This time happens to correspond roughly to the time of the formation of the Solar System and the evolutionary history of life. Stelliferous Era: 150 Ma ~ 100 Ta [16] 20 ~ −0.99: 60 K ~ 0.03 K: The time between the first formation of Population III stars until the cessation of star formation, leaving all stars in the form of degenerate ...

In physical cosmology, the age of the universe is the time elapsed since the Big Bang: 13.8 billion years. [1]: Table 1 Astronomers have two different approaches to determine the age of the universe .
The timeline of the early universe outlines the formation and subsequent evolution of the Universe from the Big Bang (13.799 ± 0.021 billion years ago) [1] to the present day. An epoch is a moment in time from which nature or situations change to such a degree that it marks the beginning of a new era or age .
A similar analogy used to visualize the geologic time scale and the history of life on Earth is the Geologic Calendar. A graphical view of the Cosmic Calendar, featuring the months of the year, days of December, the final minute, and the final second
