Review of Time and the Metaphysics of Relativity
the Metaphysics of Relativity Review of Time
2008/4/22
In his recent book Time and the Metaphysics of Relativity, William Lane Craig uses the concept of time to try to reconstruct strong conceptual links between theology, metaphysics and physics, three ve...
Some Thoughts on Relativity and the Flow of Time: Einstein's Equations given Absolute Simultaneity
Einstein Relativity
2008/4/21
The A-theory of time has intuitive and metaphysical appeal, but suffers from tension, if not inconsistency, with the special and general theories of relativity (STR and GTR). The A-theory requires a n...
Special relativity is most naturally formulated as a theory of spacetime geometry, but within the spacetime framework probability appears to be a purely epistemic notion. It is possible that progress ...
Space-time relationism in Newtonian and relativistic physics
space time relativity relationism
2008/4/21
I argue that there is a natural relationist interpretation of Newtonian and relativistic non-quantum physics. Although relationist, this interpretation does not fall prey to the traditional objections...
Special Relativity, Time, Probabilism, and Ultimate Reality
Special relativity time spacetime quantum theory
2008/4/21
McTaggart distinguished two conceptions of time: the A-series, according to which events are either past, present or future; and the B-series, according to which events are merely earlier or later tha...
General relativity is commonly thought to imply the existence of a unique metric structure for space-time. A simple example is presented of a general relativistic theory with ambiguous metric structur...
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, ...
