Abstract
This thesis aims to explore how voids can contribute to the lack of uniformity in the measured Hubble constant (H0) values. This will be done firstly by setting up a model with spherical voids, whose particles are given a peculiar velocity and analyzing the radial velocity - distance relation with observers both inside and outside voids. Next, the radial velocity - distance relation will be analyzed in a ΛCDM N-body simulation. There, the difference in inferred H0 when observing from a void, filament, node, or wall will be investigated. Subsequently, dark matter halos will be identified from the ΛCDM simulation, and the radial velocity - distance relation will once more be analyzed, with observers again in the same features.
