Description (de)
Public Lecture im Rahmen des 9th Vienna Central European Seminar on Particle Physics and Quantum Field Theory Mitschnitt einer Veranstaltung am Freitag, dem 30. November 2012 im Lise-Meitner-Hörsaal der Fakultät für Physik Begrüßung und einleitende Worte: Helmuth Hüffel (Fakultät für Physik) und Piotr Chruściel (Fakultät für Physik) Abstract: The theory of conformal cyclic cosmology (CCC) takes what we currently regard as the entire history of the Universe, from its Big-Bang origin (but without any "inflationary phase") to its final exponential expansion, to be just one aeon of a continual succession of such aeons. The big bang of each aeon is assumed to be an infinitely scaled down continuation of the exponentially expanding remote future of the aeon that preceded it. The existence of Einstein’s tiny positive constant Λ (i.e. dark energy) is essential to CCC's consistency, as is some primordial scalar material (taken to be dark matter). Colliding supermassive black holes in the aeon previous to ours would have important observational implications for CCC, detectable within the ubiquitous cosmic microwave background. Sir Roger Penrose ist ein britischer Physiker und Mathematiker, der vor allem durch seine Beiträge zur Kosmologie und die nach ihm benannten nichtperiodischen Parkettierungen der Ebene bekannt geworden ist.
