Response to `Local and global definitions of time:Cosmology and quantum theory'
Local global definitions time Cosmology quantum theory
2016/6/15
I will discuss the notion of time and spatial finiteness from the perspective of observational cosmology. Our observed universe is well described at early times by small fluctuations in the spatial gr...
Local and global definitions of time:Cosmology and quantum theory
Cosmology relational time spatial extent time
2016/6/15
I will give a broad overview of what has become the standard paradigm in cosmology. I will describe the relational (\`{a} la Leibnitz) notion of time that is often used in cosmological calculations an...
Does cosmological expansion affect local physics?
Cosmology General Relativity Black Holes
2016/6/13
In this contribution I wish to address the question whether, and how, the global cosmological expansion influences local physics, like particle orbits and black hole geometries. Regarding the former I...
Non-local common cause explanations for EPR
Bell’s theorem Bohmian mechanics EPR experiment GRW mass density theory local causality non-local causes
2016/6/13
The paper argues that a causal explanation of the correlated outcomes of EPR-type experiments is desirable and possible. It shows how Bohmian mechanics and the GRW mass density theory offer such an ex...
Local, General and Universal Prediction Strategies: A Game-Theoretical Approach to the Problem of Induction
Problem of Induction Meta-Induction Prediction Method
2008/4/22
In this paper I present a game-theoretical approach to the problem of induction. I investigate the comparative success of prediction methods by mathematical analysis and computer programming. Hume's p...
Passage of Time in a Planck Scale Rooted Local Inertial Structure
Flow of time Temporal Transience
2008/4/22
It is argued that the `problem of time' in quantum gravity necessitates a refinement of thelocal inertial structure of the world, demanding a replacement of the usual Minkowski lineelement by a 4+2n d...
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...
Matrix models as non-local hidden variables theories
hidden variables theory quantum gravity
2008/4/15
It is shown that the matrix models which give non-perturbative definitions of string and
M theory may be interpreted as non-local hidden variables theories in which the quantum
observables are the e...
This paper is an analysis of the geometrical interpretation of local gauge symmetry for theories of the Yang-Mills type.
Disproof of Bell's Theorem by Clifford Algebra Valued Local Variables
Bell's Theorem Local Causality Local realism
2008/4/11
It is shown that Bell's theorem fails for the Clifford algebra valued local realisticvariables. This is made evident by exactly reproducing quantum mechanical expectationvalue for the EPR-Bohm type sp...
A local hidden-variable model violating Bell's inequalities
A local hidden-variable inequalities
2008/4/9
A local hidden-variable model for two spin-1/2 particles is shown to
reproduce the quantum-mechanical outcomes and expectation values,
and hence to violate Bell's inequality. Contrarily to the usual...
A recent analysis by de Barros and Suppes of experimentally realizable
GHZ correlations supports the conclusion that these correlations
cannot be explained by introducing local hidden variables. We ...
