking-Radiation, the informational aspect is central.
