In this paper, Michela looks at the DES Year 1 results and in particular considers the use of the Bayes factor along the Jeffreys scale in DES model selection. She draws attention to some of the advantages but also to some epistemic limits arising from the use of the Bayes factor. Link to Edinburgh Research […]

The debate in cosmology concerning LambdaCDM and MOND depends crucially on their respective ability of modelling across scales, and dealing with some of the specific problems that arise along the way. The main upshot of this article is to present three main problems facing multi-scale modelling in contemporary cosmology. The LambdaCDM model, which is the […]

I present a recent historical case from cosmology — the story of inflationary cosmology — and on its basis argue that solving explanatory problems is a reliable method for making progress in science. In particular, I claim that the success of inflationary theory at solving its predecessor’s explanatory problems justified the theory epistemically, even in […]

I discuss the formal implementation, interpretation, and justification of likelihood attributions in cosmology. I show that likelihood arguments in cosmology suffer from significant conceptual and formal problems that undermine their applicability in this context.
