Spacetime: Fundamental or Emergent?

Tagung/Kongress/Symposium
Inhalt:

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.
