Group field theories: decoupling spacetime emergence from the ontology of non-spatiotemporal entities
摘要
With the present paper I maintain that the group field theory (GFT) approach to quantum gravity can help us clarify and distinguish the problems of spacetime emergence from the questions about the nature of the quanta of space. I will show that the use of approximation methods can suggest a form of indifference between scales (or phases) and that such an indifference allows us to black-box questions about the nature of the ontology of the fundamental levels of the theory.
