Symposium »Concepts of Probability in the Sciences« Mitschnitt einer Veranstaltung des Erwin Schrödinger International Institute for Mathematics and Physics (ESI) am Dienstag, dem 30. Oktober 2018 im Boltzmann-Hörsaal des ESI Teil 12. Erik Curiel: "What is generic and what is special about the Universe?" Kamera: Matthias Dellago Schnitt: Daniel Winkler Erik Curiel ist Professor an der Fakultät für Philosophie, Wissenschaftstheorie und Religionswissenschaft der Ludwig-Maximilians-Universität München. Abstract: Some of the deepest questions in cosmology concern what features of our universe are generic and what are special. Was the highly homogeneous state of the very early universe special in some sense (i.e., unlikely, and so seemingly requiring explanation)? Do spacetimes such as ours generically possess singularities (i.e., are singularities highly probable)? To attempt to formulate such questions precisely and then address them requires probabilistic concepts and reasoning. Because of the peculiar and complex nature of the candidates to serve as probability spaces involved, standard forms of probabilistic concepts and reasoning do not apply.I discuss the problems such questions pose, and consider some possibilities for addressing them. I conclude by discussing the consequences of those problems for how we should assess the strength of standard forms of argument in sciences such as cosmology that would attempt to reason probabilistically about unique and large entities such as the universe as a whole.
