Learning from a simulated universe: the limits of realistic modeling in astrophysics and cosmology.
Computers models and simulations Realism Cosmology
2008/4/22
As noticed recently by Winsberg (2003), how computer models and simulations get their epistemic credentials remains in need of epistemological scrutiny. My aim in this paper is to contribute to fill t...
Recent developments in cosmology indicate that every history having a nonzero probability is realized in infinitely many distinct regions of spacetime. Thus, it appears that the universe contains infi...
Self-Locating Belief in Big Worlds: Cosmology’s Missing Link to Observation
self-locating belief anthropic principle self-sampling assumption
2008/4/22
Current cosmological theories say that the world is so big that all possible observations are in fact made. But then, how can such theories be tested? What could count as negative evidence? To answer ...
Scientific cosmology is an empirical discipline whose objects of study are the large-scale properties of the universe. In this context, it is usual to call the direction of the expansion of the univer...
The aim of this paper is not only to deal with the concept of infinity, but also to develop some considerations about the epistemological status of cosmology. These problems are connected because from...
The present moment in quantum cosmology: Challenges to the arguments for the elimination of time
cosmology relativity quantum cosmology
2008/4/21
Barbour, Hawking, Misner and others have argued
that time cannot play an essential role
in the formulation of a quantum theory of cosmology. Here we present
three challenges to their arguments, ...
The purpose of this paper is to review, clarify, and critically analyse modern mathematical cosmology. The emphasis is upon the mathematical structures involved, rather than numerical computations. Th...
Time before Time - Classifications of Universes in contemporary cosmology, and how to avoid the antinomy of the beginning and eternity of the world
cosmology big bang big crunch universe
2008/4/21
Did the universe have a beginning or does it exist forever, i.e. is it eternal at least in relation to the past? This fundamental question was a main topic in ancient philosophy of nature and the Midd...
This paper follows up a debate as to the consistency of Newtonian cosmology. Whereas Malament (1995) has shown that Newtonian cosmology *is* not inconsistent, to date there has been no analysis of Nor...
Modern cosmology treats space and time, or rather space-time, as concrete particulars. The General Theory of Relativity combines the distribution of matter and energy with the curvature of space-time....

During the last three decades, there has been a growing
realization among physicists and cosmologists that the relation between particle physics and cosmology may constitute yet another successful ex...
Anthropic reasoning in multiverse cosmology and string theory
string theory multiverse cosmology Anthropic reasoning
2008/4/10
Anthropic arguments in multiverse cosmology and string theory rely on the weak anthropic principle (WAP). We show that the principle, though ultimately a tautology, is nevertheless ambiguous. It can b...
The claims of some authors to have introduced a new type of explanation in cosmology, based on the anthropic principle, are examined and found wanting. The weak anthropic principle is neither anthropi...
