Quasargruppe ist größer, als es das kosmologische Prinzip oft "geklumpt" vor - sie bilden sogenannte Large Quasar Groups (LQG). 2/Quasarhaufen (U) Die derzeit massereichste Struktur ist ein Quasarhaufen, U (oder Huge Large Quasar Group), benannt nach der für alle. A large quasar group (LQG) of particularly large size and high membership has been identified in the DR7QSO catalogue of the Sloan Digital Sky Survey.

Darker colors indicate more quasars, lighter colors indicate fewer quasars. The LQG is clearly seen as a long chain of peaks indicated by black circles.

The red crosses mark the positions of quasars in a different and smaller LQG. The horizontal and vertical axes represent right ascension and declination, the celestial equivalent of longitude and latitude.

The map covers around At 4 billion light-years in length, the Large Quasar Group LQG is the largest known structure in the universe and is some times larger than the distance from the Milky Way to Andromeda.

An international team of astronomers, led by academics from the University of Central Lancashire UCLan , has found the largest known structure in the universe.

The large quasar group LQG is so large that it would take a vehicle traveling at the speed of light some 4 billion years to cross it.

Quasars are the nuclei of galaxies from the early days of the universe that undergo brief periods of extremely high brightness that make them visible across huge distances.

The modern theory of cosmology is based on the work of Albert Einstein, and depends on the assumption of the Cosmological Principle.

To give some sense of scale, our galaxy, the Milky Way, is separated from its nearest neighbor, the Andromeda Galaxy, by about 0. Based on the Cosmological Principle and the modern theory of cosmology, calculations suggest that astrophysicists should not be able to find a structure larger than Mpc.

But because it is elongated, its longest dimension is Mpc or 4 billion light years — some times larger than the distance from the Milky Way to Andromeda.

This is hugely exciting — not least because it runs counter to our current understanding of the scale of the universe. This is significant not just because of its size but also because it challenges the Cosmological Principle, which has been widely accepted since Einstein.

Inflation ended when the field decayed into ordinary particles in a process called reheating. There is currently insufficient observational evidence to explain why the universe contains far more baryons than antibaryons, a candidate explanation for this phenomenon must allow the Sakharov conditions to be satisfied at some time after the end of cosmological inflation.

While particle physics suggests asymmetries under which conditions are met. After cosmic inflation ends, the universe is filled with a quark—gluon plasma, from this point onwards the physics of the early universe is better understood, and the energies involved in the Quark epoch are directly amenable to experiment.

If supersymmetry is a property of our universe, then it must be broken at an energy that is no lower than 1 TeV, the electroweak symmetry scale.

At approximately 1 second after the Big Bang neutrinos decouple and begin traveling freely through space and this cosmic neutrino background, while unlikely to ever be observed in detail since the neutrino energies are very low, is analogous to the cosmic microwave background that was emitted much later.

The earliest phases of the Big Bang are subject to much speculation, in the most common models the universe was filled homogeneously and isotropically with a very high energy density and huge temperatures and pressures and was very rapidly expanding and cooling 3.

As the Universe expands, the density of electromagnetic radiation decreases more quickly than does that of matter because the energy of a photon decreases with its wavelength 4.

Panoramic view of the entire near-infrared sky reveals the distribution of galaxies beyond the Milky Way. Galaxies are color-coded by redshift.

The overall geometry of the universe is determined by whether the Omega cosmological parameter is less than, equal to or greater than 1.

Shown from top to bottom are a closed universe with positive curvature, a hyperbolic universe with negative curvature and a flat universe with zero curvature.

In a typical lightning strike, megajoule s of electric potential energy is converted into the same amount of energy in other forms, mostly light energy , sound energy and thermal energy.

Thermal energy is energy of microscopic constituents of matter, which may include both kinetic and potential energy.

The chronology of the universe describes the history and future of the universe according to Big Bang cosmology. The Hubble Ultra Deep Field s often showcase galaxies from an ancient era that tell us what the early Stelliferous Age was like.

Another Hubble image shows an infant galaxy forming nearby, which means this happened very recently on the cosmological timescale.

The physical size of the Hubble radius solid line as a function of the scale factor of the universe. The physical wavelength of a perturbation mode dashed line is shown as well.

The plot illustrates how the perturbation mode exits the horizon during cosmic inflation in order to reenter during radiation domination. If cosmic inflation never happened, and radiation domination continued back until a gravitational singularity , then the mode would never have exited the horizon in the very early universe.

Between entering the horizon and decoupling, the dark matter perturbation dashed line grows logarithmically, before the growth accelerates in matter domination.

On the other hand, between entering the horizon and decoupling, the perturbation in the baryon-photon fluid solid line oscillates rapidly. After decoupling, it grows rapidly to match the dominant matter perturbation, the dark matter mode.
