Title: The Big Bang and Loop Quantum Cosmology PDF [1 MB] of the slides Audio [. wav, 35MB] Audio [. aif, 3. 7MB] of the talk of the talk Abstract: The talk deals with the recent developments in homogeneous and isotropic loop quantum cosmology on the Planck scale physics near the Big Bang. By constructing the physical Hilbert space, Dirac observables and physical semi-classical states definite and robust predictions about quantum nature of big bang can be made.
