Philosophy of Physics

  title={Philosophy of Physics},
  author={Tim Maudlin},
We prove that under some technical assumptions on a general, non-classical probability space, the probability space is extendible into a larger probability space that is common cause closed in the sense of containing a common cause of every correlation between elements in the space. It is argued that the philosophical significance of this common cause completability result is that it allows the defence of the Common Cause principle against certain attempts of falsification. Some open problems…

Matter in Motion: The Scientific Image of the World
This chapter elaborates on what the ontological commitments of science are and what they are not. It focuses on the fundamental and universal theories of physics from Newtonian mechanics to today’s
Husserl, the mathematization of nature, and the informational reconstruction of quantum theory
As is well known, the late Husserl warned against the dangers of reifying and objectifying the mathematical models that operate at the heart of our physical theories. Although Husserl’s worries were
Violations of locality and free choice are equivalent resources in Bell experiments
This work investigates the extent to which a given assumption needs to be relaxed for the other to hold at all costs, based on the observation that a violation need not occur on every experimental trial, even when describing correlations violating Bell inequalities.
Spacetime functionalism from a realist perspective
In prior work, we have argued that spacetime functionalism provides tools for clarifying the conceptual difficulties specifically linked to the emergence of spacetime in certain approaches to quantum

The violation of Bell’s inequality has shown that quantum theory and relativity are in tension : reality is nonlocal. Nonetheless, many have argued that GRW-type theories are to be preferred to


The Principle of the Common Cause
The common cause principle says that every correlation is either due to a direct causal effect linking the correlated entities or is brought about by a third factor, a so-called common cause. The
General Covariance and the "Problem of Time" in a Discrete Cosmology
Identifying an appropriate set of ``observables'' is a nontrivial task for most approaches to quantum gravity. We describe how it may be accomplished in the context of a recently proposed family of
What Becomes of a Causal Set?
It is shown that a novel and exotic notion of becoming is compatible with causal sets, and while not answering to the typical A-theoretic demands, is global and objective.

Abstract I explore physics implications of the External Reality Hypothesis (ERH) that there exists an external physical reality completely independent of us humans. I argue that with a sufficiently

The questions about singularities that remain to be answered are discussed. It is shown, without any assumption about causality, that there are fully general solutions which evolve from a

For the generalizations of thermodynamics to obtain, it appears that a very ‘special’ initial condition of the universe is required. Is this initial condition itself in need of explanation? I argue
Causal sets as discrete spacetime
Causal set theory is an approach to the problem of quantum gravity in which spacetime is fundamentally discrete and in which causality is a primary concept. The concrete kinematics of the approach
Bell’s Theorem, Realism, and Locality
According to a recent paper by Tim Maudlin, Bell’s theorem has nothing to tell us about realism or the descriptive completeness of quantum mechanics. What it shows is that quantum mechanics is
Classical sequential growth dynamics for causal sets
Starting from certain causality conditions and a discrete form of general covariance, we derive a very general family of classically stochastic, sequential growth dynamics for causal sets. The
