A critical note on time in the multiverse
Cosmology Weyl principle Cosmic measurement problem
2016/6/15
In recent analyses of standard, single-universe, cosmology, it was pointed out that specific assumptions regarding the distribution and motion of matter must be made in order to set up the cosmologica...
Prediction and typicality in multiverse cosmology
Typicality anthropic principle multiverse cosmology dark matter
2016/6/12
In the absence of a fundamental theory that precisely predicts values for observable parameters, anthropic reasoning attempts to constrain probability distributions over those parameters in order to f...
The Cosmological Constant in the Quantum Multiverse
Cosmological Constant Quantum Multiverse
2011/10/17
Recently, a new framework for describing the multiverse has been proposed which is based on the principles of quantum mechanics. The framework allows for well-defined predictions, both regarding globa...
Will the cosmological multiverse, when described mathematically,have easily stated properties that are impossible to prove or disprove using mathematical physics? We explore this question by construct...
Multi-Stream Inflation: Bifurcations and Recombinations in the Multiverse
inflationary multiverse Multi-Stream Inflation
2010/3/18
In this Letter, we briefly review the multi-stream inflation scenario, and discuss its implications in the string theory landscape and the inflationary multiverse. In multi-stream inflation, the infla...
Understanding Deutsch's probability in a deterministic multiverse
Quantum mechanics Everett interpretation
2008/4/21
Difficulties over probability have often been considered fatal to the Everett interpretation of quantum mechanics. Here I argue that the Everettian can have everything she needs from `probability' wit...
Identity and uncertainty in Everett's multiverse
Everett many-worlds uncertainty probability identity branching
2008/4/14
In the current debate on the concept of probability in the Everett interpretation of quantum mechanics Saunders and Wallace argue for a notion of pre-measurement uncertainty whilst Greaves and Myrvold...
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...
