We discuss the possibility to build and operate a time machine, a device that produces closed timelike curves (CTCs). We specify the spacetime structure needed to implement a time machine and assess a...
This paper argues that the Einstein-Minkowski space-time of special relativity provides an adequate model for classical tense logic, including rigorous definitions of tensed becoming and of the logica...
Here I develop the idea, which I have presented elsewhere, that time instants are abstract entities existing tenselessly and therefore that events and changes likewise may be said to exist tenselessly...
The reason for the arrow of time in electromagnetic radiation is explicated
Scientific cosmology is an empirical discipline whose objects of study are the large-scale properties of the universe. In this context, it is usual to call the direction of the expansion of the univer...
The Arrow of Time in Rigged Hilbert Space Quantum Mechanics
Arrow of Time Quantum Mechanics Irreversibility
2008/4/21
Arno Bohm and Ilya Prigogine's Brussels-Austin Group have been working on the quantum mechanical arrow of time and irreversibility in rigged Hilbert space quantum mechanics. A crucial notion in Bohm's...
The Dynamics of Time and Timelessness:Philosophy, Physics and Prospects for our Life
ontology physics biology consciousness
2008/4/21
We point out that physical behavior is directed by the action principle (or Hamilton principle), while biological behavior is governed
by the Bauer-principle which is directed against the action prin...
The incompleteness of extensional object languages of physics and time reversal. Part 2.
logic of physics intensional semantics for physics
2008/4/21
This continues from Part 1. It is shown how an intensional interpretation of physics object languages can be formalised, and how a syntactic compositional time reversal operator can subsequently be de...
The present moment in quantum cosmology: Challenges to the arguments for the elimination of time
cosmology relativity quantum cosmology
2008/4/21
Barbour, Hawking, Misner and others have argued
that time cannot play an essential role
in the formulation of a quantum theory of cosmology. Here we present
three challenges to their arguments, ...
The Non-Local to Local Space-time Map
Non-local frames Holographic Model of Quantum states
2008/4/21
While for point particles a local theory seems to be sufficient, when it comes to extended objects like Strings and Branes you by rights are not dealing with a specifically fully localized particle to...
The analysis of the reversibility of quantum mechanics depends upon the choice of the time reversal operator for quantum mechanical states. The orthodox choice for the time reversal operator on QM sta...
The Representation of Time and Change in Mechanics
Classical Mechanics General Relativity Symmetry Time
2008/4/21
This paper is concerned with the representation of time and change in
classical (i.e., non-quantum) physical theories. One of the main goals is to attempt to clarify the nature and scope of the so-ca...
The Thermodynamical Arrow of Time: Reinterpreting the Boltzmann-Schuetz Argument
arrow of time entropy
2008/4/21
The recent surge of interest in the
origin of the temporal asymmetry of thermodynamical systems
(including the accessible part of the universe itself) put forward
two possible explanatory approache...
The time reversal invariance of classical electromagnetic theory: Albert versus Malament.
time reversal invariance electromagnetic theory
2008/4/21
David Albert has recently argued that classical electromagnetic theory (EM) is not time reversal invariant (non-TRI), while David Malament rejects this argument and maintains the orthodox result, that...
The singular nature of space-time
General relativity space-time singularities space-time points
2008/4/21
We consider to what extent the fundamental question of space-time singularities is relevant for the philosophical debate about the nature of space-time. After reviewing some basic aspects of the space...
