The Multiverse: a Philosophical Introduction
Jeremy Butterfield
This book is a philosopher's introduction to the idea that our universe is just one of many universes. I present and assess three versions of the idea: one version from philosophy,…
A frame-bundle formulation of quantum reference frames: from superposition of perspectives to superposition of geometries
Daniel A. Turolla Vanzella, Jeremy Butterfield
We provide a possible fully geometric formulation of the core idea of quantum reference frames (QRFs) as it has been applied in the context of gravity, freeing its definition from…
Identification is Pointless: Quantum Coordinates, Localisation of Events, and the Quantum Hole Argument
Viktoria Kabel, Anne-Catherine de la Hamette, Luca Apadula +4
The study of quantum reference frames (QRFs) is motivated by the idea of taking into account the quantum properties of the reference frames used, explicitly or implicitly, in our d…
En Route to Reduction: Lorentzian Manifolds and Causal Sets
Jeremy Butterfield
I present aspects of causal set theory (a research programme in quantum gravity) as being en route to achieving a reduction of Lorentzian geometry to causal sets. I take reduction…
On the Emergence of Time in Quantum Gravity
C. J. Isham, J. Butterfield
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…
