CSS 2022 — Cosmology on Small Scales 2022: Dark Energy and the Local Hubble Expansion Problem
21 Sep 2022 - 24 Sep 2022 • Prague, Czech Republic
Organizer:
Institute of Mathematics, Czech Academy of Sciences
Abstract:
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. The main goal of the CSS 2022 conference is to discuss whether and how the Friedmann equation can be applied at 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 excessive extrapolations. So, it is timely to gather specialists from various branches of astronomy and astrophysics to discuss these issues.
