Probabilistic inference in very large universes
Feraz Azhar, Alan H. Guth, Mohammad Hossein Namjoo
[Abridged] Some cosmological theories propose that the observable universe is a small part of a much larger universe in which parameters describing the low-energy laws of physics v…
Flows into de Sitter space from anisotropic initial conditions: An effective field theory approach
Feraz Azhar, David I. Kaiser
For decades, physicists have analyzed various versions of a ``cosmic no-hair" conjecture, to understand under what conditions a spacetime that is initially spatially anisotropic an…
Gauging Fine-Tuning
Feraz Azhar, Abraham Loeb
We introduce a mathematical framework for quantifying fine-tuning in general physical settings. In particular, we identify two distinct perspectives on fine-tuning, namely, a local…
Flows into inflation: An effective field theory approach
Feraz Azhar, David I. Kaiser
We analyze the flow into inflation for generic "single-clock" systems, by combining an effective field theory approach with a dynamical-systems analysis. In this approach, we const…
Spectra of conditionalization and typicality in the multiverse
Feraz Azhar
An approach to testing theories describing a multiverse, that has gained interest of late, involves comparing theory-generated probability distributions over observables with their…
Prediction and typicality in multiverse cosmology
Feraz Azhar
In the absence of a fundamental theory that precisely predicts values for observable parameters, anthropic reasoning attempts to constrain probability distributions over those para…
