Inhomogeneous Cosmologies (1st announcement), Torun, Poland

During 2-7 July 2017 we are gathering experts in inhomogeneous cosmology for a small workshop of about 30 participants at Nicolaus Copernicus University in Torun, the town where Copernicus was born. We wish to map out the most promising directions for analytical, numerical and observational investigations aimed to take into account both structure formation and cosmological expansion within the constraints of general relativity. A key motivating theme will be to discuss the claim, already investigated in numerous peer-reviewed papers, that “dark energy” as inferred from observations is an artefact of assuming an average Friedmannian expansion. New techniques in numerical relativity are beginning to open new perspectives on these questions. We expect vigorous, constructive debate between “one-percenters” and “order-unity” proponents, and practical hands-on sessions of free-licensed inhomogeneous cosmology
software packages.

We will post a formal announcement and registration details by early 2017 at
