Discussion: Time-Symmetric Quantum Counterfactuals
Time symmetry counterfactuals probability
2008/4/11
There is a trend to consider counterfactuals as invariably
time-asymmetric. Recently, this trend manifested itself in the
controversy about validity of counterfactual application of a
time-symmetri...

Gö del Symmetry General Relativity Time
2008/4/11
Two symmetry arguments are discussed, each purporting to show that there is no more room in general relativistic cosmology than in Minkowski spacetime for a preferred division of spacetime into instan...
Comments on Sklar's ``Barbour's Relationist Metric of Time''
Relationalism Relationism Substantivalism Barbour
2008/4/10
Julian Barbour's approach to dynamics is reviewed. With a particular focus on questions of explanation and confirmation, the approach is contrasted with standard formulations of dynamics. This paper e...
Comment on Fritz Rohrlich's "Causality and the Arrow of Classical Time".
Arrow of time extended particles time reversal
2008/4/10
Rohrlich claims that ``the problem of the arrow of time in classical dynamics has been solved". The solution he proposes is based on the equations governing the motion of extended particles. Rohrlich ...
``Branching space-time'' is a simple blend of relativity
and indeterminism. Postulates and definitions
rigorously describe the ``causal order'' relation
between possible point events. The key postu...
Absolute Becoming, Relational Becoming, and the Arrow of Time
Time Spacetime Physics Becoming Minkowski spacetime
2008/4/10
My first and main claim is that physics cannot provide empirical evidence for the objectivity (mind-independence) of absolute becoming, for the simple reason that it must presuppose it, at least to th...
3D/4D Equivalence, the Twins Paradox, and Absolute Time
three-dimensional four-dimensional physical objects
2008/4/9
The thesis of 3D/4D equivalence states that every three-dimensional description of the world is translatable without remainder into a four-dimensional description, and vice versa. In representing an o...
"On the Time Reversal Invariance of Classical Electromagnetic Theory"
time reversal invariance electromagnetic theory
2008/4/9
David Albert claims that classical electromagnetic theory is not time reversal invariant. He acknowledges that all physics books say that it is, but claims they are ``simply wrong" because they rely ...
“Time Travel” in Godel Spacetime: Why It Doesn’t Pay to Work Out All the Kinks
Time Travel Godel Spacetime
2008/4/9
Here we provide a proof that there exist closed timelike curves in Gödel spacetime with total acceleration less than 2π(9 + 6√3)^1/2. This answers a question posed by David Malament.
This paper considers the possibility that nonrelativistic quantum mechanics tells us that Nature cares about time reversal. In a classical world we have a fundamentally reversible world that appears i...

Subjective Perception of Time and a Progressive Present Moment: The Neurobiological Key to Unlocking Consciousness
Time present moment consciousness nonconscious
2008/3/31
The conclusion of physics, within both a historical and more recent context, that an objectively progressive time and present moment are derivative notions without actual physical foundation in nature...

2008/3/31
Aristotle begins his famous discussion of time in Book Δ of The Physics by asking whether time belongs to “the things that exist.” In this paper I argue that Aristotle’s apparently ambiguous answer to...
