Topic:cosmological parameters

Since 2020, aggregated from related topics

Cosmological parameters refer to the physical quantities that describe the characteristics and evolution of the universe as a whole. These parameters include things like the rate of expansion of the universe (Hubble constant), the density of dark matter and dark energy, the amount of baryonic matter, the curvature of space-time, and the age of the universe. By measuring and studying these parameters, researchers can gain insights into the fundamental properties and dynamics of the universe, as well as the origins and evolution of galaxies, stars, and other cosmic structures. The determination of cosmological parameters is a key goal of modern cosmology and is typically done through a combination of observations, simulations, and theoretical modeling.
