George Ellis - On the philosophy of cosmology

Vendredi 1er juin 11:00-12:00

This talk will summarise what we presently know and don’t know about the physical universe, and consider limits to what we probably ever will know due to the unique nature of the universe and existence of observational horizons. It will discuss problems with our current model such as the unknown nature of dark energy and the mechanism of inflation, and the consequent importance of investigating alternative models of the universe and effects such as the backreaction of structure on its evolution. Finally it will consider whether multiverse proposals should be considered as scientific or philosophical proposals.
