Absolute Simultaneity and the Principle of Stable Causality
Presentism special relativity philosophy of time relativity of simultaneity
2016/5/31
Einsteins relativity of simultaneity had a deep impact on the pilosophy of time. A first conclusion is that there is no such thing as absolute time.Furthermore according to relativity of simultaneity ...
Simultaneity,Convention,and Gauge Freedom
simultaneity convention special relativity gauge freedom hole argument
2016/5/31
As is well known from Einstein (1905) the choice of a criterion for distant simultaneity is equivalent to stipulating one-way speeds for the transit of light. It is shown that any choice of non-standa...
The relativity of simultaneity and presentism
presentism eternalism theory of relativity relativity of simultaneity Einstein
2016/5/27
According to conventional wisdom, presentism is at odds with the theory of relativity. This is supposed to be shown quite simply just by considering the relativity of simultaneity. In this paper I wil...
On various senses of “conventional” and their interrelation in the philosophy of physics: simultaneity as a case study
conventionality simultaneity relativity theory
2009/9/16
My aim in this note is to disambiguate various senses of ‘conventional’ that in the philosophy of physics have been frequently conflated. As a case study, I will refer to the well-known issue of the c...
Reichenbach and the Conventionality of Distant Simultaneity in Perspective

We take another look at Reichenbach’s 1920 conversion to conventionalism, with a special eye to the background of his ‘conventionality of distant simultaneity’ thesis. We argue that elements of Reiche...

Relativity of Simultaneity and Eternalism: In Defense of Blockworld
Blockworld special relativity presentism
2008/4/22
Ever since the now infamous comments made by Hermann Minkowski in 1908 concerning the proper way to view space-time, the debate has raged as to whether or not the universe should be viewed as a four-d...
Reichenbach's Epsilon Definition of Simultaneity in Historical and Philosophical Perspective
Reichenbach simultaneity convention
2008/4/22
I examine the development of Reichenbach's ideas concerning the conventionality of simultaneity in connection with his ``epsilon''-definition of simultaneity. It does not appear that he ever considere...
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...

Is Simultaneity Conventional Despite Malament's Result?
simultaneity convention special relativity
2008/4/15
Many take Malaments result that the standard Einstein simultaniety relation is uniquely definable from the causal structure of Minkowski space-time to be tantamount to a refutation of the claim that c...
Conventionality of Simultaneity and Reality
One-way velocity of light conventionality of simultaneity spacetime dimensionality of the world
2011/9/7
An important epistemological lesson can be learned from the impossibility to determine the one-way velocity of light and the immediate implication that simultaneity is conventional. The vicious circle...

Relativity of Simultaneity
2008/4/11
It is routinely assumed that Einstein discovered the relativity of simultaneity by thinking about how clocks can be synchronized by light signals, much in accord with the analysis he gave in his 1905 ...

2008/4/11
The question whether distant simultaneity (relativizedto an inertial frame) has a factual or a conventional status in special relativity has long been disputedand remains in contention even today. At...
David Malament and the Conventionality of Simultaneity: A Reply
Grunbaum's Reply to Malament metrical simultaneity
2008/4/11
In 1977, David Malament proved the valuable technical result that the simultaneity relation of standard synchrony with respect to an inertial observer O is uniquely definable in terms of the relation ...
