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 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.

Map is one of the most precise measurements of how ‘stuff’ is distributed through the cosmos
2020 – After a 20-year-long survey, astrophysicists of the Sloan Digital Sky Survey publish the largest, most detailed 3D map of the universe so far, fill a gap of 11 billion years in its expansion history, and provide data which supports the theory of a flat geometry of the universe and confirms that different regions seem to be expanding at ...
The European Space Agency’s Euclid telescope aims to create the largest 3D map of the universe in the next six years. The observatory just completed the first piece.
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, ...
The history of the universe after inflation but before a time of about 1 second is largely unknown. [22] However, the universe is known to have been dominated by ultrarelativistic Standard Model particles, conventionally called radiation, by the time of neutrino decoupling at about 1 second. [23]
