In Episode 9 of ,,Wgryzamy się we Wszechświat" ("Let's chomp the Universe"), Dawid Jankowski interviews Boud Roukema about [...

(en) Is the Universe finite? Popular-level description of cosmic topology and curvature; and of void formation as a possible source providing effective dark energy as an artefact of negative average curvature. Audio in Polish. Subtitles in English...

Constructing an extension of Newton's theory which is defined on a non-Euclidean topology, called a non-Euclidean Newtonian theory, would be a powerful tool to study the influence of global topology on structure formation, especially studying the ...

The global topology of the spatial section of the Universe is currently unknown. It was first shown by Roukema et al (2007) that the existence of structure in the Universe implies effects of the global topology on local dynamics. Moreover, the eff...

Cosmic inhomogeneity and topology Lecture: II Lecture II - Overview of cosmic topology - observational approaches and the relation with inhomogeneities in the Universe. Recorded 29 August 2021 at Theory of Gravitation and Variation in Cosmol...

Cosmic inhomogeneity and topology: I Lecture I - Overview of research aiming at relativistically self-consistent models of the Universe in which expansion and structure formation together follow Einstein's equation. Recorded 27 August 2021 a...

If we want to know what's happening in the world as a whole based on governmental #OpenData, then we need to be able to check if those data are reliable. Which countries have unreliable data for the SARS-CoV-2 daily counts of the COVID-19 pande...
