We can also look at the growth of large-scale structure, … See more As the universe expands, the density of radiation and ordinary dark matter declines more quickly than the density of dark energy (see equation of state) and, eventually, dark energy dominates. Specifically, when the scale of the universe doubles, … See more
WebRecently, there has been suggestions that the apparent accelerated expansion of the universe is due not to a cosmological constant, but rather to inhomogeneities in the distribution of matter. In this work, we investig… WebThe spatial behaviour of accelerated expansion of the universe is the most attractive topic of discussion among astrophysicists, and this expansion of the universe relies on dark matter (DM), ordinary matter (OM), and dark energy (DE) [1–4]. Therefore, General relativity (GR) provides the most satisfactory results and develops a basic
