Quantum Cosmology and the Arrow of Time
نویسنده
چکیده
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. Contribution to the Proceedings of the conference DICE2004, Piombino, Italy, September 2004; to appear in Brazilian Journal of Physics.

We elaborate on some recent results on a solution of the Hilbert-space problem in minisuperspace quantum cosmology and discuss the consequences of making the (geometry of the) Hilbert space of ordinary nonrelativistic quantum systems time-dependent. The latter reveals a remarkable similarity between Quantum Mechanics and General Relativity.
متن کاملQuantum Cosmology
We comment on two issues in quantum cosmology, in the context of the Wheeler–De Witt equation and wave function of the Universe: (i) arrow of time and interpretation of the wave function in the classically allowed regions; (ii) stability of an approximation of the Born–Oppenheimer type in classically forbidden regions of the scale factor.

Fisher's arrow of time is introduced in quantum cosmology. Assuming that the evolution of the universe in phase space starts from an initial squeezed cosmological state towards a final thermal one, a Fokker-Planck equation for the time-dependent, cosmological Q phase space probability distribution can be written down. Next, using some recent results in the literature, we derive an information a...
متن کاملVariable Speed of Light Cosmology: An Alternative to Inflation
It is generally believed that inflationary cosmology explains the isotropy, large scale homogeneity and flatness as well as predicting the deviations from homogeneity of our universe. We show that this is not the only cosmology which can explain successfully these features of the universe. We review a model in which local Lorentz invariance is spontaneously broken in the very early universe, an...
متن کاملTime Symmetry and Asymmetry in Quantum Mechanics and Quantum Cosmology
All of these time asymmetries could arise from time-symmetric dynamical laws solved with time-asymmetric boundary conditions. The thermodynamic arrow of time, for example, is implied by an initial condition in which the progenitors of today’s approximately isolated systems were all far from equilibrium at an initial time. The CP arrow of time could arise as a spontaneously broken symmetry of th...
