Nonpareils are a decorative confections of tiny balls made with sugar and starch, traditionally an opaque white but now available in many colors. They are also known as hundreds and thousands in Australia, New Zealand, South Africa, [1] and the United Kingdom. In the United States, the same confectionery topping would generally be referred to ...
In modern physical cosmology, the cosmological principle is the notion that the spatial distribution of matter in the universe is uniformly isotropic and homogeneous when viewed on a large enough scale, since the forces are expected to act equally throughout the universe on a large scale, and should, therefore, produce no observable inequalities in the large-scale structuring over the course ...
An inhomogeneous cosmology is a physical cosmological theory (an astronomical model of the physical universe's origin and evolution) which, unlike the dominant cosmological concordance model, assumes that inhomogeneities in the distribution of matter across the universe affect local gravitational forces (i.e., at the galactic level) enough to skew our view of the Universe.

In the 1970s numerous studies showed that tiny deviations from isotropy in the CMB could result from events in the early universe. [33]: 8.5.1 Harrison, [34] Peebles and Yu, [35] and Zel'dovich [36] realized that the early universe would require quantum inhomogeneities that would result in temperature anisotropy at the level of 10 −4 or 10 −5.
Comparison of the evolution of the universe under Alfvén–Klein cosmology and the Big Bang theory. [1]Plasma cosmology is a non-standard cosmology whose central postulate is that the dynamics of ionized gases and plasmas play important, if not dominant, roles in the physics of the universe at interstellar and intergalactic scales.
The first attempt to model the distribution of galaxies with a fractal pattern was made by Luciano Pietronero and his team in 1987, [2] and a more detailed view of the universe's large-scale structure emerged over the following decade, as the number of cataloged galaxies grew larger.
The universe is believed to still be homogeneous enough that the theory is a good approximation on the largest scales, but on smaller scales more involved techniques, such as N-body simulations, must be used. When deciding whether to use general relativity for perturbation theory, note that Newtonian physics is only applicable in some cases ...
