On Friday, 21 May, Baptiste Le Bihan (University of Geneva) will give a
talk entitled “Spacetime, Quantum Gravity, and Mereology” (abstract below).

The meeting will take place online on Zoom (17:00-19:00 CEST). If you have

The Colloquium is organized by the Philosophy of Physics Group at the
International Center for Formal Ontology (Faculty of Administration and
Social Sciences, Warsaw University of Technology).

ABSTRACT
According to a number of approaches in theoretical physics spacetime does
not exist fundamentally. Rather, spacetime exists by depending on another,
more fundamental, non-spatiotemporal structure. A prevalent opinion in the
literature is that this dependence should not be analysed in terms of
composition. We should not say, that is, that spacetime depends on an
ontology of non-spatiotemporal entities in virtue of having them as parts.
But is that really right? On the contrary, we argue that a mereological
approach to dependent spacetime is not only viable, but promises to enhance
our understanding of the physical situation. (Based on a joint work with
Sam Baron)
