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.
This future history and the timeline below assume the continued expansion of the universe. If space in the universe begins to contract, subsequent events in the timeline may not occur because the Big Crunch, the collapse of the universe into a hot, dense state similar to that after the Big Bang, will prevail.

A graphical view of the Cosmic Calendar, featuring the months of the year, days of December, the final minute, and the final second. The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.787 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.
The 1st-century bishop of Edessa predicted this date to be the birth date of the Antichrist and the end of the universe. [148] 23 Oct 1997 James Ussher: This 17th-century Irish archbishop predicted this date to be 6,000 years since creation and therefore the end of the world. [149] 31 Mar 1998 Hon-Ming Chen
By this time, the universe will have expanded by a factor of approximately 10 2554. [137] 1.1–1.2×10 14 (110–120 trillion) The time by which all stars in the universe will have exhausted their fuel (the longest-lived stars, low-mass red dwarfs, have lifespans of roughly 10–20 trillion years). [9]
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, ...
2025 has been consumed with cosmic chaos, and the year has just begun.. We kicked off the new year amidst three planetary retrogrades. Uranus, who is the revolutionary and rebellious celestial ...
The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. [1] The concept of an expanding universe was scientifically originated by physicist Alexander Friedmann in 1922 with the mathematical derivation of the Friedmann equations.
