Philosophical Questions

This introductory chapter provides an overview of philosophy of physics, which is an interdisciplinary field sitting between physics proper, mainstream philosophy, and the general philosophy of science, and communicating ideas and insights between them. Philosophy of physics is mostly concerned not with physics as a whole but with particular areas within it. Given a field in physics, one can consider the conceptual—that is, philosophical—questions that arise in that field, and the problems in each sub-field are distinctive. The chapter briefly discusses many of these, including some in cutting-edge areas of physics like quantum cosmology, black holes, and string theory. But it notes that the bulk of work in philosophy of physics is concerned with three areas where the physics is reasonably well established: the philosophy of spacetime; the philosophy of statistical mechanics; and the philosophy of quantum mechanics.

Philosophical Importance

We present a brief history of decoherence, from its roots in the foundations of classical statistical mechanics, to the current spin bath models in condensed matter physics. We then analyse the philosophical importance of decoherence in three different foundational problems, and find that its role in their solutions is less than that commonly believed. What makes decoherence more philosophically interesting, we argue, are the methodological issues it draws attention to, and the question of the universality of quantum mechanics.

Definitive Form

This introductory chapter provides a brief summary of the discussions in the succeeding chapters. Here, the new quantum mechanics has in recent years achieved in its essential parts what is presumably a definitive form: the so-called “transformation theory.” Therefore the principal emphasis shall be placed on the general and fundamental questions which have arisen in connection with this theory. In particular, the difficult problems of interpretation, many of which are even now not fully resolved, will be investigated in detail. In this connection, the relation of quantum mechanics to statistics and to the classical statistical mechanics is of special importance.

Philosophical Questions

This is the second volume in Oxford Studies in Experimental Philosophy, a series with the aim of providing a venue for publishing work in this emerging field. Experimental philosophy is a new movement that seeks to use empirical techniques to illuminate some of the oldest issues in philosophy. It is an interdisciplinary field at the intersection of philosophy, psychology, and related disciplines, such as linguistics and sociology. Although the movement is only a few years old, it has already sparked an explosion of new research, challenging a number of cherished assumptions in both philosophy and the cognitive sciences. This volume includes both theoretical and experimental chapters as well as chapters that cross traditional disciplinary boundaries. It is divided into three parts that explore epistemology, moral and political philosophy, and metaphysics and mind, showcasing the diversity of work that has arisen as traditionally philosophical questions have met the tools of social science.

The Impact

Bootstrapped Newtonian gravity was developed with the purpose of estimating the impact of quantum physics in the nonlinear regime of the gravitational interaction, akin to corpuscular models of black holes and inflation. In this work, we set the ground for extending the bootstrapped Newtonian picture to cosmological spaces. We further discuss how such models of quantum cosmology can lead to a natural solution to the cosmological constant problem.

If string theory is correct, then our observable universe may be a three-dimensional "brane" embedded in a higher-dimensional spacetime. This theoretical scenario should be tested via the state-of-the-art in gravitational experiments — the current and upcoming gravity-wave detectors. Indeed, the existence of extra dimensions leads to oscillations that leave a spectroscopic signature in the gravity-wave signal from black holes. The detectors that have been designed to confirm Einstein's prediction of gravity waves, can in principle also provide tests and constraints on string theory.
