  Timeline of the Universe - Wikipedia, the free encyclopedia
It has been suggested that Timeline of the Big Bang be merged into this article or section.
This particular timeline of the Universe describes the events that have occurred and will occur according to prevailing scientific theory (specifically, the Big Bang theory).
As a result, this timeline is a work in progress.

 A Spacetime Map of the Universe
Due to the cosmological redshift, all distant galaxies appear "redshifted" in proportion to their distance: the greater their distance, the smaller the size of the Universe in which we see them as compared to our own, and hence the greater their redshift.
Assuming that the cosmological redshift has its origin in the size difference between the Universes of observer and observed, we can directly calculate the redshift we "should" see for each of the billion year intervals of the Spacetime Map, simply substituting the map's radius in years for the wavelength of light.
The "cosmological horizon problem" consists of the notion that widely separated regions of our Universe cannot have had enough time, given the finite velocity of light, to communicate with each other since their common origin in the Big Bang.

 Timeline of the Universe
This Timeline of the Universe is a brief summary of the events that have taken place and will take place in the Universe as we know it.
This timeline does not attempt to replace other more detailed references, such as the timeline of the Big Bang, but rather it attempts to be a starting point to help those find more detailed information on the how the Universe has evolved and likely may evolve.
The timeline, while illustrated and detailed, can be somewhat misleading.

Furthermore the structure of the filaments seen in cosmological galaxy surveys are very different than the structure of filaments seen in most plasma processes, and there is no proposed mechanism offered by the alternative model as to why the size of the structures has an upper-limit.
Any cosmological theory should be able to explain the near-isotropy of the CMB (Cosmic Microwave Background) and should also be able to explain the micro-Kelvin CMB anisotropies measured in detail by the WMAP mission.
The main argument against cosmological distances for quasars was that the energy required was far too high to be explainable by nuclear fusion, but this objection was removed by the proposal of gravity powered accretion disks.

The aim of this set of lectures is a systematic presentation of a 1+3 covariant approach to studying the geometry, dynamics, and observational properties of relativistic cosmological models.
They are designed to offer an overview of how the cosmological constant alters standard cosmology, and to discuss whether a non-zero cosmological constant exists today.
The aim of this lecture is to highlight two areas of recent progress in inflationary cosmology, namely reheating and the quantum theory of cosmological perturbations.

This timeline is in no way comprehensive of all the theorists and advancements that have been made in the field of cosmology, but instead intends to be a starting point for further exploration.
Many of the cosmological models of this time were drawn from religious or inspirational sources, and were not based on fact or science but on faith and belief.

By the sixth century A.D., Indian influence on the mainland is significant—prosperous kingdoms in Thailand adopt Indian political, cosmological, and religious practices, and Sanskrit inscriptions are found in eastern Kalimantan and western Java.
The mainland played a role in international trade as early as the fourth century B.C. when ships in the Bay of Bengal stopped at the Isthmus of Kra from which their goods were portaged to the Gulf of Thailand, thereby avoiding the lengthy and arduous voyage around the Malay Peninsula.
Ties with India are strengthened during the second to the fourth century A.D., and by the sixth century A.D., prosperous city-states or kingdoms flourish, adopting Indian political, cosmological, and religious thought.

 Open Questions: The Big Bang
The real mystery of dark energy, if it is represented by the cosmological constant, is that the latter is not vastly larger than it seems to be.
We will discuss elsewhere in more detail the processes that went on in the early universe to produce stars and galaxies, so this is an appropriate time to bring our overview of the first few hundred million years of the universe to a close.
The so-called "steady state" cosmological model which assumes time symmetry &ndash; that the universe has always looked about the same and always will – seems to conflict in a number of ways with what we actually see around us.

Perlmutter, at Lawrence Berkeley and Schmidt of Mount Stromlo and the Siding Spring Observatory in Australia found evidence in 1998 that the universe was expanding at an ever increasing rate.
It was completely unexpected, and justified what Einstein called his greatest blunder, the inclusion in the equations of a cosmological constant equivalent in effect to the existence of dark energy.
In that case, as the universe expands and the volume of space increases, astronomers say, the push because of dark energy will also increase, accelerating the galaxies away from one another faster and faster, leading to a dire dark future.
