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.
Astronomers detected a fast radio burst from a galaxy 8 billion light-years away. It's a new record, and the signal's source is still a mystery. Scientists detect 8 billion-year-old radio burst.
