Some of these decoupled photons are captured by other hydrogen atoms, the remainder remain free.

The exact timings of the first stars, galaxies, supermassive black holes, and quasars, and the start and end timings and progression of the period known as reionization, are still being actively researched, with new findings published periodically. However, by this time, matter had become far more spread out due to the ongoing expansion of the universe.
A typical simulation follows evolution of matter in a large In the early universe, dark matter gradually gathers in huge filaments under the effects of gravity, collapsing faster than ordinary (baryonic) matter because its collapse is not slowed by radiation pressure. As this field settled into its lowest energy state throughout the universe, it generated an enormous repulsive force that led to a rapid expansion of the metric that defines space itself. From 1 billion years, and for about 12.8 billion years, the universe has looked much as it does today. The quark epoch began approximately 10−12 seconds after the Big Bang.

To explain the observed homogeneity of the universe, the duration in these models must be longer than 10−32 seconds. Not now considered likely. The Virgo Consortium is an international grouping of scientists carrying out super computer simulations of the formation of galaxies, galaxy clusters, large-scale structure, and of the evolution of the intergalactic medium. Not only the light we receive from these objects

As yet, no Population III stars have been found, so our understanding of them is based on computational models of their formation and evolution.

it appears that all other galaxies fly away from us. Any explanation for this phenomenon must allow the Sakharov conditions related to baryogenesis to have been satisfied at some time after the end of cosmological inflation.

The chronology of the universe describes the history and future of the universe according to Big Bang cosmology. As the fluctuations grow in their amplitude, the evolution becomes too complex and theorists have to use computers to follow the subsequent evolution. Questions and comments: Andrey Kravtsov of structures, the expansion can be taken out so that the simulation box used as a measure of time. From this point on, and for several billion years to come, the presence of dark matter accelerates the formation of structure in our universe. In either case, these early generations of supernovae created most of the everyday elements we see around us today, and seeded the universe with them. the form of Cold Dark Matter (CDM) - massive collisionless Stars and galaxies are formed when dense regions of gas form due to the action of gravity, and this takes a long time within a near-uniform density of gas and on the scale required, so it is estimated that stars did not exist for perhaps hundreds of millions of years after recombination. The matter is thus represented by collisionless particles The hydrogen spin line is in the microwave range of frequencies, and within 3 million years,[citation needed] the CMB photons had redshifted out of visible light to infrared; from that time until the first stars, there were no visible light photons. Structure formation in the Big Bang model proceeds hierarchically, due to gravitational collapse, with smaller structures forming before larger ones. [44] The name is slightly inaccurate and is given for historical reasons: in fact the electrons and atomic nuclei were combining for the first time. It will continue to look similar for many more billions of years into the future. Part V.

In order to make it simpler to visualize the formation These tiniest fluctuations were stretched by many orders of Around the same time as recombination, existing pressure waves within the electron-baryon plasma—known as baryon acoustic oscillations—became embedded in the distribution of matter as it condensed, giving rise to a very slight preference in distribution of large-scale objects. / From this point onwards the physics of the early universe is much better understood, and the energies involved in the Quark epoch are directly accessible in particle physics experiments and other detectors. [39] (Much later, atomic hydrogen reacts with helium hydride to create molecular hydrogen, the fuel required for star formation.[39]). Ordinary matter gathers where dark matter is denser, and in those places it collapses into clouds of mainly hydrogen gas. These photons continue to interact frequently with charged particles, i.e., electrons, protons and (eventually) nuclei. Andrey Kravtsov As the universe expanded and cooled, it crossed transition temperatures at which forces separated from each other.

These may also lead to unpredictable changes to the state of the universe which would not be likely to be significant on any smaller timescale. This is a required element of, Cosmology traditionally has assumed a stable or at least, As a side-effect, the weak nuclear force and electromagnetic force, and their respective, This page was last edited on 14 October 2020, at 11:57. Questions and comments: Andrey Kravtsov Research is ongoing to understand this dark energy. As the Universe expands, galaxies become more and more distant from each other.

). The physics of this electrostrong interaction would be described by a Grand Unified Theory. [24] Similarly, deuterium fuses extremely easily; any alternative explanation must also explain how conditions existed for deuterium to form, but also left some of that deuterium unfused and not immediately fused again into helium. As a result, the universe was opaque or "foggy". on a piece of paper without This release of photons is known as photon decoupling. the processes operating on the smallest imaginable scales during the For example, in a later epoch, a side effect of one phase transition is that suddenly, many particles that had no mass at all acquire a mass (they begin to interact differently with the Higgs field), and a single force begins to manifest as two separate forces. But these are all still areas of active research.  (10%), where galaxy clusters were built from smaller galaxies that collided and Beyond this, all objects in the universe will cool and (with the possible exception of protons) gradually decompose back to their constituent particles and then into subatomic particles and very low level photons and other fundamental particles, by a variety of possible processes. due to the Doppler redshift effect.

Life would also have required a heat differential, rather than just uniform background radiation; this could be provided by naturally-occurring geothermal energy.
