Spacetime Quietism in Quantum Gravity
- Philosophy, Physics
- 2022
The existence and fundamentality of spacetime has been questioned in quantum gravity where spacetime is frequently described as emerging from a more fundamental nonspatiotemporal ontology. This is…
Emergence of Spacetime from Structural Interpretations
- PhysicsJournal of the Japan Association for Philosophy of Science
- 2020
In recent discussions as to emergence of spacetime, spacetime is said to be not fundamental in quantum regions, which we must apply quantum gravity’s theory to and to be derived from fundamental…
Thinking about Spacetime
- PhilosophyPhilosophy Beyond Spacetime
- 2021
Several different quantum gravity research programmes suggest, for various reasons, that spacetime is not part of the fundamental ontology of physics. This gives rise to the problem of empirical…

Research in quantum gravity strongly suggests that our world in not fundamentally spatiotemporal, but that spacetime may only emerge in some sense from a non-spatiotemporal structure, as this paper…

Spacetime emergence in quantum gravity: functionalism and the hard problem
- PhilosophySynthese
- 2019
Spacetime functionalism is the view that spacetime is a functional structure implemented by a more fundamental ontology. Lam and Wüthrich have recently argued that spacetime functionalism helps to…
Spacetime Emergence: Collapsing the Distinction Between Content and Context?
- Philosophy, Physics
- 2021
Several approaches to developing a theory of quantum gravity suggest that spacetime—as described by general relativity—is not fundamental. Instead, spacetime is supposed to be explained by reference…
When the actual world is not even possible
- Philosophy, Art

Approaches to quantum gravity often involve the disappearance of space and time at the fundamental level. The metaphysical consequences of this disappearance are profound, as is illustrated with…

To Quantize or Not to Quantize: Fact and Folklore in Quantum Gravity
- Physics
- 2005
Does the need to find a quantum theory of gravity imply that the gravitational field must be quantized? Physicists working in quantum gravity routinely assume an affirmative answer, often without…
Generic predictions of quantum theories of gravity
- Physics
- 2009
I discuss generic consequences (sometimes called “soft predictions”) of a class of background independent quantum theories of spacetime called causal spin network theories. These are theories whose…
Reflections on the Fate of Spacetime
- Physics
- 1996
Our basic ideas about physics went through several upheavals early this century. Quantum mechanics taught us that the classical notions of the position and velocity of a particle were only…
Completeness, supervenience and ontology
- Philosophy
- 2007
In 1935, Einstein, Podolsky and Rosen raised the issue of the completeness of the quantum description of a physical system. What they had in mind is whether or not the quantum description is…
Modern Canonical Quantum General Relativity
- Physics
- 2007
This is an introduction to the by now fifteen years old research field of canonical quantum general relativity, sometimes called "loop quantum gravity". The term "modern" in the title refers to the…
Approaches to Quantum Gravity: Does locality fail at intermediate length scales?
- Physics
- 2009
If quantum gravity implies a fundamental spatiotemporal discreteness, and if its ``laws of motion'' are compatible with the Lorentz transformations, then physics cannot remain local. One might expect…
On the Emergence of Time in Quantum Gravity
- Philosophy
- 1999
We discuss from a philosophical perspective the way in which the normal concept of time might be said to `emerge' in a quantum theory of gravity. After an introduction, we briefly discuss the notion…
