Quantum cosmology and the arrow of time
Although most fundamental laws are invariant under time reversal, experience exhibits the presence of irreversible phenomena - the arrows of time. Their origin lies in cosmology, and I argue that only quantum cosmology can provide the appropriate formal framework. After briefly reviewing the formalism, I discuss how a simple and natural boundary condition can lead to the observed arrows of time. This yields at the same time interesting consequences for black holes.
