Affleck–Dine mechanism

In the Affleck–dine mechanism is a mechanism postulated to explain baryogenesis within the primordial universe after the Big Bang. Thus, the advertisement mechanism can explain the asymmetry between matter and anti-matter in the modern Universe. It was proposed in 1985, Ian Affleck, Michael dine from Princeton University. In the theory of supersymmetry in particle physics, quarks and leptons have scalar partners, which carry baryon and lepton numbers. Since the latter decay into fermions in the early Universe, the total number of baryons, that they may lay presently observed excess of bary ...

                                               

Alpher–Bethe–Gamow paper

In physical cosmology, fer–Bethe–Gamow paper, or αβγ paper, was created by Ralph Alfer, then a physics PhD student, and his Advisor George Gamow. The work, which will be the subject of Alphers doctoral dissertation claimed that the Big Bang would create hydrogen, helium and heavier elements in the correct proportions to explain their abundance in the early Universe. While the original theory neglected a number of processes important for the formation of heavy elements, subsequent developments showed that Big Bang nucleosynthesis is consistent with the observed constraints on all critical e ...

                                               

Axis of evil (cosmology)

"Axis of evil" is the name of an anomaly in astronomical observations of the cosmic microwave background. The anomaly appears to break the plane of the Solar system and thus the location of the Land a higher value than would be expected by chance – the result of which was declared evidence of deviations from the Copernican principle. Cosmic microwave background the relic radiation signature is a direct large-scale view of the Universe, which can be used to determine whether our position or movement of matter. There has been much publicity about the analysis of the results of Wilkinson micr ...

                                               

Baade's Window

Baades window is a patch of sky with relatively low amounts of interstellar "dust" along the line of sight from Earth. This area is considered the "window" as the normally obscured galactic center of the milky Way is visible in this direction. It is named after the astronomer Walter Baade, who first recognized its significance. This area corresponds to one of the brightest visible patches of the milky Way. It is centered on galactic longitude L=1.02 degrees and galactic latitude b=-3.92 degrees.

                                               

Cosmic background radiation

The cosmic background radiation is electromagnetic radiation from the Big Bang. The origin of this radiation depends on the region of the spectrum, as observed. One component is the cosmic microwave background. This component is redshifted photons that have freely streamed from an epoch when the universe became transparent for the First time radiation. Its discovery and detail observations of its properties is one of the major conformations of the Big Bang. The discovery of cosmic background radiation indicates that the early Universe was dominated by radiation, the field of extremely high ...

                                               

Baryogenesis

In physical cosmology, baryogenesis is a hypothetical physical process that took place in the early Universe, which produced the baryon asymmetry, i.e. the imbalance of matter and antimatter in the observable Universe. One of the unsolved problems of modern physics is the predominance of matter over antimatter in the Universe. The universe as a whole seems to have positive nonzero baryon density, that is, matter exists. Since it is assumed that the particles in cosmology we see was created using the same physics we measure today, as a rule, it is expected that the total number of baryons m ...

The axis of evil is a controversial concept in itself: a direction that seems to be picked out by anisotropies in the cosmic microwave background.

Pino - logical board game which is based on tactics and strategy. In general this is a remix of chess, checkers and corners. The game develops imagination, concentration, teaches how to solve tasks, plan their own actions and of course to think logically. It does not matter how much pieces you have, the main thing is how they are placement!
