In physical cosmology, the age of the universe is the time elapsed since the Big Bang.Astronomers have derived two different measurements of the age of the universe: [1] a measurement based on direct observations of an early state of the universe, which indicate an age of 13.787 ± 0.020 billion years as interpreted with the Lambda-CDM concordance model as of 2021; [2] and a measurement based ...
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.
Cosmic Calendar. The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.8 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science . In this visualization, the Big Bang took place at the beginning of January 1 at ...

Space and time, according to the prevailing ...
The Giant Arc is a large-scale structure discovered in June 2021 that spans 3.3 billion light years. [ 1] The structure of galaxies exceeds the 1.2 billion light year threshold, challenging the cosmological principle that at large enough scales the universe is considered to be the same in every place ( homogeneous) and in every direction ...
Graphical timeline from Big Bang to Heat Death. This is the timeline of the Universe from Big Bang to Heat Death scenario. The different eras of the universe are shown. The heat death will occur in around 1.7×10 106 years, if protons decay. [citation needed]
