Title: Before Time: Loop Quantum Cosmology and Philosophy of Science
Abstract: Quantum Cosmology seeks to explain what happened at the Big Bang -- or even before. But how can initial conditions be both necessary for physical explanations (as an explanans), and yet have to be explained themselves in Big Bang cosmology (as explananda)? And what is the relationship between boundary conditions, constants of nature, and physical laws -- are they all mere initial conditions? The talk shall address these questions on a conceptual level and compare the approach of Loop Quantum Cosmology (LQC) with other quantum cosmological proposals. The advantage of LQC shall be shown from a Philosophy of Science perspective, and with regard to a possible solution of the question whether our universe did or did not have a beginning. Some problems of most recent results in LQC are also discussed.
