General Relativity and Dynamical Universes

Fransson, Kajsa January 2021 (has links)
The aim of this report is to explore different models of cosmology, depending on components as matter, radiation and dark energy. To be able to investigate the behaviour and age of these model universes, it is necessary to solve the Friedmann equation. Therefore a substantial part of this thesis is a study of general relativity, including mathematical tools as Riemannian geometry and the concept of curved space-time. / Denna rapport ämnar att utforska olika kosmologiska modeller beroende på innehåll som materia, strålning och mörk energi. För att undersöka beteendet och åldern av dessa modellerade universa så är det nödvändigt att lösa Friedmann-ekvationen. Därför ägnas en betydande del av detta arbete åt att studera allmän relativitetsteori, med matematiska verktyg som Riemanngeometri och konceptet krökt rum-tid.
