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.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 ...
By this time, the universe will have expanded by a factor of approximately 10 2554. [131] 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 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.
By studying this ancient radiation, we can get a reading of what the Hubble constant would have been back when the universe began, and then use our knowledge of the laws of physics to functionally ...
Dark energy, believed to comprise approximately 69% of the universe, is a hypothesized form of energy permeating vast swathes of space that counteracts gravity and drives the universe's ...
c. 16th century BCE – Mesopotamian cosmology has a flat, circular Earth enclosed in a cosmic ocean. [1]c. 15th–11th century BCE – The Rigveda of Hinduism has some cosmological hymns, particularly in the late book 10, notably the Nasadiya Sukta which describes the origin of the universe, originating from the monistic Hiranyagarbha or "Golden Egg".
