Diagram of Evolution of the universe from the Big Bang (left) to the present. The timeline of the universe begins with the Big Bang, 13.799 ± 0.021 billion years ago, [1] and follows the formation and subsequent evolution of the Universe up to the present day. Each era or age of the universe begins with an "epoch," a time of significant change ...
The chronology of the universe describes the history and future of the universe according to Big Bang cosmology.. Research published in 2015 estimates the earliest stages of the universe's existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.
The universe remains manifest for 4.32 billion years and unmanifest for an equal length. Innumerable universes exist simultaneously. These cycles have and will last forever, driven by desires. [citation needed] Early Hebrew conception of the cosmos. [citation needed] The firmament, Sheol and tehom are depicted.
The timeline of the Universe lists events from its creation to its ultimate final state. For a timeline of the universe from the present to its presumed conclusion, see: Timeline of the far future; Chronology of the universe; Timeline of the early universe; Detailed logarithmic timeline; Graphical timeline from the Big Bang to the heat death of ...
Timeline of the expansion of the universe, where space, including hypothetical non-observable portions of the universe, is represented at each time by the circular sections. On the left, the dramatic expansion occurs in the inflationary epoch ; and at the center, the expansion accelerates (artist's concept; neither time nor size are to scale).

1501 – Indian astronomer Nilakantha Somayaji proposes a universe in which the planets orbit the Sun, but the Sun orbits the Earth. [64] c. 1514 – Nicolaus Copernicus states his heliocentric theory in Commentariolus.

Time interval, before the present time. a=annus (year) Period Event, invention or historical development 13.8 Ga – 11 Ga: Big Bang occurs when ordinary space and time develop from a primeval state (possibly a false vacuum) described by a quantum theory of gravity or "theory of everything". Infant universe cools as it begins expanding outward.
