Topic

Spacetime or spatiotemporal relations have traditionally been considered as perfect candidates for fundamental entities or structures of reality. However, in modern physics and philosophy this general agreement has been challenged by, for example, physical theories that try to recover spacetime as an emergent structure resulting in the current debate on the (non-)fundamentality of spacetime. With respect to this debate, our workshop attempts to explore three central aspects: First, what kind of entity is spacetime? Is it essentially a geometrical entity, as the received view has it, or just a physical field that can be described by geometrical means? Is that field grounding other physical fields, or is it rather one among many? Second, this naturally evokes the question of what is involved in claims of fundamentality of physical entities, and thus is connected to a current debate in the metaphysics of science. We suggest that the issue of fundamentality or emergence is where the general metaphysical status of scientific entities is reflected within physics. Third, the foregoing topics merge in the concrete question of what different approaches to quantum gravity, like loop quantum gravity, the spin-2 approach, or string theory, may reveal about the status of spacetime. Is spacetime an emergent entity as most approaches seem to suggest? If so, which concept of emergence will apply? We suggest that these questions indicate how closely metaphysical issues are entangled with the current development of physics.

Venue
Universitätsclub Bonn, Konviktstr. 9, 53113 Bonn

Directions
From Cologne/Bonn Airport to Bonn Central Station:
Take the bus (SB 60) from the airport terminal to Bonn Central Station (“Bonn Hauptbahnhof”). It takes approximately 30 minutes.

From Düsseldorf Airport to Bonn Central Station:
Either you take the train RE 5 to Koblenz via Bonn Central Station or you get to Düsseldorf Central Station (“Düsseldorf Hauptbahnhof”) first and then take the IC to Offenburg via Bonn Central Station. Both takes about an hour.

From Frankfurt Airport to Bonn Central Station:
Take the IC directing to Cologne Central Station (“Köln Hauptbahnhof”) via Bonn Central Station (less than two hours ride). It is also possible to take the ICE directing to Cologne Central Station which you exit at “Siegburg/Bonn”. From there you get on the tram 66 (STR 66) from Siegburg Station (“Siegburg Bahnhof”) to Bonn Central Station (approximately one hour in total).

From Bonn Central Station to Uni Club:
For Uni Club, exit Bonn Central Station via “Poststraße”, then turn right to “Am Hauptbahnhof”, leave behind the bus station and make your way to “Kaiserplatz” (via “Maximilianstraße”) which you cross turn left into “Regina-Pacis-Weg”. Follow “Regina-Pacis-Weg” to Bonn University's main building (left-hand side) and “Hofgarten” (right-hand side). Shortly after, you cross “Adenauer Alle” and immediatly turn left through “Koblenzer Tor”. Then turn right into “Konviktstraße”. After about 200 meters you will see the University Club's main entrance on the left-hand side. It takes about 10 minutes.
