Problem of Time Quantum Gravity Symmetry
2016/6/13
On one popular view, the general covariance of gravity implies that change is relational in a strong sense, such that all it is for a physical degree of freedom to change is for it to vary with regard...
A Relic of a Bygone Age?Causation,Time Symmetry and the Directionality Argument
Causation direction of time time asymmetry time symmetry time reversal
2016/6/13
Bertrand Russell famously argued that causation is not part of the fundamental physical description of the world, describing the notion of cause as "a relic of a bygone age." This paper assesses one o...
Response to Pashby:Time operators and POVM observables in quantum mechanics
parameter time time operators time observables PVM POVM
2016/6/13
I argue against a general time observable in quantum mechanics except for quantum gravity theory. Then I argue in support of case specific arrival time and dwell time observables with a cautionary not...
The GRW flash theory:a relativistic quantum ontology of matter in space-time?
Bell’s theorem Bohmian mechanics collapse of the wave-function dispositionalism GRW flash GRW mass density Humeanism Lorentz-invariance primitive ontology propensities relativistic collapse theory
2016/6/13
John Bell proposed an ontology for the GRW modification of quantum mechanics in terms of flashes occurring at space-time points. The paper spells out the motivation for this ontology, enquires into th...
The Indivisible Now:why time must be discrete
Discrete time non-reductionism quantum mechanics quantum entanglement
2016/6/12
Discrete time has, rightly, not generally been taken very seriously with the standard conceptual framework for understanding reality. I say ‘rightly’ only because when fully understood, discrete time ...
Time in the theory of relativity:on natural clocks,proper time,the clock hypothesis,and all that
relativity Einstein natural clock atomic clock proper time clock hyothesis
2016/6/12
When addressing the notion of proper time in the theory of relativity, it is usually taken for granted that the time read by an accelerated clock is given by the Minkowski proper time. However, there ...
The back cover text of this excellent monograph closes with a b old remark on its metho dology:“[T]he assumption that the fundamental laws of physics are simple in terms of the fundamental physical pr...
Absolute, true and mathematical time in Newton’s Principia
Newton absolute time absolute motion true time mathematical time
2016/6/12
I discuss the three distinctions “absolute and relative”, “true and apparent”, and “mathematical and common”, for the specific case of time in Newton’s Principia. I argue that all three distinctions a...
I provide a self-contained introduction to the problem of the arrow of time in physics, concentrating on the irreversibility of dynamical processes as described in statistical mechanics.
The fundamental arrow of time in classical cosmology
Time Asymmetries Cosmology Cosmological Time Arrow
2016/5/31
The aim of this paper is to show that a new understanding of fundamentality (section 2), can be applied successfully in classical cosmology and is able to improve a fundamental understanding of cosmol...
Newton’s Philosophy of Time
Newton Descartes Huygens mathematical time absolute time true time
2016/5/31
In this paper I explain what Newton means with the phrase “absolute, true, and mathematical time” (Principia, Scholium to the definitions) in order to discuss some of the philosophic issues that it gi...
Genidentity and Topology of Time:Kurt Lewin and Hans Reichenbach
Genidentity topology of time causal theory of time relativized a priori Kurt Lewin Hans Reichenbach
2016/5/31
In the early 1920s, Hans Reichenbach and Kurt Lewin presented two topological accounts of time that appear to be interrelated in more than one respect. Despite their different approaches, their underl...
What can we Learn about the Ontology of Space and Time from the Theory of Relativity
space time relativity
2016/5/30
This chapter presents an opinionated assessment of what we can learn about the ontology of space and time from the special and general theories of relativity. It uses the requirements of novelty, mode...
Time in quantum gravity
quantum gravity problem of time quantum general relativity string theory noncommutative spacetime metaphysics of space metaphysics of time causation
2016/5/30
Quantum gravity--the marriage of quantum physics with general relativity--is bound to contain deep and important lessons for the nature of physical time. Some of these lessons shall be canvassed here,...
Time and Fitness in Evolutionary Transitions in Individuality
Evolutionary transitions in individuality Okasha,Michod,MLS1 MLS2 species selection
2016/5/27
It is striking that the concept of fitness although fundamental in evolutionary theory, still remains ambiguous. I argue here that time, although usually neglected, is an important parameter in regard...
