A Critical Look at the Standard Cosmological Picture
cosmology relativity time simultaneity
2016/6/13
The discovery that the Universe is accelerating in its expansion has brought the basic concept of cosmic expansion into question. An analysis of the evolution of this concept suggests that the paradig...
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...
Multiple Uncertainties in Time-Variant Cosmological Particle Data
Visualization Applications Cosmology Parallel Coordinates Uncertainty Visualization
2015/7/29
Though the mediums for visualization are limited, the potential dimensions of a dataset are not. In many areas of scientific study, understanding the correlations between those dimensions and their un...
The purpose of this paper is to propose an extension to Lee Smolin's hypothesis that our own universe belongs to a population of universes which have evolved by natural selection. Smolin's hypothesis ...
We ordinarily assume that we have reliable knowledge of our immediate surroundings, so much so that almost all the time we entrust our lives to the truth of what we take ourselves to know, without a m...
Spacetime Substantivalism and Einstein's Cosmological Constant
cosmological constant substantivalism
2008/4/21
I offer a novel argument for spacetime substantivalism: we should take the spacetime of general relativity to be a substance because of its active role in gravitational causation. As a clear example o...
The Quantum Vacuum and the Cosmological Constant Problem
Quantum Field Theory Vacuum Cosmological Constant
2008/4/21
The cosmological constant problem arises at the
intersection between general relativity and quantum field theory, and is regarded as a fundamental problem in modern physics. In this paper we describe...
Why the Big Bang Singularity does not Help the Kalam Cosmological Argument for Theism
creation Kalam cosmological argument
2008/4/15
The Big Bang singularity provides little or no evidence for creation in the finite past and hence for theism. Whether one dismisses singularities or takes them seriously, physics licenses no first mom...
Mathematical physicist Lee Smolin has proposed a theory of Cosmological natural selection which, he argues, explains the existence of our life-supporting universe, and which, he claims, is superior to...
