Cosmology on small scales 2022

Popis výsledku v původním jazyce

One hundred years ago, Russian mathematician and physicist Alexander A. Friedmann applied the system of Einstein equations to the hypersphere with a time varying radius. In this way, he obtained a nonlinear ordinary differential equation which is called the Friedmann equation after him and serves now as a cornerstone of the standard cosmological model. Unfortunately, it is well known that this model exhibits a number of paradoxes. Thus, the main goal of the CSS 2022 conference is to discuss whether and how the Friedmann equation can be applied at the various spatial scales, from our local cosmic neighborhood up to the whole Universe, and if the existence of dark matter and dark energy are merely artifacts of the excessive extrapolations. So, it is timely to gather specialists from various branches of astronomy and astrophysics to discuss these issues.nConference topics: Mathematical aspects of the extrapolations used in cosmology, Arguments for and against dark energy, and revisiting the foundations of physics, Alternative models for dark matter and dark energy, A systematic discord in the value of the Hubble constant derived by different methods, Theoretical possibility and observational evidence for small-scale cosmological effects, Quantum effects on the early Universe and their observational imprints at the present time.
